    пЈ§ 8-pad Very Very Thin DFN (2 x 3 x 0.8mm) Description
    The AtmelВ® 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 -20В°C to +125В°C to a digital word and provides an
    accuracy of В±1В°C (max.) in the temperature range +75В°C to +95В°C. The temperature
    sensor continuously monitors temperature and updates data in the temperature
    register at least 8 times per second.
    The AT30TS00 supports the industry standard 2-wire I2C/ SMBus serial Interface to
    include a time out feature to help prevent system lock-ups.
    The AT30TS00 has flexible user programmable internal registers to configure the
    temperature sensor performance and response to over temperature conditions. The
    device contains programmable high, low, and critical temperature limits. A dedicated ...
