One limitation should be obvious, which is the limitation on arithmetic operations. However, there are other differences between 8-bit and 32-bit microcontrollers that span beyond arithmetic operations. In general, this means that a 32-bit can handle quadruple the amount of data, making it technically more data efficient. They have 32-bit arithmetic logic units, registers, and bus width. So, what is an 8-bit microcontroller? A 32-bit microcontroller can theoretically handle numbers reaching 2^32. An 8-bit microcontroller has limited addressing, but some 8-bit microcontrollers use paging, where the contents of a page register determine which onboard memory bank to use. The number of bits used by an MCU (sometimes called bit depth or data width) tells you the size of the registers (8 bits per register), the number of memory addresses (only 2^8 = 256 addresses), and the largest numbers they can process (again, 2^8 = 256 integers, or integers 0 through 255). Strictly speaking, an 8-bit microcontroller processes 8-bits of data at any particular time. 8-bit vs 32-bit MCU: Microcontroller Basics To make the right choice, however, it’s important to understand the fundamental differences between the 8-bit vs 32-bit MCU. They’re not too different in terms of cost, and one is more powerful than the other. Thankfully, I’m more decisive when choosing between 8-bit vs 32-bit microcontroller devices for my hardware design. Torn between buying a new laptop or upgrading my tablet to an iPad Pro, I end up purchasing both and getting an endless lectures from my fiancé. I have very bad shopping habits when it comes to electronic gadgets.
