  1. Product information
M48T59Y-70PC1D 5.0 or 3.3 V, 64 Kbit (8 Kbit x 8) TIMEKEEPER® SRAM  Datasheet 
 
Description
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):
    • M48T59Y: VCC = 4.5 to 5.5 V 4.2 V ≤ VPFD ≤ 4.5 V
  • Microprocessor power-on reset (valid even during battery back-up mode)
  • Programmable alarm output active in the battery back-up mode
  • Battery low flag
