The LAN91C96 is a single-chip 10/100 Mbps Ethernet controller with integrated MAC and PHY, manufactured by SMSC Corporation (now Microchip Technology). It is designed to provide a simple and cost-effective solution for adding Ethernet connectivity to embedded systems.

Applications:

• Embedded systems: Used in network printers, industrial control systems, and point-of-sale (POS) terminals.
• Consumer electronics: Found in set-top boxes, network-attached storage (NAS) devices, and gaming consoles.
• Networking equipment: Employed in low-end routers, switches, and network interface cards (NICs).
• Industrial automation: Utilized in programmable logic controllers (PLCs), human-machine interfaces (HMIs), and data acquisition systems.

Features:

• Integrated MAC and PHY: Single-chip solution with integrated Media Access Controller (MAC) and Physical Layer (PHY).
• 10/100 Mbps Ethernet Support: Supports both 10BASE-T and 100BASE-TX Ethernet standards.
• PCI Interface: Connects to the host system via a PCI interface.
• Auto-Negotiation: Automatically detects and configures the link speed and duplex mode.
• Auto-MDIX: Supports automatic MDI/MDIX crossover, eliminating the need for crossover cables.
• Flow Control: Supports IEEE 802.3x flow control for reliable data transmission.
• Diagnostic Features: Includes built-in diagnostic features for easy troubleshooting.

Benefits:

• Simplified Design: Integrated MAC and PHY simplifies system design and reduces component count.
• Automatic Configuration: Auto-negotiation and auto-MDIX eliminate the need for manual configuration, reducing development time.
• Reliable Performance: Supports flow control and includes diagnostic features for reliable data transmission.
• Cost-Effective Solution: Offers a cost-effective solution for adding Ethernet connectivity to embedded systems.

Additional Details:

The LAN91C96 operates from a 3.3V power supply and is available in various package options, including PQFP (Plastic Quad Flat Pack). It is supported by a comprehensive suite of software drivers and development tools. The controller is designed to meet industry standards for electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection.
