W83627DHG-AC TR

Overview

The W83627DHG-AC TR is an LPC Super I/O controller interface IC manufactured by Nuvoton Technology Corporation. It integrates hardware monitoring, smart fan control, and PECI 1.1a support within a QFP-128 package. The device operates at a fixed supply voltage of 2.048 V and supports a wide industrial temperature range from -40°C to +85°C. Key features include SPI interface connectivity, 40 general-purpose I/O lines, six communication ports, and an integrated watchdog timer for system reliability.

Feature Summary

LPC Super I/O architecture with PECI 1.1a and SST support
Smart Fan III+ technology for automated thermal management
Industrial temperature rating (-40°C to +85°C)
Integrated hardware monitoring and watchdog timer

Applications

Industrial embedded systems requiring robust I/O control
Hardware monitoring solutions in server environments
Systems utilizing PECI for processor thermal management

Procurement Notes

This specific part number (W83627DHG-AC TR) is listed as discontinued or obsolete in available distributor records. Verification of current availability requires direct consultation with Nuvoton Technology Corporation or authorized channel partners. Designers should confirm end-of-life status and lead times before finalizing procurement plans.

Selection Notes

Select this component when an LPC Super I/O with PECI support and industrial temperature range is required. Ensure the design accommodates the 2.048 V operating voltage and QFP-128 footprint. Verify that the 40 I/O count and six-port configuration meet the system's peripheral requirements.

Part Context

The W83627 series represents Nuvoton's line of Super I/O controllers designed for legacy and modern LPC bus interfaces. The DHG variant specifically targets applications needing enhanced thermal management via Smart Fan III+ and precise power monitoring capabilities within a compact 128-pin form factor.

Replacement Considerations

As the W83627DHG-AC TR is marked as obsolete, engineers must identify pin-compatible or functionally equivalent replacements from Nuvoton's current portfolio. Cross-referencing datasheets for LPC compatibility, voltage levels, and package dimensions is essential for successful substitution.
