I have an integrated circuit in the form as a DIN chip, and I have no clue what it is. I have tried searching for the markings on the chip, which are as follows:

Top: HDJ2100-393 937GA1925463B2WW

Bottom: TAIWAN 937GA1925463B2WW

It is a 40-pin chip. I found two of these inside of an old CD mixer. It is a Numark CD-MIX 1, and it was on what appeared to be the display system, as there were two near where the LCDs were. All I could find for a manual is the quickstart guide here, but I don't have the manual because it was basically in a giant bin of audio equipment.

Could someone tell me what this is or direct me on how to figure it out?

  • \$\begingroup\$ Did you find this on the beach in a washed up submarine or in a broken hi-fi? The context would be quite important when trying to identify a chip. Hit the edit link to add in the details. Did you mean DIP, DIL or DIN? (If DIN, what does it stand for?) \$\endgroup\$ – Transistor Apr 27 '20 at 17:19
  • \$\begingroup\$ You got it - old CD mixer. I meant dual in-line, I see it referred to as DIN. \$\endgroup\$ – coresdev Apr 27 '20 at 17:20

    \$\begingroup\$ I'd say your chances are slim and that that's a custom display driver chip for that range of products. Maybe someone will have a clue. \$\endgroup\$ – Transistor Apr 27 '20 at 17:32

More often than not, such ICs are custom made for a specific purpose. Their datasheets and other such information is usually private, and not publicly available.

I found a device which fits your description (called Inter-m CDC-2050), and which includes this IC. I couldn't find any datasheet for it, though.
