The company said that the IC comes with low power dissipation, efficient power management and QoS features.
Micrel said that its AEC-Q100 qualified (for automotive applications) device offers low power consumption and power management schemes that accommodate ‘green’ system design requirements.
According to the company, the KSZ8873MLL AM’s small package size (64-pin LQFP) and high integration (on-chip LDO) reduce system cost and simplify system design.
In addition, the Port 1 and Port 2 by-pass mode allows the device connected to the MII interface so it can enter a power saving mode without impacting the normal switch operation. Enhanced QoS support (4-queue traffic prioritization and source address filtering) facilitates implementation of QoS policies in the ethernet ring network for automotive applications.
The chip features source address filtering, rate limiting per queue and Auto-MDI/MDIX that eliminates the need for cross-over cable, thus reduces installation costs, the company added.
J Lin, vice president of ethernet products at Micrel, said: “As ethernet significantly reduces the cost of ownership in the automobile, the global automotive community is quickly embracing ethernet as the defacto network platform in a car.
”This new switch product, with its low power and small footprint, offers customers the ideal solution to build the ethernet backbone for the multimedia network in the next generation of vehicles.”
KSZ8873MLL AM is currently available in volume quantities, and pricing is available upon request.
