IN1307N is CMOS IC of Real Time Watch with Serial Interface, 56 Х 8 RAM.
The IN1307N Real Time Clock ic is a low power full BCD clock calendar plus 56 bytes of nonvolatile SRAM. The IN1307 has a built-in power sense circuit which detects power failures and automatically switches to the battery supply. Address and data are transferred serially via a 2-wire bi-directional bus. The 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 AM/PM indicator.
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
56 byte nonvolatile RAM for data storage
2-wire serial interface
Programmable square wave output signal
Automatic power fail detect and switch circuitry
Consumes less than 500 nA in battery backup mode
Industrial temperature range -40°C to +85°C
