概述

Description

STM32U585QII3 is STMicroelectronics’ STM32U5 microcontroller in a secure, Cortex-M33-based MCU. It runs up to 160 MHz and uses Arm TrustZone-M for hardware-enforced security, with a crypto engine (AES, RNG, PKA/ECC) and secure boot to support secure IoT and edge applications.
Key points:
- Security: TrustZone-M, hardware crypto, secure boot, memory protection.
- Core: ARM Cortex-M33, FPU, up to 160 MHz.
- Memory options: sizeable Flash/RAM (variant-dependent).
- Peripherals: broad mix (USB, CAN, I2C/SPI/UART, timers, ADC/DAC, etc.) and safety/low-power features.
- Package: QII3 denotes a specific ST package variant (pinout/footprint in that family).
Development: supported by STM32CubeMX, HAL/LL libraries, and the broader STM32 ecosystem.

Features

Key features of STM32U585QII3:
- Core and security: Arm Cortex-M33 with TrustZone-M, single-precision FPU, DSP instructions.
- Speed: Up to 160 MHz.
- Memory: Up to 2 MB flash and up to 640 KB RAM.
- Security and cryptography: Hardware crypto engine (AES/DES/TDES, SHA-2), RNG/TRNG, secure boot, MPU/MPU-like memory protection.
- Peripherals: USB 2.0 Full/High-Speed OTG (device/host), CAN FD, multiple USART/UART, I2C, SPI/I2S, SDMMC (SD/SDIO), LCD-TFT controller.
- Analog and timing: Multiple 12-bit ADC channels (multi-channel), extensive timers/PWMs, DMA with DMAMUX.
- Power and range: Operating voltage 1.65–3.6 V; supports ultra-low-power modes with VBAT retention.
- Package and ecosystem: 100-pin LQFP (QII3); supported by STM32CubeMX/HAL/LL libraries for easy development.
- Additional features: SWD/JTAG debug interface, robust security and reliability features suitable for secure, low-power applications.
