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
