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
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 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
K.

... Software Data Protection Enable The 79LV0832 contains a software controlled write protection feature that allows the user to inhibit all write operations to the device. This is useful in protecting the device from unwanted write cycles due to uncontrollable circuit noise or inadvertent writes caused by minor bus contentions. Software data protection is enabled by writing the following data sequence to the EEPROM and allowing the write cycle period (t ...
