PDF databook for the AMD Polaris 12 XL GPU, compressed in a 1.31 MB RAR. The reference explains the chip's pinout, power domains, memory interface and electrical requirements, which matters when diagnosing entry-level graphics cards or laptop GPU circuits built around it. Use it to check which rails feed the core and memory, follow signal paths and confirm strap settings. As with other databooks, it covers the processor only, so verify the XL variant is fitted and use a board-specific schematic alongside it.
