Senses when the user presses the physical power button. it8995e 128 datasheet
The host interface bridges the chip to the system’s PCH (Platform Controller Hub) via the LPC bus. The datasheet specifies the LCLK (33 MHz) and the 4-bit data lines (LAD0-3). This is where the BIOS sends commands to configure the Super I/O.
. These are often interchangeable if the motherboard schematic specifies "IT8995E-128 CX" or "DX". Chipset Elektronik Core Functions & Applications System Management:
This article provides a deep dive into the IT8995E-128 features, technical specifications, and application, based on key datasheet information. 1. Overview of the IT8995E-128 Embedded Controller Senses when the user presses the physical power button
IT8995E-128 highly integrated Embedded Controller (EC) and Super I/O (SIO) chipset manufactured by
This controller is widely integrated into notebook motherboards (such as the X543U and X705UB series). You can find these chips and related technical documentation through retailers and electronic component hubs like IC-Components , Atom Bilgisayar , and Worldway Electronics . IT8995E-128/CXA ITE - IC Components
If you are searching for the term you are likely working with a modern laptop motherboard—probably from ASUS—and you need to understand the embedded controller (EC) at its heart. The ITE IT8995E-128 is a high‑performance, programmable Super I/O (SIO) and Embedded Controller chip that acts as the “command center” for core system functions, from power sequencing to keyboard control and thermal management. However, unlike many common chips, the full IT8995E-128 datasheet is not publicly released by the manufacturer . This guide consolidates all publicly available, verified information from repair forums, product listings, and hardware teardowns to serve as a practical reference for technicians, engineers, and enthusiasts. This is where the BIOS sends commands to
The chip provides which can be individually configured as inputs or outputs via software. In a laptop, these are used for tasks such as reading the lid switch state, controlling LEDs, or interfacing with simple sensors.
