GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8E32K32 is a 1 Megabit
EEPROM Modules organized as 32K x 32 bit. User configurable to
64K x16 or 128Kx 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 AS8E32K32 ideally suited
for military or space applications.
The module is offered in a 1.090 sq inch 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 sq. inch ceramic
quad flatpack. It has a max. height of 0.200 inch. This package
design is targeted for those applications which require low profile
SMT Packaging.

DEVICE IDENTIFICATION
An extra 64 bytes of EEPROM memory is available on each die
for user identification. By raising A9 to 12 V +/- 0.5V and using
address locations 7FC0H to 7FFFH the bytes may be written to
or read from in the same manner as the regular memory array.
