DP83932CVF-33

Controllers Overview

The DP83932CVF-33 is a system-oriented network interface controller manufactured by National Semiconductor. It integrates an Ethernet MAC and PHY to support IEEE 802.3 standards for local area networks using CSMA/CD access methods. The device operates at a clock frequency of 33 MHz, as indicated by the suffix. It is housed in a VF package, which corresponds to a specific surface-mount footprint. This component functions as a bridge between host processors and physical Ethernet media, handling data link layer protocols and physical layer signaling within a single integrated circuit.

Controllers Feature Summary

• Integrates Media Access Control (MAC) and Physical Layer (PHY) functionalities
• Supports Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocols
• Designed for system-oriented network interface applications

Controllers Applications

• Local Area Network (LAN) node implementation
• Ethernet-based embedded systems
• Network interface controllers for consumer or industrial circuits

Controllers Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the exact package dimensions and pinout for the VF suffix against current datasheets. Ensure compatibility with the required 33 MHz operating speed and voltage levels specified in the official documentation before integration.

Controllers Selection Notes

Select this component when a combined MAC and PHY solution is required for IEEE 802.3 compliance. The 33 MHz variant suits systems needing that specific clock rate. Compare pinouts and electrical characteristics with other variants in the DP83932 family to ensure mechanical and electrical fit for the target design.

Controllers Part Context

The DP83932 series represents National Semiconductor's approach to simplifying Ethernet connectivity by combining MAC and PHY layers. The CVF-33 designation specifies the commercial temperature range, VF package type, and 33 MHz operational frequency. This integration reduces board space and component count compared to discrete solutions.

Controllers Replacement Considerations

Check for equivalents from Texas Instruments following the acquisition of National Semiconductor. Verify if newer revisions of the DP83932 series offer improved performance or updated packaging while maintaining pin compatibility.
