7.6. Fast Passive Parallel Configuration

The FPP configuration scheme uses an external host, such as a microprocessor, MAX® II device, or MAX V device. This scheme is the fastest method to configure Cyclone® V devices. The FPP configuration scheme supports 8- and 16-bits data width.

You can use an external host to control the transfer of configuration data from an external storage such as flash memory to the FPGA. The design that controls the configuration process resides in the external host. You can store the configuration data in Raw Binary File (.rbf), Hexadecimal (Intel-Format) File (.hex), or Tabular Text File (.ttf) formats.

You can use the PFL IP core with a MAX II or MAX V device to read configuration data from the flash memory device and configure the Cyclone® V device.

Note: Two DCLK falling edges are required after the CONF_DONE pin goes high to begin the initialization of the device for both uncompressed and compressed configuration data in an FPP configuration.
