Smallest microcontroller? I am looking for a microcontroller that is small (like a attiny10) which is the smallest one I could find.
Requirements I need: analogRead on 1 pin, 7 pins for analogWrite to micro leds so in total 10 pins (ground, power, analogRead, analogWrite). It's circuitry has to be basic no adding extra things like a crystal oscillator etc.. This will allow me to send a certain code to the recieving pin and then the microcontroller decide which led to turn on.
I don't know whether it's really the smallest you can find but... The
ATtiny84 has an ADC, more digital pins than you need, and is
available in 3 mm packages (UFBGA and VQFN). There is also an
Arduino-compatible core available for it.
