Security Processor 252-Pin MAPBGA Tray

The MPC184 security processor is optimized for any system supporting Freescale"s 8xx bus and the 32-bit PCI interface standard. It is designed to off-load computational intensive security functions, such as key generation and exchange, authentication and bulk encryption from processors such as Freescale"s MPC8xx and MPC824x family of integrated host processors, or from any processor through the use of a PCI bridge chip. Typical applications include SOHO/ROBO routers, DSLAMS, Broadband access equipment, e-commerce servers and WAP gateways.
