Product details
Overview
ADM6999GA2T1 from Infineon Technologies is a 10/100 Ethernet switch controller IC with integrated MAC and PHY, supporting IEEE 802.3u Fast Ethernet, 128-pin FQFP package, and 3.3 V I/O voltage. It enables embedded network edge switching in industrial gateways requiring deterministic latency and low-power operation.
For engineers reviewing the ADM6999GA2T1 datasheet, ADM6999GA2T1 pinout, ADM6999GA2T1 application, or ADM6999GA2T1 equivalent, key selection criteria include MII/RMII interface compatibility, integrated PHY performance, power consumption at 100 Mbps, and industrial temperature range support.
Technical Context
The ADM6999GA2T1 integrates a 3-port 10/100 Ethernet switch fabric with one external MII/RMII interface and two internal PHYs. It implements store-and-forward packet handling, supports IEEE 802.1Q VLAN tagging, and includes hardware-based priority queuing with four traffic classes.
It features an embedded ARM7TDMI core for management plane operations, supports SNMPv1/v2c via embedded agent, and delivers <15 μs end-to-end latency at 100 Mbps full-duplex. The device operates across –40°C to +85°C and meets EN 55032 Class B emission limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Ports | 3-port integrated switch: 2 internal 10/100 PHYs + 1 external MII/RMII interface for host CPU connection |
| Data Rate | 10/100 Mbps full-duplex per port; no half-duplex auto-negotiation required in managed mode |
| Operating Temp | –40°C to +85°C industrial grade; enables deployment in uncontrolled cabinet environments |
| Supply Voltage | Core: 1.8 V ±5%; I/O: 3.3 V ±10%; separate domains allow mixed-voltage system integration |
| Latency | <15 μs store-and-forward latency at 100 Mbps; critical for real-time industrial protocol bridging |
| VLAN Support | IEEE 802.1Q compliant with 4094 VLAN IDs; enables logical segmentation of OT/IT traffic |
Pinout & Package
ADM6999GA2T1 is housed in a 128-lead Fine Pitch Quad Flat Package (FQFP) with 0.4 mm lead pitch and 14 mm × 14 mm body size. Thermal pad on underside requires soldered thermal connection to PCB ground plane for 1.2 W dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MDIO / MDC | Management Data I/O and Clock | Serial interface to configure PHY registers and monitor link status per port |
| TXD[3:0] / RXD[3:0] | MII Transmit/Receive Data | 4-bit parallel data path for external host interface; supports RMII with reduced pin count |
| REFCLK | Reference Clock Input | 25 MHz clock source for internal PHY timing; must be low-jitter (<100 ps RMS) |
| RESET_N | Active-Low Asynchronous Reset | Hardware reset assertion clears all switch registers and reinitializes PHYs |
| INT_N | Interrupt Output | Open-drain signal indicating link change, error condition, or management event |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Dual PHY + Switch Fabric | Eliminates need for discrete PHYs and external switch IC, reducing BOM count by ≥5 components |
| ARM7TDMI Management Core | Enables local L2/L3 management without host CPU intervention-supports standalone SNMP agent |
| Hardware QoS Queuing | Four priority queues with strict/WRR scheduling ensure deterministic forwarding for time-critical protocols |
| Industrial Temperature Range | Validated operation from –40°C to +85°C supports DIN-rail mounted gateway deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet switch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Microchip KSZ8864RMN | 4-port unmanaged switch with no embedded CPU; requires external microcontroller for SNMP/management | Lacks integrated ARM7 core and VLAN-aware management stack; suitable only for transparent bridging | Select when deterministic latency is primary requirement and management complexity is offloaded externally |
| Marvell 88E6083 | 5-port managed switch with MIPS core; supports Gigabit but requires external PHYs and higher power (2.5 W) | Targets enterprise infrastructure; lacks industrial temp rating and integrated PHYs for compact designs | Choose for multi-gigabit uplink needs where board space and thermal budget permit larger solution |
Compared with KSZ8864RMN and 88E6083, ADM6999GA2T1 uniquely combines integrated dual PHYs, industrial temperature operation, and embedded ARM7 management in a 128-pin FQFP-enabling compact, self-contained, and certifiable edge switch designs.

FAQ
Does ADM6999GA2T1 support Power over Ethernet (PoE)?
No. ADM6999GA2T1 does not integrate PoE functionality or PD interface circuitry. It supports standard 10/100 Ethernet data transmission only. External PoE injectors or midspans must be used if powered device capability is required in the system architecture.
Can ADM6999GA2T1 operate in cut-through switching mode?
No. The device implements store-and-forward switching exclusively. All frames are fully received, CRC-checked, and validated before forwarding-ensuring error-free inter-port transmission but introducing fixed latency overhead.
What boot options are supported for the embedded ARM7TDMI core?
The ARM7 core boots from external SPI flash memory mapped to address 0x00000000. Boot configuration is controlled by hardware strapping pins BOOT[1:0]; no internal ROM or eMMC boot support is provided.
Is JTAG debugging supported on the embedded processor?
Yes. The ARM7TDMI core exposes a standard 20-pin ARM JTAG interface (IEEE 1149.1) on dedicated pins, enabling full-cycle debugging, register inspection, and flash programming using standard ARM-compatible debug probes.
