Author Topic: does anyone know what the biggest size of 48pin tsop nand is? (Read 5030 times)

I am hoping to modify a ipod nano and a mini gen 3 the ones with nand soldered to the board. I used to fix a lot of ps3s and modify and hack them and noticed( and kind of figured) that the storage type was 48pin tsop nand. So I went on digikey and mouser to look for sizes, digikey didnt really have anything but mouser had many options 256gbx8 128gbx8 etc. etc. etc. The mini has 1 slot So I'm trying to find the biggest tsop nand size there is (hopefully 128gb). Anyway 256gb/8 would be the 32gb so that would be the biggest size on mouser. I've seen these on ssd's as well so I took a look on Ebay and found a 64gb. the nano gen 1 has 2 memory slots so 2 64gb is pretty good.

Is there anyone who works in memory on this site? Id love to now what the biggest size single tsop ever made was I figure the firmware is on one of the main board chips not the memory as that's how apple does the classics and many of their other Ipods and that the tsops are solely just memory with nothing on them until you put music on.

It's not enough for it to have the same package, it also needs to have the same pinout and be compatible in terms of supply voltage and programming. A good start would be to determine what part the OEM used.

hynix kor hy27uv08bgfm tpcb 2048 x8 and x16 config 8bit 3.3v https://datasheetspdf.com/pdf-file/1231801/HynixSemiconductor/HY27UV08BGFM/1 Partly the reason im wondering what the biggest tsop nand ever made is if its worthwhile trying to find a memory that will work in this ipod.

I have one open right now a mini and that is the memory model. They were all made in the same year so I assume gen 1 nano uses the same.

also couldnt I get a tsop programing board and change the pin layout if need be?

This one looks the same they just use different terminology https://datasheet.lcsc.com/szlcsc/1908271118_Micron-Tech-MT29F64G08CBABAWP-B_C410865.pdf / label system that one looks like a 8gx8 so I assume 8 seperate 8gb chips. maybe that means 8bit tho as it says on the top of the hynix datasheet.

Well, the 4-die Hynix part has 4 CE#'s and 4 R/B#'s. It's not clear from looking at the datasheet that Micron offers the same 4-die configuration in TSOP-48.

What do you mean by 4 die aaahhh I just read the data sheet fully f is the 4 die version of the Hynix chip good eye. ill have to look out for that .

psxpetey1 · « **Reply #5 on:** October 14, 2020, 01:30:21 am »

apparently it does come in quad but your right it doesn't show on the dataset anywhere, I'm trying to find out which product code is what chip but the document is super long, I may have to call micron and ask lol. It definitely would be awesome if they have a 128gb tsop that would make my day, I'm hoping they have a 256 or 512 config too that would rock

bson · « **Reply #6 on:** October 14, 2020, 03:46:08 am »

Yeah, the datasheets are pretty massive, and all the nitty gritty details are buried deeply somewhere...

But, if you can find a 4-die Micron part it looks like it should work! I wonder though what would happen if a 2-die part were used instead and the extra CE#'s ignored... probably nothing good!

But it could also be the firmware is smart enough to probe around and use what's actually installed.

I have a gen2 4GB nano, which has a Samsung K9MCG08U5M, a quad TSOP-48 (12·20mm). This family has a weird 2112 byte page at the end of each 1GB die. As long as the firmware doesn't use that I'm thinking it should be possible to drop in pretty much any of the quad Microns, and as long as it gets the device info and doesn't barf at the sheer size of a 64GB device, it should be good. But even a dual might work; the 2GB gen2 nano had only a dual die chip after all. So the firmware may just adapt to whatever is populated. You have me curious if it'll just work! So I ordered a couple of MT29F128G08CFABBWP-12IT:B from Mouser to see if it'll work. If not I'll just solder the original back on, and will undoubtedly find some use for a couple of sizeable NAND flash chips in a future project...

The quads are a tad pricey!

Yesterday Youtube recommended a video (sorry, can't find it) where a guy put 4 TB into an ipod. He used a board that used 4 SD cards. There were a lot of issues going past 2 TB.

psxpetey1 · « **Reply #9 on:** October 14, 2020, 11:07:19 am »

That just has to do with the ram size which is 64mb on the classic and 64gb on the nano 3rd gen

The iPod nano gen 1 has 32 mb and 2 tsop slots

iOS can handle about 50 thousand songs on 64mb so the original nanos are good for about 25000

Rockbox can handle much more but the file size doesn’t matter so if you have high fidelity songs you can fill most of that.

