ANALOG DEVICES DS1629S+

DS1629S+ is a 2-wire digital thermometer and real-time clock. It integrates the critical functions of a real-time clock and a temperature monitor. Communication to DS1629 is accomplished via a 2-wire interface. The wide power supply range and minimal power requirement of DS1629 allow for accurate time/temperature measurements in battery-powered applications. The digital thermometer provides 9bit temperature readings which indicate temperature of device. 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 consists of six major components like direct-to-digital temperature sensor, RTC, 2-wire interface, data registers, thermal and clock alarm comparators, oscillator divider and buffer. Applications include PCs/PDAs, cellular telephones, office equipment, data loggers, or any thermally sensitive system.
