LPC47M102S-MC

Specialized Overview

The LPC47M102S-MC is a Super I/O controller manufactured by SMSC, designed for PC and notebook applications. It integrates standard I/O functions including serial ports, parallel ports, floppy disk controller, keyboard/mouse controller, and hardware monitoring capabilities within a single chip. The device supports the Low Pin Count (LPC) interface for communication with the host processor, offering a cost-effective solution for system management and peripheral control in computing platforms.

Specialized Feature Summary

• Integrates multiple legacy I/O interfaces such as UARTs, parallel port, and floppy disk controller into a single package to reduce board space and component count.
• Features hardware monitoring capabilities allowing real-time tracking of system voltages, temperatures, and fan speeds for enhanced system reliability.
• Supports ACPI power management standards to enable efficient system sleep states and intelligent auto-power management features.

Specialized Applications

• Personal computer motherboard design
• Notebook computer system integration
• Industrial control systems requiring legacy I/O support

Specialized Procurement Notes

Verify the specific suffix 'MC' against official SMSC documentation to confirm pinout compatibility and temperature grade. Ensure the source document explicitly lists this part number to avoid confusion with similar LPC47 series variants that may have different electrical characteristics or package options.

Specialized Selection Notes

Select this component when a single-chip solution is required to replace multiple discrete I/O controllers. It is suitable for designs needing integrated hardware monitoring and standard PC98/PC99 compliance without requiring additional external logic chips for basic peripheral control.

Specialized Part Context

This part belongs to the SMSC LPC47M series of Super I/O controllers. These devices are widely used in x86-based systems to manage low-speed peripherals. The LPC interface allows for reduced pin counts compared to older ISA bus interfaces while maintaining backward compatibility with legacy software drivers.

Specialized Replacement Considerations

Check for direct replacements within the LPC47M family, such as the LPC47M102 or LPC47M152, ensuring functional equivalence in I/O channels and monitoring blocks. Verify package compatibility if substituting with other manufacturers' equivalents.
