Description
PT7C433833A Real-time Clock Module (I2C Bus)
The PT7C433833A serial real-time clock is a low-power clock/calendar with a programmable square-wave output and 56 bytes of nonvolatile RAM.
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.
