GENERAL DESCRIPTION
The AS8ERLC128K32 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 AS8ERLC128K32 ideally suited for military or
space applications.
The module is offered as a 68 lead 0.880 inch square ceramic
quad
fl
at pack. It has a max. height of 0.200 inch (non-shielded).
This package design is targeted for those applications which require
low profile SMT Packaging.
* contact factory for test reports. Micross does not guarantee or warrant these
performance levels, but references these third party reports.
