“Energy consumption”, “carbon emissions”, “range anxiety” – these issues in the semiconductor field are closely related to chip power consumption. Currently, we are in the midst of a digital wave, accompanied by the booming development of technologies such as the Internet of Things, mobile computing, autonomous vehicles, and data centers. Chip designers are facing a … Read more
Have you ever worked on low power consumption products? Low power products may seem simple, but to create a low power product, especially achieving ultra-low power consumption, is relatively more challenging. Today, we will discuss the approach to low power design in an RTOS environment. Preface: Programming Mindset The design of embedded products is diverse … Read more
Design Discrepancies, Moving On During module integration, the frontend blames the backend for conservative timing constraints, while the backend complains about the frontend’s redundant logic…Every step in chip design can lead to “signal conflicts” between departments. “The power consumption of arguments is far greater than chip leakage.” Moving on does not mean abandoning one’s position, … Read more
If you don’t pay attention to me, you won’t know what you’ve missed! Everything starts with connection. The Internet of Things (IoT) is accelerating into our daily lives and various industries, with increasingly intelligent and convenient connections between people and things, and between things and things. Wireless communication has become an invisible bridge in IoT … Read more
Before the tape-out of IC chips, ensuring the reasonableness and reliability of the driver and load design is a crucial step. The existence of the driver and load will directly affect the chip’s performance, power consumption, and yield. So how should this be done? 1. Verification of Metal Line Current Carrying Capacity Strictly assess whether … Read more
The “Understanding at a Glance” series explains common terms and concepts of 8-bit MCUs in the most straightforward way. Unlike traditional explanations of the 8051, this series will combine products and practices from mainstream microcontroller manufacturers in the current market (such as Zhongx, Shengx, Xinx, Yingx, Jiux, etc.) to analyze core knowledge in a simple … Read more
Introduction: Although 3.3V is becoming increasingly popular in modern microcontrollers, and general system designs tend to adopt lower supply voltages, the 5V voltage level still holds significant importance and remains a popular design choice. This is mainly due to the higher voltage of 5V providing better anti-interference capabilities and stability in signal transmission, along with … Read more
I2C (Inter-Integrated Circuit) is a widely used bus protocol for data communication between MCUs and many chips, including the commonly used EEPROM chips from the AT24 series. The I2C bus consists of a serial clock line (SCL) and a serial data line (SDA). When developing an MCU as an I2C master, the GPIO pins corresponding … Read more
In SoC (System-on-Chip) design, clock design is a core and highly challenging task that directly affects the chip’s performance, power consumption, reliability, and testability. A robust SoC clock architecture needs to consider multiple factors. Core Objectives. Functional Correctness: Ensure all modules operate on the correct clock edge, meeting timing constraints. High Performance: Provide clock frequencies … Read more
Click the blue text to follow us In the fields of smartphones, televisions, and monitors, OLED and LCD are the two mainstream screen technologies. They both seem capable of presenting stunning images, but the underlying working principles and the final experiences are vastly different. Understanding their differences can help us make more informed choices. 1. … Read more
