Product Summary

The DP83934CVUL-25 is a SONIC-T Systems-Oriented Network Interface Controller with Twisted Pair. The DP83934CVUL-25 a second-generation Ethernet Controller designed to meet the demands of today’s high-speed 32- and 16-bit systems. Its system interface operates with a high speed DMA that typically consumes less than 5% of the bus bandwidth. Selectable bus modes provide both big and little endian byte ordering and a clean interface to standard microprocessors.
