1. Concept Composition of Power Consumption: Three main sources of power consumption: surge, static power, and dynamic power; Surge Current: Refers to the maximum instantaneous input current generated when the device is powered on, known as the inrush current; The surge current is device-dependent; Surge power is not our primary concern, so it is only … Read more
Low Power Design 5.1 Power Consumption Sources Surge、Static Power Consumption and Dynamic Power Consumption are the three main sources of power consumption. • Surge current refers to the maximum instantaneous input current generated when the device is powered on, and is also known as startup current in applications. • Standby current refers to the current … Read more
Smart homes, industrial IoT, wearable devices, and smart surveillance are currently hot topics of interest. Enhancing the AI processing capabilities of edge computing will significantly improve the intelligence level of terminal devices. In this context, edge AI has entered a fast track of development in recent years. The MCU is the most widely used processor … Read more
The BLE protocol is established by the Bluetooth Special Interest Group and is widely used in short-range communication fields with low power requirements, such as smartwatches, fitness bands, smart lighting, and mice. The protocol is relatively mature. The SparkLink technology, introduced by Huawei, is a new wireless communication standard, with the SLE (SparkLink Low Energy) … Read more
1. Overview STM32CubeMX is a member of the STM32Cube tool family, providing STM32 developers with a simple, convenient, and intuitive way to perform tasks such as MCU/MPU selection, pin configuration, system clock and peripheral clock settings, and peripheral parameter configuration, as well as middleware parameter configuration. After all configurations are completed, it can also generate … Read more
Comparing LCD screens and OLED screens is akin to comparing fuel vehicles with electric vehicles. The acceleration and power levels are simply not on the same scale. The emergence of new technologies inevitably leads to the obsolescence of older ones, often without any warning. Nokia phones are a prime example of this. First, let’s understand … Read more
Overview Integrated circuits are composed of chips (die) cut from silicon wafers (wafer). Each wafer can yield hundreds of chips. ASIC stands for Application Specific Integrated Circuit, which is designed for specific applications, unlike general-purpose memory, microprocessors, etc. There are several types of ASICs: Full-Custom ASIC: This type of ASIC is completely manually designed, without … Read more
Recently, while chatting with a prominent figure in the industry, we discussed the topic of chip tape-out failures. I found this to be quite an interesting subject, so I gathered some reasons for chip tape-out failures online and would like to share them here. 1. Incorrect version of the design was used. This issue is … Read more
Power consumption is a critical performance metric in chips, sometimes even determining the success or failure of a chip. As is well known, the recent “Snapdragon Fire Dragon” incident significantly impacted the market share of this chip. For industrial-grade and automotive-grade chips, the impact of power consumption is not very apparent. However, for consumer-grade chips … Read more
Accurate thermal analysis plays a crucial role in the design of many electronic products, particularly in high-end PCB design. The results of thermal analysis often influence the mechanical layer design of the PCB and the product’s enclosure: whether to install heat sinks, cooling fans, etc. If a cooling fan is installed, it often needs to … Read more
