Features and Applications

The M41ST85WMX6TR is a 3.6 V supply voltage, I2C combination serial real time clock, NVRAM supervisor and microprocessor supervisor, available in SOX-28 Package. 

It is built in a low-power CMOS SRAM process and has a 64-byte memory space with 44 bytes of NVRAM and 20 memory-mapped RTC registers. The RTC registers are configured in binary coded decimal (BCD) format.

Features:

  • Automatic battery switchover and WRITE protect for:
    • Internal serial RTC and 
    • External low power SRAM (LPSRAM)
  • 400 kHz I2C serial interface
  • 3.0/3.3 V operating voltage
    • VCC = 2.7 to 3.6 V
  • Ultralow battery supply current of 500 nA (max)
  • –40°C to +85°C operation
  • RoHS compliant
    • Lead-free second level interconnect
  • Serial RTC features:
    • 400 kHz I2C
    • 44 bytes of general purpose NVRAM
    • Counters for: seconds, minutes, hours, day, date, month, and year
    • Century
    • Tenths/hundredths of seconds
    • Clock calibration register allows compensation for crystal variations over temperature
    • 2.5 to 5.5 V oscillator operating voltage
  • Microprocessor supervisor features:
    • Programmable watchdog : 62.5 ms to 128 s time-out period
