PT7C4363BQ数据手册集成电路（IC）的实时时钟规格书PDF

描述 Description

The PT7C4363BQ serial real-time clock is an automotive 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.
