DP83815DVNG

Controllers Overview

The DP83815DVNG is a single-channel 10/100 Mb/s integrated PCI Ethernet Media Access Controller and Physical Layer device, marketed as MacPhyter. It operates within a voltage range of 3.0 V to 3.6 V, with a rated supply of 3.3 V. The component supports a maximum data transmission rate of 100 Mbps and features a 32-bit external data bus width. It utilizes a 144-terminal LQFP package with a 0.50 mm pitch, designed for surface mount applications. The device functions in commercial temperature environments ranging from 0°C to 70°C.

Controllers Feature Summary

• Integrates both MAC and PHY functions into a single chip solution
• Provides direct interface capability with PCI buses
• Supports standard 10BASE-T and 100BASE-TX Ethernet media

Controllers Applications

• Embedded systems requiring integrated Ethernet connectivity
• Industrial control networks utilizing PCI interfaces
• Consumer electronics with space-constrained PCB layouts

Controllers Procurement Notes

Verify the specific suffix 'DVNG' against the manufacturer's current product status documentation. Confirm that the lead-free designation aligns with project requirements. Ensure compatibility with existing PCI bus architectures before procurement. Cross-reference the datasheet revision date to confirm technical accuracy.

Controllers Selection Notes

Select this component when a combined MAC and PHY solution is required for PCI-based designs. Verify that the 3.3V logic levels match the host system. Ensure the LQFP-144 footprint fits the mechanical constraints. Check if the 100 Mbps speed meets the application bandwidth needs.

Controllers Part Context

This part belongs to the National Semiconductor DP8381x series of MacPhyter devices. These components were designed to simplify Ethernet integration by combining media access control and physical layer signaling. The series targets applications needing compact, low-pin-count Ethernet solutions for PCI-connected hosts.

Controllers Replacement Considerations

The DP83815DVNG/NOPB is a documented equivalent variant. Verify pinout and electrical specifications match exactly. Consult official substitution guides for any functional differences between leaded and lead-free versions.
