1. Although STM32F103x6 devices are not described in this datasheet, orderable part numbers that do not
show the A internal code after temperature range code 6 or 7 should be referred to this datasheet for the
electrical characteristics. The low-density datasheet only covers STM32F103x6 devices that feature the
A code.
