- Chrom-ART Accelerator for graphics (vs STM32H750ZBT6)
Design Notes
The STM32H747ZIT6 requires multiple power supply pins (VDD, VDDA, VDDUSB, etc.) and a backup battery supply (VBAT). Ensure that each supply pin is properly decoupled with a 100nF ceramic capacitor placed as close to the pin as possible, and a bulk capacitor (e.g., 4.7uF) on the main supply. The device operates from 1.62V to 3.6V, so a stable LDO or DC-DC converter is recommended. Refer to the datasheet's power supply scheme for detailed connections.
For high-speed operation at 480 MHz, careful PCB layout is essential. Use a multi-layer board with dedicated ground and power planes. Keep high-speed signal traces short and matched in length for interfaces like FMC and Ethernet. Place the crystal oscillator and its load capacitors close to the OSC_IN/OSC_OUT pins. Ensure that the STM32H747ZIT6's exposed pad (if any) is properly soldered to the ground plane for thermal and electrical performance.
A common pitfall is incorrect boot configuration. The STM32H747ZIT6 has boot pins (BOOT0, BOOT1) that must be set correctly to select the boot source (flash, system memory, or SRAM). Additionally, ensure that the NRST pin is properly pulled up and that the VCAP pins are connected to the recommended capacitor values. Failure to do so can result in startup failures or unstable operation.
Compliance Information
