DESCRIPTION
The DS1629 2-Wire Digital Thermometer and Real Time Clock integrates the critical functions of a real
time clock and a temperature monitor in a small outline 8-pin SOIC package. Communication to the
DS1629 is accomplished via a 2-wire interface. The wide power supply range and minimal power
requirement of the DS1629 allow for accurate time/temperature measurements in battery-powered
applications.
The digital thermometer provides 9-bit temperature readings which indicate the temperature of the device.
No additional components are required; the device is truly a “temperature-to-digital” converter.
The clock/calendar provides seconds, minutes, hours, day, date of the month, day of the week, month, and
year. The end of the month date is automatically adjusted for months with less than 31 days, including
corrections for leap years. It operates in either a 12- or 24-hour format with AM/PM indicator in 12-hour
mode.The crystal oscillator frequency is internally divided, as specified by device configuration. An
open-drain output is provided that can be used as the oscillator input for a microcontroller.
