VC707 Evaluation Board Features
80 MHz oscillator connected to the FPGA's EMCCLK pin with a bitstream that has been
built to divide the configuration clock by two. The division is necessary to remain within
the synchronous read timing specifications of the flash memory.
Multiple bitstreams can be stored in the Linear BPI Flash. The two most significant address
bits (A25, A24) of the flash memory are connected to DIP switch SW11 positions 1 and 2
respectively, and to the RS1 and RS0 pins of the FPGA. By placing valid XC7VX485T
bitstreams at four different offset addresses in the flash memory, 1 of the 4 bitstreams can
be selected to configure the FPGA by appropriately setting the DIP switch SW11. The
connections between the BPI Flash memory and the FPGA are listed in
.
