The LAN9210 and LAN9211 are full-featured, single-chip, non-PCI 10/100 Ethernet controllers designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9210 has been architected to provide one of the best price-performance ratios for any 16-bit applications with medium-performance requirements. The LAN9211 has been specifically designed for high-performance, 16-bit applications. Both are fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and support HP Auto-MDIX.

The LAN9210 and LAN9211 include an integrated Ethernet MAC/PHY with a high-performance SRAM-like slave interface. The simple, yet highly functional host bus interface provides a glue-less connection to most common 16-bit microprocessors and microcontrollers as well as 32-bit microprocessors with a 16-bit external bus. The integrated checksum offload engines enable the automatic generation of the 16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. They also include large transmit and receive data FIFOs to accommodate high latency applications. In addition, the memory buffer architecture allows highly efficient use of memory resources by optimizing packet granularity.
