Features an integrated 128KB programmable eFlash (Embedded Flash) memory. This storage holds the specific EC firmware necessary to execute power sequences and peripheral control.
The IT8995E‑128 is heavily used in from the mid‑2010s to early 2020s. Based on repair logs and motherboard component lists, here are confirmed models that contain this EC:
: Fully lead-free and RoHS compliant . Core Functional Responsibilities
Interfaces with the laptop keyboard and touchpad. it8995e 128 datasheet
The IT8995E-128 has a unique relationship with the main system BIOS. A modern laptop contains two separate flash memory chips:
The data suggests there are two physical variants of this controller. The QFN-40 (6x6mm) variant likely contains only the USB Power Delivery controller and power management IC, while the TQFP-128 variant is the full-featured Embedded Controller found on most motherboards. The "128" in the name often refers to the pin count of the larger package.
All four conditions are required for the EC to execute its firmware. Based on repair logs and motherboard component lists,
Battery charge path negotiation and SMBus battery telemetry verification 2. Keyboard & Human Interface Device (HID) Core
The IT8995E-128 is a highly integrated, multi-function Embedded Controller (EC) developed by ITE Tech Inc. It is primarily designed for modern laptop motherboards, netbooks, and small form factor computing systems. Operating as the "always-on" brain of a computer, this integrated circuit (IC) manages low-level hardware operations long before the main CPU powers on.
3.3V Standby Power. This rail must be active as soon as the power adapter is plugged in. A modern laptop contains two separate flash memory
Forwards the power button signal to the PCH to initiate the main boot sequence.
Housed in an industrial LQFP-128 (Low Profile Quad Flat Package) / TQFP-128 configuration featuring 128 leads. This compact packaging optimizes PCB surface area while offering immense multi-channel input/output flexibility.
The reset pin must be pulled high (3.3V) for the chip to boot.
It reads temperatures from thermal sensors and dynamically adjusts Pulse Width Modulation (PWM) fan speeds to prevent overheating.
If you lack professional KBC programming equipment, consider sourcing components from suppliers that offer pre-programming services based on your specific laptop motherboard model number.
