I'm working on reverse engineering a PCB (no documentation by manufacturer). I've identified all the other chips on this board but this one refuses to give up any google-able info. Are there any resources that can help me identify what kind of chip this is?
______________ D1 --|O ATH 330 |--? D2 --| |--Vss Vss--| 50?L 8 |--D4 GND--| 3U49758 |--D5 --------------
D1, D2, D3 and D4 pins are connected to a 5x2 grid of test points which I've soldered a header into. Vss is connected to the Vss of a PIC32MX695F512H microcontroller.
Let me know if I can provide additional info to assist this process.
