Contains an internal microcontroller core (often based on an 8051 or RISC architecture) running proprietary firmware stored in an onboard or external SPI flash memory chip.
Compatible with industry-standard protocols including: LPC (Low Pin Count). SMBus (System Management Bus). I2C (Inter-Integrated Circuit). PS/2 interfaces.
This controller is widely integrated into notebook motherboards (such as the X543U and X705UB series). You can find these chips and related technical documentation through retailers and electronic component hubs like IC-Components , Atom Bilgisayar , and Worldway Electronics . IT8995E-128/CXA ITE - IC Components it8995e 128 datasheet
The IT8295E chip can be used in various applications, including:
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. Contains an internal microcontroller core (often based on
Deep Dive: Deciphering the ITE IT8995E-128 Datasheet If you’ve ever cracked open a modern notebook—especially an ASUS or similar laptop—you’ve likely spotted a square, multi-legged chip labeled . For repair technicians and hardware enthusiasts, this "Super I/O" or Embedded Controller (EC) is the gatekeeper of the motherboard.

: Utilizes the Low Pin Count (LPC) or Enhanced Serial Peripheral Interface (eSPI) to communicate with the chipset.
Battery state-of-charge, voltage, and health via the SMBus/I2C protocol.
Certain keys, rows, or the entire keyboard fail to respond, despite replacing the keyboard hardware itself.
The internal oscillator stabilizes, and WRST# goes high.
