Using Maxwell’s radiation-hard- ened RAD-PAK® 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 RAD-PAK 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. Logic Diagram |
