TDC1000-TDC200EVM and TDC1000-TDC7200EVM differences

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

1) What are the main differences between the processors in the TDC1000-TDC200EVM and the TDC1000-TDC7200EVM and what are the implications of those differences? (what situation does it excel at?)

2) Can both the MSP430F5528 and the C2000 be programmed in C or C++?

3) The addition of the TDC7200 with the TDC1000 MSP430 means more accurate timing, but with and without the TDC7200, what and how much does that translate in terms additional measurement accuracy?

4) For battery operated and low power requirements, it seems like the TDC 1000-TDC7200 is the best choice?

    1) TDC1000-C2000EVM is recommended for automotive grade applications. TDC7200 is not automotive grade. C2000 has a high resolution timer that can perform time measurement but it's resolution is 500ps compared to 55ps of TDC7200. C2000 is a DSP so well suited for signal processing applications.

    2) Yes, you can program both devices in C.

    3) TDC7200 measurement resolution is 55ps. If you MSP430 timer, best resolution is about 42ns (from 24MHz system clock).

    4) Yes, compared to C2000, TDC1000 + TDC7200 would give the best low power number.

    Thanks,
