Xilinx introduces the Platform Flash series of in-system programmable configuration PROMs. Available in 1 to 32 Mb densities, these PROMs provide an easy-to-use, cost-effective, and reprogrammable method for storing large Xilinx FPGA configuration bitstreams. The Platform Flash PROM series includes both the 3.3V XCFxxS PROM and the 1.8V XCFxxP PROM.

The XCFxxS version includes 4 Mb, 2 Mb, and 1 Mb PROMs that support Master Serial and Slave Serial FPGA configuration modes (Figure 1, page 2). The XCFxxP version includes 32 Mb, 16 Mb, and 8 Mb PROMs that support Master Serial, Slave Serial, Master SelectMAP, and Slave SelectMAP FPGA configuration modes (Figure 2, page 2). When driven from a stable, external clock, the PROMs can output data at rates up to 33 MHz. Refer to "AC Electrical Characteristics," page 16 for timing considerations.

The MT25Q is a high-performance multiple input/output serial Flash memory device. It features a high-speed SPI-compatible bus interface, execute-in-place (XIP) functionality, advanced write protection mechanisms, and extended address access. Innovative, high-performance, dual and quad input/output commands enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.
