Description
The PT7C4563 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.
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 PT7C4563. More
details are shown in section: overview of functions.
