TDC1000-C2000EVM: Differences Between TDC1000-TDC7200 and TDC1000-C2000

Part Number: TDC1000-C2000EVM
Other Parts Discussed in Thread: TDC1000, , TDC7200

I'm looking to use a transducer to measure liquid levels inside a sealed container. I'm having difficulty understanding the differences between the two of these development boards. 

I presume I'm looking to purchase the TDC1000-C2000 but was wondering if someone could clarify the major differences as far as applications for the TDC720x and TDC10xx devices (and in turn these two development boards). Thanks!

    Hello Tyler,

    The TDC1000 is the ultrasonic AFE that interfaces with the ultrasonic transducers to transmit and receive the ranging signals. It ouputs a start and stop signal that will be measured by another device. In the case of the TDC1000-TDC7200EVM, that time is measured by the TDC7200 (or the onboard MSP430 microcontroller-- this is selectable in the GUI). On the TDC1000-C2000EVM the C2000 microprocessor handles the time of flight measurement. The TDC7200 allows for more precise time measurement.

    The main reason for the existence TDC1000-C2000EVM is to demonstrate a solution for automotive applications (the C2000 has automotive qualifications, while the TDC7200 does not). For non-automotive applications, I recommend the TDC1000-TDC7200EVM because even if the precision of the TDC7200 is not needed, the TDC1000 can still be evaluated by using the MSP430 to measure the TOF.

    Regards,
