b. Super speed USB microcontroller programmer schematic

Super Speer USB programmer is besed on a preprogrammed PIC18F24J50. Time critical functions were moved to firmware therefore the programmer is more than 60 times faster. Programming PIC18F24J50 with 16kB of program code takes only about 4 seconds. Programming PIC18F26J50 with 64kB of program code takes only about 11 seconds.
