For general-purpose MCU chips, the CPU operating frequency ranges from 100 to 300 MHz, while the frequency of typical crystals (xtals) is usually in the tens of MHz range. Therefore, MCUs typically use a PLL module to multiply the frequency to the hundreds of MHz range.Similarly, taking the STM32F10xxx series as an example, let’s examine … Read more
