GENERAL DESCRIPTION
The 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 con-
sumption and high reliability by employing 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 0.880 inch square ceramic
quad flat 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 more information. 2-sided shielding provided via Tungsten
lids on both sides. 6.5X typ. TID boost due to shielding. (Geostationary orbit)
Proven total dose 40K to 100K RADS. Micross can perform TID lot testing.
