MCU is short for Microcontroller Unit, Chinese called microcontroller, commonly known as microcontroller, is the CPU frequency and specifications to do appropriate reduction, and memory, counter, USB, A\/D conversion, UART, PLC, DMA and other peripheral interfaces, even LCD driver circuit are integrated on a single chip. Form a chip-level computer to do different combination controls for different applications, such as mobile phones, PC peripherals, remote controls, to automotive electronics, industrial stepper motors, robot arm control, etc., the MCU can be seen.

Classification and application of single chip microcomputer
According to its memory type, MCU can be divided into two types: on-chip ROM type and on-chip ROM type. For chips without on-chip ROM type, EPROM must be connected to the external application (typically 8031); The chip with on-chip ROM type is divided into on-chip EPROM type (typical chip is 87C51), MASK on-chip mask ROM type (typical chip is 8051), and on-chip Flash type (typical chip is 89C51).

According to the use can be divided into general type and special type; According to the width of the data bus and the length of the data bytes that can be processed at one time, it can be divided into 8, 16 and 32 bit MCUS.

At present, the domestic MCU application market is the most widely used in the consumer electronics field, followed by the industrial field, and the automotive electronics market. Consumer electronics include home appliances, televisions, game consoles and audio and video systems. Industrial sectors include smart homes, automation, medical applications and new energy generation and distribution. The automotive field includes automotive powertrain and safety control systems.
Hello, mcu chip belongs to the chip level chip. Because the mcu is called a microcontroller, the internal memory and storage in addition to the central processor can be directly added to simple peripheral devices (such as simple circuit components such as resistors and capacitors) to run code. For example, the autonomous driving technology used in the future of automobiles is used in this chip, so the mcu belongs to the chip level chip. Hope it helps.
