Laptop power management (DC/DC control), keyboard interface, and BIOS communication. ariat-tech.com Datasheet Resources
The chip relies on firmware code stored either in its embedded flash array or an adjacent SPI ROM chip. A proper datasheet schematic delineates the SHBM (Shared Memory) configuration or private SPI bus lines. This is vital for programming blank replacement chips via external hardware like an RT809H or SVOD programmer. 3. Power-Up Reset Sequence Diagram wpce773la0dg datasheet pdf better
