It8995e 128 Datasheet -

ITE / ITE Tech. (ITE Technology / ITE Tech. Inc.) — commonly sold as an SIO/KBC/IO-controller family device used on laptop and embedded motherboards.

Technicians can write the appropriate firmware file to the 128KB eFlash using specialized motherboard repair programmers (such as the RT809H, Vertyanov, or SVOD programmers) directly through the keyboard matrix ribbon connector interface or dedicated I2C debug headers.

: Monitoring temperature sensors and adjusting fan speeds to prevent your laptop from melting.

: Lid switch input. A low signal indicates the laptop lid is closed, prompting the system to enter sleep mode.

Monitors battery voltage, thermistors, and dynamically handles analog control signals. SMCLK[2:0] , SMDAT[2:0]

: Use the programmer software to read the existing 128KB binary file (for backup), erase the chip memory, and write the verified clean dump file. 5. Diagnostic and Troubleshooting Reference ITE / ITE Tech

The IT8995E-128 belongs to ITE’s line of Super I/O and Embedded Controller chips. It utilizes an internal RISC or micro-controller core paired with embedded flash memory to execute complex system management firmware. Key Specifications ITE Tech Inc.

The is a highly integrated, programmable Embedded Controller (EC) and Super I/O chip. It serves as the central nervous system for low-level hardware management in a computer, primarily found in high-volume laptop designs from manufacturers like ASUS .

If you measure 0V on pins , 4 (PM_SUSC#) , and 5 (INT_SERIRQ) while the power button ( PWR_SW# ) is functioning and the EC has power, it strongly indicates a corrupted EC firmware or a faulty chip. Technicians can write the appropriate firmware file to

For technicians and DIY repairers, the IT8995E-128 is widely available from electronics suppliers.

The EC requires a standby voltage rail to monitor the power button before the system turns on.

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

The device communicates continuously with the Smart Battery System (SBS) over an I2C or SMBus network to monitor state-of-charge, dictate charge currents, and prevent overvoltage or overcurrent damage. Programming & Motherboard Repair Insights
