FUJITSU SEMICONDUCTORDATA SHEET32-Bit Proprietary MicrocontrollerLSI Network Security SystemMB91401nnnn DESCRIPTIONThe MB91401 is a network security LSI incorporating a Fujitsu’s 32-bit, FR-family RISC microcontroller with 10/100Base-T MAC Controller, encryption function and authentication function. The LSI contains an encryptionauthentication hardware accelerator that boosts the LSI’s performance for encryption and authentication commu-nication (IKE/IPsec/SSL) to be demanded further.The MAC controller has a packet filtering function that reduces the load on the CPU for an increasing amount ofpacket processing. In addition, the board has the External interface for high-speed data communication withvarious external hosts, USB ports as general-purpose interfaces, and various card interfaces.nnnn FEATURES•••• Encryption and authentication processing by hardware accelerator functionThe LSI performs processing five times faster than by the conventional combination of encryption/authenticationhardware macros and software or about 400 times faster than by software only. In addition, CPU processing loadfactor to be involved in the encryption and the authentication processing can be decreased to 1/5 or less.Also, the LSI uses the embedded accelerator to execute that public-key encryption algorithm about 100 timesfaster than by software processing, which generally puts an extremely heavy load microcontrollers.(Continued)nnnn PACKAGE244-pin plastic FBGA(BGA-240P-M01) |
