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 In Slave Serial mode, the configuration interface can be clocked by an external oscillator, or
4 For the XCFxxS the CF pin is an output pin. For the XCFxxP the CF pin is a bidirectional pin.
optionally—for the XCFxxP Platform Flash PROM only—the CLKOUT signal can be used to drive the
FPGA's configuration clock (CCLK). If the XCFxxP PROM's CLKOUT signal is used, then CLKOUT must
be tied to a 4.7KΩ resistor pulled up to V
XCFxxP, if CF is not connected to PROGB, then it must be tied to V
