FEATURES
- Monolithic intelligent octal 10/100 Ethernet Switch Port Controller.
- I n t egrates 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.
- M ay 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.
- L ayer 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.
- Pro grammable packet pattern matchers for identification of ARP, RARP, ICMP, and other protocol or packet types. MANAGEMENT
- S ystem Interface provided in CMI to support standard SNMP software packa ges, or the porting of existing mana gement software.
- Hardware statistics collection supports RMON-I (9 groups), Ethernet MIB, and SNMP a gent 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.
- I ngress filtering of packets.
- Shared and independent learning.
- GARP, GVRP, GMRP packet identification and forwarding to external CUP for processing.
- T ag 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. VALUE ADD
- Control and Management Interface provides standard interface for non real-time access to data structures (such as SNMP and RMON applications).
- A M A C 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
- 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.
