Product details
Overview
ADM6996LCX-AC-T-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 - deployed in ADSL routers and home gateways requiring full-duplex switching and multicast traffic management.
For engineers reviewing the ADM6996LCX-AC-T-1 datasheet, ADM6996LCX-AC-T-1 pinout, ADM6996LCX-AC-T-1 application, or ADM6996LCX-AC-T-1 equivalent, key selection criteria include IEEE 802.1p/q compliance, 128-pin LQFP package compatibility, RMII/MII interface support, and 1784-byte maximum packet length handling for broadband edge devices.
Technical Context
The ADM6996LCX-AC-T-1 implements a fully integrated L2 switching fabric with five 10/100 Mbps PHY ports plus one MAC-only port (Port 5), supporting both MII and RMII host interfaces. Its learning handler maintains a 2K-entry MAC address table using 4-layer hashing and supports 12-bit VLAN ID learning.
It delivers deterministic Layer 4 QoS via TCP/UDP destination port and IP protocol ID filtering, enforces ingress/egress bandwidth control scalable from 64 Kbps to 100 Mbps in 64 Kbps steps, and provides hardware-accelerated IGMP snooping and multicast broadcast storm protection.
Key Specifications

Pinout & Package
Package: 128-pin LQFP (20 mm × 20 mm, 0.4 mm pitch), RoHS-compliant, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MDIO / MDC | Management Data I/O / Clock | IEEE 802.3 clause 22 serial interface for PHY register configuration and status readback |
| RMII_CLK / RXD[1:0] / TXD[1:0] | RMII Interface Signals | Enables 2-pin clock + 4-pin data RMII connection to host CPU, reducing pin count vs. full MII |
| LED[0:5] | Link/Activity Status Outputs | Dedicated open-drain outputs per port for direct LED drive without external drivers |
| XTAL_IN / XTAL_OUT | Crystal Oscillator Interface | Supports 25 MHz crystal for PHY timing; internal PLL generates all required clocks |
| EEPROM_SCL / SDA | I²C Configuration Interface | Loads startup configuration (VLAN, QoS, security settings) from external EEPROM at power-on |
Key Features
| Feature | Design Value |
|---|---|
| Hardware IGMP Snooping | Reduces multicast flooding by dynamically updating forwarding decisions based on IGMP join/leave messages - essential for VOD delivery |
| L4 QoS Classification | Filters and prioritizes traffic using TCP/UDP destination port, IP protocol ID, and Ethernet type - enables real-time VoIP and gaming latency control |
| Bandwidth Control Granularity | 64 Kbps step resolution across 64 Kbps–100 Mbps range - allows precise SLA enforcement per subscriber port in CPE |
| Port Mirroring | Configurable copy of ingress/egress frames from any port to designated monitor port - supports network diagnostics without inline taps |
| Multicast Storm Protection | Automatically limits unknown multicast/broadcast rate per port - prevents switch saturation during topology changes or misconfigurations |

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 |
|---|---|---|---|
| ADM6996FCX-AC-T-1 | Same core switch engine but uses 128-pin LQFP with different pinout for Fast Ethernet PHYs; lacks RMII support | Targeted at legacy designs using MII-only host interfaces and discrete PHYs | Select when migrating from ADM6995L-series and retaining existing MII layout |
| RTL8306SD-GR | 6-port 10/100 switch with 16K MAC table, no integrated PHYs, requires external magnetics and PHYs | Suitable for cost-sensitive designs where PHY selection is flexible and board space allows discrete components | Choose when needing larger MAC table depth and external PHY customization, accepting higher BOM and layout complexity |
Compared with ADM6996FCX-AC-T-1, the LC variant adds RMII support and tighter power optimization; versus RTL8306SD-GR, it trades MAC table size for integrated PHYs and lower system-level power (1.0 W vs. ~1.8 W).

FAQ
Does ADM6996LCX-AC-T-1 support IPv6 QoS features?
No. IPv6 DiffServ priority and related IPv6 QoS functions are exclusive to the ADM6996M/I packages. The LC variant implements only IPv4-based L4 classification using TCP/UDP port and IP protocol ID fields, with no IPv6 header parsing capability.
What is the function of the GPSI interface on ADM6996LCX-AC-T-1?
The GPSI (General Purpose Serial Interface) is a 4-wire SPI-compatible bus used for firmware updates, debug access, and secondary configuration loading. It operates independently of MII/RMII and supports up to 10 MHz clock rate for fast programming of internal registers and tables.
Can ADM6996LCX-AC-T-1 operate without an external EEPROM?
Yes. Default configuration is stored in mask ROM; EEPROM is optional for field-upgradable settings like VLAN maps, QoS rules, and port mirroring targets. If absent, the device boots with factory-default parameters and supports runtime reconfiguration via MDC/MDIO or CPU interface.
Is the 128-pin LQFP footprint compatible with other Samurai variants?
Pin compatibility exists only within the LC/FC subfamily. ADM6996LCX-AC-T-1 shares identical pinout with ADM6996FCX-AC-T-1 but differs from M/I packages due to RMII signal placement and removed legacy test pins - verify layout against Infineon's AN245 package migration guide before redesign.
