LAN9117-MT

Controllers Overview

The LAN9117-MT is a single-chip 10/100 Ethernet controller from the LAN9118 family, optimized for medium-high performance embedded applications. It integrates an IEEE 802.3 compliant MAC and PHY, supporting 10BASE-T and 100BASE-TX speeds in full or half-duplex modes. The device features a 16-bit SRAM-like host interface compatible with most 16-bit microprocessors and 32-bit processors exposing a 16-bit bus. It includes a large configurable FIFO memory buffer capable of storing over 200 packets to eliminate dropped packets. Power management supports Wake on LAN, Magic Packet, and Link Status Change events. The component operates within a temperature range of 0 to 70 °C and is housed in a low-profile 100-pin TQFP package.

• Supports comprehensive power management including Wake on LAN and Magic Packet detection

Controllers Applications

• Medium-range cable, satellite, and IP set-top boxes
• Digital video recorders and DVD recorders/playbacks
• High-definition televisions and digital media clients/servers
• Home gateways and Video-over IP solutions
• Wireless routers and access points

Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product identification system to ensure correct package type and temperature grade. Confirm that the required documentation, such as the datasheet revision history and any applicable errata sheets, is obtained directly from official Microchip channels prior to design finalization.

Controllers Selection Notes

Select this component for embedded designs requiring a non-PCI Ethernet solution with minimal CPU overhead. Ensure the host processor supports a 16-bit asynchronous SRAM interface. Verify that the application environment stays within the specified commercial temperature range and that the 3.3V power supply with 5V tolerant I/O meets system voltage requirements.

Controllers Part Context

The LAN9117-MT belongs to the LAN9118 family of Ethernet controllers, sharing pin compatibility with other members of the series. It is designed specifically for medium-to-high performance applications where system cost and integration simplicity are critical. The device serves as a peripheral chip translating parallel host data into Ethernet packets for network transmission.

Controllers Replacement Considerations

Other members of the LAN9118 family are pin-compatible and may serve as functional replacements depending on specific feature requirements or availability. Consult the official product selection guide to identify equivalent parts within the same family that match the desired performance tier and interface configuration.
