The DM9161CIEP is a single-chip Fast Ethernet MAC controller with a Media Independent Interface (MII). It is designed to provide a high-performance and cost-effective solution for integrating Ethernet connectivity into a wide range of embedded systems. It is manufactured by Davicom. As an END-OF-LIFE product, it is important to carefully consider long-term availability and potential replacements.

Applications

• Embedded Systems Networking
• Network Interface Cards (NICs)
• Ethernet-enabled devices such as printers and storage devices
• Industrial control systems
• Set-top boxes and media players

Features

• Compliant with IEEE 802.3u 100Base-TX and 10Base-T standards
• Supports full-duplex and half-duplex operation
• Integrated 10/100 Mbps transceiver
• MII (Media Independent Interface) for flexible PHY selection
• Supports auto-negotiation for automatic speed and duplex selection
• Built-in FIFO buffers for transmit and receive data
• Supports VLAN tagging (IEEE 802.1Q)
• Supports checksum offload for reduced CPU overhead
• Power management features for low power consumption

Benefits

• Provides a cost-effective solution for adding Ethernet connectivity to embedded systems
• Simplifies system design with integrated MAC and PHY functionality
• Ensures interoperability with existing Ethernet networks
