Number of digital component that can be fit on a single PSoC 3 part

Question: How many of each digital component can I fit in the reconfigurable UDBs on a single -3866 PSoC 3 part?

 

Answer:

It depends on the configuration of the component, but some general guidelines are shown below. Remember that there are fixed function blocks in PSoC 3 whose features overlap with those of the UDBs. Also remember that the versatility of PSoC often allows functions to be implemented in new and more efficient ways than rival microcontrollers.
