DESCRIPTION
The ICSI IC62LV256 is a low power, 32, 768-word by 8-bit
static RAM. It is fabricated using ICSI's high-performance
CMOS double-metal technology.
When CE is HIGH (deselected), the device assumes a standby
mode at which the power dissipation is reduced to
20 µW (typical) with CMOS input levels.
Easy memory expansion is provided by using an active LOW
Chip Enable (CE) input and an active LOW Output Enable (OE)
input. The active LOW Write Enable (WE) controls both writing
and reading of the memory.
The IC62LV256 is pin compatible with other 32K x 8 SRAMs
in 300mil DIP and SOJ, 330mil SOP, and 8*13.4mm TSOP-1
packages.
