PMC-Sierra,Inc.

Preliminary

8-Port 10 Mbit/s Switch

• Store-and-forward operation with full

error checking and filtering.

• Low-latency operation in both unicast

and broadcast modes.

• Filtering and switching at wire rates (up

to 148,8000 packets per second),

supporting a mix of Ethernet and

IEEE 802.3 protocols.

• Performs all address learning, address

table management, and aging

functions for up to 32,768 MAC

addresses (limited by external

memory) with an address learning rate

of up to 10,000 addresses per second.

• Maximum broadcast/multicast rate of

14,880 packets per second per port

with configurable broadcast storm rate

limiting.

• Backpressure flow control with

configurable per-port buffer thresholds

and limits.

• Expandable to 64 ports without loss in

throughput using multiple PM3350

devices via an on-chip 1 Gbit/s

expansion port.

FEATURES

• Single-chip, 8-port, 10BaseT Ethernet

switch device for low-cost unmanaged

and managed networks.

• On-chip SmartPath 50 MHz RISC

CPU core, multi-channel DMA

controller, MAC-layer interface logic,

FIFOs, PCI-based expansion port, and

a flexible memory controller.

• CPU supports background applications

running on local OS (e.g., SNMP), and

real-time data-oriented applications

(e.g., packet forwarding and filtering

decisions).

• Concurrently switches packets

between eight independent, half-

duplex ports at the full Ethernet rate of

10 Mbit/s.

• Fully compatible with the PM3351,

1-port 10/100 Mbit/s switch device;

may be used to create a compact and

inexpensive mixed 10/100 Mbit/s

switching hub.

• Expansion port supports a peak

system bandwidth of 1 Gbit/s, and is

compatible with industry-standard PCI

bus (version 2.1).

• Interfaces directly to industry-standard

10BaseT Ethernet Medium Access

Unit devices (LXT944 or similar) with

no glue logic.

• Configuration, management, MIB

statistics, and diagnostics available

in-band (via on-chip SNMP agent with

integral TCP/UDP/IP stack).

• Maintains and collects per-port and

per-host statistics at wire rates.

• Fully static CMOS operation at 50 MHz

clock rates.

• Implemented with a 3.3 V core and a

5 V-compatible I/O.

• Available in a 256-pin Ball Grid Array

(BGA) package.
