It8995e 128 Datasheet Jun 2026

The IT8995E-128 is a fundamental component in system architecture, bridging the gap between mechanical user inputs, power hardware, and the main operating system. For deep hardware repairs, acquiring the exact schematic diagram of the motherboard alongside the IT8995E-128 pinout details is crucial for tracing faults accurately and ensuring successful board-level repair.

It manages the keyboard matrix, touchpad, and other user input devices, interfacing directly with the system over the PS/2 or embedded controller protocols. 4. Programming and Repair (IT8995E-128/CXA)

If you're repairing a motherboard, I can help you identify the or suggest programming tools compatible with the ITE IT8995E-128. IT8995E-128/CXA ITE - IC Components it8995e 128 datasheet

A responsible engineer must check the "Absolute Maximum Ratings" section in the official datasheet. Based on ITE’s typical specs:

setup, allowing for extensive Input/Output (I/O) flexibility. Package Type: Typically found in a QFP (Quad Flat Package) The IT8995E-128 is a fundamental component in system

When industrial PCs need parallel printers, legacy serial devices (RS-232), or PS/2 keyboards, designers integrate the IT8995E 128. The datasheet provides the register maps to initialize these ports via the BIOS.

The 128 pins of the LQFP package are clustered into specialized hardware subsystems: Pin Subsystem Group Primary Functions & Signals Description VCC , VSTBY , AVCC , GND Direct power supply connection pins. They distribute standby power and analog filtering blocks. System Bus Interface LAD[3:0] , LFRAME# , SERIRQ Based on ITE’s typical specs: setup, allowing for

The IT8995E-128/CXA acts as an intermediary between the motherboard power rails, sensors, and the main operating system. A. Power Management

The CXA variant is commonly used in laptop repair to resolve power-on failure (no-boot) issues. 5. Summary Table: IT8995E-128 Specifications Specification Manufacturer ITE Tech Inc. Model IT8995E-128/CXA Package LQFP-128 (128-pin) Memory 128KB Embedded Flash Memory Interfaces LPC, SMBus, I2C, PS/2, GPIO Core Functions Power Management, Thermal Control, Keyboard Control 6. Conclusion

The suffix “128” refers to the LQFP-128 package type. ITE also produces versions like IT8995E-100 (100-pin LQFP) and IT8995E-176, but the -128 is the most common for mid-range motherboards.
