XC4000 Compared to XC3000A
For those readers already familiar with the XC3000A
family of Xilinx Field Programmable Gate Arrays, here is a
concise list of the major new features in the XC4000 family.
CLB has two independent 4-input function generators.
CLB has very fast arithmetic carry capability.
CLB function generator look-up table can also be used as
CLB flip-flops have asynchronous set or reset.
CLB has four outputs, two flip-flops, two combinatorial.
CLB connections symmetrically located on all four edges.
XC4000 outputs can be paired to double sink current to
IEEE 1149.1- type boundary scan is supported in the I/O.
Wide decoders on all four edges of the LCA device.

A third function generator combines the outputs of the
two other function generators with a ninth input.
All function inputs are swappable, all have full access;
none are mutually exclusive.

24 mA. XC4000A and XC4000H outputs can each
sink 24 mA, can be paired for 48 mA sink current.
