POWER-FAIL CONTROL CIRCUIT and

BATTERY

■ UNLIMITED WRITE CYCLES

■ READ CYCLE TIME EQUALS WRITE CYCLE

TIME

■ AUTOMATIC POWER-FAIL CHIP DESELECT and

WRITE PROTECTION

■ WRITE PROTECT VOLTAGES

(VPFD = Power-fail Deselect Voltage):

– M48Z08: 4.50V ≤ VPFD ≤ 4.75V

– M48Z18: 4.20V ≤ VPFD ≤ 4.50V

■ SELF-CONTAINED BATTERY in the CAPHAT

DIP PACKAGE

■ PACKAGING INCLUDES a 28 LEAD SOIC

and SNAPHAT® TOP (to be Ordered

Separately)

■ SOIC PACKAGE PROVIDES DIRECT

CONNECTION for a SNAPHAT TOP which

CONTAINS the BATTERY
