## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Design :
- *Pitfall*: Inadequate decoupling causing digital noise coupling into analog sections
- *Solution*: Implement separate analog and digital power planes with proper ferrite bead isolation
Clock Management :
- *Pitfall*: Clock jitter affecting ADC performance and processing accuracy
- *Solution*: Use low-jitter crystal oscillator with proper layout and ground isolation
Thermal Management :
- *Pitfall*: Overheating in high-ambient temperature applications
- *Solution*: Provide adequate copper pour and consider thermal vias under the package
### Compatibility Issues with Other Components
Memory Interfaces :
- Compatible : Standard SPI Flash memories (up to 16MHz)
- Issues : Some DDR memory controllers may require level shifting due to 3.3V I/O limitation
Sensor Interfaces :
- Compatible : Most I²C and SPI sensors with 3.3V operation
- Issues : 5V sensors require external level shifters
Communication Interfaces :
- Compatible : Standard UART, CAN 2.0B interfaces
- Issues : May require external transceivers for long-distance communication
### PCB Layout Recommendations
Power Distribution :
- Use star-point configuration for analog and digital power supplies
- Place 10μF bulk capacitors near power entry points
- Implement 100nF decoupling capacitors within 2mm of each power pin
