PRODUCTION SPECIFICATION

■ BCM5802

Single-Chip Security Processor

G E N E R A L D E S C R I P T I O N

F E A T U R E S

The BCM5802 Security Processor provides industry-

standard IETF IPsec encryption and authentication

acceleration as well as IKE/SSL/TLS key setup

acceleration. Engine throughput is over 150 Mbps with

3DES strong encryption and MD5/SHA1 authentication

enabled. Sustained in-system performance with all

features enabled ranges up to 100 Mbps for crypto/

authentication acceleration and 30 1024-bit Diffie-Hellman

(180-bit exponent) key setups per second. The BCM5802

is ideal for cost-sensitive devices, including cable modem

access systems, xDSL access systems, T1/T3 line

security, and 10/100 Mbps ethernet interfaces.

•

High-performance, low-cost security processor

integrating full IPsec acceleration

Supports DES, 3DES, HMAC-SHA1 and HMAC-MD5

100 Mbps IPsec (3DES, SHA1) in-system

performance, with new Security Association (SA) per

packet

Unlimited SA support via system memory

Extensive hardware support for IKE/SSL/TLS key

setup acceleration

Public key acceleration unit supports over 30

Diffie-Hellman key exchanges per second

Compatible with SSH IPsec and IKE software

True hardware random number generator

Supports multi-packet processing and pre-fetch of

packet data and context

Aggressive pre-fetch DMA allows multi-packet, multi-

threaded, DMA processing with single PCI writes

Full performance maintained independent of any

reasonable PCI latency

PCI 2.2 interface, 32-bit, 33 MHz

Low-power 3.3V design in 0.35µ CMOS technology

144-pin DQFP package

•

The BCM5802 includes a built-in PCI 2.2 compliant

interface for easy hardware interfacing. It requires zero

external support components, enabling tremendous

system cost savings, and it features a streamlined high-

performance programming model for easy software

integration.
