Understanding the KB926QF Datasheet: An In-Depth Look at ENE’s Embedded Controller

What is the KB926QF?

The KB926QF is a Keyboard Controller / Super I/O chip. It is responsible for handling the matrix of the keyboard, managing mouse functions (PS/2 interface), and often communicating with the system via the LPC (Low Pin Count) bus. kb926qf datasheet

Serial Ports (UART A and B)

• SOUTA, SIN A, RTSA, CTSA, DCDA, DTRA, DSR A, RIA (and similarly for UART B).
• These pins connect directly to RS-232 transceivers (e.g., MAX232) for COM ports.

The KB926QF has several revisions (suffixes), and they are not always 100% interchangeable without modification: Cher3 2 (Ver 1.7) en | PDF | Mosfet | Bios - Scribd Understanding the KB926QF Datasheet: An In-Depth Look at

Hardware Monitor

• VIN0 – VIN5: Analog voltage inputs (e.g., +12V, +5V, Vcore, VBAT)
• TEMP1, TEMP2: Inputs for thermistors or thermal diodes.
• FANIN1, FANIN2, FANIN3: Tachometer inputs for fan speed monitoring.
• FANPWM1, FANPWM2: Fan speed control outputs.
