STM32U545CET6Q

STM32U545CET6Q is an ultra-low-power Arm® Cortex®-M33 MCU+TrustZone®+FPU, 240 DMIPS, 512KB flash memory, 274KB SRAM, crypto. The device embeds high-speed memories (512Kbyte flash memory and 274Kbyte SRAM), one Octo-SPI flash memory interface, an extensive range of enhanced I/Os, peripherals connected to three APB buses, three AHB buses and a 32bit multi-AHB bus matrix. The device offers a security foundation compliant with the TBSA (trusted-based security architecture) requirements from Arm®. It embeds the necessary security features to implement a secure boot, secure data storage, and secure firmware update. Besides these capabilities, the devices incorporate a secure firmware installation feature, that allows the customer to secure the provisioning of the code during its production. The device features several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, secure and hide protection areas.
