Internal 128KB programmable eFlash (Embedded Flash)
The 3.3V Always-On regulator activates, supplying power to the VSTB pins of the IT8995E.
3.3V Standby Power. This rail must be active as soon as the power adapter is plugged in.

IT8995E-128 Datasheet: Technical Overview, Pinout, and Programming Guide
As a "Super I/O" or Embedded Controller, the chip serves as the hardware supervisor for the following systems:
If you are troubleshooting a dead laptop and the IT8995E‑128 has all four essential conditions present— VCC (3.3V) , EC_RST# (3.3V) , 32 kHz clock , and proper BIOS communication —but the laptop still does not turn on, the EC itself (or its firmware) is likely defective. Internal 128KB programmable eFlash (Embedded Flash) The 3
The is a high-performance Embedded Controller (EC) and Keyboard Controller (KBC) designed primarily for notebook motherboards. It plays a critical role in managing low-level hardware functions, including power sequencing, thermal monitoring, and peripheral interfaces. Core Technical Specifications
IT8995E-128/CX, IT8995E-128/CXA, and IT8995E-128/DXA.
: Ground the programmer to the motherboard. Connect the FFC between the programmer and the laptop's keyboard matrix slot. : Includes 128KB of internal Flash Memory ,
: Output from the EC to the PCH, mirroring the power button press to wake the chipset.
Unlike older Super I/O chips that read external BIOS chips for instructions, the IT8995E-128 contains internal flash memory that must be explicitly programmed. Required Tools
