Description

STM32U5A5VJT6 is a secure MCU from STMicroelectronics’ STM32U5 family. It’s built around an Arm Cortex-M33 core with TrustZone-M for hardware security. It runs up to 160 MHz and includes a rich set of peripherals and security features. Key features include a hardware cryptography engine (AES/DES/HASH/RSA/ECC), a true RNG, secure boot and firmware update, and memory protection. It provides standard MCU peripherals (GPIO, ADC, DAC, timers, UART/SPI/I2C, USB, CAN), plus support for LCDs and sensor interfaces, with low-power modes for energy-sensitive applications. The suffix A5VJT6 denotes a specific package/temperature option; exact flash/RAM sizes and peripherals depend on the variant; consult the datasheet. Common applications: secure IoT, industrial embedded, medical devices. Development is supported by STM32CubeMX/CubeIDE, HAL/LL drivers, and example code.
