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.  
• Layer 2 line rate address lookup  
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.
