Top 5 Smallest Microcontrollers

Micro controllers takes important positions in all over electronics world, microcontroller gets more power, abilities and it rises day by day. Some applications like IoT (Internet of things), wearable electronics are pushing the limits and boundaries of microcontrollers.

In this Article we have listed top 5 smallest micro controller in the world, It help you to compare and give some ideas on the size of mircocontrollers. Here we have listed each microcontrollers with their bit size, package size and some important internal perpherals. each and every micro controllers has unique features and desired applications refer datasheet for more details.
