Introduction

AI Translation

The DS1307 is a low-power, full BCD clock/calendar circuit with 56 bytes of user NV SRAM. Address and data are transferred serially via the I2C bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of month date is automatically adjusted for months with fewer than 31 days, including leap-year correction. The clock can operate in either 24-hour or 12-hour format with an AM/PM indicator. The DS1307 features a built-in power-sense circuit that detects power failures and automatically switches to the backup supply (battery) when a power failure is detected.
