Frequently asked questions
Does the STM32F437VIT7TR need an external crystal for USB OTG?
Yes. The internal oscillator cannot meet the ±0.25% frequency tolerance USB full-speed requires across the full operating temperature range. An external crystal — typically 8 MHz on the HSE pins — is mandatory for USB OTG compliance. Budget the crystal and its matched load capacitors as a required hardware element, not an option.
Is the built-in Ethernet controller self-contained or does it need an external PHY?
The Ethernet peripheral is MAC-only. An external PHY (MII or RMII) must be added between the MCU and the network connector for any IEEE 802.3 link. This is a separate BOM line item and layout consideration that the part itself does not satisfy.
