Data Sheets:

The MCP7940M I2CTM compatible real-time clock/calendar (RTCC) includes SRAM and a digital trimming circuit for accuracy which is normally found in higher priced devices. Using a low-cost 32,768 kHz crystal or other clock source, time is tracked in either a 12-hour or 24-hour format with an AM/PM indicator and timing to the second, minute, hour, day of the week, day, month and year. As an interrupt or wakeup signal, a multifunction open drain output can be programmed as an Alarm Out or as a Clock Out that supports 4 selectable frequencies.

  • Hours, Minutes, Seconds, Day of Week, Day, Month, Year
  • Leap year compensated  to 2399
  • 12/24 hour modes
  • 1 PPM Resolution
  • ±129 PPM Range
  • Dual Programmable Alarms
  • Clock output with selectable frequency
  • Alarm output
  • General Purpose output
  • 64 Bytes SRAM
  • I2C Clock Frequency up to 400 kHz
  • Operating Voltage 1.8V to 5.5V
  • Low Typical Timekeeping Current
