PS2251-13-Q / 2400097-002.A00G Information

[jeremyb]

Does anyone have any information on this controller (Phison PS2251-13-Q) or NAND chip (2400097-002.A00G)

It's an eMMC chip but I don't have a pin-out for it (eMMC or NAND interface)

I'm guessing it's an eMMC controller because on the eMMC side there aren't enough pins routed for NAND..

Some time ago I have similar case. Same controller with eMMC module. Not solved

Did you try searching for "EMMC32G-S100" rather than "2400097-002.A00G"?

http://media.kingston.com/pdfs/emmc/MKF_625_19nm_emmc_flyer.pdf

EMMC 5.0 (HS200), 32GB, 153 balls

FWIW, Intel's Compute Sticks use ...

Samsung, KLMBG4GEND-B031
Toshiba, THGBMBG8D4KBAIR
Kingston, EMMC32G-S100-WB9

Perhaps they are functionally and electrically compatible?

BTW, the ET5 part appears to be an RT8010GQW:

The media didn't fail, the client used the manufactures "password" tool and locked themselves out of the drive. I was hoping to see if the data was still accessible by reading the chip directly
which brings me to my second question, eMMC isn't really my territory, are there any off the shelf readers for eMMC that could handle this chip without requiring me to outlay thousand for a reader?

[fzabkar]

US$140 or less ?

The main control chip is ITE IT1327E-48D, which is a USB 2.0 with multi partition of SD/MMC card reader controller, T1327 built-in SD/MMC card power supply. It also integrates 5v to 3.3v voltage regulator, high speed USB 2.0 interface and downward compatible with USB 1.1.

I would be careful of the supply voltages. The adapter supplies +3.3V, but your chip might require split rails.

ISTM that it might be safer to remove the Phison controller and tap into the MMC pins.

Hi,
I was scrolling over ebay.com yesterday and this caught my eye - > https://www.ebay.com/itm/USB-2-0-eMMC-A ... SwBkRaOggb .This is based on alcor chip BTW .IF you remove this Emmc you will need nand pinout for working on it As Controller is separate .Might Be These Are All Controller Failed Emmc That Are Sold So That We Can Add Controllers and make use on nand .

Some of my friends got burned buying some of the crappy ones, too.
Have a link suggestion for good ones?

[jeremyb]

I bought this one (please note there are different dimension eMMC chips)
https://www.ebay.com/itm/152151937718

It was able to read the chip however the data was encoded.

虽然你们看到的是一颗EMMC芯片，但是群联的2251-13控制器是无法直接驱动emmc的，它的原理是把emmc芯片的nand flash引出当做传统的nand flash来使用，通过2251-13驱动。我的建议是找一个相同控制器方案的普通U DISK，通过引脚的排序去比对emmc的nand flash定义。然后同飞线的方法接入pc 3k，但是这样做的话通常需要你手动去添加 flash id，显然不是一件容易的事情

[csava]

Although what you see is an EMMC chip, the 2251-13 controller of group connection can not drive EMMC directly. Its principle is to use NAND flash of EMMC chip as a traditional NAND flash and drive it through 2251-13. My suggestion is to find a common U DISK with the same controller scheme and compare the NAND flash definition of EMMC by pin arrangement. Then connect to PC 3K by the same flight line method, but it usually requires you to add flash ID manually. Obviously, it is not an easy task.

[csava]

In my experience, if an EMMC reader tries to read it, it will find it infeasible, because the underlying data has been removed, if your client insists that you restore it. You can try the method I mentioned above. Of course, it takes a lot of time.

not sure that is an option as JB has already said :

I'm guessing it's an eMMC controller because on the eMMC side there aren't enough pins routed for NAND..

Anyway this post is a year old
