GENERAL DESCRIPTION

The Austin Semiconductor, Inc. AS8ER128K32 is a 4 Megabit

Radiation Tolerant EEPROM Module organized as 128K x 32 bit.

User configurable to 256K x16 or 512Kx 8. The module achieves high

speed access, low power consumption and high reliability by

employing advanced CMOS memory technology.

The military grade product is manufactured in compliance to

MIL-STD 883, making the AS8ER128K32 ideally suited for military

or space applications.

The module is offered as a 68 lead 0.990 inch square ceramic

quad flat pack. It has a max. height of 0.200 inch. This package design

is targeted for those applications which require low profile SMT

Packaging.

* contact factory for test reports. ASI does not guarantee or warrant

these performance levels, but references these third party reports.
