M48Z32V

3.3V, 256 Kbit (32 Kbit x8) ZEROPOWER® SRAM

STMicroelectronics 

SUMMARY DESCRIPTION

The M48Z32V ZEROPOWER® RAM is a 32 Kbit x

8, non-volatile static RAM that integrates power-

fail deselect circuitry and battery control logic on a

single die.

M48Z32V

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.

Note: NF, Pin 7 must be tied to VSS.
