Product Summary
The SMSC LAN91C113-NC is a feast fast ethernet controller. For this third generation of products, flexibility and integration dominate the design requirements. The LAN91C113-NC 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 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 SMSC LAN91C113-NC is software compatible with the LAN9000 family of products. The LAN91C113-NC can automatically configure itself for 100 or 10 Mbps and Full or Half Duplex operation with the on-chip Auto-Negotiation algorithm. The LAN91C113-NC is ideal for media interfaces for embedded application desiring Ethernet connectivity as well as 100Base-TX/10Base-T adapter cards, motherboards, repeaters, switching hubs. The LAN91C113-NC operates from a single 3.3V supply. The inputs and outputs of the host Interface are 5V tolerant and will directly interface to other 5V devices.
