STM32L562 in STM32 Family
The STM32L562 sub-family from STMicroelectronics is a series of ultra-low-power microcontrollers based on the ARM Cortex-M33 core with TrustZone technology. Operating at up to 110 MHz, these devices provide a high level of hardware-level security and power efficiency for sensitive embedded applications. They integrate advanced cryptographic accelerators and a dedicated Secure Engine to protect intellectual property and data at rest or in transit in complex IoT ecosystems.
