79LV2040

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 radiation-hardened RAD-PAK^® MCM packaging 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</a> Polling and a Ready/Busy</a> signal to indicate the completion of erase and programming operations.In the 79LV2040, hardware data protection is provided with the RES</a> pin, in addition to noise protection on the WE</a> 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 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
