Maxwell Technologies’ 33LV408 high-density 4 Megabit
SRAMmcrocircuit features a greater than 100 krad (Si) total
dose tolerance, depending upon space mssion. Using Max-

packaging technology, the
33LV408 realizes a high density, high performance, and low
power consumption. Its fully static design elimnates the need
for external clocks, while the CMOS circuitry reduces power
consumption and provides higher reliability. The 33LV408 is
equipped with eight common input/output lines, chip select
and output enable, allowing for greater systemflexibility and
elimnating bus contention. The 33LV408 features the same
advanced 512K x 8-bit SRAM high-speed, and low-power
demand as the commercial counterpart.
