I'm looking to build a pretty basic project that relies on several submodules that use I2C for communication. I'm trying to find the smallest, cheapest AVR device that supports I2C. I know the 328P has a built in I2C interface, but I really don't need the 20 something other pins. Can anyone point me towards something more like an ATtiny that has a built in I2C interface?
My goal is the smallest, cheapest AVR without relying on software IC2 implementation.
