False error of serial flash memory in system level noise

In the continuous pursuit of higher performance at the system level, integrated equipment manufacturers (IDM) have become proficient in developing digital interfaces that can operate at high speed in an electrical challenge environment. Standard interfaces, such as SPI and I2C, provide a relatively simple way to interconnect devices from different suppliers in a reliable and […]

Methods and skills of basic problems in PCB design

When designing PCB, we usually rely on the previous experience and skills found on the Internet. Some rules are general at design time, and some rules can only be used for specific designs. For example, the ADC PCB rules do not apply to RF and vice versa. However, some guidelines can be considered general for […]
