DP83810BVUL

Controllers Overview

The DP83810BVUL is a single-chip Ethernet transceiver manufactured by National Semiconductor, now part of Texas Instruments. It integrates a Media Access Controller (MAC) and Physical Layer (PHY) for 10/100 Mb/s networks. The device supports full-duplex operation with IEEE 802.3x flow control and half-duplex backpressure. It features an integrated PCI interface compliant with PCI Local Bus Specification Revision 2.2. Power consumption is optimized for low-voltage applications, typically operating at 3.3V. The component utilizes a 64-pin TQFP package to facilitate compact board designs while maintaining robust signal integrity for industrial and commercial environments.

Controllers Feature Summary

• Integrates MAC and PHY functions into a single silicon die
• Supports standard PCI bus interface for host connectivity
• Enables automatic MDI/MDI-X crossover detection
• Provides comprehensive diagnostic capabilities via management interface

Controllers Applications

• Industrial automation controllers requiring reliable Ethernet connectivity
• Embedded systems with limited board space constraints
• Network infrastructure equipment such as switches and routers
• Point-of-sale terminals and retail computing devices

Controllers Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Ensure the specific suffix matches the required package type and temperature range. Confirm RoHS compliance status through official documentation, as legacy stock may differ from current production runs. Cross-reference the datasheet revision to ensure compatibility with your system design requirements before finalizing procurement orders.

Controllers Selection Notes

Select this component when a combined MAC and PHY solution is necessary to reduce bill of materials count. It is suitable for designs utilizing a PCI host interface without needing separate controller chips. Consider power supply constraints, as the device operates on a single 3.3V rail. Evaluate thermal performance within the TQFP package if high ambient temperatures are expected in the target application environment.

Controllers Part Context

This part belongs to the DP8381x family of Ethernet transceivers designed for cost-effective network integration. The series provides a complete solution for 10/100BASE-TX applications. National Semiconductor developed this line to simplify network interface card designs. Texas Instruments continues to support the lineage following the acquisition, maintaining technical documentation for existing designs.

Controllers Replacement Considerations

The DP83810DVNG is a pin-compatible alternative within the same product family. Verify electrical specifications and package dimensions before substitution. Check for any differences in manufacturing origin or quality certifications between the original National Semiconductor parts and current Texas Instruments inventory.
