Some variations of the XC4000 family are no longer recommended
for new designs. These include the XC4000 standard
family, XC4000A, XC4000D, and XC4000H (referred
to in this application note as the older XC4000 families).
These have been superseded by the newer XC4000 Series
families, which include the XC4000E, XC4000L,
XC4000EX, and XC4000XL families. Designs in the older
versions of the XC4000 can be converted to the new
XC4000 Series. In some cases, particularly for XC4000D
designs or other designs not including RAM, the XC5200
family should be considered for its lower cost. For a discussion
of converting XC4000 family designs to the XC5200
family, see the Xilinx application note XAPP060, “Design
Migration from XC4000 to XC5200.”
