## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Design:
- Pitfall : Inadequate decoupling causing digital noise coupling into analog circuits
- Solution : Implement separate analog and digital power planes with proper ferrite bead isolation
- Implementation : Use 10μF bulk capacitors plus 100nF and 1nF ceramic capacitors close to each power pin
Clock Configuration:
- Pitfall : Incorrect clock tree configuration leading to timing violations
- Solution : Carefully configure internal main oscillator (IMO) and phase-locked loop (PLL) settings
- Implementation : Use internal low-speed oscillator for sleep modes to reduce power consumption
Analog Performance:
- Pitfall : Poor analog signal integrity due to improper grounding
- Solution : Implement star grounding with separate analog and digital ground connections
- Implementation : Route analog signals away from high-speed digital traces and clock sources
### Compatibility Issues with Other Components
Mixed-Signal Integration:
- Voltage Level Matching : Ensure compatible logic levels when interfacing with 1.8V or 3.3V devices
- Solution : Use level shifters or configure I/O banks for appropriate voltage standards
- ADC Reference : External reference voltage sources must have low noise and high stability
Communication Interfaces:
- I²C/SPI Timing : Verify timing compatibility with slave devices, especially at higher clock frequencies
- UART Baud Rates : Ensure precise clock configuration to maintain accurate baud rate generation
- USB Connectivity : Requires precise 48MHz clock for full-speed USB operation
### PCB Layout Recommendations
Power Distribution:
- Use 4-layer PCB minimum (signal, ground, power, signal)
- Implement separate power planes for analog (VDDA) and digital (VDDD) supplies
- Place decoupling capacitors within
