DESCRIPTION

The M48Z35AY/35AV ZEROPOWER® RAM is a 32 Kbit x8 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 in

tegrated battery backed-up memory solution.

■INTEGRATED ULTRA LOW POWER SRAM, POWER-FAIL CONTROL CIRCUIT and BATTERY

■READ CYCLE TIME EQUALS WRITE CYCLE TIME

■BATTERY LOW FLAG (BOK)

■AUTOMATIC POWER-FAIL CHIP DESELECT and WRITE PROTECTION

■WRITE PROTECT VOLTAGES (VPFD= Power-fail Deselect Voltage):

– M48Z35AY: 4.20V ≤VPFD ≤4.50V

– M48Z35AV: 2.7V≤VPFD ≤3.0V

■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 32K x8 SRAMs
