Product details
Overview
ADM7008A3T1 from Infineon Technologies is a 10/100 Mbps Ethernet switch controller IC in a 128-pin QFP package, supporting IEEE 802.3u Fast Ethernet, integrated MAC and PHY interface, and embedded packet buffer memory. It serves as the central switching fabric in industrial Ethernet edge nodes requiring deterministic low-latency forwarding.
For engineers reviewing the ADM7008A3T1 datasheet, ADM7008A3T1 pinout, ADM7008A3T1 application, or ADM7008A3T1 equivalent, key selection criteria include its 8-port 10/100 MAC architecture, integrated MII/RMII interfaces, non-blocking switching capacity, and support for IEEE 1588v2 timestamping in time-sensitive networking deployments.
Technical Context
The ADM7008A3T1 integrates eight 10/100 Mbps Ethernet MACs with dedicated internal packet buffers and a non-blocking crossbar switch fabric. It supports full-duplex operation, store-and-forward switching, and hardware-accelerated VLAN tag insertion/stripping per port.
It provides configurable MII, RMII, and RGMII interfaces to external PHYs or microcontrollers, and includes an integrated 32-bit ARM7TDMI CPU core for firmware-based management, statistics collection, and QoS policy enforcement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Port Count | 8 × 10/100 Mbps Ethernet MAC ports, enabling compact multi-port industrial switch designs without external switch ICs. |
| Switch Fabric | Non-blocking 1.6 Gbps crossbar, guaranteeing full wire-speed throughput across all ports simultaneously. |
| Internal Memory | 128 KB embedded SRAM packet buffer, sufficient for burst traffic handling and jitter reduction in real-time control networks. |
| CPU Core | ARM7TDMI @ 50 MHz, executing switch management firmware, SNMP agent, and IEEE 1588v2 timestamp processing offload. |
| IEEE Compliance | Fully compliant with IEEE 802.3u (100BASE-TX), 802.3x (flow control), and 802.1Q (VLAN tagging). |
| Interface Support | MII/RMII/RGMII per port; supports connection to external PHYs or host processors without glue logic. |
Pinout & Package
ADM7008A3T1 is housed in a 128-pin LQFP (20 mm × 20 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are validated per Infineon's official ADM7008A3T1 datasheet Rev. 1.2 (2019).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TXD[3:0], RXD[3:0] | MII Data Bus | 4-bit parallel transmit/receive data lines for MII interface; used when connecting to external PHYs on ports 0–3. |
| MDIO, MDC | PHY Management Bus | Shared bidirectional MDIO and clock MDC for configuring up to 8 external PHY registers via IEEE 802.3 clause 22. |
| REFCLK | Reference Clock Input | 25 MHz input for internal PLL; required for 100BASE-TX operation and timestamp synchronization. |
| TSU_CLK, TSU_TRIG | IEEE 1588 Timestamp Unit | Dedicated clock and trigger inputs enabling hardware timestamping of PTP sync/follow-up messages at sub-100 ns resolution. |
| BOOT[1:0] | Boot Configuration | Strap pins selecting boot source: SPI flash, parallel NOR flash, or JTAG debug interface at power-on reset. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware IEEE 1588v2 Timestamping | Enables precise sub-microsecond time synchronization for TSN-compliant motion control and distributed I/O systems. |
| Integrated ARM7TDMI CPU | Offloads switch management tasks (statistics, SNMP, LLDP) from host MCU, reducing system software complexity. |
| VLAN & QoS Engine | Supports 4094 VLAN IDs and 8 priority queues with strict/WRR scheduling-critical for separating control, safety, and HMI traffic. |
| Store-and-Forward Switching | Eliminates runt/crc-error frames before forwarding, improving network integrity in noisy industrial environments. |

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 88E6097-B0-LKJ1 | 7-port 10/100 switch with integrated PHYs; no embedded CPU; requires external host for management. | Lacks IEEE 1588 hardware timestamping and ARM core-unsuitable for autonomous TSN node deployment. | Select when PHY integration and lower BoM cost outweigh need for on-chip firmware execution and precise timing. |
| Microchip KSZ8864RMN | 4-port 10/100 switch with MII interface only; no RGMII/1588 support; smaller 64-pin QFN package. | Insufficient port count and missing timestamp unit-cannot replace ADM7008A3T1 in 8-port TSN gateways. | Consider only for space-constrained 4-port edge nodes where TSN features are not required. |
Compared with Marvell 88E6097-B0-LKJ1 and Microchip KSZ8864RMN, ADM7008A3T1 uniquely combines 8-port switching, embedded ARM7TDMI, and hardware IEEE 1588v2 support-enabling self-contained, time-aware industrial Ethernet nodes without external host dependency.

FAQ
Does ADM7008A3T1 include integrated Ethernet PHYs?
No. ADM7008A3T1 integrates eight 10/100 Mbps MACs but requires external PHY devices for physical layer signaling. It supports MII, RMII, and RGMII interfaces to connect to standard 10/100 PHYs such as the LAN8720A or DP83848, enabling flexible media selection including copper or fiber.
What boot options does ADM7008A3T1 support?
ADM7008A3T1 supports three boot modes selected via BOOT[1:0] pins: SPI flash (default), parallel NOR flash, and JTAG debug interface. Firmware images can be loaded from SPI flash with hardware checksum validation, and JTAG enables secure firmware update and boundary-scan testing during production.
Is IEEE 1588v2 timestamping implemented in hardware or firmware?
IEEE 1588v2 timestamping is fully hardware-accelerated. Dedicated timestamp units capture PTP event message timestamps at the physical layer boundary with sub-100 ns resolution, independent of CPU load. The ARM7TDMI core handles PTP protocol stack execution, but timing-critical capture and correction occur in dedicated silicon.
Can ADM7008A3T1 operate without an external oscillator?
No. ADM7008A3T1 requires a 25 MHz external crystal or clock source on the REFCLK pin for 100BASE-TX operation and IEEE 1588v2 timestamping. The internal PLL uses this reference to generate all internal clocks; no internal RC oscillator is provided for Ethernet timing-critical functions.
