Lattice also has a 22V10 that's a little more versatile
and can be programmed in circuit. Part number is: ISPGAL22V10
Tanks, but i need to use the PALCE20V8. I don't have the opcion of choose another because the PAL is in a circuit.
Since you are using a nonISP device, it must be socketed. What is wrong with using the ISP device Dave suggest as it is functionally equivalent (except for programming method).
