The STM32L5 series of microcontrollers is one of the first to receive the PSA Certified Level 2 accreditation from Arm®, and it is now in mass production. The STM32L5x2 are available, along with the STM32L552E-EV evaluation board, the STM32L562E-DK Discovery kit, and the NUCLEO-L552ZE-Q. When we first introduced the STM32L5 at the end of 2018, its Cortex® -M33 inaugurated ST’s support for TrustZone®, which enables engineers to segregate certain resources and code in a secure environment to protect it against hacks, among other things. However, it’s only one of the many security features in the STM32L5, and the PSA Certified Level 2 certification anchors the new MCUs as a flagship solution for teams looking to prioritize advanced security features.”
