Functional Description
The CY62146EV30 is a high performance CMOS static RAM
organized as 256K words by 16 bits. This device features an
advanced circuit design designed to provide an ultra low active
current. Ultra low active current is ideal for providing More
Battery Life (MoBL®) in portable applications such as cellular
telephones. The device also has an automatic power down
feature that significantly reduces power consumption by 80
percent when addresses are not toggling.The device can also be
put into standby mode reducing power consumption by more
than 99 percent when deselected (CE HIGH). The input and
output pins (I/O0 through I/O15) are placed in a high impedance
state when the device is deselected (CE HIGH), outputs are
disabled (OE HIGH), both Byte High Enable and Byte Low
Enable are disabled (BHE, BLE HIGH), or a write operation is in
progress (CE LOW and WE LOW).
To write to the device, take Chip Enable (CE) and Write Enable
(WE) input LOW. If Byte Low Enable (BLE) is LOW, then data
from I/O pins (I/O0 through I/O7) is written into the location
specified on the address pins (A0 through A17). If Byte High
Enable (BHE) is LOW, then data from the I/O pins (I/O8 through
I/O15) is written into the location specified on the address pins
(A0 through A17).
To read from the device, take Chip Enable (CE) and Output
Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If
Byte Low Enable (BLE) is LOW, then data from the memory
location specified by the address pins appears on I/O0 to I/O7. If
Byte High Enable (BHE) is LOW, then data from memory
appears on I/O8 to I/O15. See the Truth Table on page 11 for a
complete description of read and write modes.

Notes
14. Test conditions for all parameters other than tri-state parameters assume signal transition time of 3 ns (1 V/ns) or less, timing reference levels of VCC(typ)/2, input
pulse levels of 0 to VCC(typ), and output loading of the specified IOL/IOH as shown in the Figure 3 on page 5.
15. In an earlier revision of this device, under a specific application condition, READ and WRITE operations were limited to switching of the byte enable and/or chip
enable signals as described in the Application Notes AN13842 and AN66311. However, the issue has been fixed and in production now, and hence, these Application
Notes are no longer applicable. They are available for download on our website as they contain information on the date code of the parts, beyond which the fix has
been in production.
16. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given
device.
17. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
18. The internal write time of the memory is defined by the overlap of WE, CE = VIL, BHE and/or BLE = VIL. All signals must be ACTIVE to initiate a write and any of
these signals can terminate a write by going INACTIVE. The data input setup and hold timing must be referenced to the edge of the signal that terminates the write
19. The minimum write pulse width for Write Cycle No. 3 (WE controlled, OE LOW) should be sum of tHZWE and tSD.

24. Data I/O is high impedance if OE = VIH.
25. If CE goes HIGH simultaneously with WE = VIH, the output remains in a high impedance state.
26. During this period, the I/Os are in output state and input signals must not be applied.
