DS1307 Real Time Clock (DIP) 8pin IC (IN1307 / IZ1307)

DS1307 Real Time Clock (RTC) IC - 8-Pin DIP with I2C & NV RAM

The DS1307 is a low-power Real Time Clock (RTC) IC. This 8-pin DIP package IC tracks seconds, minutes, hours, day, date, month, and year. It automatically adjusts for leap years up to 2100. Integrated 56 bytes of non-volatile (NV) RAM are available for data logging and time-stamping. Communication is handled via a 2-wire I2C serial interface. Automatic power-fail detection and switch circuitry ensure continuous operation during power interruptions. A programmable square-wave output signal is also available for system synchronization. Its 8-pin DIP package facilitates integration into embedded systems.
