Hi
I have come across a few MCU with just random letters inscribed on the chip. No mention that's it's r7f7. Searching the inscriptions on the net didn't reveal anything.
However searching the airbag module number revealed it was an r7f MCU.
Does anyone know how to relate these seemingly random inscriptions to the appropriate chip? Is there a list from renesas? How did cg 70 or obdstar p50 people find out what those chips were.
