XC17S30APD8I Configuration Interface
The XC17S30APD8I provides an easy-to-use interface for storing Xilinx FPGA configuration bitstreams. When the Spartan device operates in Master Serial mode, it generates a configuration clock that drives the PROM. After each rising clock edge, data appears on the PROM DATA output pin connected to the Spartan device DIN pin.
The PROM interface connections include:
- DATA output → Spartan device DIN input
- CLK input ← Spartan device CCLK output
- RESET/OE input ← Spartan device INIT pin (with pull-up resistor)
- CE input ← Spartan device DONE output (directly or inverted)
