- *Solution*: Implement 10μF ceramic capacitor within 5mm of VDD pin, plus 100nF placed adjacent
Thermal Management Issues
- *Pitfall*: Overheating during continuous operation
- *Solution*: Incorporate thermal vias in PCB, ensure adequate copper pour, consider forced air cooling for ambient >85°C
Signal Integrity Problems
- *Pitfall*: Noise coupling in sensitive analog circuits
- *Solution*: Separate analog and digital grounds, use guard rings for critical traces

Power Supply Requirements
- Input voltage range: 2.7V to 5.5V
- Incompatible with unregulated supplies >6V
- Requires clean power source with <50mV ripple
Clock Synchronization
- Internal oscillator accuracy: ±2%
- For precision timing, recommend external crystal with load capacitors
