DESCRIPTION
The DS1302 Trickle Charge Timekeeping Chip contains
a real time clock/calendar and 31 bytes of static RAM. It
communicates with 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 24–hour or 12–hour format with an AM/PM indicator.
Interfacing the DS1302 with a microprocessor is simpli-
fied 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 31
bytes. The DS1302 is designed to operate on very low
power and retain data and clock information on less
than 1 microwatt.
