Ghi chú thiết kế
Place 0.1uF and 1uF ceramic capacitors close to each VDD and VDDA pin. Use a 10uF bulk capacitor on the 3.3V supply. Ensure the analog supply (VDDA) is properly filtered with a ferrite bead to reduce noise from digital switching. Follow the datasheet's recommended decoupling scheme to maintain stable operation at 100 MHz.
The boot mode pins (GPIO72, GPIO73, GPIO74, or similar) must be configured correctly at reset to select the desired boot source (e.g., SCI, SPLASH). Incorrect boot configuration can prevent the MCU from starting. Consult the datasheet's Boot ROM chapter. Also, avoid drawing large currents from GPIO pins directly; use external drivers for high-load peripherals.
At 100 MHz operation, the TMS320F280021-Q1 dissipates power based on supply voltage and activity. Ensure adequate copper pour and thermal vias under the LQFP-48 package to keep the junction temperature within the recommended range. For automotive applications, consider ambient temperatures up to 125°C; calculate power dissipation using the datasheet's power consumption tables.
Use a four-layer PCB with a solid ground plane. Route analog and digital grounds separately and join at a single point to minimize noise. Keep the crystal oscillator circuit short and away from high-current traces. For high-frequency switching, maintain short trace lengths for PWM outputs to reduce EMI and ensure signal integrity.
