The PT7C4337A/4337AC serial real-time clock is a low-power clock/calendar with two programmable time-of-day alarms and 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. The date at the end of the month 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 device is fully accessible through the serial interface while VCC is between 1.8V and 5.5V. I2C operation is not guaranteed below 1.8V. Timekeeping operation is maintained with VCC as low as 1.2V.Table 1 shows the basic functions of PT7C4337A/ 4337AC. More details are shown in section: overview of functions.
