PMC-Sierra,Inc. PM3370 Octal 10/100 Mbit/s Switch Port-Controller 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. • 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. • Ingress filtering of packets. • Shared and independent learning. • GARP, GVRP, GMRP packet identification and forwarding to external CUP for processing. • Tag insertion and removal for unicast and multicast packets. • A MAC bypass mode (ENTRE mode) allows a 800 Mbit/s full duplex access channel into the device with 32-bit FIFO bus. • Allows connection of proprietary ASICs to an EXACT system. • Supports ATM or Packet over SONET applications. • Customer product differentiation is enabled by applications using CMI calls to leverage EXACT resources. COMPATIBILITY • Interworks with the PM3380 Gigabit Switch Port Controller. • Interworks with the PM3390 8-Port EXACT Bus Switch Matrix. PACKAGING PRIORITY • Class of service supported via IEEE 802.1D (formerly 802.1p) with two levels of priority. VALUE ADD • Control and Management Interface provides standard interface for non real-time access to data structures (such as SNMP and RMON applications). • Provides a standard 5-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.
