Using Maxwell Technol- ogies’ patented radiation-hardened RAD-PAK® MCM packaging technology, the 79C0408 is the first radiation-hard- ened 4 Megabit MCM EEPROM for space applications. The 79C0408 uses four 1 Megabit high-speed CMOS die to yield a 4 Megabit product. The 79C0408 is capable of in-system elec- trical 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 79C0408, 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 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, the RAD-PAK® package provides greater than 100 krad (Si) radiation dose tolerance. This prod- uct is available with screening up to Class K. 128Kx 8 128Kx 8 128Kx 8 128Kx 8 I/O 0-7 A 0-16 WE R/B RES OE CE 1 CE 2 CE 3 CE 4 FEATURES: Logic Diagram |
