this is a smaller one of the avr series, but has anyone downloaded a bootloader for these MCUs. I would greatly appreciate it if someone has made one, or knows a source for these MCUs with the bootloader in them already

Hi tech20,

The ATtiny series doesn't have bootloader support at all -- you have to program the chips directly via an ISP programmer, such as our parallel port hack (if your computer has a parallel port), or something like the Atmel AVRISP-MKII. Hope that helps!

Hi Mike,

What's the smallest MCU from ATmel that supports your great bootloader ?! Thanks !

Hi Alexguiral,

I'm not too familiar with the entire AVR line but just looking through their website I think the only smaller chip that is still loadable with a similar bootloder is the ATmega48, which is basically the Atmega168's little brother. It only has 4KB of Flash memory and 512 bytes of RAM.
