LPSR019-0A 11/13/2001 IC62VV25616L IC62VV25616LL ICSI reserves the right to make changes to its products at any time without notice in order to improve design and supply the best possible product. We assume no responsibility for any errors which may appear in this publication. © Copyright 2001, Integrated Circuit Solution Inc. 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.
