There are significant differences between microcontroller chips and ordinary chips.
< br >
1. Different functions: The single chip microcomputer chip is an integrated circuit chip, which integrates CPU, RAM, ROM, a variety of I\/O and interrupt systems into a silicon chip through very large scale integrated circuit technology to form a microcomputer system. Ordinary chips, on the other hand, are relatively one-dimensional, often containing only the basic processor and memory to implement a specific function or application.
2. Different integration: the integration of single-chip chip is significantly higher than that of ordinary chip. The MCU chip integrates all the main parts of the computer system, including CPU, memory and I\/O interface, forming a complete computer system. Ordinary chips, on the other hand, usually contain only the basic processor and memory for a specific function.
3. Different programmability: The single chip microcomputer chip has a certain degree of programmability, and can achieve specific functions by writing simple control programs. The ordinary chip is usually not programmable, its function has been set at the factory, relatively single.
4. Different reliability: The reliability of the MCU chip is high, because it is integrated with a number of functional modules, each module is relatively independent, so even if one module fails, it will not affect the normal work of other modules. The functions of ordinary chips are relatively single, and once a failure occurs, it may affect the operation of the entire system.
5. Application range is different: single-chip chip is mainly used in micro-control circuits, such as smart home, industrial control, automotive electronics and other fields. Ordinary chips are more commonly used to implement specific functions or applications, such as audio processing, image recognition, and so on.

In short, there are obvious differences between single-chip chip and ordinary chip in function, integration, programmability, reliability and application range. According to different application requirements, the appropriate chip type can be selected to achieve the expected function.
Including the model, processor architecture, memory capacity, the number and type of peripheral interfaces.
1. Model: Different microcontroller chips have different models, representing different series and characteristics.
For example, STM32 series and Arduino series of microcontroller chips have different models and functional characteristics. 2. Processor architecture: MCU chips can adopt different processor architectures, such as chips based on ARM architecture or AVR architecture.
The characteristics and performance of different processor architectures will also vary.
3. Memory capacity: There are also differences in the memory capacity of single-chip chips, including flash memory, RAM, etc.
Different applications require different memory capacities to store code and data. 4. Number and type of peripheral interfaces: The number and type of peripheral interfaces provided by the MCU chip may also be different.
Some chips may provide more general input output pins (GPIOs), while others may provide more communication interfaces such as UART, SPI, I2C, etc. To sum up, it is mainly reflected in the model, processor architecture, memory capacity, and the number and type of peripheral interfaces.
These differences make it more important to choose the appropriate microcontroller chip in different application scenarios.
