DESCRIPTION

The

524,288 words by 8 bits, CMOS SRAM. It is fabricated using

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.
