Teridian Semiconductor Corp. announced sample availability of its new Fast Ethernet controller for embedded applications. The 78Q8430 targets consumer electronics and industrial applications that require high performance and ease of use, while limiting the burden on the host processor.

"With the explosive growth of voice, video and data connectivity to the consumer, we believe the 78Q8430, with its minimal host processor overhead capabilities is well positioned to give system designers a cost effective networking solution," said Gerald Fitch, president and CEO of Teridian, in a statement.

The 78Q8430 with integrated hardware IPChecksum and 32Kbytes of configurable SRAM is designed for applications where network throughput performance cannot compromise the low latency or performance requirements of mission critical functions like audio or video processing. Many original equipment manufacturers are adding Ethernet connectivity to their products and finding they may not always be able to afford the additional processing overhead needed to provide a reasonable level of network performance. By providing dedicated hardware support for processor intensive functions and large 32Kbytes buffers, system designers using the 78Q8430 can quickly achieve network throughput performance without spending significant development hours optimizing code.

At the network side, the 78Q8430 interfaces to UTP cabling via a transformer and RJ45 connector. With full 802.3 auto-negotiation and support for HP Auto-MDIX, connection with any LAN device is assured.

Samples of the 78Q8430, as well as evaluation kits are already available, with production volumes expected later this year. In addition, device drivers for the 78Q8430 are available from Teridian for multiple processors and operating systems.
