In microcontroller chips, multiple groups of VDD designs are often seen. This design is intended to ensure power stability while reducing signal noise. This article will explore why multiple VDD groups are needed on microcontroller chips from the perspectives of internal circuit structure, power consumption, EMI/EMC, and how to design the VDD power system. 1. … Read more

ESD: Electro-Static Discharge refers to the release of static electricity. Static electricity is a natural phenomenon that usually occurs through contact, friction, or induction between electrical devices. It is characterized by long-term accumulation, high voltage (which can reach thousands or even tens of thousands of volts), low charge, small current, and a short duration of … Read more
