Features  
— Advanced encryption standard unit (AESU)  
– Implements the Rinjdael symmetric key cipher  
– ECB, CBC, and counter modes  
– 128-, 192-, and 256- bit key lengths  
— Message digest execution unit (MDEU)  
– SHA with 160- or 256-bit message digest  
– MD5 with 128-bit message digest  
– HMAC with either algorithm  
— Crypto-channel supporting multi-command descriptor chains  
— Integrated controller managing internal resources and bus mastering  
— Buffer size of 256 bytes for the DEU, AESU, and MDEU, with flow control for large data sizes  
Interrupts  
— Six external interrupt request (IRQ) lines  
— 12 port pins with interrupt capability  
— 23 internal interrupt sources  
— Programmable priority between SCCs  
— Programmable highest priority request  
Communications processor module (CPM)  
— RISC controller  
— Communication-specific commands (for example, GRACEFUL STOP TRANSMIT, ENTER HUNT MODE, and  
RESTART TRANSMIT)  
— Supports continuous mode transmission and reception on all serial channels  
— 8-Kbytes of dual-port RAM  
— Several serial DMA (SDMA) channels to support the CPM  
— Three parallel I/O registers with open-drain capability  
On-chip 16 × 16 multiply accumulate controller (MAC)  
— One operation per clock (two-clock latency, one-clock blockage)  
— MAC operates concurrently with other instructions  
— FIR loop—Four clocks per four multiplies  
Four baud rate generators  
— Independent (can be connected to any SCC or SMC)  
— Allow changes during operation  
— Autobaud support option  
Up to three serial communication controllers (SCCs) supporting the following protocols:  
— Serial ATM capability on SCCs  
— Optional UTOPIA port on SCC4  
— Ethernet/IEEE 802.3 optional on the SCC(s) supporting full 10-Mbps operation  
— HDLC/SDLC  
— HDLC bus (implements an HDLC-based local area network (LAN))  
— Asynchronous HDLC to support point-to-point protocol (PPP)
