Flash NAND Lite Memory Programmer! TSOP48

funak 407649 558

TL;DR

  • Built a low-cost Flash NAND Lite programmer for TSOP48 NAND chips, aimed at reading and programming memory from sticks, routers, televisions, modems, and navigation devices.
  • The board runs from USB 5.0V, generates 3.3V with a TPS781330220 LDO, and uses an XMEGA-A4U plus FT245 USB converter with a parallel data bus.
  • The design exposes four CE lines and four RB lines, while the LDO’s 150mA overcurrent protection helps prevent damage if a chip is inserted backwards.
  • Measured throughput reached 980kB/s from FT245 to XMEGA and 2.7MB/s from NAND to XMEGA, showing much faster direct NAND communication.
  • The main limitation is cost-cutting simplicity: only one permanently soldered TSOP48 socket is included.

    Count yourself what nonsense AI writes. 2048*64*2048 = 2Gb and earlier it writes 4Gb.
    Tested experimentally and it is supposed to be LUN=2, 2048, 64, 2048+128.

    The earlier description referred to the image not the TH58NVG2S3 chip

    Write to the manufacturer maybe they will provide documentation but knowing life they will not even write back but it does not hurt to try.

    If you set LUN to 1, will it read the memory?

    Take a look here, although I don't know how reliable the data they give there is:

    if I set the LUN to 1 and the number of blocks to 4096, which corresponds to 4Gb, it will not read. Lun=1 and B=2048 will read but half of it, i.e. 2Gb.

    Another question, I guess to the author, about the logic behind the programmer and its software. What does this kit actually read from the memory page? It reads the raw content of the USER DATA + SPARE Bytes, is the USER DATA area already polynomially corrected ?

    Could the author of the software clear up any doubts about how to read the memory ?
    I have never done any project on parallel NAND but I have done on serial, the difference is probably only in the interface.
    It would be great if there was a possibility to set in the software whether we read the "raw" memory and its "spare bytes" or whether we read the data already corrected by the ECC mechanism of the memory itself. Either method has its uses for other purposes.

    The NANDLite programmer reads the raw data, and does not include polynomial correction due to the different algorithms and byte locations that are taken for calculations.

    "Reads raw USER DATA + SPARE Bytes".

    And isn't it enough to enable correction in memory and then you read from the user area data already polynomially corrected according to the memory algorithm ? This is the case in serial.

    Not enough, because the memory MUST have ECC support. and unfortunately most common NAND memory does not have ECC support, so you have to do your own (processor) counting.

    Examples of memory with ECC are BeNAND

    Sure. It's just that my whole notion of NAND was based on this one project I did and assumed equivalence between the types. Thanks for the clarification.

    LUN introduced such a concept MICRON and in general it is of little relevance in most cases as long as the addressing of the parties is uniform.

    In the case of TOSHIBA they did a little bit of work and it turns out that in some memories the addressing is discontinuous, i.e. page numbers in a block are addressed, for example, 0..85, then it is necessary to issue a command to change the page set and again address 0..85 and there are, for example, 3 such sets.

    It is just a puzzle how to unify this :) .

    I don't remember if it was the same with blocks, i.e. we address blocks sequentially, let's assume from 0..4200.
    To address the next one you have to select the next LUN and again address 0..4200.
    And we have a discontinuous address space.

    We will worry about this in the new version of the programmer.

    Added after 20 [minutes]: .

    Ok, found:

    TC58NVG6T2FTA00

    That is, 64Gbit, in the middle each block has numbered pages 0..85
    then changing the set of pages and again numbering 0..85 of the same block

    In total each block has 258 pages of 9216 bytes.

    There are 4156 blocks.

    I encourage you to read for curiosity :) .

    Hello. I have seen reference to updating the firmware of the NANDLite. How is the .hex update performed?

    Also, has anyone else been unable to have the unit seen by the software? Choosing a COM port fails from all available choices. My problem is I bought a Chinese bootleg version before I knew there was an official one. I will probably return it and buy from Funak, but I worry I will have the same problem.

    Just an amateur hobbyist here, but with a large interest in backup of this type. I am very much looking forward to backing up my Toshiba TH58NVG3S0HTAI0 and reviving my old TV. Any advice for apps to help turn the image into a file system? Apologies for my Polish, as I used Google Translate.

    Many thanks!



    Hi. I've seen mention of a NANDLite memory firmware update. How does the .hex update work?

    Has anyone else failed to detect the device with the software? The COM port selection is not working from all the options available.

    29F16G08CBA... = 16Gb MLC.

    That is, the programming possibilities are so-so.
    Of course the programmer will handle such memory, you can read, write, but here I see programming only in 1:1 mode, whether we write bit by bit, byte by byte, sector by sector.
    Which means that if we encounter a corrupted memory block, writing that particular memory block will fail. But the others should write. Another thing is that for this particular memory

    Table showing memory error management details for NAND flash device

    we can see that for one 4096B sector, ECC is recommended at 24bit.

    Which means that in practice, during programming, erroneous 2-3 bits should not cause problems.

Topic summary

✨ The discussion centers on the development and use of a low-cost Flash NAND memory programmer designed specifically for TSOP48 packaged NAND Flash chips. The programmer targets applications such as reading and programming NAND Flash from devices like flash drives, TVs, routers, and modems, offering an affordable alternative to expensive professional tools. The design includes a permanently soldered TSOP48 socket and uses an FT245 USB interface combined with an Atmel XMEGA microcontroller for flexible control and hardware timing measurements. Software development focuses on supporting various NAND Flash memory types, including multi-die ("4 die") memories, and implementing error correction algorithms such as BCH capable of correcting multiple bit errors per 512-byte sector. The NANDLite application supports reading, writing, erasing, and batch uploading of NAND dumps for analysis and algorithm improvement, including handling bad block tables (BBT) and ECC data correction. Specific NAND Flash models like Samsung K9GAG08U0E and Toshiba TC58NVG6T2FTA00 are extensively tested, especially in relation to Samsung D5500 series TVs. Challenges discussed include addressing discontinuous memory spaces, bad block management, different addressing schemes (e.g., Toshiba's additional page addressing commands), and the complexity of NAND file systems like UBIFS. The project is evolving with plans for faster data transfer rates (up to 50MB/s in future versions), improved software interface, multilingual support, and expanded memory support including eMMC in the future. Comparisons with commercial programmers such as RT809H and Lens-Men highlight differences in speed, functionality, and openness of software. The community contributes NAND dumps for analysis to enhance error correction and bad block handling algorithms. The discussion also touches on hardware considerations like the quality of Chinese TSOP48 sockets, USB driver compatibility (including Windows XP support), and the limitations of TSOP48 packaging as industry shifts toward BGA and FBGA packages, suggesting ISP programming as a future direction.
