Product details
Overview
ADM6996LC-AC-R-1 from Infineon Technologies is a six-port 10/100 Mbps L2 Ethernet switch controller with integrated MDIX TX/FX transceivers, hardware/software IGMP snooping, 16 VLAN support, Layer 4 QoS, and 802.1x security-designed for ADSL routers and home gateways requiring deterministic traffic prioritization and multicast control.
For engineers reviewing the ADM6996LC-AC-R-1 datasheet, ADM6996LC-AC-R-1 pinout, ADM6996LC-AC-R-1 application, or ADM6996LC-AC-R-1 equivalent, key selection criteria include 128-pin LQFP package compatibility, RMII/MII interface support, 1784-byte maximum packet length, and hardware-accelerated IGMP/STP functions in cost-sensitive broadband CPE designs.
Technical Context
The ADM6996LC-AC-R-1 implements a full L2 switching engine with 2K MAC address table capacity, 4-layer hashing, and hardware-based learning handler. It supports both MII and RMII host interfaces, enabling direct connection to ARM or MIPS CPUs without external PHY bridging.
Its ingress/egress bandwidth control scales from 64 Kbps to 100 Mbps per port in 64 Kbps increments, and it enforces multicast broadcast storm protection via configurable rate limiting and packet filtering on TCP/UDP destination port, IP protocol ID, and Ethernet type fields.

Key Features
| Feature | Design Value |
|---|---|
| Hardware IGMP Snooping | Reduces multicast flooding by dynamically updating forwarding table based on IGMP join/leave messages-critical for VOD scalability |
| L4 Quality of Service | Classifies and prioritizes traffic using TCP/UDP port numbers, IP protocol ID, and DSCP fields-enables real-time VoIP and gaming latency control |
| Port Mirroring | Replicates ingress/egress frames from any port to a designated monitoring port-supports inline network analysis without TAP hardware |
| Advanced Filtering | Applies per-port rules on Ethernet type, IP protocol, and TCP/UDP destination port-blocks unauthorized protocols at wire speed |
| Spanning Tree Protocol | IEEE 802.1D STP implementation prevents Layer 2 loops in meshed home networks with redundant uplinks |
Applications
| ADSL Router | Home Gateway |

Equivalent & Alternatives
The following parts are listed as comparable options for similar L2 Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM6996M-AC-R-1 | Includes IPv4/v6 DiffServ priority, TAG PRI replacement, and enhanced IGMP snooping not present in LC variant | Required for IPv6-ready CPE deployments needing DSCP-to-802.1p mapping and VLAN priority override | Select when future-proofing for IPv6 transition or carrier-grade QoS policy enforcement |
| RTL8306SD-GR | 6-port 10/100 switch with 16 KB packet buffer but no integrated PHY; requires external transceivers | Used in cost-optimized designs where PHY selection is decoupled for flexibility or legacy compatibility | Select when board space allows discrete PHY placement or when specific PHY features (e.g., EEE, fiber) are needed |
Compared with ADM6996M-AC-R-1, the LC variant trades IPv6 QoS extensions for lower BOM cost and smaller footprint; versus RTL8306SD-GR, it delivers higher integration (PHY+switch+memory) at the expense of PHY customization freedom-making LC optimal for volume DSL/Cable CPE where time-to-market and thermal constraints dominate.

FAQ
Does ADM6996LC-AC-R-1 support Jumbo Frames?
Yes, it supports packets up to 1784 bytes-exceeding standard 1518-byte Ethernet frames. This enables efficient transport of VoIP and IPTV payloads without fragmentation, provided the connected PHYs and upstream devices also support extended frame sizes.
What is the function of the GPSI interface on ADM6996LC-AC-R-1?
The GPSI (General Purpose Serial Interface) provides a 4-wire SPI-compatible bus for connecting to external devices such as SLICs, PA drivers, or custom ASICs. It operates at up to 25 MHz and supports full-duplex synchronous data transfer independent of the main MII/RMII paths.
Can ADM6996LC-AC-R-1 operate without an external EEPROM?
No-it requires an external 2-wire serial EEPROM to store initialization parameters including VLAN configuration, port settings, and security policies. The device halts boot until valid EEPROM data is loaded via SCL/SDA pins during power-up reset.
Is RMII mode mandatory when using ADM6996LC-AC-R-1 with an ARM9 CPU?
No-RMII is optional. The device supports both MII (16-signal interface) and RMII (7-signal interface). RMII reduces pin count and PCB layers but requires the CPU to provide a 50 MHz reference clock; MII offers greater timing margin and broader CPU compatibility.
