DESCRIPTION
The
ICSI
IC62VV5128L and IC62VV5128LL 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 IC62VV5128L and IC62VV5128LL are available in 32-pin
8*20mm TSOP-1, 8*13.4mm TSOP-1 and 48-pin 6*8mm TF-
BGA.

Notes:
1. Stress 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.
