I don't believe you can reliably distinguish among many of these parts.
I've had parts stamped with a number on them, but it looks like it had
remnants of other, probably non-working, peripherals from another.
Just poking at some peripheral locations to determine processor
type isn't likely to always be accurate.
I don't think we should be writing any code that relies on the proper
identification of the parts. When building the code for a real product,
you always configure specifically for it to reduce code size and run
time
start up. As a development engineer, you should know the configuration
you are using as well. The only difference is in the peripherals
supported,
so just configure what you want to use.
Thanks.
