- AEC-Q100 qualified for automotive (vs SPC574K72E7C6FAR)
Design Notes
Ensure proper decoupling of the power supply pins with 100nF ceramic capacitors placed close to each VDD pin. The device requires a stable 3.3V or 5V supply. Use a bulk capacitor (e.g., 10uF) near the main power input to handle transient currents. The internal regulator can be configured for different voltage domains, so verify the configuration for your specific power scheme.
Pay attention to the crystal oscillator layout to minimize noise. Place the crystal and load capacitors as close to the XTAL and EXTAL pins as possible, with a ground plane underneath. Use the recommended 40 MHz crystal for the PLL to achieve the maximum core frequency. Keep the oscillator traces short and avoid routing other signals near them.
The SPC574K72E7 in LQFP-144 package dissipates heat through the leads and package body. For high-performance applications, ensure adequate airflow or a heatsink if the MCU is operating at high ambient temperatures. The thermal resistance (theta_JA) is typically around 40Β°C/W, so calculate the junction temperature for your power dissipation to avoid exceeding the maximum rating.
