The PT7C4563BQ serial real-time clock is an automotive-grade low-power clock/calendar with a programmable square-wave output. It supports up to 125°C operating temperature.
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 the 24-hour format indicator.
Table 1 shows the basic functions of PT7C4563BQ. More details are shown in the Overview of Functions section.
