- Power Supply Complexity : Multiple voltage domains (core, I/O, analog) complicate power sequencing
- Memory Bandwidth : External memory interface may become bottleneck for data-intensive applications
- Development Complexity : Dual-core programming requires expertise in parallel processing techniques
## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Sequencing
- Pitfall : Improper power sequencing can cause latch-up or permanent damage
- Solution : Implement controlled power-up sequence: Core voltage (0.8-1.2V) before I/O voltage (3.3V)
- Implementation : Use power management ICs with programmable sequencing capabilities
Clock Distribution
- Pitfall : Clock jitter affecting signal processing accuracy
- Solution : Use low-jitter crystal oscillators and proper PCB layout techniques
- Implementation : Keep clock traces short, use ground planes, and avoid crossing other signal lines
Thermal Management
- Pitfall : Overheating leading to performance throttling or device failure
- Solution : Adequate heatsinking and airflow design
- Implementation : Use thermal vias under the package, thermal interface material, and forced air cooling if necessary
### Compatibility Issues with Other Components
Memory Interface Compatibility
- DDR SDRAM controllers require careful timing analysis
- Ensure memory devices meet timing specifications for 600 MHz operation
- Use termination resistors for signal integrity
Analog Component Integration
- Analog peripherals (ADC, DAC) require clean power supplies
