The ICSI IC62LV5128L and IC62LV5128LL is a low voltage,
524,288 words by 8 bits, CMOS SRAM. It is fabricated using
ICSI's low voltage, six transistor (6T), CMOS technology. The
device is targeted to satisfy the demands of the state-of-the-art
technologies such as cell phones and pagers.
When CE is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down with
CMOS input levels. Additionally, easy memory expansion is
provided by using Chip Enable and Output Enable inputs, CE
and OE. The active LOW Write Enable ( WE) controls both
writing and reading of the memory.
The IC62LV5128L and IC62LV5128LL are available in 32-pin
8*20mm TSOP-1, 8*13.4mm TSOP-1 and 48-pin 6*8mm TF-
