Kb926qf Datasheet |top| May 2026

The ENE KB926QF is a highly integrated Embedded Controller (EC) specifically designed for notebook and laptop platforms. It acts as the "Keyboard Controller" (KBC) and manages critical low-level system functions. Key Technical Functions

• VCC (Power Supply): Usually operates at 3.3V or 5V rails (depending on the specific internal block).
• Troubleshooting Tip: Before replacing the chip, check the surrounding capacitors and resistors for the power pins. If the chip isn't receiving its rated voltage, the issue is likely the power regulation circuit, not the chip itself.

4. Keyboard Matrix Scan

• Rows/Columns: Usually 8x20 or similar. The datasheet shows which pins are KSOn (scan out) and KSIn (scan in).
• Useful for: Fixing non-working keys or repurposing keyboard controller pins.

Interfaces: Supports LPC (Low Pin Count), PS/2 for keyboards/touchpads, and SMBus. kb926qf datasheet

• Serial ports (UARTs: COM1, COM2)
• Parallel port (LPT/Printer port)
• Floppy disk controller (FDC)
• Keyboard and mouse controller (PS/2 ports)

sequence, it is often the first suspect when a laptop fails to trigger after pressing the power button. Availability The ENE KB926QF is a highly integrated Embedded
