Design Notes
The STM32U585RGT6 operates from 1.71 V to 3.6 V. Use a low-dropout regulator (LDO) or a DC-DC converter to provide a stable supply. Decouple each VDD pin with a 100 nF ceramic capacitor and a 4.7 uF bulk capacitor. For battery-powered applications, leverage the LPBAM feature to minimize power consumption in low-power modes. Ensure the VBAT pin is connected to a backup battery or tied to VDD if not used.
For the LQFP64 package, ensure proper PCB layout with a solid ground plane. Place decoupling capacitors close to the VDD and VSS pins to minimize noise. Route high-speed signals (e.g., SPI, USART) with controlled impedance and keep traces short. For the crystal oscillator pins (OSC_IN/OSC_OUT), place the crystal and load capacitors close to the MCU and avoid routing other signals nearby to prevent interference.
When using TrustZone, ensure that the secure and non-secure memory regions are correctly configured in the SAU and MPU. Failure to do so can lead to security vulnerabilities or system crashes. Also, verify that the boot mode (BOOT0 pin) is set correctly for the desired boot source. For low-power applications, avoid leaving unused GPIO pins floating; configure them as analog inputs or outputs to reduce leakage current.
Compliance Information
RoHS compliant per STMicroelectronics product page. AEC-Q100 qualification available on 'Q' variants (e.g., STM32U585RGT6Q).
