GENERAL DESCRIPTION
The Austin Semiconductor, Inc. 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 consumption 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 test reports. ASI does not guarantee or warrant
these performance levels, but references these third party reports.
