Descriptions:

The AL981 is a single-chip Fast Ethernet controller designed for PCI-based systems. It integrates both the MAC (Media Access Control) and PHY (Physical Layer) functions, providing a cost-effective solution for networking applications. It supports auto-negotiation for seamless compatibility with 10BASE-T and 100BASE-TX networks.

Features:

• Integrated MAC & PHY – Reduces external component requirements.
• Auto-Negotiation – Automatically selects the best speed (10/100 Mbps) and duplex mode.
• PCI Bus Master Support – Enhances data transfer efficiency.
• Full-Duplex Support – Enables simultaneous two-way communication.
• Wake-on-LAN (WoL) – Allows remote wake-up of the system via a network signal.
• Low Power Consumption – Optimized for energy efficiency.
• LED Indicators – Supports link/activity and speed status LEDs.
• Driver Support – Compatible with major operating systems, including Windows and Linux.

The AL981 is commonly found in network interface cards (NICs) and embedded systems requiring reliable Ethernet connectivity.
