I have an electronic part that have to know more about it. Anyway, I cannot find its datasheet or even I don't what is this part and its function. If you give me any information about it such as datasheet, the company website or etc., I would appreciate it.
here is a picture of the part I attached. It seems that its part number is "6903 1406"
Currently we just see the "6903"...we could do an internet search, but most probably you did this already.
Did you read other post requesting for IC informations?
As with the other posts we need some informations like
* application (we don't know whther this is from a microwave oven or an E-bike)
* package size
* pin count (it's impossible with your picture...)
* wiring / traces (which ones are wide, narrow, connected to GND...)
* and so on

- Its application is in ultrasonic water meters. Using some multiplexers and one comparator, it is connected to the ultrasound sensors.
- Its size is 5mm*5mm
- Its package is QFN32 (32 pins)
I attached another picture in which the tracks are visible.
It could be almost anything. That isn't a recognized part number and although it might be a generic device, probably has custom programming inside it which can only be done during manufacture. The numbers are probably a custom 'house' code for stock control rather than identifying a device you could buy off the shelf.
