FEATURES

? Monolithic intelligent octal 10/100 Ethernet Switch Port Controller.

? Integrates eight 10/100 MACs that connect to physical layer devices over standard IEEE 802.3u MIIs.

? Supports the Gigabit EXACT Bus Protocol for device interconnect.

? May be used alone or in combination with other devices to build high density 10/100 switches.

? PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 96 10/100 Mbit/s ports.

? Layer 2 line rate address lookup capability for all Ethernet port configurations supported.

? Store-and-forward switching using output associated input buffering for efficient memory use without Head Of Line (HOL) blocking.

? Supports 8,000 MAC addresses.

? 1022 multicast groups available. Bitmask per group defines membership.

? EXACT Bus is compatible with common serial devices for simple system stacking using coax or twinax cable.

? Support for IEEE 802.1D bridging and spanning tree algorithm in an external processor.

? Embedded SmartPath? Processor supports value-added datapath operations.

? Two 32-bit memory interfaces for flexible combinations of SSRAM, SDRAM, and EPROM allows cost optimization of different applications.

? Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types.

APPLICATIONS

? Ethernet Switching System Requiring High Density 10/100 Ports.

? Ethernet Switching Systems Capable of 10, 100, and 1000 Mbit/s Operation When Used with PM3380 and PM3390.
