The SL1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus.The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. The SL1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

The SL8563x is a low-power CMOS real-time clock/calendar chip that features a programmable clock output, an interrupt output, and a power-fail detector. All addresses and data are serially transmitted via an I2C bus interface. The maximum bus speed is 400Kbits/s, and the embedded byte-addressable register automatically increments after each read or write operation
The DS1302 is a slow-speed chargeable realtime clock (RTC) chip featuring a real-time clock/calendar and 31 bytes of non-volatile static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar counts seconds, minutes, hours, days, weeks, months, and years, automatically adjusting month-end dates for months fewer than 31 days and incorporating leap year correction. The clock operates in either a 24-hour format or a 12-hour format with AM/PM indication. The 31 bytes of RAM can temporarily store important data. Synchronous serial communication simplifies interfacing the DS1302 with a microprocessor, requiring only three wires: (1) RST (reset), (2) I/O (data line), and (3) SCLK (serial clock). Data can be transmitted in single- byte format or multi-byte format up to 31 bytes at a time. The DS1302 operates at very low power consumption, preserving data and clock information with less than 1μW of power.
