W83627DHG-UB5A01009AE-E VERSION

Specialized Overview

The W83627DHG-UB5A01009AE-E VERSION is a specialized LPC Super I/O interface controller manufactured by Nuvoton Technology Corporation. It integrates hardware monitoring, smart fan control, and power management features within a 128-pin QFP package. The component supports the PECI 1.1a protocol and SST standards. It operates at a fixed voltage of 2.048 V and functions within an extended industrial temperature range from -40°C to +85°C. The device provides 40 general-purpose I/O lines across six ports and utilizes an SPI interface for communication.

Specialized Feature Summary

• Supports Smart Fan III+ technology for automated thermal management
• Integrates PECI 1.1a and SST capabilities for processor communication
• Provides comprehensive hardware monitoring for system stability

Specialized Applications

• Industrial computing systems requiring wide temperature operation
• Embedded platforms utilizing LPC or SPI Super I/O interfaces
• Hardware monitoring solutions in server infrastructure

Specialized Procurement Notes

Verify the exact suffix designation against official Nuvoton documentation before procurement, as variant codes may indicate specific manufacturing revisions or regional compliance differences. Confirm current production status, as this part number has been identified as Not Recommended for New Designs (NRND) in public distributor records. Ensure compatibility with existing board layouts regarding the 128QFP footprint and 2.048V supply requirements.

Specialized Selection Notes

Select this component when an LPC Super I/O controller with extended temperature ratings (-40°C to +85°C) is required. It is suitable for designs needing integrated hardware monitoring and smart fan control without external sensors. Verify that the system architecture supports the 2.048V operating voltage and SPI interface. Consider the NRND status for long-term production viability and evaluate alternative newer generations if available.

Specialized Part Context

This model belongs to the W83627 series of Super I/O controllers from Nuvoton. The series is designed for PC and embedded applications, combining standard I/O functions with advanced power management and hardware monitoring. The DHG suffix typically denotes a specific package and temperature grade variation within the broader product family.

Specialized Replacement Considerations

Public sources identify the W83627DHG-PT as a related variant within the same series. However, verify functional equivalence carefully, as suffixes often denote differences in packaging, temperature range, or internal configuration. No other direct substitute part numbers are confirmed in public documentation.
