6.2.1 Termination of unused pins

Table 5 shows how to terminate pins that are not used in the application. In many cases,

unused pins should be connected externally or configured correctly by software to

minimize the overall power consumption of the part.

Unused pins with GPIO function should be configured as outputs set to LOW with their

internal pull-up disabled. To configure a GPIO pin as output and drive it LOW, select the

GPIO function in the IOCON register, select output in the GPIO DIR register, and write a 0

to the GPIO PORT register for that pin. Disable the pull-up in the pin’s IOCON register.

In addition, it is recommended to configure all GPIO pins that are not bonded out on

smaller packages as outputs driven LOW with their internal pull-up disabled.

NXP Semiconductors LPC540xx

32-bit ARM Cortex-M4 microcontroller

7. Functional description

7.1 Architectural overview

The ARM Cortex-M4 includes three AHB-Lite buses: the system bus, the I-code bus, and

the D-code bus. The I-code and D-code core buses allow for concurrent code and data

accesses from different slave ports.

The LPC540xx uses a multi-layer AHB matrix to connect the ARM Cortex-M4 buses and

other bus masters to peripherals in a flexible manner that optimizes performance by

allowing peripherals that are on different slave ports of the matrix to be accessed

simultaneously by different bus masters.

7.2 ARM Cortex-M4 processor

The ARM Cortex-M4 is a general purpose, 32-bit microprocessor, which offers high

performance and very low power consumption. The ARM Cortex-M4 offers many new

features, including a Thumb-2 instruction set, low interrupt latency, hardware multiply and

divide, interruptable/continuable multiple load and store instructions, automatic state save

and restore for interrupts, tightly integrated interrupt controller with wake-up interrupt

controller, and multiple core buses capable of simultaneous accesses.

A 3-stage pipeline is employed so that all parts of the processing and memory systems

can operate continuously. Typically, while one instruction is being executed, its successor

is being decoded, and a third instruction is being fetched from memory.

7.3 ARM Cortex-M4 integrated Floating Point Unit (FPU)

The FPU fully supports single-precision add, subtract, multiply, divide, multiply and

accumulate, and square root operations. It also provides conversions between fixed-point

and floating-point data formats, and floating-point constant instructions.

The FPU provides floating-point computation functionality that is compliant with the

ANSI/IEEE Std 754-2008, IEEE Standard for Binary Floating-Point Arithmetic, referred to

as the IEEE 754 standard.

7.4 Memory Protection Unit (MPU)

The Cortex-M4 includes a Memory Protection Unit (MPU) which can be used to improve

the reliability of an embedded system by protecting critical data within the user

application.

The MPU allows separating processing tasks by disallowing access to each other's data,

disabling access to memory regions, allowing memory regions to be defined as read-only

and detecting unexpected memory accesses that could potentially break the system.

The MPU separates the memory into distinct regions and implements protection by

preventing disallowed accesses. The MPU supports up to eight regions each of which can

be divided into eight subregions. Accesses to memory locations that are not defined in the

7.10 System control

7.10.1 Clock sources

The LPC540xx supports one external and two internal clock sources:

•Free Running Oscillator (FRO).

•Watchdog oscillator (WDOSC).

•Crystal oscillator.

7.10.1.1 Free Running Oscillator (FRO)

The FRO 12 MHz oscillator provides the default clock at reset and provides a clean

system clock shortly after the supply pins reach operating voltage.

•12 MHz internal FRO oscillator, factory trimmed for accuracy, that can optionally be

used as a system clock as well as other purposes.

•Selectable 48 MHz or 96 MHz FRO oscillator, factory trimmed for accuracy, that can

optionally be used as a system clock as well as other purposes.

7.10.1.2 W atchdog oscillator (WDOSC)

The watchdog oscillator is a low-power internal oscillator. The WDOSC can be used to

provide a clock to the WWDT and to the entire chip. The low-power watchdog oscillator

provides a selectable frequency in the range of 6 kHz to 1.5 MHz. The accuracy of this

clock is limited to  40% over temperature, voltage, and silicon processing variations.

