Maxwell Technologies’ 79LV2040 multi-chip module (MCM)

memory features a greater than 100 krad (Si) total dose toler-

ance, dependent upon orbit. Using Maxwell Technologies’ pat-

ented

technology, the 79LV2040 is the first radiation-hardened 8

megabit MCM EEPROM for space application. The 79LV2040

uses twenty 1 Megabit high speed CMOS die to yield a 20

megabit product. The 79LV2040 is capable of in-system elec-

trical byte and page programmability. It has a 128 x 40 page

programming function to make the erase and write operations

faster. It also features Data Polling and a Ready/Busy signal to

indicate the completion of erase and programming operations.

In the 79LV2040, hardware data protection is provided with

the RES pin, in addition to noise protection on the WE signal

and write inhibit on power on and off. Software data protection

is implemented using the JEDEC optional standard algorithm.

Maxwell Technologies' patented R

ogy incorporates radiation shielding in the microcircuit pack-

age. It eliminates the need for box shielding while providing

the required radiation shielding for a lifetime in orbit or space

mission. In a GEO orbit, R

krad (Si) radiation dose tolerance. This product is available

with screening up to Maxwell Technologies self-defined Class
