JieLi Technology - Chips Delight the World.

JieLi (杰理, “π”, “JL”, “Jerry”

“jelly”, 光) is a company that was based in year 2010 in the ZhuHai city of Guangdong province, China.

Their chips can be found in various cheap MP3 players, Bluetooth speakers, Bluetooth/MP3 modules, dash cams and so on. (along with other companies like “Jianrong” Appotech/Buildwin, “AB” Bluetrum, MVSilicon, Beken, RDA, etc.)

Chips can be identified as JieLi ones by them having a slanted “JL”/”π” logo, and a misleading/nonsense marking that doesn’t tell the real chip name right away, like “AB1526CG3X1F.1-82E” (AC1082), “AB1819CK1Y11.1-87” (AC1187), “AC1631D97294-04A” (AC5204A), “AC20BP05193-65A4” (AC6965A), to name a few.

Sometimes their chips are rebadged, for instance: “TD5161A” is the AC6965A, “MH-M18” is AC6925C (recently it’s AC6925D).

Although it seems like they now do print the actual chip names on some recent chip series like JL697N, JL700N, etc.

Here is some information on what the markings actually mean.
