What 8-pin MCU might this be ?
« on: May 02, 2024, 11:11:46 am »
I have an RGB LED strip controller, that had an IR remote control. And the label of the 8-pin SIOC MCU was etched off. There's an EEprom next to it, so I would assume they would use the default I2C pins on the MCU, with the EEPROM.

But I'm just wondering what might have this pin out. I barely know ATMEL MCU's, but this might be a PIC type ?

1-Vcc
2-SCL
3-SDA
4,5,6,7, GPIO
8-GND

Most likely a cheap Chinese job like the Padauk PMS150- these are be pin-compatible with PIC12

Mike's Electric Stuff: High voltage, vintage electronics etc.
Day Job: Mostly LEDs

I should leave it alone for now, I'd probably have to download a bunch of other software/etc. I just wanted to see what the program on it might look like. Somewhere I have the remote too. The LED's were thrown out years ago.

But yeah I could just make some strings of LED's for it, and it should all still work. And I want to see how the remote works and sends data. But I've never tried anything with a PIC before.

Chances are this is a Padauk. In which case, nothing was etched off, they just tend to be labeled on the bottom side. You'd have to desolder it to check ...

If this is some cheap Chinese LED controller, then most of all this is some kind of Chinese controller probably something 8051 based with one-time programable memory, they don't use branded MCU in a cheap mass production devices due to higher price. Even if some device contains branded MCU, they will replace it with more cheap Chinese one for economy
