FDC37C672-MT

Specialized Overview

The FDC37C672-MT is an Enhanced Super I/O Controller manufactured by Microchip Technology, housed in a 100-pin TQFP package. It operates on a 5V supply with a voltage range of 4.5V to 5.5V. The device supports ISA bus compatibility and features a maximum functional clock frequency of 14.32 MHz. It includes two serial ports and complies with PC98/99 and ACPI 1.0 standards. Key internal resources include shadowed write-only registers for ACPI compliance and intelligent auto power management capabilities.

Specialized Feature Summary

• Supports PC98/99 and ACPI 1.0 compliance standards
• Features intelligent auto power management
• Includes shadowed write-only registers for ACPI compliance
• ISA Plug-and-Play compatible register set

Specialized Applications

• Super I/O controller implementations in personal computers
• Systems requiring PC98/99 standard compliance
• ACPI 1.0 compliant hardware designs

Specialized Procurement Notes

Verify the manufacturer designation carefully, as the FDC37C672 was originally developed by SMSC before its acquisition by Microchip Technology. Confirm that the specific suffix '-MT' corresponds to the required 100-TQFP packaging and commercial temperature grade. Ensure the component meets RoHS3 specifications if environmental compliance is a project requirement.

Specialized Selection Notes

Select this component when an ISA-compatible Super I/O solution with integrated Fast IR support is required. It is suitable for legacy system maintenance or designs adhering to PC98/99 standards. Consider the 100-pin TQFP footprint during PCB layout planning. Verify that the 5V operation aligns with the target system's power architecture.

Specialized Part Context

This component belongs to the FDC37C6xx series of Enhanced Super I/O Controllers. It serves as a multifunction peripheral integrating serial communication and power management functions. The device bridges ISA bus interfaces with low-speed peripheral connections, providing a consolidated solution for system control tasks in desktop and industrial computing environments.

Specialized Replacement Considerations

The FDC37C669-MT is a documented substitute within the same product family. Both devices share similar pinouts and functional characteristics, facilitating potential interchangeability in existing designs without significant schematic modifications.
