## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Issues:
- Pitfall : Inadequate decoupling causing analog performance degradation
- Solution : Implement proper power supply filtering with 0.1μF ceramic capacitors close to each power pin
Clock Configuration:
- Pitfall : Incorrect clock source selection leading to timing inaccuracies
- Solution : Carefully configure internal and external oscillators according to application requirements
Analog Performance:
- Pitfall : Poor analog signal integrity due to digital noise coupling
- Solution : Implement proper grounding strategies and use separate analog and digital power planes
### Compatibility Issues with Other Components
Voltage Level Compatibility:
- The 3.3V I/O may require level shifting when interfacing with 5V components
- Use appropriate level shifters or voltage dividers for mixed-voltage systems
Communication Interface Compatibility:
- UART, SPI, and I²C interfaces are standard but may require configuration matching
- Ensure baud rate and protocol compatibility with connected devices
Analog Interface Considerations:
- Input impedance of ADC channels (typically 1-10kΩ) must be considered when designing analog front-ends
- External op-amps may be required for high-impedance sensor interfaces
### PCB Layout Recommendations
Power Distribution:
- Use separate analog and digital ground planes connected at a single point
- Implement star-point grounding for analog sections
- Place decoupling capacitors (0.1μF) within 5mm of each power pin
Signal Routing:
- Keep high-speed digital traces away from sensitive analog traces
- Use ground planes as reference for all critical analog signals
- Route clock signals with controlled impedance and minimal
