DESCRIPTION
The ICSI IC62LV51216L and IC62LV51216LL are low-power,
8.388,608 bit static RAMs organized as 524,288 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 CE1 is HIGH or when CE2 is low (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, CE1, CE2 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 IC62LV51216L and IC62LV51216LL are packaged in the
JEDEC standare 44-pin TSOP-2 and 48-pin 8*10mm TF-BGA.
