Summary

The M48Z35AV ZEROPOWER® RAM is a 32Kbit 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.

Features

■ 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 voltage: (VPFD= Power-fail deselect voltage)

– 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)

■ Pin and function compatible with JEDEC standard 32Kbit x 8 SRAMs

■ SOIC package provides direct connection for a SNAPHAT top which contains the battery

■ RoHS compliant

– Lead-free second level interconnect
