how do chips go bad?
Chips run off of smoke. The smoke is carefully inserted during the manufacturing process. If you let the smoke out, the chip no longer functions.

Atmel 40 Mhz microcontroller in the works or already here?
Quote:I have searching for an Atmel 40Mhz uC to replace a PIC18F4xxx uC, I take it there isn't such a comparable Atmel device out on the market yet? If not, any talks about such a...

It's been several days since the OP has posted any progress, so I fear they may be stuck. With that in mind, I have attached a document that may give the OP some direction, and...

7805 So hot!
First, is your 12V power supply an unregulated "wall wart" ? If it is, then it's output might be considerably higher than 12V. Especially if it's rated for 1amp, and you are only...

PWM....without PWM?????
At a frequency of 1/30HZ, I think a software PWM is your only option (at least on an AVR). You can setup a timer for a 1mS compare. On each timer compare interrupt, you increment...

flash (writable) variable
Before you can get a good answer to your questions, I have a few questions for you. What type of "variables" to you plan on writing to flash ? Why can't these be written to EEPROM...
