Maxwell Technologies' 32C408B high-speed 4 Megabit SRAM microcircuit features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. Using RAD-PAK(R) packaging technology, the 32C408B realizes higher density, higher performance and lower power consumption, and is well suited for high-speed system application. Its fully static design
eliminates the need for external clocks, while the CMOS cir-cuitry reduces power consumption and provides higher reli-ability. The 32C408B is equipped with eight common input/output lines, chip select and output enable, allowing for greater system flexibility and eliminating bus contention.

Maxwell Technologies' patented RAD-PAK packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age. In a GEO orbit, RAD-PAK can provides true greater than 100 krad (Si) total radiation dose tolerance; dependent upon space mission. The patented radiation-hardened RAD-PAK technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while provid-ing the required radiation shielding for a lifetime in orbit or a space mission. This product is available with packaging and screening up to Class S.