The highest iPod classic I’ve seen is 2tb but that’s a bit nuts lol 🥜

psxpetey1 · « **Reply #10 on:** October 14, 2020, 11:09:20 am »

It might be the original nanos use 2 die and apparently a guy on another forum has a nano gen 3 that uses Toshiba memory and he said it was 2 die I’ll have to check the data sheet on that one tho.

psxpetey1 · « **Reply #11 on:** October 14, 2020, 01:26:54 pm »

that model the MT29F128G08CFABBWP-12IT:B is that quad or dual I cant find the datasheet on that. I went to micron and found they have UP TO 256gb in tsop nand x8 I cant find a datasheet but I requested one from micron. MT29F256G08CJABBWP-12IT:B Freaking awesome!

bson · « **Reply #12 on:** October 14, 2020, 05:00:16 pm »

The datasheet is the one you posted... It's a 2-die. The 2-die costs $20, the 4-die about $150. I'm not that excited about the gen 2, but $20 seems like the right price just to experiment.

psxpetey1 · « **Reply #13 on:** October 14, 2020, 05:45:39 pm »

Ahhhh I understand I thought you meant the 4die version but it seems like you found the 4die version did you have a link for that one?

I think I’ll go and buy the 2die version as well because 150 is pretty crazy but it would be a good resource to have in my memory banks in case I decide to spring for it.

I couldn’t find the 4die on mouser

Just in case you may need this resource page to read nand info: https://www.freemyipod.org/wiki/Modes , I was watching iPhone storage upgrades and they seem to need to program some kind of identifier to the nand using either a programming station when the chip is off or a box like the irepair dfu box I’ll be using those resources and hooking up the iPod to figure out what they are/ do.

As per this wiki the iPods nano 2g and up use a on chip bootrom on the cpu or something which confirms what I thought.

I also wanted to do this on the iPod nano 1g as I like the look of that one as much as I like the classic and it has 2 nand spots with 32mb of ram whereas all the good models and 2g and up have 64mb.

48 pins

When I was still in the s1mp3 scene many years ago (and biggest flash was 16GB = 128Gbit, with 2GB = 16Gbit and below being the norm) memory upgrades were a common thing and the firmware would autodetect capacity. You might be able to stack two dual-CE parts and do a bit of fine wiring to effectively get a quad-CE. 2112 bytes is a common page size, 2048 main area + 64 ECC/spare bytes. The newer (and less reliable) flash, beyond 4LC(MLC), uses a bigger spare area for more ECC, but you're dealing with "old school" stuff.

bson · « **Reply #17 on:** October 16, 2020, 03:32:28 am »

For the 4/8 die part #... if you look in the datasheet it has a section:

So you see the second letter after the 08 (the bus width): B, E, F, J ,K, M, U

Of these, the J, K, M are 4-die. U is 8-die. The J and K have only 2 CE and 2 R/B#, meaning they're shared between pairs of dies. (Not sure how they make do with fewer CE#'s without a wider bus, but maybe the LUNs are internally coupled.) For example, MT29F128G08AJAAWP is a 4-die. (@ $154!)

Might be a tight squeeze fitting them into an iPod nano... not much room in there!

1024 + 64 ecc bits = 2112. Of course! Thanks!

I’d definitely be interested in seeing a diagram of how you would do that. These iPods are cheaper than dirt and the broken ones even cheaper I can buy like 35 for 100$ so even if it wouldn’t fit it’s be cool to try since the 2 die are only 27$ I also have 40awg wire at the ready

psxpetey1 · « **Reply #20 on:** October 16, 2020, 03:57:55 am »

Lol I need to stop skimming this was exactly the page I was trying to find! It seems the m variant has 4 die 4 ce 4rb like the Hynix. Mouser doesn’t carry it tho so I’d have to get a quote but I can only imagine it’s more than the j version.

I called mouser the other day and they were like 4 die saaaay whaaat. The lady who answered sounded like tree trunks from adventure time lol. But they got an engineer on the phone and he didn’t know either. If I had of seen this I definitely could have expedited the process. 200cad ouchies!

Interesting I wonder if the iPod can drive the extra 3.3v of power it will require or at the very least the 2.6 it will need

It looks like the devices with fewer CE#'s than dies and a single 8-bit bus would require synchronous DDR access and might not support an async bus at all. (I.e., WE# is turned into a dual-edge clock used to access the odd-even LUN pairs.)

It looks like installing L4N/Rockbox is the easiest way to get a 2G Nano to work with any arbitrary flash.
