Figure 13:
Configuring Multiple Devices with Design Revisioning in Slave SelectMAP Mode
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. RDWR_B (or WRITE) must be either driven Low or pulled down exernally. One option is shown.
4. The BUSY pin is only available with the XCFxxP Platform Flash PROM, and the connection is only required for high
frequency SelectMAP mode configuration. For BUSY pin requirements, refer to the appropriate FPGA data sheet.
5. In Slave SelectMAP mode, the configuration interface can be clocked by an external oscillator, or optionally the
CLKOUT signal can be used to drive the FPGA's configuration clock (CCLK). If the XCFxxP PROM's CLKOUT signal is
used, then it must be tied to a 4.7K
Ω
resistor pulled up to V
CCO
.
6 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
CCO
via a 4.7 k
Ω
pull-up resistor
