Ethernet Controller 10/100 Base-T/TX PHY Parallel Interface 128-QFP (14x20)
The LAN91C111-NU is a 10/100 non-PCI Ethernet Controller 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 analogue/digital device that implements the MAC and PHY portion of the CSMA/CD protocol at 10 and 100Mbps. The design will also minimize data throughput constraints utilizing a bus host interface. The total internal memory FIFO buffer size is 8kB, which is the total chip storage for transmit and receive operations. The LAN91C111 is software compatible with the LAN9000 family of products.
