It8995e 128 Datasheet

IT8995E-128 is a specialized integrated circuit (IC) manufactured by ITE Tech. Inc. , primarily utilized as an Embedded Controller (EC)

These chips are almost exclusively found on laptop and desktop computer motherboards. They act as the "brain" behind the main CPU, handling low-level tasks like power management, keyboard scanning, and fan control.

The controller is housed in a 128-pin LQFP (Low-profile Quad Flat Package), which allows for extensive input/output (I/O) flexibility. it8995e 128 datasheet
