GENERAL DESCRIPTION
SQB No. 703SQB
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 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.
