MCU, or Microcontroller Unit, is commonly known as a single-chip microcomputer. It integrates the CPU, RAM, ROM, timers, and various I/O interfaces onto a single chip, forming a compact computer system that can be programmed for different applications. These devices are widely used in consumer electronics, automotive systems, industrial automation, and more. Today, we’ll take a closer look at some of the top MCU companies in China.
