产品概述

The DS1337S+T&R is an I2C serial real time clock (RTC) in 8 pin NSOIC package. It is a low power clock/calendar with two programmable time of day alarms and 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 leap year compensation valid up to 2100. The clock operates in either 24hour or 12hour format with AM/PM indicator. The DS1337 is fully accessible through serial interface and I2C operation is not provided below 1.8V. Timekeeping operation is maintained with VCC as low as 1.3V. The device is used in utility meter, vending machine, thermostat, modem, router, switch and server.
  • Supply voltage range from 1.8V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • 425nA time keeping current and 100nA data retention current (oscillator disabled)
  • Completely manages all timekeeping functions
  • Programmable square wave output defaults to 32KHz on power-up
  • Oscillator stop flag
  • Interfaces with most microcontrollers through I2C serial interface
  • Active supply current of 150µA and standby current of 1.5µA
  • SCL clock frequency of 400KHz (fast mode) and 100KHz (standard mode)
