A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
Use a reliable communication protocol like SPI or I2C, and ensure proper signal termination and shielding. Also, implement error checking and correction mechanisms to handle data transmission errors.
The SCC2698 has a maximum junction temperature of 150°C. Ensure good airflow, use a heat sink if necessary, and avoid blocking the thermal pads on the package. Also, follow the recommended PCB thermal design guidelines.
Use the power-down modes (e.g., sleep mode) when the device is not in use. Optimize the clock frequency, use a low-power oscillator, and minimize the number of active circuits. Also, consider using a low-dropout regulator (LDO) for power supply.
Use ESD protection devices (e.g., TVS diodes) on the input/output pins to protect against electrostatic discharge. Follow the recommended PCB layout guidelines for ESD protection, and ensure that the device is handled and stored in an ESD-safe environment.
