REVELTRONICS

Hi all, I am requesting help in programming a 93c46 eeprom! I am trying to make a backup of my chip, and i am able to read it with no issue and save it to a bin file. However, when i try to write the bin file to a new chip, it comes back with a write error and will not allow me to write,(verify) to the chip, it fails at the first address. So my first question is, does this programmer set the enable\disable registers on the chip, before writing? If not can you someone point me in the right direction or offer a solution to enable writing and verification.

93xx chips do not have any locking registers which require to reset before write.

Do you programming it as 8-bit or 16-bit? Which 93C46 do you have exactly? (full signature / datasheet).

The actual chip is a NMC93c46 EN. The datasheet I am using for this chip,is attached for reference. I have tried programming in 8bit and 16bit mode, but the same issue. The data sheet on page four states the chip has to have a write enable instruction to be sent before attempting a write!

Please select EEPROM -> 93 series -> NMC -> NMC9346 and it will work.

It worked,thank you so much for your help, i will not have to pull out what little of my hair remains now
