For a long time, communication between microcontrollers (MCUs) has been a learning challenge for many electronic engineers. Since different MCUs may use different voltage levels, many beginners are curious about how these MCUs can communicate. Let’s take a look! Generally speaking, communication between MCUs relies on digital signals, where the voltage level of the digital … Read more
After 2019’s “Spider-Man: Far From Home”, Marvel experienced more than a year of “downtime”. “WandaVision” at the beginning of 2021 brought us back to this vast universe and kicked off Marvel’s fourth phase. The fourth phase includes a series of films and series released by Marvel from 2021 to 2022, starting with “WandaVision” (not counting … Read more

The microcontroller (MCU) serves as the heart of electronic products and is widely used in consumer and industrial electronics. Today, the development of industrial automation, next-generation vehicles, smart analytics, and the Internet of Things has raised the performance requirements for edge MCUs, leading to increasing demands for performance, real-time control capabilities, and diverse and high-speed … Read more
A traditional fuel vehicle requires about 500 to 600 chips, a mild hybrid vehicle requires about 1000 chips, and plug-in hybrid and pure electric vehicles require at least 2000 chips. This means that with the rapid development of smart electric vehicles, the demand for advanced process chips is increasing significantly, and the demand for traditional … Read more
MIT (Massachusetts Institute of Technology) published a paper in 2018 titled “The Decline of General-Purpose Computing: Why the End of Moore’s Law and Deep Learning is Leading to Computing Fragmentation”. This paper predicted that as Moore’s Law slows down and the costs of cutting-edge semiconductor manufacturing processes rise, general-purpose computing would struggle to meet the … Read more
In embedded development, we often encounter some technical terms, such as CPU, MPU, MCU, and SOC. These technical terms are frequently used and are often topics of questions in interviews. Let’s take a look at their characteristics and differences. CPU CPU stands for Central Processing Unit, which is the core of computation and control in … Read more
Automobiles are the largest and most promising application scenario in the domestic MCU industry. The MCU is the core chip for automotive control. With the development of smart vehicles, users continually raise new demands for the safety, stability, and intelligence of cars. The realization of each in-car function requires the stable support of complex chipsets … Read more
When it comes to microcontrollers (MCUs), the first thing that comes to mind is that they have many input/output (I/O) ports, which can be difficult to distinguish. As the core of embedded systems, they can communicate with external devices or sensors. However, the presence of I/O ports often makes learning challenging for many people. This … Read more
As the demand for battery life in terminal devices increases, low-power MCUs are becoming more widely used. So, what is a low-power MCU? Which categories have a strong demand for low-power MCUs? What trends are emerging in the development of low-power MCUs? Wide Application Scenarios “Typically, low-power MCUs utilize different design methods and processes compared … Read more
