## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Sequencing
- Pitfall : Improper power-up sequencing can cause latch-up or permanent damage
- Solution : Implement controlled power sequencing with monitoring circuitry
- Implementation : Use power management ICs that ensure core voltage (2.5V) stabilizes before I/O voltage (3.3V)
Clock Distribution
- Pitfall : Clock jitter and skew affecting signal processing accuracy
- Solution : Use low-jitter clock sources and proper clock distribution techniques
- Implementation : Implement clock tree synthesis with matched trace lengths and termination
Memory Interface Timing
- Pitfall : Timing violations in external memory interfaces causing data corruption
- Solution : Careful timing analysis and proper wait state configuration
- Implementation : Use manufacturer-recommended timing parameters and validate with signal integrity simulations
### Compatibility Issues with Other Components
Memory Compatibility
- SDRAM Interfaces : Limited to 16-bit wide SDRAM with specific timing requirements
- Flash Memory : Requires voltage level translation for 3.3V Flash devices
- SRAM Compatibility : Standard asynchronous SRAM works well but requires proper timing configuration
Mixed-Signal Integration
- ADC/DAC Interfaces : Compat
