Do you recognize this chip?
« on: December 19, 2021, 01:07:04 pm »
Hi,
I think it it may be an Application processor , Do you know the manufacturer and datasheet? or it's something else?

Would be nice to know  in what it is used, a car radio ? Stereo system ?

The bm8563 is a RTC, so this chip seems to drive an lcd,  if i guess the long connector traces going to the ic ?? 

And the dosilicon chip is an i2c potentiometer

Seems a rebranded chip to hide the real numbers ??

As already stated, that looks like a OEM marking as no date or batch codes. It would really help your cause if you included details of the equipment that this PCB resides in and a larger view of the PCB as that can assist in identifying function and possible candidates. Why you think this IC is the cause of your issues is also helpful information.

I don't know, but here's a fun list of crystal frequencies and their uses

https://en.wikipedia.org/wiki/Crystal_oscillator_frequencies

Although that crystal seems to be related to circuits not shown. But who knows!

24.0 MHz is often used for USB.

It's used inside a home Iphone monitor, and I think it's connected to the LCD too.
