: Supports SIRQ for IRQ1 (Keyboard) and IRQ12 (Mouse), as well as SCI/SMI# for power management events.
: Standard 128-pin LQFP (Low-profile Quad Flat Package), designed for surface-mount technology (SMT) and hot-air rework.
The 128-pin layout is densely packed with specialized signals. Notable pins and interfaces found in documentation from DatasheetCafe and Scribd include:
: Requires specific voltage rails like EC_AVCC for its internal analog components. Common Variants and Repairs
The chip exists in several versions, such as , C1 , D2 , and D3 . Technicians often seek these datasheets when troubleshooting "no power" states, keyboard failures, or charging issues. Because the IC is highly customized via firmware, replacing it often requires ensuring the firmware in the shared SPI flash is compatible with the specific chip revision.

The is a highly versatile Embedded Controller (EC) , commonly referred to as a Super I/O chip, manufactured by ENE Technology . Predominantly found in laptop and notebook motherboards, this IC acts as the system's "sub-brain," managing low-level hardware operations that occur even before the main CPU fully boots. Core Technical Specifications
: Includes dedicated fan controllers and PWM (Pulse Width Modulation) outputs to regulate system temperature based on thermal sensor data.
: Primarily functions as an i8042-compatible keyboard controller , managing the keyboard matrix and PS/2 interface for touchpads.
According to the technical parameters from Jotrin Electronics , the KB926QF features:
: Features integrated A/D (Analog-to-Digital) and D/A (Digital-to-Analog) converters to monitor voltages and signals like BATT_TEMP and ADP_I .
