Embedded World, Nuremberg, Germany: A family of high-precision digital temperature sensors developed by Atmel features both integrated nonvolatile registers and integrated serial EEPROM memory. With this combination, user-configured settings can be retained across power cycles to simplify system design, reduce processor startup code, improve reliability, and ensure proper operation.
The digital temperature sensors can measure temperatures over a wide range. Moreover, they’re able to directly control other circuits in the system to offload the requirements in the microcontroller.
The sensor family integrates 2kb, 4kb, and 8kb 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 standard I2C serial EEPROMs.
A group of five digital temperature-sensor devices in the family is based on the standard xx75 functionality offered by a number of vendors. The inclusion of nonvolatile registers to permanently store device configuration settings adds flexibility. All family devices measure and monitor temperature to address a variety of thermal-monitoring requirements.
The sensors will find homes in consumer, industrial, computer and medical applications.
