## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues
- Pitfall : Unstable operation during power-up sequences
- Solution : Implement proper power sequencing and decoupling capacitors (100nF ceramic + 10μF tantalum per power pin)
Clock Configuration
- Pitfall : Incorrect clock source selection causing timing inaccuracies
- Solution : Use internal 24MHz IMO with calibration or external crystal for critical timing
Analog Performance
- Pitfall : Poor ADC accuracy due to noise coupling
- Solution : Separate analog and digital grounds, use dedicated analog power supply
Programming and Debugging
- Pitfall : Locked device due to incorrect security settings
- Solution : Always maintain backup programming interface and follow manufacturer programming guidelines
### Compatibility Issues with Other Components
Voltage Level Compatibility
- Operating voltage: 2.4V to 5.25V
- 3.3V Systems : Direct compatibility with level shifters rarely needed
- 5V Systems : Ensure I/O voltage configuration matches system requirements
Communication Interfaces
- I²C Compatibility : Standard 100/400kHz operation
- SPI Compatibility : Master/slave modes up to 2MHz
- UART : Standard asynchronous serial communication
Mixed-Signal Integration
- Analog blocks may require external components for optimal performance
- Digital I/O limited to 3.3V/5V logic levels
