It was from a seller on eBay, they have a lot of bad feedback.
I tested my PICKit with a random micro i found on a board from a defunct ATX PSU and it recognised the chip straight away first time.
Im pretty sure i didn't damage the chip, I hand soldered the first one using a soldering iron and the second was flowed with hot air, both exactly the same result, the chip obviously connects but its type and memory locations are not correct.
I questioned the seller on eBay about the chip, they sent me a refund without any further response so i think i have my answer.
I have re ordered them again from a non reputable supplier, but I have no choice right now as they are out of stock at mouser and RS. Im honestly not surprised they are fakes, there are so many fakes of everything about right now its getting ridiculous.
