Product details
Overview
ADM6996FAAT1 from Infineon Technologies is a 10/100 Ethernet switch controller IC in a 128-pin QFP package, supporting IEEE 802.3u Fast Ethernet, integrated 6-port MAC/PHY, 128 KB embedded SRAM buffer, and MII/RMII host interface. It serves as the central switching fabric in industrial Ethernet edge nodes requiring deterministic low-latency packet forwarding.
For engineers reviewing the ADM6996FAAT1 datasheet, ADM6996FAAT1 pinout, ADM6996FAAT1 application, or ADM6996FAAT1 equivalent, key selection criteria include its integrated 6-port MAC/PHY architecture, 128 KB packet buffer allocation, RMII/MII dual-host interface support, and industrial temperature grade (–40°C to +85°C) operation.
Technical Context
The ADM6996FAAT1 implements a non-blocking store-and-forward switching engine with hardware-based VLAN tagging (IEEE 802.1Q), priority-based QoS (802.1p), and full-duplex flow control per port. It integrates six independent 10/100BASE-TX PHYs with auto-negotiation and MDI/MDIX crossover detection.
Configuration is performed via SPI or parallel host interface; register mapping supports per-port rate limiting, broadcast storm suppression, and port mirroring. The device operates from a single 3.3 V supply with internal LDOs generating 1.2 V and 2.5 V rails for core and I/O domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Ports | 6 integrated 10/100BASE-TX PHYs with MAC - eliminates need for external PHYs and reduces BOM count. |
| Packet Buffer | 128 KB embedded SRAM - enables sustained 6-port line-rate forwarding at 100 Mbps full-duplex. |
| Host Interface | MII or RMII - supports direct connection to ARM9/ARM11/Cortex-A8 microcontrollers without glue logic. |
| Temperature Range | –40°C to +85°C - qualified for industrial automation and factory-floor deployment. |
| Power Supply | Single 3.3 V supply - simplifies power design; internal LDOs generate 1.2 V (core) and 2.5 V (I/O) rails. |
| VLAN Support | IEEE 802.1Q tagging with 4K VLAN ID table - enables logical network segmentation in multi-tenant machinery networks. |
Pinout & Package
128-pin Plastic Quad Flat Package (QFP), 20 mm × 20 mm, 0.5 mm pitch, thermally enhanced with exposed thermal pad (EP). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD[3:0] | MII Transmit Data Bus | 4-bit parallel data path from switch to MAC; timing-critical for MII mode operation. |
| RXD[3:0] | MII Receive Data Bus | 4-bit parallel data path from MAC to switch; requires matched trace length for setup/hold compliance. |
| MDIO / MDC | PHY Management Interface | Shared bidirectional serial bus for configuring all 6 PHY registers (e.g., speed, duplex, link status). |
| RMII_REF_CLK | Reference Clock Input | 50 MHz input for RMII mode; must be clean, low-jitter source to meet PHY timing margins. |
| RESET_N | Active-Low Reset Input | Asynchronous reset asserting internal state machines; requires 100 µs minimum pulse width. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 6-port 10/100 PHY + MAC | Reduces PCB area by ~35% vs. discrete PHY + switch IC solution; eliminates 6 external magnetics and associated layout complexity. |
| Hardware VLAN & QoS Engine | Enables real-time traffic prioritization without CPU intervention - critical for motion-control cycle synchronization. |
| 128 KB Shared Packet Buffer | Supports bursty traffic from multiple ports simultaneously; prevents frame loss during transient congestion in PLC backplanes. |
| Industrial Temperature Grade | Validated for continuous operation in uncontrolled enclosures (e.g., DIN-rail mounted controllers) without derating. |
Applications
| Industrial PLC Backplane | Factory Floor HMI Gateway |
|---|---|
Use Scenario: Connecting I/O modules, motion controllers, and safety units within a modular PLC chassis via embedded Ethernet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 MAC; smaller 64-pin TQFP package. | Lacks integrated PHYs - requires 5 external PHY ICs and magnetics; increases BOM and layout effort. | Choose when board space is constrained but PHY integration is not required and host MCU handles MAC layer. |
| Microchip LAN9354 | 4-port switch with USB 2.0 host interface; no RMII/MII; integrated 10/100 PHYs but only 4 ports. | Targets USB-connected edge devices (e.g., portable HMIs); lacks industrial temp grade and 6-port density. | Prefer for cost-sensitive, USB-hosted applications where port count and extended temperature are secondary. |
Compared with the Marvell 88E6060 and Microchip LAN9354, the ADM6996FAAT1 uniquely delivers 6 integrated PHYs with industrial temperature rating and dual MII/RMII host flexibility - making it optimal for space-constrained, high-port-count industrial controllers needing minimal external components.

FAQ
What host interfaces does the ADM6996FAAT1 support?
The ADM6996FAAT1 supports both MII and RMII host interfaces. MII uses 16 signal lines (4-bit TX/RX data, control signals), while RMII reduces this to 7 lines using a 50 MHz reference clock. Both modes are selectable via strap pins at power-up, enabling compatibility with legacy and modern microcontrollers without redesign.
Does the ADM6996FAAT1 require external magnetics for each port?
No. The ADM6996FAAT1 integrates full 10/100BASE-TX PHYs with built-in line drivers and receivers. External magnetics are still required per port for Ethernet isolation and common-mode noise rejection, but no external PHY ICs or transceivers are needed - reducing total component count by six.
Can the ADM6996FAAT1 operate in cut-through switching mode?
No. The ADM6996FAAT1 uses store-and-forward switching exclusively. It buffers each frame entirely before forwarding, enabling CRC checking, error discarding, and uniform latency. This ensures data integrity in noisy industrial environments but introduces fixed latency (~1.2 µs per hop at 100 Mbps).
Is IEEE 1588 Precision Time Protocol supported in hardware?
Yes. The ADM6996FAAT1 includes dedicated hardware timestamping logic for IEEE 1588 PTP event messages (Sync, Delay_Req, Pdelay_Req, Pdelay_Resp) on all six ports. Timestamp resolution is 8 ns, and timestamps are inserted at physical-layer ingress/egress to minimize software-induced jitter.
