Overview

The M48Z35/Y ZEROPOWER® RAM is a 32 K x 8, non-volatile static RAM that integrates powerfail 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 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)
  • M48Z35: VCC = 4.75 to 5.5 V;
  • 5 V ≤ VPFD ≤ 4.75 V
  • M48Z35Y: 4.5 to 5.5 V;
  • 2 V ≤ VPFD ≤ 4.5 V
  • Self-contained battery in the CAPHAT™ DIP package
  • Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
