The M48Z02-70PC1 is a part of M48Z02 series Battery Backed SRAM. It has an operating temperature ranging from -40 °C to +85 °C and it comes in PCDIP-28 Packaging.

The M48Z02 ZEROPOWER® RAM is a 2 K x 8 non-volatile static RAM which is pin and function compatible with the DS1220. A special 24-pin, 600 mil DIP CAPHAT™ package houses the M48Z02 silicon with a long-life lithium button cell to form a highly integrated battery-backed memory solution.


  • 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):
    • M48Z02: VCC= 4.75 to 5.5 V; 4.5 V ≤ VPFD ≤ 4.75 V
    • M48Z12: 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 2 K x 8 SRAMs
  • RoHS compliant
    • Lead-free second level interconnect
