Frequently asked questions
Can the STM32F439IGH6 be field-upgraded over USB OTG or Ethernet from an existing STM32F4 firmware ecosystem?
USB OTG and Ethernet are present on-die, so the hardware supports field upgrade. Direct firmware portability from an LQFP100 variant requires I/O remap — the 201-UFBGA pinout and multiplexing differ from the LQFP100 package, and a revised pin-assignment file is needed before the existing binary will run.
What does the eol_hot status mean for my procurement risk?
It means this part is in formal end-of-life qualification — a confirmed last-time-buy date is expected from ST's official PCN. Channel quantity is not quoted here; request current allocation and LTB dates from your distributor or ST sales rep before locking panel-build quantities. Excess-stock return terms are a commercial arrangement to be confirmed separately.
