This technical summary provides an overview of the MPC185 Security Processor, including

a brief development history, target applications, key features, typical system architecture,

device architectural overview, and a performance summary.

1 Development History

The MPC185 belongs to the Smart Networks platform’s S1 family of security processors

developed for the commercial networking market. This product family is derived from

security technologies Motorola has developed over the last 30 years, primarily for government

applications. The fifth-generation execution units (EU) have been proven in Motorola

semi-custom ICs and in the MPC180 and MPC190, two products in Motorola’s security

processor line.

2 Typical Applications

The MPC185 is suited for applications such as the following:

•

Edge routers

•

Broadband access equipment

•

eCommerce servers

•

Wireless base stations

•

WAP gateways

3 Features

The MPC185 is a flexible and powerful addition to any networking or computing system using

the Motorola PowerQUICC II line of integrated communications processors, or any system

supporting the 60x bus protocol. The MPC185 is designed to offload computationally

intensive security functions, such as key generation and exchange, authentication, and bulk

encryption from the host processor with PowerPC architecture.

The MPC185 is optimized to process all the algorithms associated with IPSec, IKE,

WTLS/WAP, SSL/TLS and 3GPP. In addition, the Motorola family of security co-processors
