Notes:
1 For Mode pin connections and DONE pin pull-up value, refer to the appropriate FPGA data sheet.
2 For compatible voltages, refer to the appropriate data sheet.
3 For the XCFxxS the CF pin is an output pin. For the XCFxxP the CF pin is a bidirectional pin. For the
XCFxxP, if CF is not connected to PROGB, then it must be tied to V
