設計說明
The TMS320F28P550SG-Q1 in LQFP-100 package has a thermal resistance of approximately 22 C/W (theta_JA). At 150 MHz with all peripherals active, power dissipation can reach 1.5W, causing a 33C rise above ambient. Ensure adequate copper pour under the package and consider airflow for high-temperature automotive environments.
Place 0.1uF ceramic capacitors on every VDD and VDDIO pin, with at least one 10uF bulk capacitor near the MCU. Use ground planes for VSS, and keep the ADC reference pins clean with dedicated ferrite beads. The VREFLO pin on 128-PDT packages should be tied together at PCB level.
Separate analog and digital ground domains, connecting at a single star point near the MCU. Route PWM output signals with controlled impedance to minimize EMI, and keep the ADC input traces short and shielded from switching nodes to prevent noise coupling.
