Hi!

Could anybody please help with some advices?

I'm trying to make a copy of a 93C56.
The original is marked B05AG 93C56 EM8.
The eeprom I try to copy to is marked ST 93C56WP B423G.

When I read the original I have to use 16 bit in order to get the binary correct.

The problem is: It is not possible to write to the eeprom using 16 bit, only 8 bit, even the eeprom should support 16 bit as well.

Here is a photo of my hardware with the 93C56 placed in a SOIC8 adapter.

Do anybody have an idea what I am doing wrong or what might be the problem?

It looks all right.

Make sure your chip pin contacting good.

Also, use 0.97ja version software. That is a good version as knew.
