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 such as SPI or I2C, and ensure proper signal termination and routing. Also, use a common clock source and ensure the microcontroller and CY25814SXC are synchronized.
The CY25814SXC is rated for operation from -40°C to +85°C. However, it's recommended to operate within a narrower range (e.g., 0°C to 70°C) for optimal performance and reliability.
Ensure that the power supply voltage (VCC) is stable and within the recommended range before applying the reset signal (RST). Hold the reset signal low for at least 10 ms to ensure a clean reset.
Use 0.1 μF to 1 μF ceramic capacitors for decoupling, placed as close as possible to the VCC pin. Additional decoupling capacitors may be required depending on the specific application and PCB layout.
