GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8S128K32 is a 4 Mega-
bit CMOS SRAM Module organized as 128Kx32-bits and user
configurable to 256Kx16 or 512Kx8. The AS8S128K32 achieves
high speed access, low power consumption and high reliability
by employing advanced CMOS memory technology.
The military temperature grade product is suited for mili-
tary applications.
The AS8S128K32 is offered in a ceramic quad flatpack mod-
ule per SMD-5962-95595 with a maximum height of 0.140 inches.
This module makes use of a low profile, mutlichip module de-
sign.
This device is also offered in a 1.075 inch square ceramic
pin grid array per SMD 5692-93187, which has a maximum height
of 0.195 inches. This package is also a low profile, multi-chip
module design reducing height requirements to a minimum.
