IT8995E-128/CX, IT8995E-128/CXA, and IT8995E-128/DXA.
Designed for industrial automation and advanced computing modules where continuous, dependable operation is required. Motherboard Integration:
The of the board (e.g., drawing 0.01A on the bench power supply, short circuit on a 3V rail).
If the laptop shows no signs of life, check the basic requirements of the IT8995E-128: Verify that is present on the standby power pins. Check the crystal oscillator or internal clock generation. it8995e 128 datasheet
The stands as a testament to the high level of integration in modern laptop design. It is a sophisticated, programmable embedded controller that merges legacy Super I/O functions with advanced features like USB Power Delivery 3.0.
Keyboard Scan Input and Output lines map the multi-point layout of internal laptop keys. ADC[7:0] , DAC
: The EC_RST# pin transitions from low to high, allowing the internal micro-controller to boot. IT8995E-128/CX, IT8995E-128/CXA, and IT8995E-128/DXA
: Supply 3.3V to the motherboard using a laboratory DC power supply (do not turn on the laptop; standby voltage must be present).
The is an embedded multi-controller (EC) manufactured by ITE Tech. Inc. , commonly used in laptops and personal electronics for power management, keyboard control, and system monitoring. It is a high-performance integrated circuit (IC) known for balancing power efficiency with complex task handling. Technical Overview
Monitors the physical power button. When pressed, it triggers a chain reaction, signaling the power ICs to generate the necessary voltage rails (+3VALW, +5VALW, VCCRTC, etc.). If the laptop shows no signs of life,
LPC (Low Pin Count) or eSPI (Enhanced Serial Peripheral Interface) standard system bus execution.
: Features built-in electrostatic discharge (ESD) protection and overheating safeguards to ensure long-term reliability. Applications
