產品總覽

MCP79410-I/MS is a serial battery-backed I2C real-time clock/calendar with SRAM, EEPROM and protected EEPROM. 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. The open-drain, multi-functional output can be configured to assert on an alarm match, to output a selectable frequency square wave or as a general purpose output. It is designed to operate using a 32.768KHz tuning fork crystal with external crystal load capacitors. On-chip digital trimming can be used to adjust for frequency variance caused by crystal tolerance and temperature. SRAM and timekeeping circuitry are powered from the backup supply when main power is lost, allowing the device to maintain accurate time and the SRAM contents.
  • Hours, minutes, seconds, day of week, day, month, year, leap year compensated to 2399
  • Dual programmable alarms
