W83667HG-B(FA5B35 E)

Specialized Overview

The W83667HG-B is a Super I/O controller manufactured by Nuvoton Technology Corporation, designed for PC and embedded system applications. It integrates multiple peripheral interfaces including LPC, UARTs, and parallel ports within a single chip to reduce component count. The device operates at a nominal supply voltage of 5 V and supports commercial temperature ranges. It features a QFP-128 package with a pin pitch of 0.5 mm, providing extensive connectivity for legacy and modern system management functions.

Specialized Feature Summary

• Integrates Low Pin Count (LPC) interface for communication with the host processor.
• Includes multiple Universal Asynchronous Receiver/Transmitters (UARTs) for serial communication.
• Provides hardware monitoring capabilities with fan control and thermal sensing inputs.
• Supports keyboard and mouse controller functions for legacy input devices.

Specialized Applications

• Personal Computer (PC) motherboard designs
• Industrial control systems requiring robust I/O integration
• Embedded computing platforms needing legacy port support

Specialized Procurement Notes

Verify the specific suffix FA5B35 E against official Nuvoton documentation to confirm binning or packaging variations. Ensure compliance with current RoHS directives as manufacturing standards may evolve. Cross-reference the part number with authorized distributors to confirm availability status and lead times prior to procurement planning.

Specialized Selection Notes

Select this component when a single-chip solution for LPC-based system management is required. It is suitable for designs needing integrated UARTs, parallel ports, and hardware monitoring without external controllers. Consider package constraints and thermal requirements during PCB layout. Verify compatibility with existing BIOS/UEFI implementations for proper initialization.

Specialized Part Context

The W83667 series belongs to Nuvoton's Super I/O family, widely used in x86-based systems. These chips consolidate various low-speed I/O functions, replacing discrete logic components. The HG variant typically denotes a high-pin-count QFP package, offering expanded I/O options compared to lower-density counterparts in the same product line.

Specialized Replacement Considerations

Check Nuvoton's official obsolescence notices for potential end-of-life status. If replaced, ensure the substitute maintains LPC compatibility and pin-out correspondence. Validate that alternative parts support the same firmware configuration tools and hardware monitoring protocols used in the original design.
