A microcontroller is a type of integrated circuit chip that uses ultra large scale integrated circuit technology to integrate data processing capabilities into the central processing unit (CPU), random access memory (RAM), read-only memory (ROM), and various types of I; O port and interrupt system, timer; A small and comprehensive computer system composed of functions such as timers (which may also include display driver circuits, pulse width modulation circuits, analog multiplexers, A; D converters, etc.) integrated onto a silicon wafer.

Small memory capacity
Due to integration limitations, the on-chip memory storage capacity is relatively small, with a general internal ROM of less than 8KB; Internal RAM: Within 256KB.

Easy to expand
The microcontroller is easy to expand and can add external memory, peripherals, etc. as needed.

High reliability
Microcontrollers have high reliability due to their low circuit complexity and high integration, which reduces the number of connections on the circuit board and thus reduces the failure rate.

Strong control function
The microcontroller has powerful control functions and can achieve various control tasks, such as timing, counting, PWM, etc.

Easy to develop
The development tools and environment for microcontrollers are relatively mature and easy to develop.
