: Includes dedicated fan controllers and PWM (Pulse Width Modulation) outputs to regulate system temperature based on thermal sensor data.

: Implements a Shared-ROM architecture . This allows the EC firmware and the system BIOS to reside within a single SPI flash memory chip. Key Functional Responsibilities kb926qf datasheet

: Primarily functions as an i8042-compatible keyboard controller , managing the keyboard matrix and PS/2 interface for touchpads. : Includes dedicated fan controllers and PWM (Pulse

: 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 . Key Functional Responsibilities : Primarily functions as an

: Supports SIRQ for IRQ1 (Keyboard) and IRQ12 (Mouse), as well as SCI/SMI# for power management events.

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.
