 MCS7832 -- Low-Pin-Count USB 2.0 to 10/100M Fast Ethernet Controller

The MCS7832 USB to 10/100 Ethernet Controller is a unique solution to interface 10/100 Base-T Ethernet devices to the Universal Serial Bus (USB-2.0). This device has been specifically designed to provide a simple, low cost solution to communicate with applications needing plug-and play 10/100 Ethernet connectivity with minimal design time. This is accomplished by its highly integrated functionality, robust software suite, WHQL and USB-IF certification, low pin-count and high performance. It provides internal buffering to enable parallel operations from USB ports on the host side, and MAC ports on the Ethernet side. It also provides a serial interface for an EEPROM for storing the MAC-ID, VID, PID, and other configurable settings.
