DS1629
2-Wire Digital Thermometer
and Real Time Clock
www.dalsemi.com
FEATURES
Measures temperatures from -55掳C to
+125掳C; Fahrenheit equivalent is -67掳F to
257掳F
Real time clock counts seconds, minutes,
hours, date of the month, month, day of the
week, and year with leap year compensation
through the year 2100
Thermometer accuracy is 卤2.0掳C (typ)
Thermometer resolution is 9 bits (expandable)
Thermostatic and time alarm settings are user
definable. Dedicated open-drain Alarm output
32 bytes SRAM for general data storage
Data is read from/written to via a 2-wire serial
interface. (open drain I/O lines)
Wide power supply range (2.2V - 5.5V)
Applications include personal
computers/PDAs, cellular telephones, office
equipment, dataloggers, or any thermally
sensitive system

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 鈥渢emperature-to-digital鈥?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.
