10/100 CONTROLLER W/ GENERIC 8/16-BIT BUS I/F

The KSZ8852 product line consists of industrial capable Ethernet switches, providing integrated communication for a range of Industrial Ethernet and general Ethernet applications. The KSZ8852 product enables distributed, daisy-chained topologies preferred for industrial Ethernet networks. Conventional centralized (i.e., star-wired) topologies are also supported for fault tolerant arrangements. A flexible 8 or 16-bit general bus interface is provided for interfacing to an external host processor. The wire-speed, store-and-forward switching fabric provides a full complement of QoS and congestion control features optimized for real-time Ethernet. The KSZ8852 product is built upon Micrel’s industryleading Ethernet technology, with features designed to offload host processing and streamline your overall design: Wire-speed Ethernet switching fabric with extensive filtering Two integrated 10/100BASE-TX PHY transceivers, featuring the industry’s lowest power consumption Full-featured QoS support Flexible management options that support common standard interfaces. The KSZ8852 includes all the functions of a 10/100BASE-T/TX switch system which combines a switch engine, frame buffer management, address look-up table, queue management, MIB counters, media access controllers (MAC) and PHY transceivers Non-blocking store-and-forward switch fabric assures fast packet delivery by utilizing 1024 entry forwarding table Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port MIB counters for fully compliant statistics gathering - 34 counters per port Loopback modes for remote failure diagnostics Two integrated IEEE 802.3 / 802.3u compliant Ethernet transceivers supporting 10BASE-T and 100BASE-TX On-chip termination resistors and internal biasing for differential pairs to reduce power Three internal media access control (MAC) units 2Kbyte Jumbo packet support VLAN ID tag/untag options on per port basis Fully compliant with IEEE 802.3 / 802.3u standards Power consumption less than 0.5W 64-pin (10mm × 10mm) lead free (ROHS) LQFP package with heat exposed ground paddle for low thermal resistance
