integrated circuit - Indentifying a JL chip in a Bluetooth - ...

I'm new to electronics and my Bluetooth speaker broke and want to fix it. This is the chip I think I need to replace. Can anyone help me find this chip's datasheet? I just need to know what each pin does. I have tried to find it but I couldn't find any info on it. Maybe because it's from a dirt cheap speaker. ... This appears to be a part number specific to the programming of the CPU/DSP based on a generic part. For example, here is a datasheet for the Zh-Jieli JL AC6905A that has a BT 4.2 radio. It may be that buyers order a specific programming and the actual number JL stamps on the device may be tagged to the buyer. It seems that even specs for a generic device can't be found on their site and I don't know why. It's possible this PDF might be the one for yours, try following some of the signal paths and see if they agree with the pinout. So I believe what you'd need to do is find another board with a chip that has the same number and lift it, because it seems you can't order one from anywhere.

I tried googling the markings on these to figure out what the chip was called, but they seemed to be serial numbers, and not model numbers you'd typically find on western ICs. All I had left was the weird "JL" symbol... So I googled "jl bluetooth chip" to see what would come up, and wouldn't you know! Apparently, the "JL" is the logo for "JieLi", which is the company that designed and manufactures these, and the actual model number of the 24-pin chip is the AC6905A, a low-cost all-in-one bluetooth chip found in many bluetooth audio devices made in China. Now that I know what it is, maybe I can find some sort of minimal development board containing this chip on Amazon so I can quickly get my hands on it. Searching for "bluetooth audio module" immediately brings up exactly what I wanted: 3 modules, and while the markings are absent from the chips... I'd bet my socks those are the JieLi AC6905a's that I'm looking for! So, now that I got it working, I had some more technical questions... The chip on this module is currently programmed to display "HW-Audio" as its pairing name, and there's various sounds that it plays to indicate "paired", "pause", "play", etc. If I'm going to be incorporating this chip into my future projects, I'd really like some control over what the name is, and how to change the sounds to whatever I want.

JL Chip Bluetooth Guide: What to Look for in 2024

Over the past year, JL (JieLi) Bluetooth chips have shifted from low-cost OEM components to widely recognized building blocks in budget TWS earbuds, portable speakers, and DIY audio modules — not because they’ve become premium, but because their ecosystem matured: firmware tools stabilized, datasheets became more accessible, and third-party replacement demand surged 12. If you’re sourcing a JL AC6921A for a speaker rebuild, replacing a failed AC695678N in a headset, or evaluating whether JL is viable for your next product design — this guide cuts through ambiguity. For most users, JL chips deliver predictable Bluetooth 5.0–5.3 audio with stable SBC/AAC support, moderate power efficiency, and straightforward PCB integration. Their chips combine ARM Cortex-M cores, Bluetooth radio, DSP, flash memory, and analog front-ends into single-package solutions — commonly labeled with series codes like AC69xx, AC7xxx, or AC23BP. Unlike QCC or BES chips, JL parts are frequently selected for cost-sensitive applications including sub-$25 earbuds, USB-C dongles, mono Bluetooth amplifiers, and white-label smart speakers 3. When you don’t need to overthink it: For a simple Bluetooth speaker board with 3.5mm input fallback, AC6921A is sufficient and cost-effective. Don’t default to datasheet headlines. Focus on what impacts real-world function: Firmware version & SDK lock-in: JL chips ship with locked bootloader.

Why Do So Many Bluetooth Speakers Use JL Chips?

If you’ve ever shopped for a Bluetooth speaker, you’ve probably seen dozens of brands and models. From well-known names to affordable off-brands, there’s one thing many of them have in common: their brains are powered by a chip from JieLi Technology, or “JL” for short. Easy to Build With: JL gives companies a complete “recipe” for building a speaker. They provide the chip plus all the instructions on how to design the circuit board, where to put the antenna, and more. This makes it almost foolproof for manufacturers to build a stable product without being experts, saving them a ton of time and headache. Strong Signal, No Static: Inside a speaker, there’s a lot of electrical noise that can cause Bluetooth to cut out or create static. This immediately cuts down the biggest cost for the speaker maker. An All-in-One Solution: This is the secret sauce. A single JL chip packs in almost everything needed: the Bluetooth, the audio processor, the power management, and even extra features like an FM radio or a slot for a memory card. JL chips are everywhere because they offer a winning combination: proven reliability, unbeatable value, and easy compatibility. For the companies making the speakers, JL is a no-brainer. It’s a low-risk, low-cost solution that gets a good product to market quickly. And for you, the customer, it often means you’re getting a reliable, feature-packed speaker without having to spend a fortune. Next time you’re looking at a Bluetooth speaker, there’s a good chance it’s running on JL—the tiny chip that powers so much of our portable music.

JL Chip currently mainly involves eight major fields (headphone chip, speaker chi, smart watch chip, video chip, health chip, IoT chip, smart toy chip, and smart travel chip), with more than 2,000 types of chip. , especially in the field of Bluetooth audio decoding, it has great advantages. It is usually a relatively high-end headphone or smart speaker chip. Such as in-ear, assistive listening, noise reduction, low latency, one-to-many application scenarios. JL7016C8 and JL7016G8 can be used as microphone solutions, JL7018F8 and JL7018G8 can be used as gaming headsets, etc. ... When it comes to audio products such as Bluetooth speakers and headphones, this is a key consideration or even the first factor. In particular, some projects that require third-party algorithms may be more concerned about this. The following is the RAM situation of Jerry series chip: ... JL chip usually have internal Flash inside. In addition to storing chip programs, it can also be used to store prompts, customized audio content, etc. Commonly used packages in Jerry include: SOP8, SOP16, SSOP24, QFN20, QFN32, QFN40 , LQFP48, can be selected according to the actual situation of your company. ... Because the chip is mainly positioned in the consumer and IOT markets, it needs to be carefully . You need to check the working temperature and humidity parameters of the chip . ... The higher the chip manufacturing process, the lower the performance and power consumption. jl found that the manufacturing process of mainstream chips has been upgraded to 40nm and 28nm.