NXP Semiconductors LPC540xx

32-bit ARM Cortex-M4 microcontroller

7.10.6 Brownout detection

The LPC540xx includes a monitor for the voltage level on the VDD pin. If this voltage falls

below a fixed level, the BOD sets a flag that can be polled or cause an interrupt. In

addition, a separate threshold level can be selected to cause chip reset.

7.10.7 Safety

The LPC540xx includes a Windowed WatchDog Timer (WWDT), which can be enabled by

software after reset. Once enabled, the WWDT remains locked and cannot be modified in

any way until a reset occurs.

7.11 Power control

The LPC540xx support a variety of power control features. In Active mode, when the chip

is running, power and clocks to selected peripherals can be adjusted for power

consumption. In addition, there are three special modes of processor power reduction with

different peripherals running: sleep mode, deep-sleep mode, and deep power-down mode

that can be activated using the power API library from the SDK software package.

7.11.1 Sleep mode

In sleep mode, the system clock to the CPU is stopped and execution of instructions is

suspended until either a reset or an interrupt occurs. Peripheral functions, if selected to be

clocked can continue operation during Sleep mode and may generate interrupts to cause

the processor to resume execution. Sleep mode eliminates dynamic power used by the

processor itself, memory systems and related controllers, internal buses, and unused

peripherals. The processor state and registers, peripheral registers, and internal SRAM

values are maintained, and the logic levels of the pins remain static.

7.11.2 Deep-sleep mode

In deep-sleep mode, the system clock to the processor is disabled as in sleep mode. All

analog blocks are powered down by default but can be selected to keep running through

the power API if needed as wake-up sources. The main clock and all peripheral clocks are

disabled by default. The FRO is disabled.

Deep-sleep mode eliminates all power used by analog peripherals and all dynamic power

used by the processor itself, memory systems and related controllers, and internal buses.

The processor state and registers, peripheral registers, and internal SRAM values are

maintained, and the logic levels of the pins remain static.

GPIO Pin Interrupts, GPIO Group Interrupts, and selected peripherals such as USB0,

USB1, DMIC, SPI, I2C, USART, WWDT, RTC, Micro-tick Timer, and BOD can be left

running in deep sleep mode The FRO, RTC oscillator, and the watchdog oscillator can be

left running.In some cases, DMA can operate in deep-sleep mode.

7.11.3 Deep power-down mode

In deep power-down mode, power is shut off to the entire chip except for the RTC power

domain and the RESET pin. The LPC540xx can wake up from deep power-down mode

via the RESET pin and the RTC alarm. The ALARM1HZ flag in RTC control register

generates an RTC wake-up interrupt request, which can wake up the part. During deep

power-down mode, the contents of the SRAM and registers are not retained. All functional

pins are tri-stated in deep power-down mode.

NXP Semiconductors LPC540xx

32-bit ARM Cortex-M4 microcontroller

7.12 General Purpose I/O (GPIO)

The LPC540xx provides six GPIO ports with a total of up to 171 GPIO pins.

Device pins that are not connected to a specific peripheral function are controlled by the

GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate

registers allow setting or clearing any number of outputs simultaneously. The current level

of a port pin can be read back no matter what peripheral is selected for that pin.

7.12.1 Features

•Accelerated GPIO functions:

–GPIO registers are located on the AHB so that the fastest possible I/O timing can

be achieved.

–Mask registers allow treating sets of port bits as a group, leaving other bits

unchanged.

–All GPIO registers are byte and half-word addressable.

–Entire port value can be written in one instruction.

•Bit-level set and clear registers allow a single instruction set or clear of any number of

bits in one port.

•Direction control of individual bits.

•All I/O default to inputs after reset.

•All GPIO pins can be selected to create an edge or level-sensitive GPIO interrupt

request.

•One GPIO group interrupt can be triggered by a combination of any pin or pins.

7.13 Pin interrupt/pattern engine

The pin interrupt block configures up to eight pins from all digital pins for providing eight

external interrupts connected to the NVIC. The pattern match engine can be used in

conjunction with software to create complex state machines based on pin inputs. Any

digital pin, independent of the function selected through the switch matrix can be

configured through the SYSCON block as an input to the pin interrupt or pattern match

engine. The registers that control the pin interrupt or pattern match engine are located on

the I/O+ bus for fast single-cycle access.

