3.9.3 Temperature Sensor
The Atmel AT30TS75 temperature sensor converts temperatures from -40°C to +125°C to a digital word and
provides a typical accuracy of ±0.5°C over the operating temperature range of 0°C to +85°C. The device is factory
calibrated and requires no external components to help provide a cost effective solution. To reduce current
consumption and save power, the AT30TS75 features a shutdown mode that turns off all internal circuitry except
for the internal power-on reset and serial interface circuits. In addition, the device features a power saving one-
shot mode that allows the device to make a temperature measurement, update the temperature register and then
return to shutdown mode.
Device slave address byte: 0x48.
