The ATmega328 an upgrade for the Arduino.
« on: January 07, 2009, 01:39:29 AM »
Would any of these work as a drop-in replacement for the ATmega128 in the arduino? http://www.stkcheck.com/evs/atmel/atmelheader2.asp?mfg=atmel&part=ATmega328P

Yeap. You just need an ISP hardware programmer to upload a 328P compatible bootloader . . . not sure if Arduino supplies one yet or not . . .

Otherwise, you can use my 328P bootloader on my $50 robot page instead.

IS there a difference between them? What do the numbers at the end mean?

Just look at the datasheets of each for comparison. They are pin compatible, just the later versions tend to be better like more memory and such.

The P at the end means its a low power version to save you ~15 mAh.

Has anyone found an ATMega328 supplier in the UK yet?

Farnell, RS, Rapide etc don't seem to supply to it yet. Appreciate I could it buy it in from abroad but would need to buy loads of them to make it worthwhile.

The standard arduino uses a ATmega168 20PU the drop in replacement is a ATmega328 20PU.  The bootloader is now part of the arduino software.  You can also use the bootloader from ladyada.  To burn the bootloader yourself you must have a hardware programmer.
