Digital temperature sensors for consumer apps

With integrated nonvolatile registers and integrated Serial EEPROM memory, the Atmel AT30TS750 devices enable user-configured settings to be retained across power cycles to simplify the system design, reduce processor start-up code, improve reliability and ensure proper operation.

Digital temperature sensors offer high accuracy and can measure temperatures over a wide range compared to other technologies such as thermocouples, thermistors and resistive thermal devices (RTDs), the company claims.

Additionally, digital temperature sensors can directly control other circuits in the system to offload the requirements in the microcontroller (MCU).

The Atmel temperature sensor range integrates 2k-, 4k- and 8k-bits of Serial EEPROM memory to store system parameters and user preference data.

The user can then access the EEPROM, which is fully functional and drop-in compatible with industry standard I2C serial EEPROMs.

The Atmel AT30TS750 range includes a group of five high-precision, digital temperature-sensor devices that are based on the industry-standard xx75 functionality offered by a number of vendors.

The inclusion of nonvolatile registers to permanently store device configuration settings offers system designers high flexibility.

All devices in the range measure and monitor temperature to address the thermal monitoring requirements of a variety of applications.

The parts are highly configurable to support a range of system applications.
