DESCRIPTION:
Maxwell Technologies’ 79LV0832 multi-chip module (MCM)
memory features a greater than 100 krad (Si) total dose toler-
ance, dependent upon orbit. Using Maxwell Technologies’ pat-
ented radiation-hardened RAD-PAK® MCM packaging
technology, the 79LV0832 is the first radiation-hardened 8
megabit MCM EEPROM for space application. The 79LV0832
uses eight 1 Megabit high speed CMOS die to yield an 8
megabit product. The 79LV0832 is capable of in-system elec-
trical dword and page programmability. It has a 128 x 32 byte
page programming function to make its erase and write opera-
tions faster. It also features Data Polling and a Ready/Busy
signal to indicate the completion of erase and programming
operations. In the 79LV0832, hardware data protection is pro-
vided with the RES pin. Software data protection is imple-
mented using the JEDEC standard algorithm.
Maxwell Technologies' patented RAD-PAK® packaging technol-
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, RAD-PAK®‘ provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to MAxwell Technologies self-defined Class
K.
