DESCRIPTION
The 1+51 IC62C256 is a low power, 32,768 word by 8-bit
CMOS static RAM. It is fabricated using 1+51's high-
performance, low power CMOS technology.
When CS is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down to
250 µW (typical) at CMOS input levels.
Easy memory expansion is provided by using an active LOW
Chip Select (CS) input and an active LOW Output Enable (OE)
input. The active LOW Write Enable (WE) controls both writing
and reading of the memory.
The IC62C256 is pin compatible with other 32K x 8 SRAMs in
330mil SOP or 8*13.4mm TSOP-1 package.
