Description

Maxwell Technologies’ 79LV0408 multi-chip module (MCM) memory features a greater than 100 krad (Si) total dose tolerance, dependent upon orbit. Using Maxwell Technologies’ patented radiation-hardened RAD-PAK® MCM 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-system 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 programming
operations. In the 79LV0408, 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 RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. 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 Class K.
