Preliminary

PM3371

Octal 10/100 Mb/s Switch Port-Controller with Standard Features

• Two 32-bit memory interfaces for

flexible combinations of SSRAM,

SDRAM, and EPROM allows cost

optimization of different applications.

• All statistics registers and data

structures accessible through the CMI.

FEATURES

• Monolithic, intelligent, low-cost octal

10/100 Mb/s Ethernet Switch

Port-Controller.

• Supports the implementation of

Spanning Tree (IEEE 802.1D) by

exchanging BPDU packets on all ports.

COMPATIBILITY

• Integrates eight 10/100 MACs that

connect to physical layer devices over

standard IEEE 802.3u MIIs.

PACKAGING

• Interworks with the following EXACT

Chipset devices:

• Provides a standard 5-signal P1149.1

JTAG test port for boundary scan

board test purposes.

• Supports the Gigabit EXACT Bus

Protocol for device interconnect.

PM3370 Octal 10/100 Switch

Port-Controller with Advanced

Features.

• May be used alone or in combination

with other devices to build high density

10/100 switches.

• Implemented in low power 3.3 V,

CMOS technology with 5 V tolerant MII

interface.

PM3380 Gigabit Switch Port-Controller

with Advanced Features.

• Supports non-blocking system

• Available in a 352-pin Ball Grid Array

(BGA) package.

PM3390 8-Port EXACT Bus Switch

Matrix.

configurations up to 128 10/100

ports.

PM3391 6-Port EXACT Bus Switch

Matrix.

capability for all Ethernet port

configurations supported.

APPLICATIONS

• Low Cost Layer 2 Ethernet Switching

System Requiring High Density 10/100

Ports

VALUE ADD

• EXACT Bridge appnote for direct

high-speed external CPU access to the

EXACT Bus.

• Store-and-forward switching using

output associated input buffering for

efficient memory use without Head Of

Line (HOL) blocking.

• Low Cost Ethernet Switching Systems

Capable of 10/100 and 1000 Mb/s

Operation When Used with the

PM3380 Gigabit Switch

MANAGEMENT

• Embedded SmartPath Processor

supports value-added datapath

operations.

• System Interface provided in CMI to

support standard SNMP software

packages, or the porting of existing

management software.

Port-Controller.

• Supports up to 16k MAC addresses.

• Support for IEEE 802.1d bridging and

spanning tree algorithm in an external

processor.

• Hardware statistics collection supports

RMON-1(9 groups), Ethernet MIB, and

SNMP agent functions.