7.14.4 SPI Flash Interface (SPIFI)

The SPI Flash Interface allows low-cost serial flash memories to be connected to the

LPC540xx microcontroller with little performance penalty compared to parallel flash

devices with higher pin count.

After a few commands configure the interface at startup, the entire flash content is

accessible as normal memory using byte, halfword, and word accesses by the processor

and/or DMA channels. Simple sequences of commands handle erasure and

programming.

Many serial flash devices use a half-duplex command-driven SPI protocol for device setup

and initialization and then move to a half-duplex, command-driven 4-bit protocol for

normal operation. Different serial flash vendors and devices accept or require different

commands and command formats. SPIFI provides sufficient flexibility to be compatible

with common flash devices and includes extensions to help insure compatibility with future

devices.

7.14.8.5 I2S-bus interface

The I2S bus provides a standard communication interface for streaming data transfer

applications such as digital audio or data collection. The I2S bus specification defines a

3-wire serial bus, having one data, one clock, and one word select/frame trigger signal,

providing single or dual (mono or stereo) audio data transfer as well as other

configurations. In the LPC540xx, the I2S function is included in Flexcomm Interface 6 and

Flexcomm Interface 7. Each of the Flexcomm Interface implements four I2S channel pairs.

The I2S interface within one Flexcomm Interface provides at least one channel pair that

can be configured as a master or a slave. Other channel pairs, if present, always operate

as slaves. All of the channel pairs within one Flexcomm Interface share one set of I2S

Product data sheet Rev. 1.9 — 23 October 2018 75 of 168

NXP Semiconductors LPC540xx

32-bit ARM Cortex-M4 microcontroller

signals, and are configured together for either transmit or receive operation, using the

same mode, same data configuration and frame configuration. All such channel pairs can

participate in a time division multiplexing (TDM) arrangement. For cases requiring an

MCLK input and/or output, this is handled outside of the I2S block in the system level

clocking scheme.

Features

•A Flexcomm Interface may implement one or more I2S channel pairs, the first of which

could be a master or a slave, and the rest of which would be slaves. All channel pairs

are configured together for either transmit or receive and other shared attributes. The

number of channel pairs is defined for each Flexcomm Interface, and may be from 0

to 4.

•Configurable data size for all channels within one Flexcomm Interface, from 4 bits to

32 bits. Each channel pair can also be configured independently to act as a single

channel (mono as opposed to stereo operation).

•All channel pairs within one Flexcomm Interface share a single bit clock (SCK) and

word select/frame trigger (WS), and data line (SDA).

•Data for all I2S traffic within one Flexcomm Interface uses the Flexcomm Interface

FIFO. The FIFO depth is 8 entries.

•Left justified and right justified data modes.

•DMA support using FIFO level triggering.

•TDM (Time Division Multiplexing) with a several stereo slots and/or mono slots is

supported. Each channel pair can act as any data slot. Multiple channel pairs can

participate as different slots on one TDM data line.

•The bit clock and WS can be selectively inverted.

•Sampling frequencies supported depends on the specific device configuration and

applications constraints (for example, system clock frequency and PLL availability.)

but generally supports standard audio data rates.

Remark: The Flexcomm Interface function clock frequency should not be above 48 MHz.

7.16 Counter/timers

7.16.1 General-purpose 32-bit timers/external event counter

The LPC540xx includes five general-purpose 32-bit timer/counters.

The timer/counter is designed to count cycles of the system derived clock or an

externally-supplied clock. It can optionally generate interrupts, generate timed DMA

requests, or perform other actions at specified timer values, based on four match

registers. Each timer/counter also includes two capture inputs to trap the timer value when

an input signal transitions, optionally generating an interrupt.

7.16.1.1 Features

•A 32-bit timer/counter with a programmable 32-bit prescaler.

•Counter or timer operation.

•Up to four 32-bit captures can take a snapshot of the timer value when an input signal

transitions. A capture event may also optionally generate an interrupt. The number of

capture inputs for each timer that are actually available on device pins may vary by

device.

•Four 32-bit match registers that allow:

–Continuous operation with optional interrupt generation on match.

–Stop timer on match with optional interrupt generation.

–Reset timer on match with optional interrupt generation.

–Shadow registers are added for glitch-free PWM output.

