Hello, I have a three new chips Winbond 25X16VSSIG who can not be programmed.
After connecting the chip to the programmer:
check devices - OK
reading - OK
deleting - OK
blank checking - OK
Writing - OK
"writing checking" but always fails at a different address
After reading the are does not match the writen file with read
Programmer says error with every chip.
