Tiny 45/85 alternative.

Hi All

I was wondering if there is an alternative to using the Tiny 45 or 85. I with a few more pins.

Thanks

@xl97, I cannot see your image

@kculm, what about ATtiny2313?
2K flash
20Mhz
20 pins
18 I/O pins (17 if you use PA2 as a reset pin)

Ok Guys,

I picked up some 85 just to start playing with. I have run though all the Tuts I can find but I am having no luck programming it. I keep get errors what I get the part Burn Boot loader. ( I will post the Errors once I get it set back up.

I am using Arduino 1.0.3 and AtTiny85 20MHz.

Anyone know of any Issues with that config.

Thanks

This page* says that Arduino 1.0.2 doesn't work with the ATtiny85, or at least not with some particular Arduino ATtiny interface drivers. Maybe that was fixed in 1.0.3 or doesn't relate to the Arduino software you're working with at all, but perhaps you need to back up to 1.0.1, like they suggest? Just an idea, I'm only using ATmega328's at the moment myself.

A higher pin count alternative to the 25/45/85 series is the 84 a 14 pin chip.
I am using 85's with 1.0.2 though I am using cores from the Google core site.
I will post a link when I get back home and to my computer. Also try burning the 1 MHz boot loader first....then selecting another.....I read somewhere it was a work around.

These cores work for me with arduino 1.0.2.
