• USB 2.0 (full/high speed) support
• Power management controller for low-power consumption
• High degree of software compatibility with previous-generation PowerQUICC processor-based
designs for backward compatibility and easier software migration
• Optional security engine provides acceleration for control and data plane security protocols
The optional security engine (SEC 3.0) is noted with the extension “E” at the end. It allows CPU-intensive
cryptographic operations to be offloaded from the main CPU core. The security-processing accelerator
provides hardware acceleration for the DES, 3DES, AES, SHA-1, and MD-5 algorithms.

The eTSECs include the following features:
• Two enhanced Ethernet interfaces can be used for RGMII/MII/RMII/RTBI/SGMII

Integrated Programmable Interrupt Controller (IPIC)
The integrated programmable interrupt controller (IPIC) implements the necessary functions to provide a
flexible solution for general-purpose interrupt control. The IPIC programming model is compatible with
the MPC8260 interrupt controller, and it supports 8 external and 34 internal discrete interrupt sources.
Interrupts can also be redirected to an external interrupt controller.

clocks, A/D converters, and ISDN devices.
The SPI is a full-duplex, synchronous, character-oriented channel that supports a four-wire interface
(receive, transmit, clock, and slave select). The SPI block consists of transmitter and receiver sections, an
independent baud-rate generator, and a control unit.

Overview
There are two I
2
C controllers. These synchronous, multi-master buses can be connected to additional
devices for expansion and system development.
The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550
programming models. 16-byte FIFOs are supported for both the transmitter and the receiver.
The main component of the enhanced local bus controller (eLBC) is its memory controller, which provides
a seamless interface to many types of memory devices and peripherals. The memory controller is
responsible for controlling eight memory banks shared by a NAND Flash control machine (FCM), a
general-purpose chip-select machine (GPCM), and up to three user-programmable machines (UPMs). As
such, it supports a minimal glue logic interface to SRAM, EPROM, NOR Flash EPROM, NAND Flash,
EPROM, burstable RAM, regular DRAM devices, extended data output DRAM devices, and other
peripherals. The eLBC external address latch enable (LALE) signal allows multiplexing of addresses with
data signals to reduce the device pin count.
The enhanced local bus controller also includes a number of data checking and protection features, such
as data parity generation and checking, write protection, and a bus monitor to ensure that each bus cycle
is terminated within a user-specified period. The local bus can operate at up to 133 MHz.
The system timers include the following features: periodic interrupt timer, real time clock, software
watchdog timer, and two general-purpose timer blocks.
1.8
Security Engine
The optional security engine is optimized to handle all the algorithms associated with IPSec,
IEEE 802.11i, and iSCSI. The security engine contains one crypto-channel, a controller, and a set of crypto
execution units (EUs). The execution units are:
• Data encryption standard execution unit (DEU), supporting DES and 3DES
• Advanced encryption standard unit (AESU), supporting AES
• Message digest execution unit (MDEU), supporting MD5, SHA1, SHA-256, and HMAC with any
algorithm
• One crypto-channel supporting multi-command descriptor chains
1.9
PCI Controller
The PCI controller includes the following features:
•
PCI Specification Revision 2.3
