Notes de conception
For ultra-low-power operation, use the low-speed external oscillator (LSE) and configure the device to enter Stop mode with RTC wake-up. Ensure that all unused GPIOs are configured as analog inputs to minimize leakage current. The typical current consumption in Stop mode is in the microamp range, but this depends on the configuration and supply voltage.
Place 100nF decoupling capacitors close to each VDD pin and a 4.7uF capacitor at the main power input. For the LQFP package, ensure proper grounding with a solid ground plane. The exposed pad (if present) should be soldered to the ground plane for thermal and electrical performance.
When using TrustZone, ensure that the secure and non-secure memory regions are correctly configured in the SAU and MPU. Incorrect configuration can lead to hard faults or security vulnerabilities. Also, verify that the boot mode (BOOT0 pin) is set correctly for the desired boot source (Flash, SRAM, or system memory).
