General Description
The LAN9115 is a full-featured, single-chip 10/100 Ethernet controller designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9115 has been architected to provide the best price-performance ratio for any 16-bit application with medium performance requirements. The LAN9115 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.
The LAN9115 includes an integrated Ethernet MAC and 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 exposing a 16-bit external bus. The LAN9115 includes large transmit and receive data FIFOs to accommodate high-latency applications. In addition, the LAN9115 memory buffer architecture allows the most efficient use of memory resources by optimizing packet granularity.
