Description
The Atmel® AT30TS750A 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 AT30TS750A 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.

FEATUREs
● Single 1.7V to 5.5V supply
