I C Digital Input RTC with Alarm

DS1375

General Description

Features

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

♦ RTC Counts Seconds, Minutes, Hours, Day, Date,

Month, and Year with Leap-Year Compensation

Valid Up to 2100

♦ Two Programmable Alarms

♦ Programmable Square-Wave Output

♦ Operates from a 32.768kHz, 8.192kHz, 60Hz, or

50Hz Digital Clock Signal

♦ 16 Bytes of SRAM

♦ Fast (400kHz) I C Interface

transferred serially through an I C bidirectional bus.

♦ 1.7V to 5.5V Operation
