SMSC has broadened its portfolio of Ethernet technology solutions with the introduction of several new switches, PCI Ethernet controllers and USB to Ethernet controllers for the embedded market.

Among these new products are the LAN931x family of multiport embedded Ethernet switches, the high-performance LAN9420 PCI Ethernet controller and the LAN9500 USB to Ethernet controller, each designed to meet the complex network connectivity requirements of consumer, commercial and industrial applications. These devices promise flexibility and robust performance and offer customers a larger set of options to choose from when designing Ethernet connectivity into next-generation applications.

"SMSC's switching products solve the increasing need of audio/video content sharing in the connected home using Ethernet networking connectivity between consumer electronic devices," said Rob Zecha, divisional VP of marketing for networking products at SMSC. "Also designed for low-cost connectivity to a network, our USB to Ethernet controller offers system designers a flexible means of Ethernet attachment using a standards-based USB interface."

The new LAN931x family of embedded Ethernet switches supports the increasing growth of networked devices in home consumer electronics. These devices supply system designers with two- and three-port switching technology to solve network connectivity requirements using both 16bit and 32bit non-PCI and MII interfaces. In addition to switching capability, SMSC has incorporated the IEEE1588 Precision Time Protocol into its switch for time-critical applications.

In response to the increasing trend of PCI in embedded applications, the LAN9420 PCI MAC/PHY Ethernet controller integrates SMSC's scatter-gather based DMA engine to give embedded system designers a high-performance controller option that reduces overall processor loading.

The LAN9500 USB to Ethernet controller allows developers to deliver Ethernet connectivity while leveraging the proliferation of USB 2.0 technology. In addition to the LAN9500's small form factor, SMSC's system solution provides designers with an attractive BOM by minimizing the number of external components needed.

SMSC's LAN931x Ethernet switch and LAN9420 Ethernet controller devices are both available in a 128-pin VTQFP (14mm x 14mm) package. The LAN9500 USB to Ethernet controller is offered in a 56-pin QFN (8mm x 8mm) package. All devices support both commercial and industrial temperature ranges. Samples are available with production supplies expected in the second half of 2008.
