The M48Z02 ZEROPOWER® RAM is a 2K x 8 non-volatile static RAM which is pin and functional compatible with the DS1220. A special 24-pin, 600mil DIP CAPHAT™ package houses the M48Z02 silicon with a long life lithium button cell to form a highly integrated battery backed-up memory solution. The button cell has sufficient capacity and storage life to maintain data functionality for an accumulated time period of at least 10 years in the absence of power over commercial operating temperature range.

The M48Z02 is a non-volatile pin and function equivalent to any JEDEC standard 2K 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.


  • Supply voltage: 4.75V to 5.5V
  • Ambient operating temperature: 0°C to 70°C (Grade 1)
  • Load capacitance: 100 pF
  • Input rise and fall times: ≤5ns
  • Input pulse voltages: 0V to 3V
  • Input and output timing ref. voltages: 1.5V
