We have a NAND chip that will not fit into the TSOP adapter, so we soldered it to the PC3K Flash Circuit Board. This is the first time we've used the circuit board and we aren't having much luck getting the system to detect and communicate with the NAND chip.

1. Are we supposed to adjust the DIP switches to a particular setting to handle TSOP chips
2. Is there a config within the program to tell it to read the TSOP layout on the circuit board?
3. Are we just going about this completely the wrong way?

I've since researched and it looks like it is a TSOP56 with 2 pins cut off on either side and found the following blog about the power board.

Do we seriously have to run wires like that? I would have thought that the connections on the circuit board would have already been wired internally.

Its not corrcet, i think so

Looks like someone trying to read TSOP-56 with Citcuit Board adapter where we have only 48-pins

It will not work, you need compatible adapter:

Thanks Roman, I didn't realize that there was a TSOP56 adapter. I guess I had better ordered in right away.

Luke Sir ,
This is very rare that you get a TSOP56 IC ,But good to have a adapter

As this is the first TSOP56 NAND I've encountered in almost 20 years of data recovery, I'm well aware at how rare TSOP56 NAND chips are.

Hello,
Have you encountered VBGA-100 In few cases or virtually not ,I am yet to get VBGA-100 and TSSOP 56.BTW the way you connected it might have fried the TSSOP 56 Module you have

Amarbir is right - it's very rare type of NAND. Usually you can find TSOP-56 in some old Samsung SSD drives, which use TSOP-56 instead BGA a few years ago.
So, maybe it would be a good idea to solder this chip like a monolith on Circuit Board. You can find pinout of TSOP-56 in ONFI.pdf in your updatebox.

As per your suggestion Roman, I had ordered in the TSOP56 adapter and just received it. It is wide enough, but not long enough for this chip. Does ACE have a TSOP56 adapter that will actually fit this chip or are we left with the more painful wiring process?

Do you have the page number where the TSOP-56 pin diagram is showing in that manual? I'm only finding TSOP-48 and BGA chip diagrams.

Very strange that adapter is not enough wide. Usually we never get problems with reading TSOP-56 chips...
Anyway, here is the pinout. It does not described in ONFI 4.0 for some reason.

But, as you can see by the photo of the chip I have, pins 1,2,27,28,29,30,55 & 56 are cut off and not present. As I said, the NAND is the same length as a TSOP48, with the width of a TSOP56 and had 56 pins, of which 8 are cut off, making it a 48 pin chip.

Well, I am now able to read the chip via the circuit board, using the pinout found here.



The Solbase shows the same controller, capacity and chip ID with a solution.

The only difference is that that chip, itself, is not the same. FG64G08UCT1-21G vs TG56G2GADA and I'm assuming that the solution chip is a true TSOP48.

In PC3K-Flash, the chip IDs, but has 4 variants, none of which are the chip I'm working with. So, a random pick of the first resulted in two dumps, ECC found, all sectors pass ECC testing, file structure all shows green, but no files that I test open.

In the process of getting the dump using a different chip alternative, but suspect that we might need to create a new entry for this white elephant chip.

I'll post a follow-up, once this project is actually done.

Luke, if you will need assistance with TeamViewer about this case - please, catch me in Skype.
