Datasheet for the ITE IT8512E-F embedded controller, a 1.99 MB PDF. Chips of this family serve as the keyboard and embedded controller on many notebook motherboards, handling power sequencing, battery charging communication, keyboard scanning and fan control. The document describes the pin functions, power domains, the SPI flash interface and register details. Technicians consult it to check EC supply pins and the standby clock, and to trace the power button and power-good signals when a board will not power on.
