I use to use the MC9S12DG128BCPV on a board that must operate at -32C, which it did, no problem.
Now that the leaded BCPV is no longer available, I have switched to the Pb free CPVE version. My first two boards now both fail at -32C and it appears that the micro is not running.
I still have more tests to do to confirm this, but are there any known issues with the Pb free CPVE version at extreme cold temperatures? It's operating spec is -40C.
Thanks for any help.
