The M48T08-100PC1 TIMEKEEPER®RAM is an 8 K x 8 non-volatile static RAM and real-time clock which is pin and function compatible with the DS1643. The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory and real-time clock solution.

The M48T08/18/08Y 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. It has an Operating temperature ranges b/w -40 °C to 85 °C and available in a SO16 package.

Features:

  • Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
  • 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
  • Automatic power-fail chip deselect and WRITE protection
  • WRITE protect VPFD= power-fail deselect Voltage):
    • M48T08: VCC= 4.75 to 5.5 V; 4.5 V ≤ VPFD≤ 4.75 V
    • M48T18/T08Y: VCC= 4.5 to 5.5 V; 4.2 V ≤ VPFD≤ 4.5 V
  • Software controlled clock calibration for high accuracy applications
  • Self-contained battery and crystal in the CAPHAT™DIP package
  • Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
  • SOIC package provides direct connection for a snaphat top which contains the battery and crystal
  • Pin and function compatible with DS1643 and JEDEC standard 8 K x 8 SRAMs
  • RoHS compliant
    • Lead-free second level interconnect
