Octal 10/100 Mbit/s Switch Port-Controller
PM3370
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
TM
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.
MANAGEMENT
System Interface provided in CMI to
support standard SNMP software
packages, or the porting of existing
management software.
Hardware statistics collection supports
RMON-I (9 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.
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.
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 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
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.
