Features available only in the STM32WL5x dual-core line

In addition to its wireless and ultra-low-power features, STM32WL microcontrollers include embedded security hardware

functions such as 128- / 256-bit AES hardware encryption, PCROP read / write protection, and public-key cryptography with

an elliptic curve encryption engine. The dual-core line STM32WL5x also provides advanced security features.
