Important Processors in Embedded Systems

  • 8051 family (Intel/MCS-51): 8-bit control, cheap, widespread for appliances.
  • AVR (ATmega): RISC, Arduino, low-power.
  • PIC (Microchip): Wide range, industrial.
  • ARM (Cortex-M0/M3/M4): 32-bit, high-performance, phones, RTOS.
  • MSP430 (TI): Ultra-low-power for battery/IoT.
  • RISC-V: Open-source, emerging.
  • DSPs (TI C2000): Signal processing.
  • SoCs (ESP32): WiFi/BT + MCU.

Selection depends on performance, power, cost, peripherals, tool chain.
