The MCP79400 general purpose I2C^TM Compatible real-time clock/calendar (RTCC) is highly integrated with memory and advanced features normally found in higher priced devices. These features include a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. 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. In addition to the SRAM memory, there a unique ID in a locked section of EEPROM that can be unlocked and programmed by the end user.

Dual alarms with single Interrupt Output that operates on VCC or VBAT
Clock Out frequencies of 32.768, 8.192 & 4.096 KHz and 1 Hz
1 ppm is approximately 86 milliseconds/day
Factory standard or custom ID programming available
