DESCRIPTION
The
ICSI
IC62VV25616L and IC62VV25616LL are low-power,
4.194,304 bit static RAMs organized as 262,144 words by 16
bits. They are fabricated using
ICSI
's high-performance CMOS
technology. This highly reliable process coupled with innova-
tive circuit design techniques, yields high-performance and
low power consumption devices.
When
CE
is HIGH (deselected) or both
LB
and
UB
are HIGH,
the device assumes a standby mode at which the power
dissipation can be reduced by using CMOS input levels.
Easy memory expansion is provided by using Chip Enable
Output and Enable inputs,
CE
and
OE.
The active LOW Write
Enable (WE) controls both writing and reading of the memory.
A data byte allows Upper Byte (UB) and Lower Byte (LB)
access.
The IC62VV25616L and IC62VV25616LL are packaged in the
JEDEC standare 44-pin TSOP-2 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.
