BCM3310 is a versatile communications processor

and peripheral device, that can be used in a variety of

applications in networking and communications. The

BCM3310 is designed to support applications having

high-performance data transfer requirements such as

Cable Modems, Ethernet Small Office/Home Office

(SOHO) and xDSL applications.

Provides a fully integrated device that integrates the

microprocessor and peripherals functions of a cable

modem into a single device complementing the

BCM3300 DOCSIS-compliant PHY/MAC integrated

circuit by:

•

Reducing overall system cost

•

Simplifying system, board and software design

Reducing power consumption

BCM3310 provides:

•

High-performance MIPS R3000 CPU

•

Built-in seamless interface with the BCM3300

eliminating discrete interface components from the

system design

•

Complete Static Design, 0-80 MHz Operation

10/100 Ethernet MAC with MII Interface

32-bit/33 MHz Master-mode DMA PCI Interface

Universal Serial Bus (USB) Device Interface

80 MHz (85 DMIPS) R3000 CPU with 4K 2-way set

associative I-cache and 1K 2-way set associative

writeback D-cache

IPSEC Interface including DES, Triple-DES, CBC,

MD5, and SHA Algorithm Support

Full IPv6 IP Security (IPSec) module to support

advanced applications such as Virtual Private

Networking (VPN)

TDM Interface capable of supporting up to four voice

channels

•

SDRAM Interface

•

Fully USB 1.0 compliant interface for simple plug and

play external cable modem implementations

•

External Bus Interface (with 8 programmable chip

selects)

PCI NDIS 5.0 miniport driver to accelerate software

development

GPIO Interface

•

3.3V Operation

•

316-pin BGA Package
