- Power Management : Requires careful power sequencing and backup power planning
## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Supply Issues:
- Pitfall : Inadequate decoupling causing signal integrity problems
- Solution : Implement distributed decoupling capacitors (100nF ceramic + 10μF tantalum) near each power pin
Signal Integrity Challenges:
- Pitfall : Long, unmatched trace lengths causing timing violations
- Solution : Maintain trace length matching within ±50 mil for address/data buses
- Pitfall : Ground bounce affecting read/write operations
- Solution : Use dedicated ground planes and multiple vias for return paths
Timing Violations:
- Pitfall : Setup/hold time violations due to improper clock distribution
- Solution : Implement clock tree synthesis with careful attention to skew management
### Compatibility Issues with Other Components
Voltage Level Compatibility:
- 3.3V Systems : Direct compatibility with standard 3.3V logic families
- Mixed Voltage Systems : Requires level shifters when interfacing with 1.8V or 2.5V components
- Power Sequencing : Ensure proper power-up/down sequencing to prevent latch-up
Interface Compatibility:
- Microprocessors : Compatible with most 32-bit processors through asynchronous SRAM interface
- FPGAs : Direct connection possible with appropriate I/O banking and timing constraints
- Bus Controllers : Requires proper timing analysis with memory controllers
