Low Power CMOS SRAM
32K X8 Bits
UC62WV0256
-35/-55/-70
PIN DESCRIPTION
Name
Type
Function
A0 – A14
Input
Address inputs for selecting one of the 32768 x 8 bit words in the RAM
CE\
Input
CE\ is active LOW. Chip enable must be active when data read from or write to the device. If chip
enable is not active, the device is deselected and not in a standby power down mode. The DQ
pins will be in high impedance state when the device is deselected.
WE\
Input
The Write enable input is active LOW and controls read and write operations. With the chip
selected, when WE\ is HIGH and OE\ is LOW, output data will be present on the DQ pins, when
WE\ is LOW, the data present on the DQ pins will be written into the selected memory location.
OE\
Input
The output enable input is active LOW. If the output enable is active while the chip is selected
and the write enable is inactive, data will be present on the DQ pins and they will be enabled.
The DQ pins will be in the high impedance state when OE\ is inactive.
DQ0 – DQ7
I/O
These 8 bi0directional ports are used to read data from or write data into the RAM.

1. Stresses greater than those listed under ABSOLUTE
MAXIMUM RATINGS may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at these or any other conditions above those
indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for
extended periods may
affect reliability.
