Maxwell Technologies' 33C408 high-density 4 Megabit SRAM microcircuit features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. Using Maxwell's radiation-hard-ened R_AD-P_AK^®packaging technology, the 33C408 realizes a high density, high performance, and low power consumption. Its fully static design elimi-nates the need for external clocks, while the CMOS circuitry reduces power consumption and provides higher reliability. The 33C408 is equipped with eight common input/output lines, chip select and output enable, allowing for greater system flex-ibility and eliminating bus contention. The 33C408 features the same advanced 512K x 8-bit SRAM, high-speed, and low-power demand as the com-mercial counterpart.

Maxwell Technologies' patented R_AD-P_AK packag-ing 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 S.
