Finally, I managed to used vvdi prog programmer to read 4J74Y on EIS W639!!


Used wiring as 1L02M + OSC to 59pin = right and enough….but for read choice from MCU –> MC68HC(9)08 –> HC908AZ60 EEP (4J74Y) and success….i read through this way more 4J74Y in W639 EZSĀ all successfully readed

For wiring diagram for this MCU in W639 EZS coming soon in some next VVDI Prog SW update i think…

Made some pictures of this type W639 EZS with this MCU and with other one as 3K85K too
