M48Z32V Datasheet - STMicroelectronics

SUMMARY DESCRIPTION
The M48Z32V ZEROPOWER® RAM is a 32 Kbit x 8, non-volatile static RAM that integrates powerfail 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 SUMMARY
■ INTEGRATED, ULTRA LOW POWER SRAM, AND POWER-FAIL 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
