MB91401
2
• For DES-ECB/DES-CBC/3DES-ECB/3DES-CBC mode*
• For MD5/SHA-1/HMAC-MD5/HMAC-SHA-1 mode
• DH group: for 1 (MODP 768 bit) /2 (1024 bit)
For the encryption/authentication macros, a software library is available by contacting the Fujitsu sales repre-
sentative as required.
* : Encryption function (DES/3DES)
Method to encrypt, and to decrypt plaintext in 64 bits with code and decoding key to 56 bits. (3DES is repeated
three times. The key can be set by 168 bits or less.)

Packet filtering function
The internal feature for L3/L4 packet filtering lets specific data pass or halts them based on address (IP/MAC
address) settings. Moreover, the function (multicast address filter function) to receive the data is provided in
case of the multicast address registered besides my address, too.
• IEEE 802.3 compliant 10/100M MAC
• MII interface (for full-duplex/half-duplex)
• SMI interface for PHY device control
Note : The filtering function of layer 3/4 (mount on hardware).
This feature determines whether to pass or discard packets when this layer 3 (network layer) IP addresses
or layer 4 (transport layer) TCP/UDP port numbers match conditions.

Outside interface with telecommunication facility (EXTERNAL INTERFACE)
MB91401 is equipped it with the register for the communication and with mass sending and receiving FIFO that
achieves a large amount of data sending and receiving. Host functions include processing of data stored in a
3 KByte receive buffer and a 1.5 KByte transmit buffer and stopping of data reception. when the buffers become
full.
This enables communication control even during data transmission and reception, thereby improving commu-
nication efficiency while reducing the CPU load.
• 8/16 bit data port
• Equipped with sending and receiving data port control function
• Transfer rate : 133 Mbps (Max)
••••
General Purpose IO (GPIO)
The interruption can be generated in the I/O port in eight bits according to changing the input signal. Moreover,
the I/O setting can be done in each bit.
••••
Memory Interface
It is possible to connect it with an external memory.
••••
USB Function Controller
It can not operate as host USB.
• For USB FUNCTION Rev2.0FS
• Double Buffer Specification
