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
