[sdiy] Read/write/save DS1630AB complete partitioned data to a PC file.. found a solution..

[Jean-Pierre Desrochers]

Since the DS1630 seems to be hard to read/write/save
on a specific programmer (can’t find one),

Here is what I’ll do :

 

·         Remove the ‘about to die’ DS1630AB from my TDS350 scope

·         Read it in my programmer as a standard 32k x 8 SRAM using part# DS1230 instead

·         Save the complete device data to my PC

·         Verify each of the 16 x 2K chunks that are read-only by trying to write to each of them and note them on paper

·         Put aside the original DS1630AB

·         Install another DS1630AB which has been dremeled (and has an external 3V lithium battery) to the programmer

·         Program it with the just saved 32k x 8 data (all bytes write enable here)

·         Disconnect it from the programmer (external 3V battery always connected)

·         Connect it to a small home made Microchip PIC based adapter that will program the 16 x 2k chunks

With the same read-only setup as the original one untouching the data itself.

·         Disconnect it then connect it back to my programmer still using DS1230 part# instead

·         Compare the data with the saved PC data

·         Test each 2k chunks and verify their read_only setup from the original one.

·         If everything compare I have a good DS1630AB (with external 3V Battery) to use in the TDS350 scope

 

 

That’s it.

Many diyers on this list gave me many tips to 

Replace a DS1630AB partitioned SRAM from my TDS350 scope

And I thank you all.

 

Now I’m struggling to find a programmer/reader that will 
be able to ‘talk’ to this device..

I already have a multi-programmer that works well for many devices
including micros and RAMS (standard RAMS) but does not
list the DS1630 in its supported devices..

I checked renowned programmers like Logical Devices
and even them don’t support this partitioned RAM IC.

If Anybody have a programmer name to suggest …

That would help a lot !
