ID codes and locking mechanism
There are several ID codes inside the STM32F10xxx MCU. ST strongly recommends tools
designers to lock their debuggers using the MCU DEVICE ID code located in the external
PPB memory map at address 0xE0042000.
MCU device ID code
The STM32F10xxx MCU integrates an MCU ID code. This ID identifies the ST MCU part-
number and the die revision. It is part of the DBG_MCU component and is mapped on the
external PPB bus (see
debug port (4 to 5 pins) or the SW debug port (two pins) or by the user software. It is even
accessible while the MCU is under system reset.
