It8995e 128 Datasheet Jun 2026

: Features an internal RISC architecture optimized for real-time control tasks.

While it may sometimes auto-sync from the main BIOS, it often requires manual programming via the I2C or keyboard connector interface to initiate the system cycle.

: Handles temperature sensors and fan speed control.

Technicians use specialized hardware programmers (such as the SVOD, RT809H, or Vertyanov JIG programmer) connected directly to the motherboard's keyboard matrix connector via a ribbon cable. it8995e 128 datasheet

: Housed in a 128-pin LQFP (Low-profile Quad Flat Package), providing high I/O flexibility and efficient heat dissipation.

It controls the state machine of the motherboard, transitioning the system through power states (S5/Soft Off, S3/Sleep, S0/Fully On) by turning on specific voltage regulators in a precise order.

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 : Features an internal RISC architecture optimized for

Supports various system wake-up functions for power management. Technical Details Manufacturer ITE Tech. Inc. Interface Typically interfaces via LPC or eSPI bus Operating Voltage Generally supports 1.8V / 3.3V logic (standard for ITE ECs) Programmability

All four conditions are required for the EC to execute its firmware.

If you want, I can:

Represent architectural structural revisions. Always verify pin configurations against your motherboard schematic diagram before swapping a CX chip out for a DX variant to ensure step-up voltage alignments match perfectly. Common Failure Symptoms and Diagnostic Checklist

The IT8995E‑128 is heavily used in from the mid‑2010s to early 2020s. Based on repair logs and motherboard component lists, here are confirmed models that contain this EC:

128 KB of internal embedded flash memory (indicated by the "-128" suffix) used to store the EC firmware (often called the EC BIOS). 2. Primary Functions of the IT8995E-128 ITE IT8995E-128 is a specialized Keyboard Controller (KBC)
