Footprint Migration Differences
Unconnected Balls on XC3S50AN
Table 73 summarizes any footprint and functionality differences between the XC3S50AN and the XC3S200AN or
XC3S400AN devices for migration between these devices in the FTG256 package. The XC3S200AN and XC3S400AN have
identical pinouts. The XC3S50AN pinout is compatible with the XC3S200AN and XC3S400AN, however, there are 51
unconnected balls and one functionally different ball. Generally, designs migrate upward from the XC3S50AN to either the
XC3S200AN or XC3S400AN. If using differential I/O, see Table 74. If using the BPI configuration mode (parallel Flash), see
In Table 73, the arrow (
) indicates that this pin can unconditionally migrate from the device on the left to the device on the
right. Migration in the other direction is possible depending on how the pin is configured for the device on the right.
