MCP79411 - Real-Time Clock/Calendar

Download the MCP79411 datasheet PDF. This datasheet also covers the MCP79410 variant, as both devices belong to the same real-time clock/calendar family and are provided as variant models within a single manufacturer datasheet.

General Description

The MCP7941X Real-Time Clock/Calendar (RTCC) tracks time using internal counters for hours, minutes, seconds, days, months, years, and day of week.

Alarms can be configured on all counters up to and including months.

Key Features

  • Real-Time Clock/Calendar (RTCC): - Hours, minutes, seconds, day of week, day, month, year - Leap year compensated to 2399 - 12/24 hour modes.
  • Oscillator for 32.768 kHz Crystals: - Optimized for 6-9 pF crystals.
  • On-Chip Digital Trimming/Calibration: - ±1 PPM resolution - ±129 PPM range.
  • Dual Programmable Alarms.
  • Versatile Output Pin: - Clock output with selectable frequency - Alarm output - General purpose output.
  • Power-Fail Time-Stamp: - Ti.
