I'm trying to draw out a schematic by probing a PCB for a motion-sensing LED light, and I see this 14-pin (SOT-14?) chip shown below. The manufacturer seems to be MicrOne, but their page for the ME9101 chip doesn't match, showing that it has 21 GPIO pins while this chip only has 14 pins.
This chip seems to be connected to 2 other subcircuits -- one signal from a chip that detects touch on a touchpad, and another to a passive IR sensor. I'm also not sure if the symbol right next to the 9 is actually a 1, 7, or other symbol. I assume its purpose is a microcontroller but would appreciate any tips on identifying this chip. I've read another answer on how to begin identifying chips, but am still relatively new -- I'm not sure what to search for aside from the markings I see + "microcontroller". Thanks!
