CCF430 family Vs Launchpad

Other Parts Discussed in Thread: CC430F6137

Hi all, 

In the long and harsh run to the election of the perfect component for an specific aplication i´ve been looking for an adc conveter of at least 12 bits. After look for them in distributors like farnell, digikey or mouser i found that they are quiet expensive (i call expensive a price over 5 euros what is aproximately 6.5 dollars) so i decided to look for a MSP with the an ADC of over 12 bits integrated.There´s no one that fits the launchpad socket and that has an ADC over 10 bits.

So if i try to program any other MCU that has the Spy-wire interface with the launchpad, will i be succesful? For example, if i try to program the CC430F6137?

Thanks to all, and long life to MSP430!

    Try to make your own PCB, its easy, or you can buy ready adapter with external pins and intall CC430F6137 on it. I using this family and its standard JTAG and Spy by wire programinng interface. If you hava standard TI dubbuger e.g. MSP-FET430UIF it surly can be programed. I hope I help

    yes, sure you helped and thanks for the reply! I ´m thinking to build a PCB to work with the CCF430F617, so i´ll try ;). thanks again .

    Hi Alvaro,

    first of all you can build up a custom board and breakout the pins for SBW (Spy-Bi-Wire) protocol and connect it to the launchpad. But remember this is a high speed serial protocol, so use wires as short as possible and of equal length. Also keep in mind, that there is a maximum capacitance allowed from RST pin to GND (no more than 2.2nF if I'm right, better lower for safe connection).

    Apart from that, do you really need the CC430 series? These come with an integrated radio for wireless communication - if you build a board an antennas for these it becomes much more complicated and it may be difficult to meet regulatory requirements, even in sub-GHz.

    MSP430F5324 - has also a 12bit SAR ADC

    From the MSP-EXP430G2 LaunchPad Experimenter Board User's Guide:

    The LaunchPad experimenter board is capable of programming the eZ430-RF2500T target boards, the eZ430-Chronos watch module or the eZ430-F2012T/F2013T target boards.

    Given that the eZ430-Chronos watch module uses a CC430F6137, the firmware in the launchpad should support programming your device.

    (From the documentation not sure if the programming firmware in the launchpad supports any other CC430 devices, or if it only supports the specific CC430F6137 used in the eZ430-Chronos)
