M48Z08 - 64 Kbit (8 Kb x 8) ZEROPOWER SRAM

General Description

The M48Z08/18 ZEROPOWER® RAM is a 8 kbit x 8 non-volatile static RAM which is pin and function compatible with the DS1225.

The monolithic chip provides a highly integrated battery-backed memory solution.

Key Features

  • Integrated, ultra-low power SRAM and powerfail control circuit.
  • Unlimited WRITE cycles.
  • READ cycle time equals WRITE cycle time.
  • Automatic power-fail chip deselect and WRITE protection.
  • WRITE protect voltages (VPFD = power-fail deselect voltage):.
  • M48Z08: VCC = 4.75 to 5.5 V 4.5 V ≤ VPFD ≤ 4.75 V.
  • M48Z18: VCC = 4.5 to 5.5 V 4.2 V ≤ VPFD ≤ 4.5 V.
  • Self-contained battery in the CAPHAT™ DIP package.
  • Pin and function co.
