GENERAL DESCRIPTION
The ASI AS5C1008 is a high speed, low power, 128K by
8-bit ruggedized plastic (COTS) CMOS Static RAM. It is fabri-
cated using high performance, CMOS technology. This highly
reliable process coupled with innovative circuit design tech-
niques, yields access times as fast as 15ns (Max) over the
military and industrial temperature ranges.
When Chip Enable (CE\) is HIGH, the device assumes a
standby mode at which the power dissipation can be reduced
down to 125mW (max) at CMOS input levels.
Easy memory expansion is provided by using asserted LOW
CE\ and asserted HIGH CE2, and asserted LOW write enable
(
WE\) controls both writing and reading of the memory.
TheAS5C1008 is pin-compatible with other 128K x 8
SRAM's in the SOJ package.
