The 100-UFBGA package (7x7 mm) keeps the board footprint small, but the 81 I/Os demand careful fanout routing on a multilayer PCB.
Peripheral set includes CANbus, USB OTG, multiple I²C and SPI ports, plus a Quad-SPI interface for fast external Flash or RAM expansion. The LCD parallel interface and SAI audio serial interface support HMI and audio applications.
The base product number STM32F413 covers a range of Flash and RAM density options, so if a future BOM revision needs a different memory size, the pin-compatible siblings in the same 100-UFBGA footprint are worth evaluating.
