That speed handles most industrial control loops, Modbus polling, and USB packet processing without timing margin issues."},{"question":"What is the closest pin-compatible alternative to STM32F105VBT6?","answer":"The STM32F107VBT6 is pin-compatible and adds Ethernet MAC, but requires an external PHY. The STM32F103VBT6 shares the same footprint but lacks USB OTG host capability. For a drop-in with identical connectivity, the STM32F105VBT6 is the baseline choice."},{"question":"What compliance documentation does ST provide for STM32F105VBT6?","answer":"STMicroelectronics provides RoHS and REACH compliance declarations for this part. The 100-LQFP package is lead-free and meets the EU RoHS directive.
