Hi, I was making some tests with my jaguar 0.7 and made a mistake leaving alone a +12v wire that touch the board and the MCU is dead :(:(

where do you recommend me to buy a replacement? same reference or there are more equivalent?

Sorry to hear about that, but welcome to the small club (4 people that I know) of those who have managed to killed a processor.

You want to replace it with the same Freescale/NXP MC9S12XDP512MAL processor.
The suffix MAL means: M = -40C to 125C operating temperature, the L = 112 pin LQFP footprint.

You want to stay away from the CAL (-40C to 85C) and VAL (-40C to 105C) suffix processors as they have a narrower operating temperature range.

Here is a link as a reference:

You may find the processors in the UK or Europe at a better price, just make sure they are genuine Freescale or NXP parts.
Be wary of processors from eBay or from a Chinese websites as they may not be genuine processors!!!
