FEATURES
DESCRIPTION
The M48Z58/58Y ZEROPOWER® RAM is an 8K x 8 non-volatile static RAM that integrates power-fail deselect circuitry and battery control logic on a single die. The monolithic chip is available in two special packages to provide a highly integrated battery backed-up memory solution.
■ INTEGRATED ULTRA LOW POWER SRAM, POWER-FAIL CONTROL CIRCUIT and BATTERY
■ READ CYCLE TIME EQUALS WRITE CYCLE TIME
■ AUTOMATIC POWER-FAIL CHIP DESELECT and WRITE PROTECTION
■ WRITE PROTECT VOLTAGES (VPFD = Power-fail Deselect Voltage):
– M48Z58: 4.50V ≤ VPFD ≤ 4.75V
– M48Z58Y: 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 and CRYSTAL
■ PIN and FUNCTION COMPATIBLE with JEDEC STANDARD 8K x 8 SRAMs
