V16C6448AC datasheet, a 473 KB PDF that appears to be a sibling of the AF-suffixed document covering the same base part. The suffix letters often denote package, speed grade or revision, but the name does not explain them, so check the ordering table inside. Use it for pinouts, absolute maximum ratings, timing and package dimensions when diagnosing or replacing the chip. Verify the exact suffix stamped on the component matches before swapping parts or relying on specific timing figures.
