It8995e 128 Datasheet Updated

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 supports the standard, a robust protocol for negotiating power contracts between a source (like a charger) and a sink (the laptop). This allows the device to request and deliver up to 100W of power, enabling fast charging and the ability to power a wide range of peripherals directly through the USB-C port.

Analog power supply for the internal Analog-to-Digital Converters (ADC). GND / AGND: Digital and analog ground reference lines. Communication Interfaces

Missing keys or completely unresponsive input devices often point to localized damage near the EC's GPIO pins.

The chip is equipped with built-in, on-die protection features to safeguard the system against electrical faults: it8995e 128 datasheet

The includes a reference design for a typical motherboard. Below is a simplified schematic partial:

The IT8995E-128 excels in industrial and embedded applications due to its wide temperature range and high GPIO count.

: CXA and CXS revisions are generally considered interchangeable in motherboard schematics. Quality & Safety Features Compliance : RoHS compliant for hazardous materials.

Multi-channel 10-bit ADC used for monitoring system voltages, battery charge levels, and thermal thermistors. The IT8995E-128 is a fundamental component in system

: Widely encountered as IT8995E-128 CX , with variant suffixes like CXA, CXS, and DXA .

Because the IT8995E-128 contains internal embedded flash memory (or directly controls an adjacent private SPI ROM), replacing a dead chip requires more than just soldering. A blank, factory-new IT8995E-128 will not boot a laptop. Flashing Methods

Ensure the WRST# pin is at 3.3V. If it is stuck at 0V, the chip will remain in a permanent reset state. High Current Draw / Heating Chip

Use a multimeter to check the following (refer to boardview files or schematics for exact pin numbers): This allows the device to request and deliver

Please refer to the official ITE datasheet for exact tolerances. Below are standard architectural limitations for this class of I/O controllers. Minimum Value Maximum Value Input Pin Voltage (5V Tolerant) Input Pin Voltage (3.3V Standard) VCC + 0.3 V Storage Temperature Ambient Operating Temperature Conclusion

Because the IT8995E-128 contains internal flash memory, replacing a damaged chip with a brand-new blank one will not fix a motherboard. The new chip must be programmed with the specific binary file (.BIN or .HEX) matched to the laptop's exact motherboard model and revision.

IC-Components provides safety features and quality certification details.

Consequently, rely on Linux kernel drivers and proprietary Windows tools to infer the chip’s behaviour. The Linux kernel does contain basic support for this chip (via the “ite” driver), but full functionality (e.g., fan speed monitoring) is often incomplete.
