Re: Code protection

2004-05-05 by bobtransformer

The reason I am interested in looking at other parts are because of 
Atmels bad silicon on the ATmega32,64, and 128 parts and Atmels poor 
response to customers problems.   The parts don't work at 16 MHz and 
sometimes down to even 10 or 12 MHz when warm.

Thanks,
bob
