LVR, which stands for Low Voltage Reset, is a circuit protection mechanism that allows a system to automatically reset when the power supply drops below a specific threshold. This helps prevent unpredictable errors or damage to the system under low voltage conditions, ensuring system stability and improving reliability.Taking the PMS152G as an example, we can … Read more

I am a man in flip-flops, a long-term automotive electronics engineer in the magic city. As usual, I will share a piece of text I like to avoid becoming an engineer with high knowledge but low culture: After taking a shower on the weekend and changing into a new outfit, I went out but didn’t … Read more
Click the blue text above to follow us In the PC era, the Intel CPU + Microsoft Windows alliance defeated IBM; in the mobile era, the ARM architecture (Qualcomm Snapdragon, Huawei Kirin) + Android swept the market; now, in the era of “Software-Defined Vehicles”, the E/E architecture has evolved from a distributed system (with ECUs … Read more
Most MCU pins cannot measure negative voltage. Therefore, to achieve the collection of both positive and negative voltages, the circuit shown in Figure 1 can be used. This circuit converts negative voltage to positive voltage, and the specific principle is as follows. Figure 1 According to the virtual short concept, we can set the voltages … Read more
1. Overview The main control chip refers to a chip that integrates multiple functional modules such as the CPU, memory controller, input/output controller, timer, etc. The main control chip is the core of the entire system, used to manage the operation of the whole system, and is divided into CPU, GPU, MCU, FPGA, etc. This … Read more
Students and newcomers in the field often ask me: “Teacher, is a microcontroller unit (MCU) the same as a system on chip (SoC)? I see different opinions online, and I’m a bit confused. Today, let’s discuss this topic. To conclude: it is primarily an MCU, but it is increasingly resembling a SoC. 1.MCU MCU stands … Read more
SoC chips (System on Chip) are highly integrated semiconductor products that integrate all components required for a complete electronic system onto a single chip. Typically, they include processor cores, memory, digital signal processors, communication modules, and power management units. This integrated design breaks through the limitations of traditional multi-chip discrete architectures, forming a complete system … Read more
