The STM32L562E-DK Discovery kit is a complete demonstration and development platform for Arm' ' Cortex' '-M33 with Arm' ' TrustZone' ' and ARMv8-M mainline security extension core-based STM32L562QEI6Q microcontroller, with 512 Kbytes of flash memory and 256 Kbytes of SRAM. The STM32L562E-DK Discovery kit uses the STM32L562QEI6Q innovative ultra-low-power oriented features to enable prototyping for many wearable or sensor applications, with state-of-the-art energy efficiency, secure boot, and TrustZone' '-based software isolation. For even more user-friendliness, the on-board STLINK-V3E debugger provides out-of-the-box loading and debugging capabilities, as well as a USB Virtual COM port bridge.
