ADM6996LC-AC-R-1

Overview

The ADM6996LC-AC-R-1 is an L2 Ethernet switch controller from the Samurai family, integrating five 10/100 Mbps MDIX TX/FX transceivers and a MAC interface within a 128-pin LQFP package. It supports full/half duplex operation at 10/100 Mb/s with Layer 4 QoS, 802.1p/QoS, and 802.1q VLAN capabilities. The device features hardware and software IGMP, port mirroring, spanning tree, and PPPoE identification. It includes scalable ingress/egress bandwidth control ranging from 64K to 100M, 16 VLANs with 12-bit ID learning, and MDC/MDIO support.

Feature Summary

• Integrates five 10/100 Mbps PHY transceivers with a central MAC controller for compact design
• Provides Layer 4 Quality of Service (QoS) and advanced security functions including 802.1x authentication
• Supports comprehensive network management via hardware/software IGMP, port mirroring, and spanning tree protocols
• Enables flexible traffic filtering through VLAN tagging, PPPoE identification, and scalable bandwidth control

Applications

• ADSL Routers
• Wireless/Wired Routers
• Home Gateways
• Cable Modems
• Web DVDs

Procurement Notes

Verify component authenticity by cross-referencing the ordering number with Infineon official documentation. Confirm that the specific suffix matches the required feature set, as legacy variants may differ in supported protocols or pin compatibility. Ensure compliance with RoHS3 standards and check moisture sensitivity levels prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this model when a cost-effective, integrated solution for low-port switches is required. It offers smooth migration from legacy ADM6996/5L/F series due to pin compatibility. Consider the LC variant specifically if advanced features like IPv6 DiffServ or TCP/UDP destination port priorities are not needed, as these are reserved for the M/I packages. Verify RMII MAC interface requirements against system constraints.

Part Context

This component belongs to the Samurai family of high-performance, low-cost Ethernet switch controllers. The family integrates controller, PHY, and memory functions into a single chip. The LC designation indicates a specific tier within the product line, offering core switching capabilities while omitting certain advanced Layer 4 features found in the M and I variants, ensuring a balance between performance and manufacturing economy.

Replacement Considerations

The ADM6996LC is pin-compatible with the legacy ADM6996L/F series, allowing for direct board upgrades. For enhanced feature sets, consider the ADM6996M or ADM6996I models, which add IPv4/v6 DiffServ and advanced filtering. The ADM6995LCL2 serves as a five-port alternative within the same ecosystem.
