SMC91C94QFP

Product Summary

The SMC91C94QFP is a VLSI Ethernet Controller that combines ISA and PCMCIA interfaces, as well as an interface to a companion modem chip set, in one chip. The SMC91C94QFP integrates all the MAC and physical layer functions as well as the packet RAM needed to implement a high performance 10BASE-T (twisted pair) node. For 10BASE5 (thick coax), 10BASE2 (thin coax), and 10BASE-F (fiber) implementations, the SMC91C94QFP interfaces to external transceivers via its AUI port. Only one additional IC is required on most applications.
