Product details
Overview
ADM6995LAAT1 from Infineon Technologies is a 10/100 Ethernet switch controller IC in 128-pin QFP package, supporting IEEE 802.3u Fast Ethernet, integrated MAC and PHY interface, and 16-bit host bus interface. It enables embedded network edge switching in industrial gateways requiring deterministic latency and low-power operation.
For engineers reviewing the ADM6995LAAT1 datasheet, ADM6995LAAT1 pinout, ADM6995LAAT1 application, or ADM6995LAAT1 equivalent, key selection criteria include its 10/100 Mbps dual-port capability, integrated MII/RMII interface support, 3.3 V I/O compatibility, and QFP-128 thermal and routing constraints.
Technical Context
The ADM6995LAAT1 integrates two independent 10/100 Mbps Ethernet MACs with embedded packet buffer memory and supports both MII and RMII physical layer interfaces. It implements full-duplex flow control, VLAN tagging per port (IEEE 802.1Q), and hardware-based priority queuing with four configurable transmit queues per port.
It features an asynchronous 16-bit parallel host interface with programmable wait-state control, supports little-endian data transfer, and includes dedicated interrupt signaling for link status change, packet reception, and transmit completion events.
Key Specifications

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-LF | 6-port managed switch with integrated PHYs; requires external clock oscillator and lacks RMII mode | Targeted at multi-node aggregation rather than dual-port edge bridging | Choose when >2 ports and PHY integration are required; avoid if board space or RMII routing is constrained |
| Microchip LAN9252 | Dual-port EtherCAT slave controller with fixed 100 Mbps rate and no VLAN support | Optimized for motion control synchronization, not general-purpose Ethernet bridging | Prefer for EtherCAT-specific deployments; unsuitable for IEEE 802.1Q or mixed-speed (10/100) use cases |
Compared with Marvell 88E6060-B0-LF and Microchip LAN9252, the ADM6995LAAT1 uniquely balances dual-port flexibility, RMII/MII adaptability, and hardware VLAN offload-making it optimal for compact, standards-compliant industrial edge switches where PHY independence and deterministic latency are critical.

FAQ
Does ADM6995LAAT1 support Gigabit Ethernet?
No. The ADM6995LAAT1 is strictly a 10/100 Mbps Fast Ethernet switch controller. It does not implement 1000BASE-T PHY or MAC functionality, nor does its datasheet reference any gigabit-capable modes or optional firmware upgrades. Its MII/RMII interface is defined only for 10/100 operation.
Can ADM6995LAAT1 operate with a 1.8 V host interface?
No. The host interface I/O voltage is fixed at 3.3 V ±0.3 V, as specified in the Absolute Maximum Ratings and DC Characteristics tables. Driving HADDR/HDATA lines at 1.8 V violates input threshold requirements and risks functional failure or latch-up.
Is external clock required for RMII operation?
Yes. RMII mode requires a 50 MHz reference clock applied to the REFCLK pin. This clock must meet jitter and duty cycle specifications outlined in Section 6.2 of the ADM6995 datasheet; no internal PLL generates this signal.
Does ADM6995LAAT1 support JTAG debugging?
No. The device does not include JTAG TAP controller or boundary-scan logic. Debugging is limited to register reads/writes via the 16-bit host interface and interrupt-driven status monitoring; no on-chip debug port or SWD interface is implemented.
