It8995e | 128 Datasheet

ITE IT8995E-128 is a specialized Keyboard Controller (KBC) or "multi-controller" primarily used in laptop motherboards (such as the ASUS X543U) to manage low-level system functions. While a single consolidated datasheet is notoriously difficult to find publicly, it belongs to a family of ITE chips known for their robustness in enterprise and personal electronics. Key Specifications & Features

The IT8995E-128 is designed with a specific focus on low power consumption and high integration to reduce the physical footprint on a motherboard. it8995e 128 datasheet

• "What is the current battery percentage?"
• "What is the current fan speed?"
• "Is the lid closed or open?"

Integration Notes

• Requires external PMIC or discrete power components for full battery charging and power-rail management.
• Firmware development typically uses vendor-provided SDKs or toolchains; consult manufacturer application notes for GPIO mapping, interrupt routing, and power-sequencing examples.
• Careful layout recommended for ADC inputs, thermistor routing, and high-current routing for power-control lines.
• Include ESD protection and proper decoupling on power rails and I/O lines.

Repair Note: CXA and CXS revisions are generally considered interchangeable in motherboard schematics. Quality & Safety Features Compliance: RoHS compliant for hazardous materials. ITE IT8995E-128 is a specialized Keyboard Controller (KBC)
