DESCRIPTION:
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® 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 circuitry reduces power consumption and provides higher reliability. The 32C408B is equipped with eight common input/ output lines, chip select and output enable, allowing for greater system flexibility and eliminating bus contention.
