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 analog and digital grounds.
Use a pull-up resistor on the SCL and SDA lines, and ensure that the total capacitance on the bus is within the recommended limit. Also, use a common ground point for all devices on the bus.
The MB3773PF-G-BND-JN-ERE1 is rated for operation from -40°C to +85°C. However, the device may not function correctly outside this range, and reliability may be affected.
The POR and BOR features are enabled by default. To disable them, tie the POR and BOR pins to VCC. To use them, connect the pins to a capacitor to set the reset timeout period.
Use a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel, placed as close to the VCC pin as possible. This helps to filter out noise and ensure stable operation.