•For each timer, up to four external outputs corresponding to match registers with the

following capabilities (the number of match outputs for each timer that are actually

available on device pins may vary by device):

–Set LOW on match.

–Set HIGH on match.

Product data sheet Rev. 1.9 — 23 October 2018 79 of 168

event. This feature permits easy pulse width measurement by clearing the timer on

the leading edge of an input pulse and capturing the timer value on the trailing edge.

•Up to four match registers can be configured for PWM operation, allowing up to three

single edged controlled PWM outputs. (The number of match outputs for each timer

that are actually available on device pins may vary by device.)

7.16.2 SCTimer/PWM

The SCTimer/PWM allows a wide variety of timing, counting, output modulation, and input

capture operations. The inputs and outputs of the SCTimer/PWM are shared with the

capture and match inputs/outputs of the 32-bit general-purpose counter/timers.

The SCTimer/PWM can be configured as two 16-bit counters or a unified 32-bit counter. In

the two-counter case, in addition to the counter value the following operational elements

are independent for each half:

•State variable.

•Limit, halt, stop, and start conditions.

•Values of Match/Capture registers, plus reload or capture control values.

In the two-counter case, the following operational elements are global to the

SCTimer/PWM, but the last three can use match conditions from either counter:

7.16.3 Windowed WatchDog Timer (WWDT)

The purpose of the watchdog is to reset the controller if software fails to periodically

service it within a programmable time window.

7.16.3.1 Features

•Internally resets chip if not periodically reloaded during the programmable time-out

period.

•Optional windowed operation requires reload to occur between a minimum and

maximum time period, both programmable.

•Optional warning interrupt can be generated at a programmable time prior to

watchdog time-out.

•Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be

disabled.

•Incorrect feed sequence causes reset or interrupt if enabled.

•Flag to indicate watchdog reset.

•Programmable 24-bit timer with internal prescaler.

•Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 224 4) in

multiples of Tcy(WDCLK) 4.

•The Watchdog Clock (WDCLK) uses the WDOSC as the clock source.

7.16.4 Real Time Clock (RTC) timer

The RTC timer is a 32-bit timer which counts down from a preset value to zero. At zero,

the preset value is reloaded and the counter continues. The RTC timer uses the 32.768

kHz clock input to create a 1 Hz or 1 kHz clock.

7.16.5 Multi-Rate Timer (MRT)

The Multi-Rate Timer (MRT) provides a repetitive interrupt timer with four channels. Each

channel can be programmed with an independent time interval, and each channel

operates independently from the other channels.

7.16.5.1 Features

•24-bit interrupt timer.

•Four channels independently counting down from individually set values.

•Repeat and one-shot interrupt modes.

32-bit ARM Cortex-M4 microcontroller

7.16.6 Repetitive Interrupt Timer (RIT)

The repetitive interrupt timer provides a free-running 48-bit counter which is compared to

a selectable value, generating an interrupt when a match occurs. Any bits of the

timer/compare can be masked such that they do not contribute to the match detection.

The repetitive interrupt timer can be used to create an interrupt that repeats at

predetermined intervals.

7.16.6.1 Features

•48-bit counter running from the main clock. Counter can be free-running or can be

reset when an RIT interrupt is generated.

•48-bit compare value.

•48-bit compare mask. An interrupt is generated when the counter value equals the

compare value, after masking. This allows for combinations not possible with a simple

compare.

•Can be used for ETM debug time stamping.

7.17 12-bit Analog-to-Digital Converter (ADC)

The ADC supports a resolution of 12-bit and fast conversion rates of up to 5 Msamples/s.

Sequences of analog-to-digital conversions can be triggered by multiple sources. Possible

trigger sources are the SCTimer/PWM, external pins, and the ARM TXEV interrupt.

The ADC supports a variable clocking scheme with clocking synchronous to the system

clock or independent, asynchronous clocking for high-speed conversions

The ADC includes a hardware threshold compare function with zero-crossing detection.

The threshold crossing interrupt is connected internally to the SCTimer/PWM inputs for

tight timing control between the ADC and the SCTimer/PWM.

7.17.1 Features

•12-bit successive approximation analog to digital converter.

•Input multiplexing among up to 12 pins.

•Two configurable conversion sequences with independent triggers.

