AVR 8-bit

When purchasing AVRs note…

  • The -10xx means 10MHz max speed, -16xx means 16MHz, etc.
  • However, the speed the chip can run at is proportional to the voltage, check the datasheet for the max speed at a given VCC (its near the end)
  • The -nnPx means DIP, -nnAx means TQFP and -nnMx means QFN
  • The -nnxU means RoHS, -nnxI is not RoHS
  • The V postfix means "Low voltage" generally 1.8V+
  • The P postfix is 'picopower' which is a different chip fabrication technology, thus Atmega168P is compatible with but slightly different than the Atmega168. P parts can run as low as 1.8V
