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 employ-
ing 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 Pack-
aging.
