As electronic technology advances rapidly, the complexity and integration of electronic circuits continue to increase, demanding higher performance and functionality from control units. Microcontrollers (MCUs), as highly integrated microcomputer systems, have become indispensable core components in modern electronic circuits due to their powerful logic control capabilities, data processing capabilities, and rich peripheral interfaces.
Microcontrollers integrate components including a CPU, memory (Flash/RAM/EEPROM), input/output interfaces (I/O), and various peripheral modules (ADC, PWM, UART, etc.). Unlike general-purpose microprocessors (such as computer CPUs), MCUs are specifically designed for real-time control and low-power embedded applications and are widely used in smart hardware, automation equipment, and electronic instruments.
