PMC-Sierra,Inc. PM3380 Gigabit Ethernet Switch Port Controller FEATURES • Monolithic intelligent Gigabit Ethernet Switch Port Controller. • Integrates an IEEE 802.3z-compatible Gigabit MAC. • May be used alone or in combination with other devices to build 10/100 or Gigabit switches. • Supports the Gigabit EXACT™ Bus Protocol for device interconnect. • May be used alone or in combination with other device to build high density Gigabit switches. • PM3390 EXACT Bus Switch Matrix allows non-blocking expansion up to 16 Gigabit ports. • Layer 2 line rate address lookup capability for all Ethernet port configurations supported. • Store-and-forward switching using output association input buffering for efficient memory use without Head Of Line (HOL) blocking. • Supports up to 8,000 MAC addresses. • Hardware statistics collection supports RMON-I (nine groups), Ethernet MIB, and SNMP agent functions. • All statistics registers and data structures accessible through the CMI. • Supports the implementation of Spanning Tree (IEEE 802.1D) by exchanging BPDU packets on all ports. VLAN • Up to 4094 IEEE 802.1Q VLAN tags with support for 4094 FIDs. • Up to 1022 active VLANs. VALUE ADD • Control and Management Interface provides standard interface for non real-time access to data structures (such as SNMP and RMON applications). • Customer product differentiation is enabled by applications using CMI calls to leverage EXACT system resources. COMPATIBILITY • Interworks with the PM3370 Octal 10/100 Switch Port Controller. • Ingress filtering of packets. • Shared and independent learning. • GARP, GVRP, GMRP packet identification and forwarding to external CPU for processing. • Tag insertion and removal for unicast and multicast packets. PRIORITY • Class of service supported via IEEE 802.1D (formerly 802.1p) with two levels of priority. • Interworks with the PM3390 Eight Port EXACT Bus Switch Matrix. PACKAGING • Provides a standard five signal P1149.1 JTAG test port for boundary scan board test purposes. • Implemented in low power 3.3 V, CMOS technology with 5 V tolerant MII interface. • Available in a 352-pin Ball Grid Array (BGA) package. • 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. BLOCK DIAGRAM EXACT Bus Reference Clock System Clock • 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 and EPROM allow cost optimization of different applications. • Programmable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types.
