01 eMMC Signal Impedance and Routing It is recommended to use ground wrapping for CLK and STRB signals, with a ground via every ≤500 mil. During overall layout,eMMC should be placed as close to the SOC as possible to minimize routing length. The reference layer for all eMMC signals must be a complete ground plane … Read more

Recently, a reader asked a question: What communication technologies should one master when working with microcontrollers?With the development of technology, there are more and more communication technologies, but in the embedded field, the common communication technologies are actually not many, such as UART, I²C, SPI, CAN, USB, and TCP/IP, which are the most common.These communication … Read more
90% of USB drives are modules, which are composed of chips and surrounding components, such as PCB capacitors and resistors. Why do we have products like modules? For example, CPUs and MCUs can be directly soldered onto the motherboard. This represents a direct relationship between the chip and the motherboard, but many products cannot be … Read more
