Device development process
STM32 series product development process (see
), compliant with the IATF 16949 standard, is a set of
interrelated activities dedicated to transform customer specification and market or industry domain requirements
into a semiconductor device and all its associated elements (package, module, sub-system, hardware, software,
and documentation), qualified with ST internal procedures and fitting ST internal or subcontracted manufacturing
technologies.
