integrated circuit - JL (or maybe something else) misterious branded IC's




Edit 12/31/2019: Thanks to Mariano Dupont:


Found it: Zhuhai Jieli Technology zh-jieli.com




Take a look at this example of an IC found on a circuit board:




JL branded ic




Brand is found on many PCB's of Chinese/India manufacturers of different kind of devices, mostly consumer based.


For example, there are many printed logo's on IC's listed on this site, however you cannot find this JL (or sort of italic pi?) logo, unable to find it anywhere. Also when this logo is on an IC and searching for the part-number/IC model number, always lead to a dead end, I am never able to find a datasheet.



So what is this misterious brand, is it actually a brand, what's the origin and actual name of the manufacturer? And is the part-number/IC model number really a description of what it is or just a random number?



Answer



I remember this logo. Don't ask me where I know it from. A bit digging showed that we had a similar request for this chip already:


Help for identifying pinout of unknown mp3 chip


Manufacturer is probably called "Jerry" or "Jay Management". Probably there simply is no english name for the manufacturer.


Maybe some Chinese speaking member can chime in and use some Chinese search engine fu to find out more.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
