LAN9220 & LAN9221 10/100 Ethernet Controllers
Microchip Technology LAN9220 and LAN9221 10/100 Ethernet Controllers are designed for embedded applications where performance, flexibility, ease of integration, and system cost control are required. The LAN9220 and LAN9221 are fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and support HP Auto-MDIX. The variable voltage I/O signals of the LAN9220 accommodate lower voltage I/O signalling without the need for voltage level shifters. The LAN9220 provides an optimized price/performance ratio, and the LAN9221 is optimized for high-performance applications.
