The MCU chip refers to the Microcontroller Unit (Microcontroller Unit; MCU), also known as a microcontroller or single-chip microcomputer. It appropriately reduces the frequency and specifications of the central processing unit and integrates memory, counters, USB, A/D conversion, UART, PLC, DMA, and other peripheral interfaces, even the LCD driver circuit, into a single chip, forming … Read more
Introduction: This article introduces the MCU chips in four domains: body, chassis, power, and cockpit, from four dimensions: working requirements, performance requirements, industry landscape, and industry barriers. It also organizes the application status of domestic MCU chips for reference by practitioners. 1. Introduction to Control Chips The control chip mainly refers to the MCU (Microcontroller … Read more
Abstract：We encounter many operating systems, such as Windows, Android, iOS, and Linux, which are all types of operating systems. Microcontrollers also have their own operating systems, known as real-time operating systems. So what are the differences between these real-time operating systems and the systems we use? The operating systems we commonly use are actually non-real-time … Read more
IAP Let’s start with the most relevant topic mentioned above, IAP (In Application Programming). As the name suggests, it means that user code can erase and program the flash memory area. Different MCUs have different flash memory addresses; for example, the flash memory starting address for LPC1778 is 0x0, while for STM32 it is usually … Read more
Source: Semiconductor Industry Alliance Currently, there are two types of civilizations in the world: one is the carbon-based civilization formed by human society, and the other is the silicon-based civilization composed of various chips—because almost all chips are made from single crystal silicon, the total number of chip systems far exceeds the number of humans … Read more
Since STMicroelectronics (ST) launched the first STM32 Cortex-M core MCU in 2007, over 16 years, the cumulative shipment of the STM32 series has exceeded 11 billion units, including mainstream, ultra-low power, high-performance, wireless MCUs, and five major series of MPUs. ST’s ranking in the global general-purpose MCU market has jumped from 3rd place in 2017 … Read more

There are various interfaces for LCDs, with detailed classifications. The main focus is on the driving and control methods of the LCD. Currently, the connection methods for color LCDs on mobile phones generally include: MCU mode, RGB mode, SPI mode, VSYNC mode, MDDI mode, and DSI mode. MCU mode is also referred to as MPU … Read more
Artificial Intelligence (AI) is not a new technological concept; its history can be traced back to the 1950s. Since entering the 21st century, AI has made breakthrough progress in areas such as image recognition, speech recognition, natural language processing, robotics, and autonomous driving, benefitting from rapid increases in computing power and the swift development of … Read more
In embedded development, we often encounter some professional terms, such as CPU、 MPU、 MCU and SOC, and the frequency of these terms is very high, often appearing as knowledge points in interviews. Let’s take a look at their characteristics and differences. CPU CPU is the abbreviation for Central Processing Unit， and it is the core … Read more
