Dallas Ds1337S Real Time Clock IC; Date Format:YY-MM-DD; Time Format:12 or 24 hr; RTC Features:Square-Wave Output; Supply Voltage Min:1.8V; Supply Voltage Max:5.5V; Termination:SMD; Package/Case:8-SOIC; Operating Temperature Range:-400C to +850C

Description

The DS1337 serial real-time clock is a low-power clock/calendar with two programmable time-of-day alarms and a programmable square-wave output. Address and data are transferred serially through an I²C bus. The clock/calendar provides 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 AM/PM indicator.

The device is fully accessible through the serial interface while VCC is between 1.8V and 5.5V. I²C operation is not guaranteed below 1.8V. Timekeeping operation is maintained with VCC as low as 1.3V.
