Product details
Overview
ADM6996LC-AC-T-1 from Infineon Technologies is a single-chip 6-port 10/100 Mbit/s Ethernet switch controller integrating full PHY, MAC, and switching fabric. It supports IEEE 802.3u auto-negotiation, MDI/MDIX crossover detection, VLAN tagging (802.1Q), and hardware-based broadcast/multicast storm filtering. The device operates with 3.3 V core and I/O supply, features integrated clock synthesizer, and targets embedded networking in SOHO routers and industrial gateways.
For engineers reviewing the ADM6996LC-AC-T-1 datasheet, ADM6996LC-AC-T-1 pinout, ADM6996LC-AC-T-1 application, or ADM6996LC-AC-T-1 equivalent, key selection criteria include integrated PHY count, MII/RMII interface flexibility, hardware VLAN support, bandwidth control granularity, and green package compliance for RoHS-constrained designs.
Technical Context
The ADM6996LC-AC-T-1 implements a non-blocking store-and-forward switching architecture with 16 KB internal packet buffer memory and fully autonomous address learning (up to 1024 entries). Its six integrated 10/100BASE-TX PHYs share a common analog front-end but operate independently with per-port auto-negotiation and link status monitoring.
It supports both 32-bit and 16-bit serial EEPROM configuration modes, enabling flexible boot-time initialization. The switch engine enforces priority-based queuing via four configurable traffic classes and provides hardware-accelerated ingress/egress bandwidth control with 1 Mbps resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Port Count | 6 × 10/100 Mbit/s Ethernet ports with integrated PHYs - eliminates need for external transceivers. |
| Switching Capacity | 1.2 Gbit/s non-blocking throughput - supports full-duplex line-rate forwarding on all ports simultaneously. |
| MAC Address Table | 1024-entry hardware address table with automatic aging (configurable 15–4095 s) - reduces software management overhead. |
| VLAN Support | IEEE 802.1Q tag insertion/stripping and port-based VLAN - enables logical network segmentation without external switches. |
| Bandwidth Control | Scalable per-port ingress/egress rate limiting (1–100 Mbps in 1 Mbps steps) - prevents congestion in asymmetric traffic scenarios. |
| Interface Options | MII, RMII, and CPU bus modes - allows direct connection to ARM7/ARM9 or MIPS microcontrollers without glue logic. |
| Power Supply | Single 3.3 V supply for core and I/O - simplifies power design and reduces BOM cost. |
Pinout & Package
ADM6996LC-AC-T-1 is housed in a 128-pin LQFP (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are defined across five functional groups: PHY analog I/O (RJ-45 differential pairs), digital interfaces (MII/RMII/CPU bus), configuration (EEPROM, strapping), power/ground, and system control (reset, LED drivers).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXOP0–TXON0 | Port 0 100BASE-TX Transmit Differential Output | Drives twisted-pair cable directly; requires 50 Ω series termination and 1:1 isolation transformer. |
| RXIP0–RXIN0 | Port 0 100BASE-TX Receive Differential Input | Accepts transformer-coupled signal; internal adaptive equalizer compensates for cable loss up to 100 m. |
| MDC/MDIO | IEEE 802.3 Clause 22 Management Interface | Allows host MCU to read/write PHY registers and monitor link status per port without interrupt overhead. |
| LED0–LED5 | Per-Port Link/Activity Status Outputs | Open-drain outputs drive dual-color LEDs directly; configurable for link-only, activity-only, or combined mode. |
| RESET_N | Active-Low Asynchronous Reset Input | Pulls entire switch into known state; must be held low ≥100 ns after power stabilization before release. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6× PHY + MAC + Switch Fabric | Reduces bill-of-materials by eliminating 6 discrete PHY ICs and external switch controller logic. |
| Hardware Broadcast/Multicast Storm Filtering | Blocks excessive broadcast/multicast frames at silicon level - prevents CPU overload in noisy LAN environments. |
| Auto MDI/MDIX on All Ports | Eliminates need for crossover cables or manual port configuration - improves field deployment robustness. |
| Configurable Priority Queuing (4 Levels) | Enables QoS for VoIP or real-time control traffic without external traffic shapers or software scheduling. |
| Green Package (Pb-Free, Halogen-Free) | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020D reflow profile - supports eco-compliant manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 6-port Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88E6060-B0-NNC1C000 | 5-port switch with external PHY requirement; no integrated 100BASE-TX PHYs; uses 1.8 V core. | Lacks full PHY integration - requires 5 additional PHY ICs and level-shifting circuitry. | Select when board space permits discrete PHY layout and lower core voltage is required for power optimization. |
| Microchip KSZ8863MLL | 3-port switch with MII only; no RMII or CPU bus interface; supports only 10/100 half-duplex on two ports. | Insufficient port count and duplex capability for 6-port line-rate applications. | Consider only for cost-sensitive 3-port edge node designs where full 6-port switching is not required. |

FAQ
Does ADM6996LC-AC-T-1 support Gigabit Ethernet?
No. The ADM6996LC-AC-T-1 supports only 10/100 Mbit/s per port. It lacks 1000BASE-T PHY circuitry, GMII/RGMII interfaces, and the 2.5 Gbit/s switching fabric required for Gigabit operation. Its architecture is optimized for 100 Mbps line-rate forwarding across six ports with minimal power and footprint.
Can ADM6996LC-AC-T-1 operate without an external EEPROM?
Yes. The device supports strap-pin configuration for basic operation (e.g., default PHY settings, fixed port speed/duplex), but full feature enablement - including VLAN setup, priority mapping, and bandwidth control - requires serial EEPROM initialization. Without EEPROM, advanced switching functions remain disabled.
What is the maximum operating junction temperature for ADM6996LC-AC-T-1?
The maximum junction temperature is +85 °C, as specified in the Rev. 1.31 datasheet Section 6.1 (Absolute Maximum Ratings). Thermal design must ensure the exposed pad is soldered to ≥4 cm² of inner-layer copper pour with ≥6 thermal vias to maintain safe operation under full 6-port line-rate load.
Is RMII interface supported on all six ports simultaneously?
No. RMII is a shared interface supporting only one external MAC controller. All six ports remain internally switched; RMII provides a single 2x50 MHz path to the host processor. Port 5 can alternatively be configured as MII for connection to a second MAC, but RMII and MII cannot operate concurrently.
