It8995e 128 Datasheet ◎ «DELUXE»
When a brand-new IT8995E-128 chip is soldered onto a motherboard, it usually attempts to fetch its operation payload directly from the main motherboard BIOS chip upon receiving standby power ( +3VALW ). However, if the auto-synchronization cycle fails, the laptop will experience a "No Power / No Post" fault state.
Because the IT8995E-128 utilizes a 128-pin LQFP package, pins are grouped logically by functionality. Below are the critical pin categories required for motherboard troubleshooting. 1. Power and Ground Pins

Note: If replacing this chip, ensure you have the correct firmware, as it may not automatically pull code from the BIOS upon assembly. IT8995E-128/CXA ITE - IC Components
Some motherboard designs (notably certain ASUS boards) feature a bootloader circuit that can automatically grab the EC firmware from the main BIOS chip upon the first power-up. If the motherboard supports this, a blank IT8995E can be soldered on directly without pre-programming. 6. Electrical Characteristics (Absolute Maximum Ratings)
