Frequently asked questions
Can the STM32F469IGH6 run at 180MHz continuously at 85°C TA without derating?
The part is rated 180MHz at -40°C to 85°C TA, but the 201-UFBGA package has limited thermal spreading at 10x10mm. With all peripherals active (USB OTG, Ethernet, CANbus), supply current approaches the package thermal limit. Thermal management via PCB copper and firmware clock gating is the typical approach for enclosed-panel continuous operation; derating the core clock is standard practice at the high end of the temperature range.
What debug interface does the STM32F469IGH6 use, and does it support field firmware updates?
Debug is SWD/JTAG over the standard ARM Cortex Debug+ETM interface. The standard STM32F4 boot sequence applies (system memory bootloader on USART1 or USB, then Flash boot) — USB OTG and UART DFU are supported for field updates without special provisioning, but verify boot source priority for the -IH6 stepping against the current errata sheet before committing firmware to a single boot path.
