The M48T12-70PC1 is a part of M48T12 series Battery Backed SRAM. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOH-28 Packaging.

The M48T12 TIMEKEEPER® RAM is a 2 Kb x 8 non-volatile static RAM and real-time clock which is pin and functional compatible with the DS1642.

A special 24-pin, 600 mil DIP CAPHAT™ package houses the M48T02/12 silicon with a quartz crystal and a long life lithium button cell to form a highly integrated battery-backed memory and real-time clock solution.


  • Integrated, ultra low power SRAM, real-time clock, and power-fail control circuit
  • BYTEWIDE. RAM-like clock access
  • BCD coded year, month, day, date, hours, minutes, and seconds
  • Typical clock accuracy of ±1 minute a month, at 25 °C
  • Software controlled clock calibration for high accuracy applications
  • Automatic power-fail chip deselect and WRITE protection
  • WRITE protect voltages (VPFD = Power-fail deselect voltage):
    •  M48T02: VCC = 4.75 to 5.5 V, 4.5 V ≤ VPFD ≤ 4.75 V
    •  M48T12: VCC = 4.5 to 5.5 V, 4.2 V ≤ VPFD ≤ 4.5 V
  • Self-contained battery and crystal in the CAPHAT. DIP package
  • Pin and function compatible with JEDEC standard 2 K x 8 SRAMs
  • RoHS compliant
  • .Lead-free second level interconnect
