Does anybody know what this IC is?

$begingroup$


I tried different search keywords combinations, but I couldn’t find a datasheet, nor a hint of what this IC could be. Maybe someone who’s familiar with it could give me a clue. APT619AP 0609A BJC6124
The IC is on a board that was part of the control panel of a home theater. The options were volume up and down, surround 2.1 or 5.1 and mute. The brand was National Star, as far as I can recall. Thanks in advance.

    Can you add a photo of the other side of the board -- this might be a microcontroller in 18-DIP package. If you could determine which pins are ground, logic power supply, and i/o that would help. There's no visible manufacturer logo, only the top mark "APT619AP" and date/lot code "0609A BJC6124". Some IC manufacturers have a database of topmark to part number, but there's still a lot of guesswork.

    @Damián - Hi, From the photos, I'll just make two short comments. You haven't asked this as a repair question (it's difficult to make them on-topic here, so that's good!) but assuming you believe there's a fault on that board: (a) There's very questionable soldering in several places including, but not only, where C1 and IR1 used to be (and possible solder bridges in both of those places). (b) The fault on the board might be elsewhere e.g. power problems, which could cause the (suspected MCU, per Spehro's answer) IC to misbehave. I would not start by trying to replace the IC. Good luck!

$begingroup$

Judging by the ceramic resonator and load capacitors connected to pins 15 and 16, it's almost surely a microcontroller with a custom program in OTP or flash memory. And typically the program memory is read-protected for the security of the manufacturer's firmware.



So more than likely it's not the sort of thing you'll be able to buy from other sources than the original, such as a used board or repair part.
