There are many sensitive components inside a microcontroller, and these components are very sensitive to external factors. If they are affected by electromagnetic interference, it can easily lead to the system not operating normally and stably. Therefore, electronic engineers must take reasonable measures to enhance the anti-interference performance of sensitive components. So how should this … Read more
1. Introduction Recently, I received the AI8H2K12U microcontroller sent by STC company. According to its datasheet, this microcontroller has built-in USB to serial port firmware, and it does not require USB driver installation. Furthermore, it can be paired with an external power control circuit and can work with STC’s ISP software to form the programming … Read more
In the FPGA (Field Programmable Gate Array) design process, adjusting pins is a crucial task that directly relates to the stability and performance of the design. This article will discuss several aspects to pay attention to when adjusting FPGA pins! 1. Do Not Adjust VRN/VRP Pins Arbitrarily When the VRN (Reference Negative Voltage) and VRP … Read more
1. What Are Setup and Hold Times? Answer: Setup/Hold Time refers to the timing requirements between the input signal and the clock signal for testing chips. Setup time is the time during which the data must remain stable before the rising edge of the clock signal arrives at the flip-flop. The input signal must arrive … Read more
What is FPGA? What is FPGA? FPGA stands for Field Programmable Gate Array, which means a chip that can be programmed on-site. FPGA is essentially a chip, not a tool or a device, and certainly not software. It is a type of chip. FPGA can change the internal circuit structure of the chip through programming, … Read more
