Design Considerations
Power Supply Design
Proper power sequencing ensures reliable operation:
- VCCINT (2.5V core) should power up first
- VCCO (I/O voltage) follows core voltage
- Decoupling capacitors: 0.1µF and 10µF per power pin
- Dedicated power planes recommended
Thermal Management
The 100-pin VTQFP package requires consideration for:
- Thermal resistance: θJA = 35°C/W (typical)
- Maximum junction temperature: 125°C
- Heat sink attachment for high-utilization designs
- Adequate airflow in enclosed systems
PCB Design Guidelines
Follow these best practices for optimal performance:
- Minimum 4-layer PCB recommended
- Ground and power planes for noise reduction
- Controlled impedance traces for high-speed signals
- JTAG interface placement near programming connector
