M48Z512BV

3.3 V, 4 Mbit (512 K x 8 bit) ZEROPOWER® SRAM

Features

■ Integrated, ultra-low power SRAM, power-fail

control circuit, and battery

■ Conventional SRAM operation; unlimited

WRITE cycles

■ 10 years of data retention in the absence of

power

■ Automatic power-fail chip deselect and WRITE

protection

■ 3.0 to 3.6 V operation

– 2.9 V power-fail deselect

■ Pin and function compatible with JEDEC

standard 512 K x 8 SRAMs

■ PMDIP32 is an ECOPACK® package

■ For 5 V applications, refer to the M48Z512A

Description

The M48Z512BV ZEROPOWER® RAM is a non-

volatile, 4,194,304-bit static RAM organized as

524,288 words by 8 bits. The devices combine an

internal lithium battery, a CMOS SRAM and a

control circuit in a plastic, 32-pin DIP module.
