How to Configure FPGA with XC17S20XLVOG8C
The configuration process for the XC17S20XLVOG8C serial PROM follows a straightforward sequence.
Master Serial Configuration Process
- Power-Up Sequence: Apply VCC to both the PROM and FPGA simultaneously
- Reset Release: The PROM’s internal address counter resets to zero
- Clock Generation: The FPGA generates configuration clock pulses
- Data Transfer: Serial data appears on the DATA output after each clock edge
- Configuration Complete: The FPGA asserts DONE, disabling the PROM
Design Recommendations
- Connect the PROM DATA pin directly to the FPGA DIN pin
- Use a 4.7kΩ pull-up resistor on the RESET/OE pin
- Ensure both VCC pins are connected together
- Add proper decoupling capacitors (0.1µF) near VCC pins
