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
pair is shaded.

XC3S50AN Does Not Have BPI Mode Address Outputs
The XC3S50AN FPGA does not generate the BPI-mode address pins during configuration.
differences.
Table 75: XC3S50AN BPI Functional 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.
