DS1375 pdf datasheet (I2C Digi

The DS1375 digital real-time clock (RTC) is a low-power
clock/calendar that does not require a crystal. The
device operates from a digital clock input pin at one of
four frequencies: 32.768kHz, 8.192kHz, 60Hz, or 50Hz.
It maintains 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 an
AM/PM indicator. Two programmable time-of-day/date
alarms, a programmable square-wave output, and 16
bytes of SRAM are provided. Address and data are
2
transferred serially through an I
C bidirectional bus.
