Why 8-Bit Microcontrollers Are Still Relevant

In recent years, with the gradual maturity of processes and IP, 32-bit MCUs have grown rapidly, to the point where 16-bit MCUs are almost skipped. Nowadays, when talking about embedded MCUs, it is either 8-bit or 32-bit, with very few 16-bit MCU product models available. So, what about the situation with 8-bit MCUs? Many embedded … Read more
