When you reading the note above you are probably wondering why I am mentiong FPGA vs CPLD etc ...
1) available logic
2) number of avaialble i/o's
3) $$$
some desgins I looked at from xilinx for example wouldn't even fit in the largest CPLD availalbe and even if they did they were way more expensive then the small fpga (logic slice)
anyway thats the designers job ...find the best device to fit the application ...
