The IT8995E-128 is suitable for a wide range of applications, including:
I’m unable to directly retrieve or generate the full PDF datasheet for “IT8995E 128” (likely the – a Super I/O controller for embedded/industrial motherboards). Datasheets are copyrighted and distribution-restricted by the manufacturer (ITE Tech. Inc.).
The 128 pins of the LQFP package are clustered into specialized hardware subsystems: Pin Subsystem Group Primary Functions & Signals Description VCC , VSTBY , AVCC , GND Direct power supply connection pins. They distribute standby power and analog filtering blocks. System Bus Interface LAD[3:0] , LFRAME# , SERIRQ it8995e 128 datasheet
The reset pin must be pulled high (3.3V) for the chip to boot.
: Utilizes the Low Pin Count (LPC) or Enhanced Serial Peripheral Interface (eSPI) to communicate with the chipset. The IT8995E-128 is suitable for a wide range
The is a high-performance Embedded Controller (EC) and Keyboard Controller (KBC) designed by ITE Technology, primarily used in laptop motherboards (e.g., ASUS models like X510U, X543U).

Common Revisions & Compatibility Main Model : IT8995E-128. Revisions : Often seen as CXA or CXS .
Supports the Intel Low Pin Count (LPC) interface as well as the newer Enhanced Serial Peripheral Interface (eSPI) bus used in modern chipsets. Key Hardware Features The 128 pins of the LQFP package are
The IT8995E-128 is a highly integrated and versatile embedded controller that offers a rich set of peripherals, low power consumption, and a compact package. Its robust design and wide operating temperature range make it suitable for harsh industrial environments. With its ARM Cortex-M4 core and ample memory, the IT8995E-128 is an ideal choice for a wide range of applications, from industrial control and automation to IoT devices.
128 KB of on-chip programmable flash memory (indicated by the "-128" suffix) used to store the EC firmware.
If a motherboard fails to post or display a signal after a chip swap (e.g., full fan spin but a completely blank screen), the EC may require manual programming.
