LPC47M182-NR

Specialized Overview

The LPC47M182-NR is a Super I/O controller manufactured by Standard Microsystems Corporation (SMSC). It integrates hardware monitoring, fan control, and peripheral interfaces into a single CMOS package. The device supports the Low Pin Count (LPC) interface and complies with ACPI standards for power management. It includes programmable wake-up events and system management interrupts. The component features general-purpose input/output pins and supports legacy interfaces such as ISA plug-and-play. It is designed for notebook and desktop computer systems requiring integrated I/O and environmental monitoring capabilities.

Specialized Feature Summary

• Integrates hardware monitoring block with fan speed control outputs and tachometer inputs
• Supports programmable wake-up event interface and system management interrupt
• Includes MPU-401 MIDI support and dual game port interface
• Features intelligent auto power management with multiple powerdown modes

Specialized Applications

• Notebook computer controllers
• Desktop motherboard I/O integration
• Hardware monitoring and thermal management systems
• Legacy peripheral interface expansion

Specialized Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm RoHS compliance status through official SMSC documentation or authorized distributor datasheets. Ensure compatibility with existing LPC bus implementations on the target motherboard design before procurement.

Specialized Selection Notes

Select this component when integrating Super I/O functions with hardware monitoring in space-constrained designs. Compare pinout and register compatibility with existing LPC47 series variants if replacing older components. Verify voltage tolerance levels for SIO blocks against system power rails.

Specialized Part Context

The LPC47M182-NR belongs to the LPC47M family of Super I/O controllers from SMSC. This series was widely used in late 1990s and early 2000s PC architectures. It succeeded earlier parallel I/O controllers by offering reduced pin counts via the LPC interface while maintaining software compatibility with legacy ISA devices.

Specialized Replacement Considerations

Check for direct pin-to-pin replacements within the LPC47M series such as the LPC47M152 or LPC47M172. Verify register-level compatibility if substituting with other SMSC Super I/O parts. No cross-manufacturer substitutes are officially documented.
