Description
Xilinx introduces the Platform Flash series of in-system pro-
grammable configuration PROMs. Available in 1 to 32
Megabit (Mbit) 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-Mbit, 2-Mbit, and 1-Mbit PROMs that
support Master Serial and Slave Serial FPGA configuration
modes (Figure 1). The XCFxxP version includes 32-Mbit,
16-Mbit, and 8-Mbit PROMs that support Master Serial,
Slave Serial, Master SelectMAP, and Slave SelectMAP
FPGA configuration modes (Figure 2). A summary of the
Platform Flash PROM family members and supported fea-
tures is shown in Table 1 .
