Linear BPI Flash Memory

[Figure
The Linear BPI Flash memory located at U3 provides 128 MB of nonvolatile storage that can be
used for configuration or software storage. The data, address, and control signals are connected to
the FPGA. The BPI Flash memory device is packaged in a 64-pin BGA.
The Linear BPI Flash memory can synchronously configure the FPGA in Master BPI mode at the
80 MHz data rate supported by the PC28F00AG18FE flash memory. The fastest configuration
method uses the external 80 MHz oscillator connected to the FPGA's EMCCLK pin.
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
