Word Count: 2250 Content Index: ⭐⭐⭐⭐⭐ Every new application design requires either a microcontroller or a microprocessor. When choosing between the two, several factors need to be considered. Below is an overview and comparison of microprocessors and microcontrollers. When considering whether to choose a microprocessor (MPU) or a microcontroller (MCU), the type of application is … Read more
In today’s article, let’s discuss how to choose an MCU. I’ll share my thought process. 1. List the Available Peripherals If a system has multiple MCUs, we need to allocate them properly, for example, temperature sensor on MCU #1, Bluetooth on MCU #2, and so on. 2. Determine the Communication Interfaces of the Peripherals Some … Read more
This article mainly shares an open-source management module that helps achieve layered management of applications and hardware in an MCU project. Nowadays, project requirements are more complex, which naturally imposes stricter demands than before. From a technical perspective, I still recommend that everyone should maintain a layered structure (application and driver) in their projects. This … Read more
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
