AT30TS74 [PRELIMINARY DATASHEET]

Atmel-8897D-DTS-AT30TS74-Datasheet_102014

Description

The Atmel® AT30TS74 is a complete, precise temperature monitoring device designed for use in a variety of

applications which require the measuring of local temperatures as an integral part of the system's function

and/or reliability. The AT30TS74 device combines a high-precision digital temperature sensor, programmable

high and low temperature alarms, and a 2-Wire I2C and SMBus (System Management Bus) compatible serial

interface into a single compact package.

The temperature sensor can measure temperatures over the full -55

C to +125C temperature range and has a

maximum accuracy of ±2.0

C from -20C to +100C. 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.
