W83627UHG

Specialized Overview

The W83627UHG is an LPC Super I/O controller manufactured by Nuvoton Technology Corporation. It integrates a Low Pin Count (LPC) interface with comprehensive input/output capabilities, including six full-function Universal Asynchronous Receiver/Transmitters (UARTs). The device supports legacy interfaces such as floppy disk controllers, multi-mode parallel ports, and keyboard/controller interfaces. It features hardware monitoring for system stability and power management functions compliant with ACPI standards. The component is available in a 128-pin QFP package.

Specialized Feature Summary

• Integrates multiple communication interfaces including six UARTs and legacy FDC support
• Provides hardware monitoring for voltage, temperature, and fan speed tracking
• Supports advanced power management states and wake-up events via LPC bus

Specialized Applications

• Desktop and server motherboard system control
• Industrial PC embedded control systems
• Legacy peripheral integration in modern computing platforms

Specialized Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm package type and revision level against design requirements. Ensure sourcing from authorized distributors to guarantee authenticity. Check for end-of-life notifications prior to finalizing procurement plans.

Specialized Selection Notes

Select this component when LPC interface compatibility is required alongside extensive serial port expansion. Evaluate pin count and thermal dissipation requirements for the 128-pin QFP package. Consider alternative models if higher performance or different interface configurations are needed. Verify software driver support for the specific operating environment.

Specialized Part Context

This part belongs to the W83627 series of Super I/O controllers, which are widely used in PC architecture for managing legacy I/O functions. The UHG suffix typically denotes specific packaging or temperature grade variations within the product line. It serves as a bridge between the LPC bus and traditional peripheral devices.

Specialized Replacement Considerations

Check for direct pin-compatible replacements within the same Nuvoton family. Verify functional equivalence regarding UART counts and interface support. Review datasheet revisions for any changes in electrical characteristics or pin assignments before substitution.
