The UT8ER1M32 is a 32Mb, radiation hardened by design, high performance CMOS static RAM multichip module (MCM) that is functionally compatible with traditional 1Mx32 SRAM devices. Autonomous (master) and demanded (slave) scrubbing continues while deselected.
The device has a power-down feature that reduces power consumption by more than 90% when deselected, offered in a single package solution, and has superior SEU performance. Ideal for code execution in high performance microprocessors, microcontrollers and FPGAs.