•Optional automatic high/low threshold comparison and “zero crossing” detection.

•Measurement range VREFN to VREFP (typically 3 V; not to exceed VDDA voltage

level).

•12-bit conversion rate of 5.0 Msamples/s. Options for reduced resolution at higher

conversion rates.

•Burst conversion mode for single or multiple inputs.

•Synchronous or asynchronous operation. Asynchronous operation maximizes

flexibility in choosing the ADC clock frequency, Synchronous mode minimizes trigger

latency and can eliminate uncertainty and jitter in response to a trigger.

7.18 CRC engine

The Cyclic Redundancy Check (CRC) generator with programmable polynomial settings

supports several CRC standards commonly used. To save system power and bus

bandwidth, the CRC engine supports DMA transfers.

7.18.1 Features

•Supports three common polynomials CRC-CCITT, CRC-16, and CRC-32.

–CRC-CCITT: x16 + x12 + x5 + 1

–CRC-16: x16 + x15 + x2 + 1

–CRC-32: x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1

•Bit order reverse and 1’s complement programmable setting for input data and CRC

sum.

•Programmable seed number setting.

•Supports CPU PIO or DMA back-to-back transfer.

•Accept any size of data width per write: 8, 16 or 32-bit.

–8-bit write: 1-cycle operation.

–16-bit write: 2-cycle operation (8-bit x 2-cycle).

–32-bit write: 4-cycle operation (8-bit x 4-cycle).

7.19 Temperature sensor

The temperature sensor transducer uses an intrinsic pn-junction diode reference and

outputs a CTAT voltage (Complement To Absolute Temperature). The output voltage

varies inversely with device temperature with an absolute accuracy of better than ±5 C

over the full temperature range (40 C to +105 C). The temperature sensor is only

approximately linear with a slight curvature. The output voltage is measured over different

ranges of temperatures and fit with linear-least-square lines.

After power-up, the temperature sensor output must be allowed to settle to its stable value

before it can be used as an accurate ADC input.

For an accurate measurement of the temperature sensor by the ADC, the ADC must be

configured in single-channel burst mode. The last value of a nine-conversion (or more)

burst provides an accurate result.

7.20 Security features

•OTP memories for AES key storage and customer use.

•Random number generator (RNG).

•Unique ID for each device.

7.20.1 SHA-1 and SHA-2

The Hash peripheral is used to perform SHA-1 and SHA-2 (256) based hashing. A hash

takes an arbitrarily large message or image and forms a relatively small fixed size

“unique” number called a digest. The data is fed by words from the processor, DMA, or

hosted access; the words are converted from little-endian (ARM standard) to big-endian

(SHA standard) by the block.

NXP Semiconductors LPC540xx

32-bit ARM Cortex-M4 microcontroller

7.20.1.1 Features

•Secure Hash Algorithm (SHA1/SHA2) module with dedicated DMA controller.

•Used with an HMAC to support a challenge/response or to validate a message.

•Can be used to verify external memory that has not been compromised.

7.21 Emulation and debugging

Debug and trace functions are integrated into the ARM Cortex-M4. Serial wire debug and

trace functions are supported. The ARM Cortex-M4 is configured to support up to eight

breakpoints and four watch points.

The ARM SYSREQ reset is supported and causes the processor to reset the peripherals,

execute the boot code, restart from address 0x0000 0000, and break at the user entry

point.

The SWD pins are multiplexed with other digital I/O pins. On reset, the pins assume the

SWD functions by default.

[1] The following applies to the limiting values:

a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive

static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated

maximum.

b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless

otherwise noted.

c) The limiting values are stress ratings only and operating the part at these values is not recommended and proper operation is not

guaranteed. The conditions for functional operation are specified in Table 20.

[2] Maximum/minimum voltage above the maximum operating voltage (see Table 20) and below ground that can be applied for a short time

(< 10 ms) to a device without leading to irrecoverable failure. Failure includes the loss of reliability and shorter lifetime of the device.

[3] The peak current is limited to 25 times the corresponding maximum current.

[4] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.

[5] VDD present or not present. Compliant with the I2C-bus standard. 5.5 V can be applied to this pin when VDD is powered down.

[6] Applies to all 5 V tolerant I/O pins except true open-drain pins.

