8 bit Vs 16 bit Microcontroller | Difference | Comparison

The main difference between an 8-bit and 16-bit microcontroller is that an 8-bit microcontroller can only process 8-bit data and 8-bit program memory. A 16-bit microcontroller can manage data and program memory of the same size. This differentiates them in terms of efficiency and functionality.

Microcontroller   

A microcontroller is a CPU-equipped semiconductor. It effectively provides something for the CPU to read from. In the absence of a microcontroller, a CPU is virtually useless. As a result, a microcontroller with 8 bits can read 8 bits of data. A 16-bit microcontroller has 16 bits, a 32-bit microcontroller has 32 bits, and so on.

8-bit microcontroller

The 8-bit microcontroller has an 8-bit data word length. word length or word size refers to the number of bits that a microprocessor can process at once. 8-bit microcontrollers are a necessary component of embedded systems. They are widely employed in industrial applications and are increasingly being used in industrial applications and are increasingly used in household appliances. 

16-bit microcontroller

A 16-bit microcontroller is one that can handle data with 16 bits, allowing it to manage a larger amount of data and computations at once. It also uses less power and operates at a quicker clock speed than an 8-bit microcontroller. It is presently the most popular microcontroller. Instructions, data, and addresses are all included. 16-bit controllers are commonly found in high-end equipment and electrical gadgets.
