   I'm new to CPLD/FPGA.
   Andrew (or anybody who can), could you tell, please, what
approximately is a minimal price of 0.13 micron CPLD/FPGA
capable of containing a sort of PIC18FXXX plus some spare
cells for application to be flash-programmed.
   Is it possible to move programm code from built-in FLASH to
built-in SRAM on reset? If so, is it true, the device would be
10 times as fast?
   Is it true, that power consumption would dramatically drop due
to the 0.13 micron technology and ability to switch off unused cells?

   Thank You very much.
   Mike.