[7] Including the voltage on outputs in 3-state mode.

[8] An ADC input voltage above 3.6 V can be applied for a short time without leading to immediate, unrecoverable failure. Accumulated

exposure to elevated voltages at 4.6 V must be less than 106 s total over the lifetime of the device. Applying an elevated voltage to the

ADC inputs for a long time affects the reliability of the device and reduces its lifetime.

9. Thermal characteristics

The average chip junction temperature, Tj (C), can be calculated using the following

equation:

(1)

•Tamb = ambient temperature (C),

•Rth(j-a) = the package junction-to-ambient thermal resistance (C/W)

•PD = sum of internal and I/O power dissipation

The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of

the I/O pins is often small and many times can be negligible. However it can be significant

in some applications.

11.2 Wake-up process

[1] Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply

voltages.

[2] The wake-up time measured is the time between when a GPIO input pin is triggered to wake the device up

from the low power modes and from when a GPIO output pin is set in the interrupt service routine (ISR)

wake-up handler.

[3] FRO enabled, all peripherals off. PLL disabled.

[4] RTC disabled. Wake up from deep power-down causes the part to go through entire reset

process. The wake-up time measured is the time between when the RESET pin is triggered to wake the

device up and when a GPIO output pin is set in the reset handler.

[5] FRO disabled.

11.11 I2C-bus

[1] Guaranteed by design. Not tested in production.

[2] Parameters are valid over operating temperature range unless otherwise specified. See the I2C-bus specification UM10204 for details.

[3] tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge.

[4] A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to

bridge the undefined region of the falling edge of SCL.

[5] Cb = total capacitance of one bus line in pF. If mixed with Hs-mode devices, faster fall times are allowed.

[6] The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at

250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines

without exceeding the maximum specified tf.

[7] In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should

allow for this when considering bus timing.

[8] The maximum tHD;DAT could be 3.45 s and 0.9 s for Standard-mode and Fast-mode but must be less than the maximum of tVD;DAT or

tVD;ACK by a transition time. This maximum must only be met if the device does not stretch the LOW period (tLOW) of the SCL signal. If

the clock stretches the SCL, the data must be valid by the set-up time before it releases the clock.

[9] tSU;DAT is the data set-up time that is measured with respect to the rising edge of SCL; applies to data in transmission and the

acknowledge.

[10] A Fast-mode I2C-bus device can be used in a Standard-mode I2C-bus system but the requirement tSU;DAT = 250 ns must then be met.

This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the

LOW period of the SCL signal, it must output the next data bit to the SDA line tr(max) + tSU;DAT = 1000 + 250 = 1250 ns (according to the

Standard-mode I2C-bus specification) before the SCL line is released. Also the acknowledge timing must meet this set-up time.

The actual USART bit rate depends on the delays introduced by the external trace, the

external device, system clock (CCLK), and capacitive loading. Excluding delays

introduced by external device and PCB, the maximum supported bit rate for USART

master synchronous mode is 24 Mbit/s, and the maximum supported bit rate for USART

slave synchronous mode is 12.5 Mbit/s.

12.2 12-bit ADC characteristics

[1] Based on characterization; not tested in production.

[2] Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply

voltages.

[3] The input resistance of ADC channels 6 to 11 is higher than ADC channels 0 to 5.

[4] Cia represents the external capacitance on the analog input channel for sampling speeds of

5.0 Msamples/s. No parasitic capacitances included.

[5] The differential linearity error (ED) is the difference between the actual step width and the ideal step width.

See Figure 41.

[6] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and

the ideal transfer curve after appropriate adjustment of gain and offset errors. See Figure 41.

[7] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the

straight line which fits the ideal curve. See Figure 41.

[1] Characterized through simulation. Not tested in production.

[2] The ADC default sampling time is 2.5 ADC clock cycles. To match a given analog source output

impedance, the sampling time can be extended by adding up to seven ADC clock cycles for a maximum

sampling time of 9.5 ADC clock cycles. See the TSAMP bits in the ADC CTRL register.

[3] Zo = analog source output impedance.

[4] For VDD  2.5 V, add one additional clock cycle to the values in Table 53.

12.2.1 ADC input impedance

Figure 42 shows the ADC input impedance. In this figure:

•ADCx represents slow ADC input channels 6 to 11.

