The AT30TS74 device combines a high-precision digital temperature sensor, programmable 2 high and low temperature alarms, and a 2-Wire I C and SMBus (System Management Bus) compatible serial interface into a single compact package. The temperature sensor can measure temperatures over the full -55C to +125 C temperature range and has a maximum accuracy of 2.0 C from -20 C to +100C. The result of the digitized temperature measurements are stored in one of the AT30TS74 internal registers, which is readable at any time through the device s serial interface. The AT30TS74 utilizes flexible, user-programmable internal registers to configure the temperature sensor s performance and response to high and low temperature conditions. A dedicated alarm output activates if the temperature measurement exceeds the user-defined temperature and fault count limits. To reduce current consumption and save power, the AT30TS74 features a Shutdown mode which turns off all internal circuitry except for the internal Power-On Reset (POR) and serial interface circuits. The AT30TS74 is factory-calibrated and requires no external components to measure temperature. With its flexibility and high-degree of accuracy, the AT30TS74 is ideal for extended temperature measurements in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. 2 AT30TS74 DATASHEET Atmel-Advance Information-DTS-AT30TS74-Datasheet 022017
