Maxwell Technologies’ 79LV0408 multi-chip module (MCM)
memory features a greater than 100 krad (Si) total dose toler-
ance, depending upon space mission. Using Maxwell Technol-
ogies’
packaging technology, the 79LV0408 is the first radiation-
hardened 4 Megabit MCM EEPROM for space applications.
The 79LV0408 uses four 1 Megabit high-speed CMOS die to
yield a 4 Megabit product. The 79LV0408 is capable of in-sys-
tem electrical Byte and Page programmability. It has a 128
bytes Page Programming function to make its erase and write
operations faster. It also features Data Polling and a Ready/
Busy signal to indicate the completion of erase and program-
ming operations. In the 79LV0408, hardware data protection is
provided with the RES pin, in addition to noise protection on
the WE signal. 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, the R
greater than 100 krad (Si) radiation dose tolerance. This prod-
uct is available with screening up to Maxwell Technologies
self-defined Class K.
