M48T59Y-70PC15.0 or 3.3 V, 64 Kbit (8 Kbit x 8) TIMEKEEPER® SRAM

The M48T559Y TIMEKEEPER® RAM is an 8K x 8 non-volatile static RAM and real time clock. The monolithic chip is available in the SNAPHAT package to provide a highly integrated battery backedup memory and real time clock solution.

Features

  • Integrated ultra low power SRAM, real-time clock, power-fail control circuit, and battery
  • Frequency test output for real-time clock software calibration
  • Automatic power-fail chip deselect and WRITE protection
  • WRITE protect voltages (VPFD = Power-fail deselect voltage):
    • M48T59: VCC = 4.75 to 5.5 V 4.5 V ≤ VPFD ≤ 4.75 V
    • M48T59Y: VCC = 4.5 to 5.5 V 4.2 V ≤ VPFD ≤ 4.5 V
    • M48T59V(a): VCC = 3.0 to 3.6 V 2.7 V ≤ VPFD ≤ 3.0 V
  • Self-contained battery and crystal in the CAPHAT™ DIP package
  • Packaging includes a 28-lead SOIC and SNAPHAT® top (to be ordered separately)
  • Microprocessor power-on reset (valid even during battery back-up mode)
  • Programmable alarm output active in the battery back-up mode
  • Battery low flag
  • RoHS compliant
    • Lead-free second level interconnect
