Download the MCP79512 datasheet PDF (MCP79510 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for battery-backed spi real-time clock/calendar.

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.

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.