•ADCy represents fast ADC input channels 0 to 5.

•R1 and Rsw are the switch-on resistance on the ADC input channel.

•If fast channels (ADC inputs 0 to 5) are selected, the ADC input signal goes through

Rsw to the sampling capacitor (Cia).

•If slow channels (ADC inputs 6 to 11) are selected, the ADC input signal goes through

R1 + Rsw to the sampling capacitor (Cia).

•Typical values, R1 = 487 , Rsw = 278 

•See Table 20 for Cio.

•See Table 52 for Cia.

13.2 Standard I/O pin configuration

Figure 45 shows the possible pin modes for standard I/O pins:

•Digital output driver: enabled/disabled.

•Digital input: Pull-up enabled/disabled.

•Digital input: Pull-down enabled/disabled.

•Digital input: Repeater mode enabled/disabled.

•Z mode; High impedance (no cross-bar currents for floating inputs).

For initial device revision 0A (Boot ROM version 21.0), the default configuration for the

standard I/O pins is PU mode (input mode, pull-up enabled, pull-up resistor pulls up pin to

VDD). For future device revision 1B (Boot ROM version 21.1), the default configuration for

the standard I/O pins is Z mode (high impedance; pull-up or pull-down disabled). See the

Errata sheet LPC540xx (IOCON.1) for more details. The weak MOS devices provide a

drive capability equivalent to pull-up and pull-down resistors. For future device revision 1B

(Boot ROM version 21.1), GPIO pins PIO0_12, PIO0_11, PIO0_2, PIO0_3, PIO0_4,

PIO0_5, and PIO0_6 have the input buffer enabled (DIGIMODE, bit 8 is enabled in

IOCON register) and will be floating by default. If unused, it is recommended to externally

terminate this pins to prevent leakage.

The glitch filter rejects pulses of typical 12 ns width.

13.3 Connecting power, clocks, and debug functions

Figure 46 shows the basic board connections used to power the LPC540xx devices,

connect the external crystal and the 32 kHz oscillator for the RTC, and provide debug

capabilities via the serial wire port.

(1) See Section 13.6 “XTAL oscillator” for the values of C1, C2, C3, and C4.

(2) Position the decoupling capacitors of 0.1 μF and 0.01 μF as close as possible to the VDD pin. Add one set of decoupling

capacitors to each VDD pin.

(3) Position the decoupling capacitors of 0.1 μF as close as possible to the VREFN and VDDA pins. The 10 μF bypass capacitor

filters the power line. Tie VDDA and VREFP to VDD if the ADC is not used. Tie VREFN to VSS if ADC is not used.

(4) Uses the ARM 10-pin interface for SWD.

(5) When measuring signals of low frequency, use a low-pass filter to remove noise and to improve ADC performance. Also see

Ref. 3.

(6) External pull-up resistors on SWDIO and SWCLK pins are optional because these pins have an internal pull-up enabled by

default on initial device revision 0A (Boot ROM version 21.0). For future device revision 1B (Boot ROM version 21.1), these pins

are in high Z mode (internal pull-up and pull-down disabled). See the Errata sheet LPC540xx (IOCON.1) for more details. For

future device revision 1B (Boot ROM version 21.1), GPIO pins SWDIO/PIO0_12, SWCLK/PIO0_11, PIO0_2, PIO0_3, PIO0_4,

PIO0_5, and PIO0_6 have the input buffer enabled (DIGIMODE, bit 8 is enabled in IOCON register) and will be floating by

default. If unused, it is recommended to externally terminate this pins to prevent leakage.

(7) Position the decoupling capacitor of 0.1 F as close as possible to the VBAT pin. Tie VBAT to VDD if not used.

13.4 I/O power consumption

I/O pins are contributing to the overall dynamic and static power consumption of the part.

If pins are configured as digital inputs, a static current can flow depending on the voltage

level at the pin and the setting of the internal pull-up and pull-down resistors. This current

can be calculated using the parameters Rpu and Rpd given in Ta b l e 2 0 for a given input

voltage VI. For pins set to output, the current drive strength is given by parameters IOH and

IOL in Ta ble 20, but for calculating the total static current, you also need to consider any

external loads connected to the pin.

