Analog Devices / Maxim Integrated MAX31629 I2C Digital Thermometer & RTC
Analog Devices Inc. MAX31629 I2C Digital Thermometer and Real-Time Clock (RTC) integrates the critical functions of a real-time clock and a temperature monitor in a small-outline 8-pin TDFN package. Communication to the device is accomplished through an I2C interface. The wide power-supply range and minimal power requirement of the device allow for accurate time/temperature measurements in battery-powered applications. The digital thermometer provides 9-bit to 12-bit temperature readings that indicate the temperature of the device. No additional components are required; the device is truly a "temperature-to-digital" converter.
Features
- Measures temperatures from -55°C to +125°C or -67°F to +257°F
- Counts seconds, minutes, hours, day, day of the week, month, day of the month, and year
- Leap-year compensation through the year 2100
- ±2.0°C thermometer accuracy
- User programmable thermometer resolution to 9, 10, 11, or 12 Bits
- User definable thermostatic and time alarm settings
- Dedicated open-drain alarm output
- 32 bytes of SRAM for general data storage
- Data is read from/written to through an I2C serial interface (open-drain I/O lines)
- 2.2V to 5.5V wide power supply range
- 8-Pin TDFN package
Applications
- Data loggers and any thermally sensitive systems
- Industrial equipment
- Networking equipment
- Office equipment
