Application note
Proprietary Code Read Out Protection
on STM32L1 microcontrollers
Introduction
The protection of the intellectual property of embedded code has become a high importance issue
concerning the microcontrollers. In order to provide this protection, STM32 microcontrollers have
different means of protecting Flash code against copy and reverse engineering.
This application note describes the generic STM32 family Flash protection features. The focus is on the
Proprietary Code Read Out Protection (PCROP) which is embedded in medium-density plus
STM32L151xC, STM32L152xC, STM32L162xC and STM32L100xC microcontrollers.
Table 1 lists the microcontrollers concerned by this application note.
