  • The M48Z08/18 ZEROPOWER®RAM is an 8 K 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.
    The M48Z08/18 is a non-volatile pin and function equivalent to any JEDEC standard 8 K x 8 SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special write timing or limitations on the number of writes that can be performed.
    The 28-pin, 600 mil DIP CAPHAThouses the M48Z08/18 silicon with a long-life lithium button cell in a single package.

    Key Features

    • Integrated, ultra low power SRAM and power-fail 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 compatible with JEDEC standard 8 K x 8 SRAMs
    • RoHS compliant
      • Lead-free second level interconnect
