Platform Flash XL High-Density Configuration and Storage Device

Description:

A reliable compact high-performance configuration bit stream storage and delivery solution is essential for the high-density FPGAs. Platform Flash XL is the industry's highest performing configuration and storage device and is specially optimized for high-performance FPGA configuration. Platform Flash XL integrates 128 Mb of in-system programmable flash storage and performance features for configuration within a small-footprint FT64 package (Figure 5). Power-on burst read mode and dedicated I/O power supply enable Platform Flash XL to mate seamlessly with the native SelectMAP configuration interface. A wide, 16-bit data bus delivers the FPGA configuration bitstream at speeds up to 800 Mb/s without wait states. See UG438, Platform Flash XL Configuration and Storage Device User Guide, for system-level usage and performance considerations.

Platform Flash XL is supported for use with Virtex-5 or Virtex-6 FPGAs only. Use with older Virtex families, Spartan® families, or AES encrypted bitstreams is not supported. Platform Flash XL is a non-volatile flash storage solution, optimized for FPGA configuration. The device provides a READY_WAIT signal that synchronizes the start of the FPGA configuration process, improving both system reliability and simplifying board design. Platform Flash XL can download an

XC5VLX330 bitstream (79,704,832 bits) in less than 100 ms, making the configuration performance of Platform Flash XL ideal for PCI Express endpoints and other high-performance applications.

Platform Flash XL is a single-chip configuration solution with additional system-level capabilities. A standard NOR flash interface (Figure 2) and support for common flash interface (CFI) queries provide industry-standard access to the device memory space. The Platform Flash XL's 128 Mb capacity can typically hold one or more FPGA bitstreams. Any memory space not used for bitstream storage can be used to hold general purpose data or embedded processor code.
