Data Sheet
Stream Cipher
• Secure Real-Time Protocol (sRTP) features
– Packet transforms
– ROC removal and TAG insertion
– Variable bypass offset of header length per packet
• Media Access Control Security (MACSec) features
– Cipher suite GCM-AES-128
– Header insertion and removal
– Integrity and confidentiality with MSDU
• SGT L2 supported features:
– GCM-AES with 128-bit key.
– Integrity only and with confidentiality of MSDU
• ICV generation and validation SGT L3 supported features
– AES-GCM, AES-GMAC with 128, 192 and 256 bit key.
• IPsec/SSL security acceleration engine
• DES, 3DES, AES, ARC-4, AES-GCM, and GMAC-AES encryption/decryption
• MD-5, SHA-1, and SHA-256 hashing
• Public key acceleration for RSA, DSA and Diffie-Hellman
• Combined encryption-hash and hash-decryption with the AES-CCM algorithm.
• True or pseudo random number generators
– Non-deterministic true random numbers
– Pseudo random numbers with lengths of 8B or 16B
– ANSI X9.17 Annex C compliant using a DES algorithm
• Interrupt controller
– Fifteen programmable, maskable interrupts
– Initiate commands via an input interrupt
– Sixteen programmable interrupts indicating completion of certain operations
– All interrupts mapped to one level- or edge-sensitive programmable interrupt output
• DMA controller
– Autonomous, 4-channel
– 1024-words (32 bits/word) per DMA transfer
– Scatter/gather capability with byte aligned addressing
– Byte reverse capability on SA and descriptors
UART
The Universal Asynchronous Receiver/Transmitter (UART) interface provides four configurations:
• One 8-signal port
• Two 4-signal ports.
• Two 2-signal ports
• One 4-signal port and one 2-signal port
The UART performs serial-to-parallel conversion on data received from a peripheral device or a modem, and
parallel-to-serial conversion on data received from the processor.
Features include:
• Compatible with the16750
• All six software modem control functions (CTS, RTS, DSR, DTR, RI, DCD) on UART0
• Programmable auto flow (data flow controlled by RTS and CTS signals)
• Characters can be 5, 6, 7, or 8 bits
• Programmable start, stop, parity bit insertion
• Sixty-four byte FIFOs for buffering Tx and Rx data
• LIN sub-bus specification compliant - line break generation/detection and false start bit detection
• Programmable internal/external loopback capabilities
• Low Power and Sleep mode
