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.
Voltage on Any Pin Relative to Ground –0.5V to +7.0V
Operating Temperature 0°C to 70°C or - 40°C to +85°C for industrial
Storage Temperature –55°C to +125°C
Soldering Temperature 260°C for 10 seconds (DIP)
See IPC/JEDEC Standard J-STD-020A for
Surface Mount Devices
* This is a stress rating only and functional operation of the device at these or any other conditions above
those indicated in the operation sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods of time may affect reliability.
■ Real time clock counts seconds, minutes
hours, date of the month, month, day of the
week, and year with leap year compensation
valid up to 2100
