Can you recommend a MCU with 16+ bit ADC that is supported by the Launchpad?

Hey everyone,

 

Looking at the compatible devices page here, there only appears to be 10 bit ADC's.  Does anyone know if there are any MCU's that can be programmed with the launchpad that have 16-24 bit ADC's?  If not, are there any other ways to get 16 bit resolution?  

Thanks!

    Joseph,

    The MSP430 has a different options for getting ADC resolutions of > 16 bits. The MSP430AFE devices have 24 bits of resolution, and some of the MSP430F4XXX familys have 16 bits ADCs.

    You may want to obtain a MSP-FET430UIF tool, as this supports both JTAG and SBW.  The launchpad supports SBW, but not all the devices support SBW programming/debugging.

    If you click on the MCU selecter guide, you can filter by ADC resolution of >=16 bits, and it will show you the devices that are available.

    Here is a link to the tool:

    Thanks Jason,

    It looks like there are two options with >16 bits ADC and DIP, the MSP430F2013  being the one with larger memory.  I also looked some with TSSOP, and it looks like the msp430afe253 would be a nice option with greater memory and resolution

    I plan to get the afe253 and a breakout adapter, then wire to the jumper pins on the launchpad for programming.  According to the datasheets, both MCU's support SBW.  Is there any reason this wouldn't work?

    In theory it should work. The only thing I am not certain of is if the launchap has hooks in it to only support Value line parts. I have not tried to program other 430's with it in the manner that you are speaking of.

    There is an adapter board that you can get for the AFE devices. You can get it also as a package with a FET tool which you would definatley be good to go!
