I recently purchased a ShinePine Bluetooth Karaoke microphone from Amazon UK. It provides Bluetooth, echo, pitch changer, mic input, LEDS, Card Reader, control switches as possibly in the same chip. Made in China. I am trying to identify the chip. The 24MHz crystal on on the left side of the image, the Bluetooth PCB antenna above the IC.

Bluetooth chip

The part number search of AC208P in Google brought up the very similar but not identical Microchip IS2083 Bluetooth Stereo Audio SoC https://www.microchip.com/wwwproducts/en/IS2083, but in a different package. Is the chip in my image a clone of the Microchip version please?

It has nothing to do with Microchip... the part you link is apparently only available as BGA.

The part is from a manufacturer called Zuhai Jie Li. See this: Indentifying a JL chip in a Bluetooth. It might be a proprietary part.
