ISP cable schematics
I decided to put all ISP/JTAG cable circuit diagrams (schematics) in one page for easy navigation. The schematics are gathered in the internet in various web pages and datasheets. Cables are not designed by me, but I made some of them and tested. These cables can be used to program various CPLD/FPGA chips and some Atmel AVR/ATMEGA mcus.
- Xilinx parallel III.
- AVR STK200.
- Xilinx JTAG.
- Altera ByteBlasterMV.
- AVRSP LPT.
- Lattice ISP.
- Lattice ISP. I made this one. It is working.
- STK200 ISP.
- Altera Byteblaster. I made this one too, but with small modification- I added addition 5V regulator and PSU connector. So I can power cable logic from external power supply. It is useful when programming 3V logic with 5V TTL tolerant pins.
