Frequently asked questions
Does STM32F446ZCT6JTR require an external crystal for USB OTG full-speed operation?
The part uses an internal oscillator as the primary clock source. USB OTG full-speed at 48MHz is generated from the PLL — whether the internal PLL meets USB peripheral certification accuracy for your application depends on your specific USB compliance requirements. Check the STM32F4 reference manual PLL characterization against the USB-IF timing margins for your use case before removing an external crystal from the BOM.
