Summary

Summary

The M48Z32V ZEROPOWER® RAM is a 32K x 8, non-volatile static RAM that integrates

power-fail deselect circuitry and battery control logic on a single die.

The 44-pin, 330mil SOIC provides a battery pin for an external, user-supplied battery. This is

all that is required to fully non-volatize the SRAM.
