It doesn't make me nervous that it's a 40-pin device. It makes me unhappy that it doesn't fit. It needs to be a 20-pin device, because there's a 20-pin DIP socket into which it has to fit. Oh, and what's the probability that a 20-pin '51 would fit into that socket, I mean, pin to pin? What space have you available? You'll need to make some conversion board anyway, and I doubt you can make it as small as a DIP20 too easily. Not to talk about crystal and stuff a typical '51 would need. Or, if you go for the LPC9xx things, you'll then cope with 5V incompatibility. How many pieces are we talking about? Isn't it worth to try to hunt up the original part, whatever it would cost? Isn't it by chance this one? JW |
