Every Microcontroller Architecture in 40 Seconds

Added: 2026-05-26

[00:00:00]Every microcontroller architecture in 40 seconds. AVR is simple and easy to work with. It powers classic boards like the Arduino Uno. 8051 is one of the oldest architectures still in use. Even modern chips like the EFM8 Laser Bee still use it because it's cheap, compact, and reliable. ARM Cortex-M dominates modern embedded systems. Boards like the Raspberry Pi Pico and STM32 Black Pill use ARM cores for much higher [music] performance and better peripherals.

[00:00:28]High-end boards like the Teensy 4.1 use chips like the i.MX RT 1060 running at 600 MHz. The ESP32 uses Tensilica Xtensa cores designed for high-performance wireless and real-time processing.

[00:00:42]RISC-V is growing fast because it's open source and fully customizable. Comment your favorite microcontroller.
