I got an unusual PNY 128GB flash drive today, it has a component I've never seen before, a chip labeled.
- Code:
AGDE
L343
The package dimensions are 6x2
None of the components have failed, I recognize the LDO right away, I'm not looking to do down that path, just identify this component.
The controller is IS903.
Also the NAND chip is interesting
NAND Reader ID: 8 x 89 88 24 4b (8GB) = 64GB
Controller ID: 4 x 89 A8 25 CB (16GB) = 64GB
I've seen SanDisk/Toshiba switch manufacture IDs (45/98) when IDing but NEVER an entire model/bank count.
By see, I mean with a logic analyzer, first ID = 45, second ID = 98.
- Code:
Flash ID code: 89A825CB - Intel JS29F64B08HAMF1 - 4CE/Dual Channel [MLC-8K] -> Total Capacity = 128GB
Flash ID mapping table
----------------------------
[Channel 0] [Channel 1]
89A825CBA900 89A825CBA900
89A825CBA900 89A825CBA900
89A825CBA900 89A825CBA900
89A825CBA900 89A825CBA900
Before thinking the controller ID code is erroneous, why would it return a valid NAND chip ID, much less one of the proper capacity?
