I would like to know what is the temperature accuracy you can get with this microcontroller based TEC temperature controller? And also can you please tell me which microcontroller have you used in that  low power TEC driver reference design?

    With this experiment we were able to control the temperature (steady state) at an accuracy of 0.2°C. The microcontroller we have used was MSP430F5529.
    Basically accuracy depends on the accuracy of the temperature measurement and the implementation of the control loop. Both was not the main focus of this design. It just has been done to demonstrate the feasibility of controlling the temperature in such a simple power configuration. The implementation of the control loop did not demand significant resources, so the requirements for the microcontroller were not so challenging.
