The PT7C4363 serial real-time clock is a low-power clock/calendar with a programmable square-wave output.

Address and data are transferred serially via a 2-wire bidirectional bus.

The clock/calendar provides seconds, minutes, hours, day, date, month, and year information.

Using external 32.768kHz quartz crystal.
Supports I2C-Bus's high speed mode (400 kHz).
Includes time (Hour/Minute/Second) and calendar (Year/Month/Date/Day) counter functions (BCD code).
Programmable square wave output signal.
Oscillator stop flag.
Low backup current: typ. 400nA at VDD=3.0V and TA=25°C.
Operating range: 1.3V to 5.5V.
