The LAN9250I/ML is a high-performance, single-chip IPv4/v6 two-port Ethernet controller. It integrates complete 10/100/1000 Ethernet MAC and physical layer functions, including Embedded frame buffer, CRC calculation, preamble generation, back pressure, IEEE 802.3az EEE, low-power modes, wake-on-LAN, suspended detect, and AMBA bus interface for extending additional throughput and ability to further reduce the implementation cost. The LAN9250I/ML supports both MII and RMII for connecting the MAC to the external PHY.

Application Field

The LAN9250I/ML offers a versatile set of features for a range of markets, such as factory automation, printing, consumer, networking equipment, medical, and automotive. Its low power consumption and wide temperature range make the device well suited for embedded applications.

The LAN9250I/ML is an efficient and cost-effective solution for ethernet-connected embedded applications. It is ideal for system designers who need to add ethernet connections to products, such as barcode readers, gaming machines, and vending machines that depend on reliable, secure communication. It is also suitable for display systems, data acquisition, access control and 24/7 surveillance systems.

Working Principle

The LAN9250I/ML works by providing an embedded frame buffer, CRC calculation and preamble generation. The embedded frame buffer is double buffered, allowing register level access to the frame and providing a flexible architecture for the development of complex network applications. The CRC calculation function allows for verification of the contents of a packet. The preamble generation function generates a preamble, allowing the sender to identify its packet in the destination station.

The LAN9250I/ML also provides back pressure support which helps reduce latency and collision behavior over congested links. It supports IEEE 802.3az EEE for optimized power management, low-power operation, and wake-on-LAN for remote operation. It has an AMBA bus interface which allows for extension of throughput and reduction of implementation costs. The LAN9250I/ML also supports both MII and RMII for connecting the MAC to the external PHY.

In addition, the LAN9250I/ML supports advanced features such as error injection, flow control configuration, multi-thread support, and address filtering. The device is protected against ESD, Electro-Static Discharge, and Electro-Magnetic Interference, EMI. It is also compliant with the latest industry standards including IEEE 802.3, IEEE 802.3af Power over Ethernet, IEEE 802.3ab 1000BASE-T, IEEE 802.3ad Link Aggregation, and IEEE 802.3u Fast Ethernet.

Conclusion

The LAN9250I/ML single chip two-port Ethernet controller is a reliable, cost-effective solution that offers a versatile set of features for a range of markets. It is an ideal device for embedded applications, such as barcode readers, gaming machines, and vending machines, due to its low power consumption and wide temperature range. The device is also compliant with the latest industry standards and supports advanced features, such as error injection, flow control configuration and address filtering. It provides an embedded frame buffer, CRC calculation and preamble generation for efficient operation. In conclusion, the LAN9250I/ML is an ideal solution for integrating the Ethernet into embedded applications.
