Description

Maxwell Technologies’ 33C108 high-density 1 Megabit SRAM microcircuit features a greater than 100 krad (Si) total dose tolerance. Using Maxwell’s radiation-hardened RAD-PAK®
packaging technology, the 33C108 realizes a higher density, higher performance, and lower power consumption. Its fully static design eliminates the need for external clocks, while the
CMOS circuitry reduces power consumption and provides higher reliability. The 33C108 is equipped with eight common input/output lines, chip select and output enable, allowing for greater system flexibility and eliminating bus contention. The 33C108 features the same advanced 128K x 8 SRAM, high-speed, and low-power demand as the commercial counter-part.

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 S.
