GENERAL DESCRIPTION
The Austin Semiconductor, Inc. AS8E512K8 is a
4 Megabit CMOS EEPROM Module organized as 512K x 8-bits.
It is built with four 128K x 8 components and a single decoder.
The AS8E512K8 achieves high speed access, low power
consumption and high reliability by employing advanced CMOS
memory technology. Software data protection is implemented
using the JEDEC Optional Standard algorithm.
This military temperature grade product is ideally suited
for military and space applications requiring high reliability.
