I'm experimenting with the ATF1502 series and I'm surprising myself about programming them:
- If I limit myself to 32 I/O pins I can use JTAG and use a dirt cheap USB Blaster from AliExpress
- If I want to use all 36 pins you suddenly need an astromically expensive programmer (?)
- The ATF22V10C is really amateur friendly, you can use the affordable TL866 programmer from Autoelectric to program it
- But should you want to upgrade to an ATF750, the more powerful drop-in replacement, you again need an astronomically expensive programmer (?)
As I understand the programming algorithm is top-secret, so no way that you can design your own programmer as an amateur.
Do I view this correct?
