- Automotive grade option (vs SPC58NG84C3-Q1)
- Higher core frequency (vs MPC5748G)
Design Notes
The SPC58NG84C3 requires a stable 3.3V or 5V supply. Use a low-dropout regulator (LDO) with adequate current capability, and place 100nF decoupling capacitors close to each VDD/VSS pair. For analog sections, use a separate analog supply (VDDA) with a ferrite bead to isolate digital noise.
The LQFP-144 package has a thermal resistance of approximately 40Β°C/W (theta_JA). At 180 MHz with all peripherals active, power dissipation can reach 1.5W, resulting in a 60Β°C temperature rise. Ensure adequate airflow or a heatsink for high-temperature environments. The device is rated for -40Β°C to +150Β°C junction temperature.
For reliable operation, use a multi-layer PCB with dedicated ground and power planes. Place the crystal oscillator and its load capacitors close to the XTAL/EXTAL pins. Route high-speed signals (Ethernet, FlexRay) with controlled impedance and keep them away from analog traces. Follow STMicroelectronics' layout guidelines in the datasheet.
