Could we blindly drop a ATMega168P in place of a ATMega168?
I would like to know if anyone has this kind of experience. Both ATMega168P are 20PU. Have you done or would you do this blindly? That is, imagine you have a product running on...

Looking at the end of a long cable on a LPT programmer
Hello Freaks, It's well-known that the problems with having a long cable on those cheap LPT programmers are due to the ringing on the SCK line, leading the AVR to see more clocks...

Strange RESET pin behaviour on AT90S2313
Hello Fellow Freaks, I've just assembled a very small board to be used as as generic controller "core" based on an AT90S2313. The circuit is very very simple as you can see in the...
