What is the difference between 8 bit and 32 bit microcontroller?

Question

Accepted Answer

8-bit microcontrollers have smaller data and address buses, limited memory, and lower processing power compared to 32-bit microcontrollers.

8-bit microcontrollers have a data bus width of 8 bits, while 32-bit microcontrollers have a data bus width of 32 bits.
8-bit microcontrollers typically have limited memory capacity, while 32-bit microcontrollers can support larger memory sizes.
32-bit microcontrollers have a higher processing power and can execute instructions faster than 8-bit microcontrollers.
8-bit microcontrollers are commonly used in simple applications with low processing requirements, while 32-bit microcontrollers are used in more complex applications.
Examples of 8-bit microcontrollers include the Atmel AVR series, while examples of 32-bit microcontrollers include the ARM Cortex-M series.

Accepted Answer

8 bit microcontroller work on 8 bit data register while 32 bit microcontroller work on 32 bit register.
