MT9171AN1

Telecom Overview

The MT9171AN1 is a non-PCI Ethernet controller from the LAN9118 family, designed for mid-to-high performance applications. It integrates a 10/100 Base-T/TX PHY with an Ethernet MAC and provides a 16-bit parallel interface compatible with most embedded CPUs. The device features internal buffer memory to support automatic or host-triggered flow control, minimizing packet loss. It operates within a voltage range of 3.0 V to 3.6 V and supports interfaces including SPI, UART, USART, and USB alongside its primary parallel bus. The component is housed in a 100-TQFP package and is suitable for wired networking, IP set-top boxes, and home gateways.

• Wireless Routers and Access Points

Telecom Procurement Notes

Verify the specific suffix 'AN1' against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target 16-bit CPU interface requirements. Check for moisture sensitivity levels and reflow soldering profiles if surface mount assembly is planned. Confirm availability through authorized distributors as lead times may vary.

Telecom Selection Notes

Select this component when a low-pin-count, non-PCI Ethernet solution is required for embedded systems. It is appropriate for designs needing integrated PHY functionality without external transceivers. Consider the 16-bit interface width relative to system bus speed. Evaluate power consumption modes if battery operation or low-power standby states are critical design constraints.

Telecom Part Context

This part belongs to the LAN9118 family of Ethernet controllers. It shares architectural similarities with other members like the LAN9117, offering similar integration levels but potentially differing in package options or specific interface configurations. The family is targeted at cost-sensitive, space-constrained networking applications requiring reliable 10/100 Mbps connectivity.

Telecom Replacement Considerations

The LAN9117 is a confirmed public substitute within the same product family. Verify that the pinout and register compatibility between the MT9171AN1 and the LAN9117 meet the specific design requirements before substitution.
