Key Differentiators
- Integrated TFT LCD controller and Chrom-ART Accelerator (vs STM32F767BGT6)
- Automotive grade option available (vs STM32F769BGT6Q)
- Higher SRAM than STM32F746 (vs STM32F746BGT6)
Design Notes
The STM32F769BGT6 requires a 1.7V to 3.6V supply. Use separate decoupling capacitors (100nF) on each VDD pin and a bulk capacitor (4.7uF) on the main supply. For the VDDA pin, use a dedicated 1uF capacitor and a ferrite bead to isolate analog noise. The VBAT pin should be connected to a backup battery or tied to VDD through a diode to maintain RTC operation.
For the LQFP144 package, follow ST's recommended land pattern (AN4666). Ensure a solid ground plane under the device and route high-speed signals (Ethernet, USB) with controlled impedance (e.g., 90Ξ© differential for USB). Keep crystal oscillator traces short and away from high-current traces. Use vias for thermal relief on power pins.
Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs. Ensure the BOOT0 pin is properly set for the desired boot mode. For Ethernet, an external PHY and transformer are required; follow the reference design in AN4776. For USB, add proper ESD protection and a 1.5kΞ© pull-up on the D+ line for FS operation.
