STM32U385RGI6Q

STM32U385RGI6Q is an ultra-low-power Arm® Cortex®-M33 32-bit MCU+TrustZone®+FPU. 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. This device embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, secure proprietary code, readout protection, secure, and hide protection areas. The Cortex®-M33 processor delivers a high computational performance with low-power consumption and an advanced response to interrupts. The general-purpose direct memory access (GPDMA) controller is a bus host and system peripheral. The device includes an advanced control timer, up to six general-purpose timers, two basic timers, up to four low-power timers, two watchdog timers and two SysTick timers.
