Description
The Atmel® AT30TS750 is a complete, precise temperature monitoring device designed for use in a variety of applications that require the measuring of local temperatures as an integral part of the systems function and/or reliability. The AT30TS750 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.
