Atmel Digital Temperature Sensors
World’s Most Versatile Temperature Sensing Solutions
Atmel Digital Temperature Sensors
Accurate, Complete, and Easy to Use
Atmel Digital Temperature Sensor products are complete and easy-to-use solutions that address the ever-growing need
for temperature sensing. Atmel offers these solutions as drop-in replacements for industry-standard LM75-type devices
as well as JEDEC-standard compliant solutions for DDR3 and DDR4 DIMM modules. Atmel Digital Temperature Sensors also
provide enhanced features, such as integrated EEPROM and nonvolatile registers, to reduce BOM cost, improve system
flexibility and product reliability, and enhance application safety.
In terms of performance, Digital Temperature Sensors offer excellent accuracy and a precise, fully calibrated digital temp-
erature reading in degrees celsius. Digital Temperature Sensors eliminate the need for additional components, such as an
A/D converter, within the application, and there is no need to calibrate components or the system at specific reference
temperatures as required when using thermistors. Atmel Digital Temperature Sensors take care of it all, enabling the critical
system temperature monitoring function to be simplified.
All devices are available in 8-lead packages and support SMBus Time-out
