GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8E128K32 is a 4 Megabit
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 the
SMD and MIL-STD 883, making the AS8E128K32 ideally suited for
military or space applications.
The module is offered in a 1.075 inch square ceramic pin grid
array substrate. This package design provides the optimum space
saving solution for boards that accept through hole packaging.
The module is also 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.
