Overview
The DS1307ZN+T&R is a serial real-time clock (RTC) manufactured by Analog Devices Inc./Maxim Integrated. This component is a low-power, full binary-coded decimal (BCD) clock/calendar that also includes 56 bytes of non-volatile static RAM (NV SRAM). It operates through an I²C, bidirectional bus, providing seconds, minutes, hours, day, date, month, and year information. The clock/calendar automatically adjusts for months with fewer than 31 days and includes corrections for leap years. It can operate in either 24-hour or 12-hour format with an AM/PM indicator. The DS1307ZN+T&R features a built-in power-sense circuit that detects power failures and switches to a backup supply, ensuring continuous timekeeping operation.
