Request for LM4FSXAH5BB data sheet

Hello,

We have got request from our customer to implement the programming support. Unfortunately we can't find out the data shett of this chip, so we aren't sure whether such device really exits.

So, could you let me know if this device is real and could you provide the data sheet?

Best regards,

Frantisek

That part number points to a "special" MCU - not one offered (usually) to the public.

Closer view of the chip's marking should reveal "LX4F...." there were "no" LM4F devices produced...

As those devices are no longer produced - your quest seems confined to just those parts the client may have - with "no" prospect of "further device arrivals."

Switch-over to the most compatible, "TM4C123" seems your best option. (client's "losing the data sheet" (for so "special" a chip) - speaks volumes ... none good...)

I don't recognize that part number but I will keep looking. This post lists LM4 parts I do know:

This is not an option, customer asked to implement the programming support for exact chip.
