DS1629S+T&R

DS1629S+T&R 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 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. The clock/calendar provides seconds, minutes, hours, day, date of the month, day of the week, month, and year. It consists of six major components like direct-to-digital temperature sensor, real-time clock, 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.

• Thermometer accuracy is ±2.0°C (typ)
• Thermometer resolution is 9bits (expandable)
• Thermostatic and time alarm settings are user definable; dedicated open-drain alarm output
• 32bytes SRAM for general data storage
• Data is read from/written to via a 2-wire serial interface (open drain I/O lines)
• No additional components are required; the device is truly a “temperature-to-digital” converter
• Supply voltage range from 2.2 to 5.5V
• DS1629 thermometer error is ±2.0°C max at -10°C to +85°C, 2.7V ≤ VDD ≤ 5.5V
• 8 SO package
• Measures temperatures from -55°C to +125°C
