PC87323VUL

Overview

The PC87323VUL is a hardware monitoring and fan control controller manufactured by National Semiconductor. It is housed in a 160-lead BFQFP package with dimensions of 28x28 mm, designed for surface-mount technology applications. The device operates within the PC87323 series and functions as a specialized integrated circuit for system management tasks. As an input/output controller interface IC, it provides essential monitoring capabilities for computer systems. The component is supplied in bulk packaging and is intended for use in environments requiring precise thermal and voltage regulation.

Feature Summary

• Integrated hardware monitoring and fan control functionality
• 160-lead BFQFP package (28x28 mm) for surface mounting
• Part of the PC87323 series for system management

Applications

• Computer system hardware monitoring
• Fan speed control in computing platforms
• Thermal management in embedded systems

Procurement Notes

Verify the manufacturer designation as National Semiconductor, noting that this entity has undergone corporate restructuring. Confirm the specific package type is 160-BFQFP and the supplier device package is 160-QFP (28x28). Ensure the product grade and qualification status are explicitly stated if required for your application, as these fields are currently unlisted in the provided data.

Selection Notes

Select this component when a dedicated hardware monitor with fan control is required for a system utilizing a 160-pin QFP footprint. The 28x28 mm case size must be accommodated on the PCB layout. Consider the availability of the PC87323 series documentation for integration. Verify compatibility with the target system's voltage levels and interface requirements before procurement.

Part Context

This component belongs to the PC87323 series of Super I/O controllers. These devices typically integrate multiple interfaces and monitoring functions into a single chip. The PC87323VUL specifically denotes the variant in the 160-QFP package. It serves as a bridge between the system bus and peripheral monitoring sensors, providing data for system health management.

Replacement Considerations

Check for direct pin-to-pin replacements within the PC87323 family or updated equivalents from the current manufacturer lineage. Verify that any substitute maintains the 160-lead BFQFP form factor and identical electrical characteristics for hardware monitoring and fan control.
