'[PIC]: EPROMS'

Happy Thanksgiving All,

I guess no one had time to look at my last posting regarding a program to
R/W a 93C56 EPROM.  So maybe
some one can point me to a program that works (mine sure does not!).  It
does not have to be for a 93C56 or
a 16F628 but it woukld be nice if it were.  I would like to use the EPROM in
the 8 bit mode.

Regards,  Royce

Happy T.G. also.  Must of overlooked your post.  I have a bunch of code in
assembler for 93LC46A and other eeproms where the processor is running at
4MHz.  I don't want to burden the bandwidth, so query me via email if you
wish.  Got some pattern R/W test code somewhere also.  Your device isn't a
93LC56A/B version by any chance?

Great!,

The device is marked 93C56 only.  I have had these chips for about 2 years.
If you could share the code I would be most happy.  This is not for
commercial,  only my amusement(?).  I really appreciate the answer.

Thanks,  Royce

There are 8 bit versions of the 93Cxx. I don't remember what manufacturer right
now, but I did some research on them and they have a mode pin that changes the
byte length from 16 to 8 bit.
