LAN9215 pdf datasheet (10/100

The LAN9215 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 LAN9215 has been architected to provide the best price-performance ratio for any 16-bit
application with medium performance requirements. The LAN9215 is fully IEEE 802.3 10BASE-T and
802.3u 100BASE-TX compliant, and supports HP Auto-MDIX.
The LAN9215 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 with a
16-bit external bus. The LAN9215 includes large transmit and receive data FIFOs to accommodate
high latency applications. In addition, the LAN9215 memory buffer architecture allows the most efficient
use of memory resources by optimizing packet granularity.
