General Description

The ACT–RS128K32 is a High

Speed 4 megabit CMOS SRAM

Multichip

Module

(MCM)

designed for full temperature

range, military, space, or high

reliability mass memory and

fast cache applications.

The MCM can be organized

as a 128K x 32 bits, 256K x 16

bits or 512k x 8 bits device and

is

input

and

output

TTL

compatible. Writing is executed

when the write enable (WE)

and chip enable (CE) inputs are

low. Reading is accomplished

when WE is high and CE and

output enable (OE) are both

low. Access time grades of

35ns and 45ns maximum are

standard.

The +5 Volt power supply

version is standard.

The products are designed for

operation over the temperature

range of -55°C to +125°C and

screened under the full military

environment.

DESC Standard

Military Drawing (SMD) part

numbers are pending.

The

ACT-RS128K32

is

manufactured

in

Aeroflex’s

80,000ft2

MIL-PRF-38534

certified facility in Plainview,

N.Y.
