STM32U535JEY6QTR

STM32U535JEY6QTR is an ultra-low-power Arm® Cortex®-M33 MCU+TrustZone®+FPU, 240 DMIPS, 512Kbytes flash memory, 274KB SRAM. The Cortex®-M33 core features a single-precision FPU (floating-point unit), that supports all the Arm® single-precision data-processing instructions and all the data types. The Cortex®-M33 core also implements a full set of DSP (digital signal processing) instructions and a MPU (memory protection unit) that enhances the application security. The devices embed high-speed memories (up to 512-Kbyte flash memory and 274-Kbyte 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 32-bit multi-AHB bus matrix. The devices offer 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.
