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.
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.
