What AVR Should I Get?


I'm looking at getting a small (4-6 IO) AVR chip for a new project.

The chip needs to have both UART and I2C (Master) capabilities, as well as being Arduino compatible.

So far, I've looked into the ATTiny13 and ATTiny 25/45/85 chips, but couldn't really find much...

Of couse, as many Arduino enthusiasts, I have a few ATMega328s hanging around that I suppose I could put to work...

I plan on hooking it up to a SSD1306 driven OLED via I2C, and an ESP8266 via UART.

Would anyone be able to recommend any chips? Would any of the chips listed above work for my situation?

Any help would be great!

The t13 is ancient, and mostly TOO tiny.
