Latest revision as of 19:55, 22 April 2024

The following is a rough guide, the reality is considerably more complicated.

Class Manufacturer Architecture Clock Wikipedia Notes
AVR Microchip (was Atmel) 8-bit AVR 1.6 to 32 MHz AVR microcontrollers ATmega328, ATtiny
PIC Microchip 8-bit to 32-bit PIC 0 to 200 MHz PIC microcontrollers
STM32 ST Micro 32-bit ARM Cortex-M0+ 0 to 48 MHz STM32 compatible: APM32 by Geehy Semiconductor
SAM Microchip (was Atmel) 32-bit ARM Cortex-M0+ 0 to 48 MHz Atmel ARM-based processors e.g. ATSAMD21G18
RP2040 Raspberry Pi 32-bit ARM Cortex-M0+ 0 to 48 MHz RP2040 Raspberry Pi Pico
ESP32 Espressif Systems 32-bit Xtensa LX6 / RISC-V 160 or 240 MHz ESP32 replaces ESP8266; integrated Wi-Fi and dual-mode Bluetooth
MSP430 Texas Instruments 16-bit MSP430 0 to 25 MHz TI MSP430 TI range
nRF Nordic Semiconductor 32-bit ARM Cortex 16 to 70 MHz Nordic Semiconductor e.g. nRF51, nRF52, nRF53, nRF91; nRF52833 used in the BBC µBits
