M48Z58Y - 64-Kbit SRAM

Download the M48Z58Y datasheet PDF. This datasheet also covers the M48Z58 variant, as both devices belong to the same 64-kbit sram family and are provided as variant models within a single manufacturer datasheet.

General Description

The M48Z58/Y ZEROPOWER® RAM is an 8 Kbit 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.

Key Features

  • 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; 4.5 V ≤ VPFD ≤ 4.75 V.
  • M48Z35Y: 4.5 to 5.5 V; 4.2 V ≤ VPFD ≤ 4.5 V.
  • Self-contained battery in the CAPHAT™ DIP package.
  • Packaging includes a 28-lead SOIC and SNAPHA.
