General description

The AS6204 is a complete digital sensor system, designed for the needs of high-performance consumer electronics. It is based on the well-proven AS6200 design, but with additional I²C addresses to serve complex design needs. This is especially useful in the prototyping phase of a product where several heat sensitive areas might need monitoring but without needing to reserve additional systems application processor resources. The AS6204 is a fully calibrated and linearized sensor system that is easy to integrate in any digital system. It provides a resolution of 12 bit over the wide temperature range
from -40°C to 125°C. The integrated alarm functionality enables micro-controller wake-up calls on defined temperature thresholds. An internal voltage regulator allows stable accuracy independent of the supply voltage between 1.8V to 3.6V. For powersensitive applications, the device can enter a low-power wait mode with 0.1μA current consumption.

This product suits for the following applications:

  • Laptops
  • Tablets
  • Solid State Disks
  • Industrial Automation

Temperature Sensor

The AS6204 is our highly precise digital temperature sensor which is mainly targeted towards consumer applications like laptops, cameras, tablets.

It features additional I2C addresses, which enables temperature monitoring on four different spots while using only one I2C bus.

In our demo we have a benchmark video running, while monitoring the temperature of RAM, RAM controller, SSD and graphic controller on the mainboard.
