LAN9500AI-ABZJ Product Features
High-speed data transmission: The LAN9500AI-ABZJ supports USB 2.0 high-speed transmission mode, achieving data transfer rates of up to 480Mbps, meeting the demands of modern network applications for high-speed data transmission. It is also backward compatible with USB 1.1 devices, ensuring seamless compatibility with older equipment.
Dual Ethernet Ports: The LAN9500AI-ABZJ provides two 10/100 Mbps Ethernet ports, enabling network connectivity for multiple devices. This dual-port design not only enhances network flexibility but also improves network redundancy, providing higher reliability for mission-critical applications.
Low-power design: The chip employs advanced low-power technology, ensuring high performance while significantly reducing power consumption. In normal operating mode, the LAN9500AI-ABZJ consumes only [X] mW, offering a notable energy-saving advantage over comparable products. This is particularly beneficial for devices requiring prolonged operation, as it reduces energy costs, minimises heat dissipation requirements, and improves device stability and lifespan.
High integration: The LAN9500AI-ABZJ integrates multiple functional modules, including MAC, PHY, and USB controllers, significantly reducing the number of external components and PCB area. This high-integration design not only simplifies system complexity and reduces costs but also enhances system reliability and interference resistance. Additionally, it supports multiple power management modes, automatically adjusting power consumption based on different operating states to further optimise system energy efficiency.
Excellent electromagnetic compatibility: The LAN9500AI-ABZJ was designed with electromagnetic compatibility in mind, employing advanced shielding technology and optimised circuit layout to effectively reduce electromagnetic interference. It meets stringent industrial-grade electromagnetic compatibility standards, ensuring stable operation in complex electromagnetic environments without interfering with other devices or being affected by external interference. This is critical for applications with high electromagnetic compatibility requirements, such as industrial automation and medical equipment.
Flexible configuration options: The LAN9500AI-ABZJ offers a wide range of configuration options, allowing users to flexibly configure it via register programming according to actual needs. For example, different operating modes, rates, flow control strategies, and interrupt priorities can be set. This flexibility enables the LAN9500AI-ABZJ to adapt to various complex network environments and application scenarios, meeting the personalised needs of different users.
Robust network management features: The chip integrates multiple network management features, such as link status detection, flow control, and VLAN support. The link status detection feature monitors network connection status in real time. Upon detecting a link failure, it promptly issues an alert and takes appropriate measures. The flow control function automatically adjusts the data transmission rate based on network traffic volume to prevent network congestion and ensure smooth network operation. The VLAN support function allows users to divide the network into multiple virtual local area networks, enabling isolation and secure access between different networks, thereby enhancing network security and management efficiency.
