LAN9218-MT

Controllers Overview

The LAN9218-MT is a single-chip 10/100 Ethernet controller integrating an IEEE 802.3 MAC and PHY with HP Auto-MDIX support. It features a simple SRAM-like host bus interface compatible with 16-bit or 32-bit embedded CPUs, supporting both big-endian and little-endian architectures. The device includes configurable transmit and receive FIFOs totaling 16 KBytes to minimize CPU overhead and packet loss. It operates on a single 3.3V power supply with 5V tolerant I/O and supports commercial temperature ranges from 0°C to +70°C.

Controllers Feature Summary

• Integrated 10/100 Ethernet MAC and PHY with HP Auto-MDIX and auto-negotiation capabilities
• SRAM-like slave interface for glue-less connection to most common microprocessors and microcontrollers
• Configurable 16-KByte internal FIFO memory architecture to reduce overrun conditions
• Comprehensive power management modes including Wake-on-LAN and Magic Packet detection

Controllers Applications

• High-end cable, satellite, and IP set-top boxes
• Video distribution systems and multi-room PVRs
• Digital video recorders and DVD recorder/players
• Home gateways and digital media clients/servers
• Wireless routers and access points

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure that any required external components, such as magnetics and passive components around the magnetics, are updated to support HP Auto-MDIX functionality during integration.

Controllers Selection Notes

Select this component for embedded applications requiring high performance with low CPU overhead. It serves as a direct footprint and register-compatible replacement for previous generation LAN9118 family devices, allowing for driver reuse while offering enhanced features like integrated PHY and larger buffer memory.

Controllers Part Context

The LAN9218 belongs to Microchip's line of non-PCI Ethernet controllers designed for embedded environments. It provides a platform-independent solution that simplifies system design by combining MAC and PHY functions into a single chip, reducing board space and component count compared to discrete solutions.

Controllers Replacement Considerations

Public confirmed substitute part numbers include LAN9215-MT and LAN9217-MT.
