Will there be support for this IC in the future?

GQ-4X can program MX29L3211 already and the only difference is that MX26L6420 got A21 and instead of BYTE it is WE.

So maybe it's already possible with ADP-019 V4 and higher?

Not the same technology at all.

Because it only use 16 bit mode? ADP-019 programm in 8 bit mode I assume?

No, mainly because it's not in the same family of chips.
MX29 is a FLASH EEPROM an can be accessed by sectors or pages and supports 10000 cycles.
MX26 is more like a conventional EPROM and only supports 100 erase/program cycles.

Oh, I see. Any chance it can be added to support list though?

Probably...

Hi, any update on the implementation of the PSOP44 MX26L1620/3220/6420 or even /12811 to the support list?

Thanks

Hi, trying to make my own adapter for those but still struggling on which model i should twist to read/write MX26L6420.

I've made a custom version of the 16bit adapter with relocation of the pins. CE on chip is set to Low (GND) while CE(GQ4X) goes to WE thru a 100 Ohms resistor. Vpp (GQ4X) is not used as those are single voltage eproms.
