DS1202 General Description

The DS1202 Serial Timekeeping Chip contains a real time clock/calendar and 24 bytes of static RAM. It communicateswith a microprocessor via a simple serial interface.The real time clock/calendar provides seconds,minutes, hours, day, date, month, and year information.The end of the month date is automatically adjusted for months with less than 31 days, including corrections for leap year. The clock operates in either the 24hour or 12hour format with an AM/PM indicator. Interfacing theDS1202 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: (1)RST (Reset), (2) I/O (Data line), and (3) SCLK (Serial clock). Data can be transferred to and from the clock/RAM one byte at a time or in a burst of up to 24 bytes.The DS1202 is designed to operate on very low power and retain data and clock information on less than 1 microwatt.
