AT30TS/TSE75x Devices
The Atmel AT30TS/TSE75x Digital Temperature Sensor Family comprises five high-precision devices based on the industry-
standard LM75 functionality. These devices offer designers a choice of nonvolatile registers and serial EEPROM for optimal
system reliability and increased integration.
The Atmel AT30TS/TSE75x Digital Temperature Sensor Family is a complete, fully factory-calibrated, real-time temperature
monitoring solution that operates over the -55°C to +125°C temperature range. The devices output digitized temperature
data via a standard I
2
C/SMBus-compatible serial interface, eliminating the need for any external components such as A/D
converters and data post-processing.
Feature Benefit Devices
