Battery-Backed I2C Real-Time Clock/Calendar with SRAM

The MCP7940N series of low-power Real-Time Clocks (RTC) uses digital timing compensation for an accurate clock/calendar, a programmable output control for versatility, and a power sense circuit that automatically switches to the backup supply. Using a low-cost 32.768kHz crystal, it tracks time using Battery-Backed Real-Time Clock/Calendar (RTCC)\nHours, Minutes, Seconds, Day of Week, Day, Month, Year\nLeap year compensated  to 2399\n12/24 hour modes\nOn-Chip Digital Trimming/Calibration\n1 PPM Resolution\n±129 PPM Range\nDual Programmable Alarms\nVersatile Output Pin\nClock output with selectab;
