Part Number : LAN9221
Function : High-Performance 16-bit Non-PCI 10/100 Ethernet Controller with Variable Voltage I/O
Package : QFN 56 Pin type
Maker : SMSC , Microchip
Pinouts : 
Description :
The LAN9221 / LAN9221i 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 LAN9221/LAN9221i has been specifically designed to provide high performance and throughput for 16-bit applications. The LAN9221/LAN9221i is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and supports HP Auto-MDIX. The variable voltage I/O signals of the LAN9221/LAN9221i accommodate lower voltage I/O signalling without the need for voltage level shifters.
Features
1. Optimized for high performance applications
2. Efficient architecture with low CPU overhead
3. Easily interfaces to most 16-bit embedded CPU’s
