At present, in the microcontroller application market, still dominated by 8-bit microcontrollers and 32-bit microcontrollers. So why this market phenomenon, we must first understand the definition of 8-bit microcontroller and 32-bit microcontroller, in order to know the difference between the two.

8-bit microcontroller and 32-bit microcontroller difference

A, 8-bit, 32-bit microcontroller is what?

        How many bits of microcontroller, generally refers to the internal CPU processing data bus width, 8-bit microcontroller bus width of 8 bits, usually can only handle 8-bit data. A 32-bit microcontroller has a 32-bit bus width and can handle 32 bits of data. Simply put, "8-bit/32-bit" is the length of the data in the register involved in the operation.

Second, what is the difference between 8-bit and 32-bit microcontrollers?

        Compared with 32-bit microcontrollers, 8-bit microcontrollers have a natural advantage and a lot of room for growth, but they are more suitable for individual use in a product. In some small applications, the performance of 8-bit microcontrollers is sufficient, and the number of small applications is also very considerable. With the accelerated development of smart phones and tablet PCs, touch is gradually spreading to automotive electronics, medical, home appliances and other fields, and related applications will become more and more common. Touch is still on the rise, and 8 microcontrollers can fully meet this demand. Therefore, due to its simple and flexible application, safety and stability, cost advantages and other characteristics, 8 MCU will still expand with the growth of the overall MCU market.

        32-bit microcontrollers will become the mainstream of IoT applications, because in many cases, not only is there a need to achieve a shift from mechanisation to electromagnetization and intelligence, but also reliable connectivity, security and protection, and the implementation of these functions requires the involvement of 32-bit microcontrollers. In recent years, the share of 32-bit microcontroller products in the overall microcontroller market is also growing rapidly, but the real path to development is to find the value of product adhesion.

        Nowadays, when developing microcontroller solutions, more consideration is given to the integration and code reusability of 8-bit microcontroller and 32-bit microcontroller platforms, while customers also try to standardise their software within a platform to reduce software development costs and make it easy to design across high-end platforms, so the market for 8-bit microcontrollers and 32-bit microcontrollers is quite competitive.
