The MAX31629MTA+T is a I2C digital thermometer and real-time clock in 8 pin TDFN package. It integrates critical functions of a real-time clock and a temperature monitor in a small outline package and communication to 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 9bit to 12bit temperature readings that indicate the temperature of the device. The clock/calendar provides seconds, minutes, hours, day, day of the week, month, day of the month and year. 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 12hr or 24hr format with AM/PM indicator in 12hr mode. It is used in networking equipment, office equipment, data loggers & any thermally sensitive systems.
- Supply voltage range is 2.2V to 5.5V, 32bytes of SRAM for general data storage
- Operating temperature range from -55°C to 125°C
- Integration of temperature sensor and real time clock saves space and cost
- Real time clock with leap year compensation through the year 2100
- User programmability flexibly supports different application requirements
- Thermometer resolution is user programmable to 9bits, 10bits, 11bits or 12bits
- Thermostatic and time alarm settings are user definable, dedicated open-drain alarm output
- Industry standard serial interface works with a variety of common microcontrollers
- Data is read from/written to through an I2C serial interface (open-drain I/O lines)
