Ethernet Solutions

Ethernet capability is now available to the worldwide automotive market with the launch of Micrel's family of AEC-Q100 Automotive qualified Ethernet devices. This device family offers complete flexibility when interfacing Ethernet to any desired processor via MII, RMII, SNI or PCI bus. Solutions are available from a single Ethernet port up to three Ethernet Ports. The ICs, the KSZ8041NL AM - Single-Port Fast Ethernet Physical Layer Transceiver, KSZ8842-PMBL AM - 3-Port Managed Fast Ethernet Switch with PCI, and KSZ8893MQL AM - 3-Port Managed Fast Ethernet Switch with MII/RMII, are the industry's first and only AEC-Q100 Automotive qualified Ethernet devices on the market today.

In this emerging market, Micrel is the first to supply Ethernet devices to a car. Ethernet is initially being introduced for ODB (on board diagnostics) and software memory download. Current methods have proven too slow to re-program the increasing amount of electronics in the car; Ethernet is faster, cheaper and offers the same common interface used by the PC / laptop and office, industrial and home networks. The next step is using Ethernet as the backbone for next generation automotive multi-media networks carrying 'live' traffic.

"With billions of consumer electronics and office products sold every year and energy conservation fast moving from a worldwide concern into crisis mode, it was crucial that the next generation of ICs offer breakthrough approaches to saving power. Micrel's Green initiative involves all aspects of design, engineering, marketing and other disciplines to bring to market exceptional and innovative methods for saving power," noted Andrew Cowell, Micrel's vice president of marketing for analog products. "These new devices demonstrate Micrel's on-going commitment to providing its customers the most innovative and advanced ICs on the market today. APEC provides Micrel with a synergistic and complementary venue for showcasing its commitment to green strategies and Corporate product development."
