The Microchip Low power Real Time Clocks 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 32.768 kHz crystal, it tracks time using several internal registers. For communication, it uses the I2C™ bus. The clock/calendar automatically adjusts for months with fewer than 31 days, including corrections for leap years.
