Add To BomLAN91C111-NU General Description
The Microchip LAN91C111 is designed to facilitate the implementation of a third generation of Fast Ethernet connectivity solutions for embedded applications. For this third generation of products, flexibility and integration dominate the design requirements. The LAN91C111 is a mixed signal Analog/Digital device that implements the MAC and PHY portion of the CSMA/CD protocol at 10 and 100 Mbps. The design will also minimize data throughput constraints utilizing a 32-bit, 16-bit or 8-bit bus Host interface in embedded applications.
The total internal memory FIFO buffer size is 8 Kbytes, which is the total chip storage for transmit and receive operations.
The Microchip LAN91C111 is software compatible with the LAN9000 family of products.
