Product Overview

The DS1340Z-33+T&R is a I2C RTC with trickle charger in 8 pin NSOIC package. This is a low power clock/calendar with a trickle charger. Address and data are transferred serially through a I2C bidirectional 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 DS1340 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Reads and writes are inhibited while the clock continues to run. The device is programmed serially through an I2C bidirectional bus. It is used in point of sale equipment and telecommunications.
  • Supply voltage range is 2.97V to 5.5V
