UT210E eprom revival
« on: October 05, 2023, 06:15:07 pm »
Hi all

I have been trying to flash the ATMEL chip via my ch34a programmer and i initially wired everything (5 cables) directly to the board 1-2-3-4 all gnd and so on... it did not work, then removed the chip from the board but cannot read the memory with my ch34a , no way.... in case the eprom is damaged what are the symptoms turning on the clamp? because now it shows some strings like random and then staus forever at DC 000.0 but measures nothing.... i imagine that the chip is empty... what can i do?

fixed with another chip found around at 24c02N and also modified my ch34 to 3.3v pins 9 and the first as the diagram lying around.thks__________________
