XC3S50AN Differential I/O Alignment Differences
Also, some differential I/O pairs on the XC3S50AN FPGA are aligned differently than the corresponding pairs on the
XC3S200AN or XC3S400AN FPGAs, as shown in Table 74. All the mismatched pairs are in I/O Bank 2. The N side of each
pair is shaded.
XC3S50AN Does Not Have BPI Mode Address Outputs
The XC3S50AN FPGA does not generate the BPI-mode address pins during configuration. Table 75 summarizes these
differences.
The Spartan-3AN FPGAs are pin compatible with the same density Spartan-3A FPGAs in the FT(G)256 package, although
the Spartan-3A FPGAs require an external configuration source.
