Product Overview

The DS1339U-33+ is a serial Real-time Clock (RTC) 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/date 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. This has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply, maintaining time, date and alarm operation.
  • Completely manages all timekeeping functions
  • Interfaces to most microcontrollers
  • Low-power operation extends battery backup run time
  • Underwriters Laboratories® (UL) recognized

Applications

Portable Devices, Consumer Electronics, Medical, Communications & Networking, Industrial, Metering

Warnings

Under no circumstances are negative undershoots, of any amplitude, allowed when device is in battery-backup mode.
