Interface - Controllers

The Microchip LAN9250/PT is an integrated 10/100 Ethernet controller designed for communications between multiple systems. It provides a low-cost, low-power solution for connecting embedded applications to local Ethernet networks. The LAN9250/PT is a highly integrated Ethernet controller, incorporating the Ethernet medium access control (MAC) and physical layer (PHY) functions into a single device, which reduces component count and lowers power consumption. Using the LAN9250/PT, Ethernet networks can be seamlessly connected with systems and embedded applications, enabling them to easily communicate with each other over the Internet or local networks.

Features and Benefits

The LAN9250/PT is an integrated 10/100 Ethernet controller. It supports IEEE 802.3 Fast Ethernet protocols, including 10BASE-T and 100BASE-TX, as well as legacy technologies like 10-MHz MII and Half- and Full-Duplex. The device also supports the Wake On LAN (WOL) power management feature, which allows for power savings during periods of inactive operation.

The LAN9250/PT is designed to interface directly with a host processor or microcontroller. It provides a direct connection between the host and the Ethernet media, thus removing the need for an external PHY. This reduces the number of components required and lowers power consumption. The device supports both internal and external reset, allowing for simple integration into virtually any system.
