Industry Standard Green (Pb/Halide-free/RoHS Compliant) Package Options  8-pad Very Very Thin DFN (2 x 3 x 0.8mm) Description The Atmel® AT30TS00 combines a temperature sensor, programmable overtemperature alarms, and a 2-wire I2C/SMBus compatible serial interface into single compact packages specifically designed for DRAM memory module applications. However, the AT30TS00 is ideal for many other applications. The AT30TS00 converts its die temperature into digital values using internal analog-to-digital converters (ADCs). The result of the conversion is held in a temperature register and is readable at any time through the serial interface. The temperature sensor converts temperatures from -20°C to +125°C to a digital word and provides an accuracy of ±1°C (max.) in the temperature range +75°C to +95°C. The...
