LX4F232H5QDA3 and LM4F232H5QD difference

German Alfaro1

Hi,

I've trying to get some  LM4F232H5QD parts for manufacture a prototype without any look. I want to ask you what is the difference between  LM4F232H5QD, LX4F232H5QDA3 and LX4F232H5QDB0,  can I expect the same functionality software/hardware and pinout use from the LM4F232H5QD?

Also any pointers where we can get any of those chips will be very appreciated, in a extreme case of not parts available it is possible to change with minimal effort to a Cortex M3 family? Please help

Thanks

German

    Hello,

    The part numbers that you have outlined are the same device but there are some differences.  I'll explain.

    LM4F232H5QD is a base part number.

    LX4F232H5QDA3 - the X that replaces the M indicates that this specific silicon is "experimental" and is not considered fully qualified for production use.  When a device is first released for sampling, evaluation, etc, you will typically see a character replacement with and X in the part number (TMX320, XMS430) or an additional X added (XAM3359).  The A3 indicates the specific silicon revision.

    LX4F232H5QDB0 - see above, the B0 indicates silicon revision.

    For differences, you would need to consult the device's silicon errata documentation.
