MCP79511 - Battery-Backed SPI Real-Time Clock/Calendar

Download the MCP79511 datasheet PDF. This datasheet also covers the MCP79510 variant, as both devices belong to the same battery-backed spi real-time clock/calendar family and are provided as variant models within a single manufacturer datasheet.

General Description

The MCP795XX Real-Time Clock/Calendar (RTCC) tracks time using internal counters for hours, minutes, seconds, hundredths of a second, 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, hundredths of a second, day of week, date, 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 - ±259 ppm range.
  • Dual Programmable Alarms.
  • Clock Output Function with Selectable Frequency.
  • Power-Fail Timestamp: - Time logged on switchover to and f.
