JL Bluetooth IC ID

[Quarlo Klobrigney]

I'm trying to identify this series of JL Bluetooth ICs while I wait for some modules from China.
They all start with AS20BP0xxxx.

Does anybody have a datasheet, just a pinout is OK as well.

My main thing is a "connected" pin to toggle VCC used to control other things.

My old modules had them but have been raised in price and are becoming more scarce.

Here are a few module part numbers:

Could be one of AC6903 AC6907 AC6925
Some Jerry Bluetooth
Some schematics to compare

[Quarlo Klobrigney]

I don't see anything that qualifies as a (TSOP?) 24 except the AC6907A and who knows if it is or not.... 

China likes to hide the datasheets.

Hopefully there will be someone that can shed some light on these ICs.
 
I hate to have to wait a month+ to find out.

[gabiz_ro]

Is something like TSOP24 or QSOP24.
When received you can compare pinouts vs some schematics to identify what IC is.
And datasheets are really simple,just some basic info for example like
https://cdn.datasheetspdf.com/pdf-down/A/C/6/AC6905A-Jieli.pdf

[Quarlo Klobrigney]

Yes I understand, but the idea was to have the info before they arrive. I need to start designing the "power on toggle" to a PCB.

Look here if you want to go down that rabbithole: https://www.eevblog.com/forum/projects/datasheet-for-chinese-parts/msg2720674/#msg2720674

Rabbit hole fully explored and found no rabbits. At least I don't feel alone in this pursuit

[Quarlo Klobrigney]

Well the modules are in and I didn't see the page 2 of the link you provided.
looking at the PDF on http://www.chenbingdom.com/uploadfile/201721417233513763.pdf I found the typical 6905A schematic. My version is pinning out to this one. My question is could it be an OTP part or in the picture below, is there a way to either access it through SPI or the USB. If USB, what would be the IO voltage? It appears to be 5V. I already have the CSR programmer so I'm not worried about the SPI port as the programmer will do 1.8V and 3.3V. Any smarter folks than me here that can give me a clue as to the point of attack on this module? Thanks.

OOps  the USB section

[gabiz_ro]

Not sure about 6905A but when I search for some info,some time ago,I remember that I see somewhere something about firmware.
Do something on USB (send command or some pattern of hi-lo on data pins) and switch chip in programming mode.
I'll try to find it again and post link,but was on russian or chinese site.

That's what I found looking in browser history

[Quarlo Klobrigney]

Thanks, but I saw all of those links.

The Jim link was hard to understand and his software links don't work.
I think Russian one didn't explain too much.
Both of the above are in the readme.md of https://github.com/christian-kramer/JieLi-AC690X-Familiarization
After making a PDF of it, and reading many words, I found that in the last line he says that he wasn't able to upload the firmware to the module

Even this reading and document PDF'ing has not cured my insomnia as it is 02:47 local time and I still can't  again.

Perhaps tomorrow later today I'll play again with some USB software and see what the readback is.

Thanks I did already see the Reddit posts. Half of the stuff leads to dead links even the Wayback Machine has no archive of.
However that last archive.zip looks very promising! More software tools to try.
Thank you for helping with this.
If I ever do find a way to make any software/hardware work, I'll share/post all the info here.

Interesting, good to see others doing some more digging on these. Anyone found a full datasheet yet?

It is said that it has sold more than 4 in 17 years

[Quarlo Klobrigney]

Translated into Chinglish. The statement should have said:
"it has sold more than 4 Billion in 17 years"
Instead of "It is said that it has sold more than 4 in 17 years. Billion,"

Hi!
I know that this is an old thread but here are my two cents to it:
I have ordered pack of 10 Bluetooth adapters and Bluetooth chips (QSOP-24 Package) on them have writing: AS23BP1F938-65A4.
My suspicion after quick search on the web is that digit's after AS on them, represent manufacturing year and relevant part is after “-“ dash.
Here is official manufacturer github side with lots of information, firmware and tools:
https://github.com/Jieli-Tech
Regards,

P.S. I think my AS23BP1F938-65A4 is AC6965A chip with 4 Mbit Flash memory " A=QSOP-24 Package" and "4=4 Mbit Flash memory" thast the definitions of "65A4" after  “-“ dash.

"Jerry Bluetooth audio chip AC6965A, equipped with a high-performance 32-bit CPU, the chip comes with 4M-bit flash,

Support: MP2, MP3, WMA, APE, FLAC, AAC, MP4, M4A, WAV, AIF, AIFC; 10-segment sound effects can be adjusted;

Jerry's Bluetooth headset chip AC6965A is compatible with V5.1+BR+EDR+BLE; the Bluetooth headset chip is packaged in QSOP24."

Belov is Seller description of an item and pictures where I order it from:
"VHM-314 Bluetooth Audio Receiver Board Bluetooth 5.0 Mp3 Lossless Decoder Board Wireless Stereo Music Module 10Pcs"

Here is Diagram of AC6965A (original in Chinese and Google Translated one from me):

[Quarlo Klobrigney]

OK, I had relegated this project to the dust bin.


I will have to pop this off the project priority stack address where it was buried at a very deep level.


Thanks I will look further at the GitHub files, but the naming conventions are vague at best.


Thanks for the update it's never to late in a post where info is concerned, just at an awkward time to instantly jump back on the project.
 

[Kaluluka]

Well, you ones should be these two (AC6925A with 25A4  and AC6925F with 25F4 after DASH):


LINK to manufacturer for AC6925x:

[Kaluluka]

Today little more Information about these chips.
Seems like AC6925A is same as TD5325A
and AC6965A is same as TD5165A or maybe TD5161A from (Tudasemi) here:

Hi Quarlo have you figured out how to program the chip at all? I received a crappy bluetooth speaker for free with one of these chips (a `AS22BP17637-65E4`) and I'm going to try to use it in a project.

[amyk]

That's an AC6965E with 4Mbit flash. There's a lot more information on them here: https://kagaimiq.github.io/jielie/

https://github.com/kagaimiq/jl-uboot-tool

[Quarlo Klobrigney]

Never did! I got really busy and opted for the cheaper option of the next China version with BT 5 #3.

I was trying to detect either a voltage level shift to do switching with the older version #2 and instead opted for a messy switch instead.
I get so busy I have to move forward, but I do have a few #2's I may try later .

The #3's at start just yack away as they boot up   .
The #2's at start had a Windows USB plugin sound 30dB over the program level.

Nothing appears to be just right with these things that I would call perfect for the 2.3 cents that it would take to make them right from the factory in the beginning....

Hi!
Who knows anything about chip JL:  AB24C102155-65A ?

It is impossible to take a photo, the text is very pale. 

[amyk]

As others upthread have mentioned already, that is an AC6965A.
