Integrated Ethernet and FlexRay (vs SPC58EC74E5)

Design Notes

Ensure stable power supply with proper decoupling capacitors (100nF and 10uF) close to each VDD pin. The SPC58EC74E7 operates at 3.3V to 5V, and voltage spikes can cause erratic behavior. Use a dedicated power plane and avoid sharing with high-current loads.

The LQFP-176 package has a thermal resistance of approximately 20°C/W. At maximum core frequency and full peripheral usage, power dissipation can reach 2W, resulting in a 40°C temperature rise. Ensure adequate airflow or a heatsink for high-temperature environments.

For high-speed interfaces like Ethernet and FlexRay, maintain controlled impedance traces and keep trace lengths short. Use ground planes to minimize noise. For the ADC, separate analog and digital grounds to prevent noise coupling.
