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 …
