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.

FEATUREs
■ Integrated, ultra low power SRAM, and powerfail control circuit
■ READ cycle time equals WRITE cycle time
■ Automatic power-fail chip deselect and WRITE protection
■ WRITE protect voltages: (VPFD = Power-fail deselect voltage)
    – M48Z32V: 2.7V ≤ VPFD ≤ 3.0V
■ Ultra-low standby current
■ RoHS COMPLIANT
    – Lead-free second level interconnect
