What chip does mcu chip refer to?

MCU (micro control unit) is a microprocessor chip designed for control processing of specific applications. It appropriately reduces the frequency and specifications of the central processing unit (CPU) and combines memory and counters. , USB, A/D conversion, UART, PLC, DMA and other peripheral interfaces, and even LCD driver circuits are integrated on a single chip to form a chip-level computer that can perform different combinations of controls for different applications.

Microcontroller Unit (MCU), also known as Single Chip Microcomputer or single chip microcomputer, is a microprocessor chip designed for control processing of specific applications. Its operating frequency (1MHz to 200 MHz) and power consumption are generally lower than those of PC and mobile phone CPU/MPU. Today's MCUs are all system-on-chip (SoC), integrating a variety of functional modules and interfaces on a single chip, including memory, I/O ports, clocks, A/D conversion, PWM, etc., as well as SPI, I2C, ISP, etc. Data transmission interface.

MCU appropriately reduces the frequency and specifications of the Central Processing Unit (CPU), and combines memory, counter (Timer), USB, A/D conversion, UART, PLC, Peripheral interfaces such as DMA and even LCD driver circuits are integrated on a single chip to form a chip-level computer that can perform different combinations of controls for different applications. MCUs can be seen in applications such as mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepper motors, and robot arm control.

According to the number of bits, MCU can be divided into 4-bit, 8-bit, 16-bit, 32-bit and 64-bit microprocessors. Now 32-bit MCU has become the mainstream , is gradually replacing the applications and markets dominated by 8/16-bit MCUs in the past. If divided according to instruction set architecture (ISA), MCU types include 8051, Arm, MIPS, RISC-V, POWER and other microprocessors. MCUs based on the Arm Cortex-M series core IP have become the mainstream of the 32-bit MCU market. In recent years, open source RISC-V microprocessors have also become popular, especially in the emerging field of Internet of Things.