I/O pins also contribute to the dynamic power consumption when the pins are switching

because the VDD supply provides the current to charge and discharge all internal and

external capacitive loads connected to the pin in addition to powering the I/O circuitry.

The contribution from the I/O switching current Isw can be calculated as follows for any

given switching frequency fsw if the external capacitive load (Cext) is known (see Tab l e 20

for the internal I/O capacitance):

Isw = VDD x fsw x (Cio + Cext)

13.5 RTC oscillator

In the RTC oscillator circuit, only the crystal (XTAL) and the capacitances CX1 and CX2

need to be connected externally on RTCXIN and RTCXOUT. See Figure 47.

For best results, it is very critical to select a matching crystal for the on-chip oscillator.

Load capacitance (CL), series resistance (RS), and drive level (DL) are important

parameters to consider while choosing the crystal. After selecting the proper crystal, the

external load capacitor CX1 and CX2 values can also be generally determined by the

following expression:

CX1 = CX2 = 2CL  (CPad + CParasitic)

Where:

CL - Crystal load capacitance

CPad - Pad capacitance of the RTCXIN and RTCXOUT pins (~3 pF).

CParasitic – Parasitic or stray capacitance of external circuit.

Although CParasitic can be ignored in general, the actual board layout and placement of

external components influences the optimal values of external load capacitors. Therefore,

it is recommended to fine tune the values of external load capacitors on actual hardware

board to get the accurate clock frequency. For fine tuning, output the RTC Clock to the

CLOCKOUT pin and optimize the values of external load capacitors for minimum

frequency deviation.

13.5.1 RTC Printed Circuit Board (PCB) design guidelines

•Connect the crystal and external load capacitors on the PCB as close as possible to

the oscillator input and output pins of the chip.

•The length of traces in the oscillation circuit should be as short as possible and must

not cross other signal lines.

•Ensure that the load capacitors CX1, CX2, and CX3, in case of third overtone crystal

usage, have a common ground plane.

•Loops must be made as small as possible to minimize the noise coupled in through

the PCB and to keep the parasitics as small as possible.

•Lay out the ground (GND) pattern under crystal unit.

•Do not lay out other signal lines under crystal unit for multi-layered PCB.

13.7 Suggested USB interface solutions

The USB device can be connected to the USB as self-powered device (see Figure 49) or

bus-powered device (see Figure 50).

On the LPC540xx, the USB_VBUS pin is 5 V tolerant only when VDD is applied and at

operating voltage level. Therefore, if the USB_VBUS function is connected to the USB

connector and the device is self-powered, the USB_VBUS pin must be protected for

situations when VDD = 0 V.

If VDD is always at operating level while VBUS = 5 V, the USB_VBUS pin can be

connected directly to the VBUS pin on the USB connector.

For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin,

precautions must be taken to reduce the voltage to below 3.6 V, which is the maximum

allowable voltage on the USB_VBUS pin in this case.

One method is to use a voltage divider to connect the USB_VBUS pin to the VBUS on the

USB connector. The voltage divider ratio should be such that the USB_VBUS pin is

greater than 0.7 VDD to indicate a logic HIGH while below the 3.6 V allowable maximum

voltage.

For the following operating conditions

VBUSmax = 5.25 V

VDD = 3.6 V,

the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.

The internal pull-up (1.5 k) can be enabled by setting the DCON bit in the

DEVCMDSTAT register to prevent the USB from timing out when there is a significant

delay between power-up and handling USB traffic. External circuitry is not required.

Two options exist for connecting VBUS to the USB_VBUS pin:

(1) Connect the regulator output to USB_VBUS. In this case, the USB_VBUS signal is HIGH whenever the part is powered.

(2) Connect the VBUS signal directly from the connector to the USB_VBUS pin. In this case, 5 V are applied to the USB_VBUS pin

while the regulator is ramping up to supply VDD. Since the USB_VBUS pin is only 5 V tolerant when VDD is at operating level,

this connection can degrade the performance of the part over its lifetime. Simulation shows that lifetime is reduced to 15 years

at Tamb = 45 °C and 8 years at Tamb = 55 °C assuming that USB_VBUS = 5 V is applied continuously while VDD = 0 V.
