Freescale Semiconductor

Overview

1.3

Security Engine

The security engine is optimized to handle all the algorithms associated with IPSec, IEEE 802.11i®

standard, 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

1.4

DDR Memory Controller

The MPC8323E DDR1/DDR2 memory controller includes the following features:

•

Single 32-bit interface supporting both DDR1 and DDR2 SDRAM

•

Support for up to 266-MHz data rate

•

Support for two x16 devices

•

Support for up to 16 simultaneous open pages

•

Supports auto refresh

•

On-the-fly power management using CKE

•

1.8-/2.5-V SSTL2 compatible I/O

•

Support for 1 chip select only

•

FCRAM, ECC, hardware/software calibration, bit deskew, QIN stage, or atomic logic are not

supported.

1.5

PCI Controller

The MPC8323E PCI controller includes the following features:

•

PCI Specification Revision 2.3 compatible

•

Single 32-bit data PCI interface operates up to 66 MHz

•

PCI 3.3-V compatible (not 5-V compatible)

•

Support for host and agent modes

•

On-chip arbitration, supporting three external masters on PCI

•

Selectable hardware-enforced coherency

1.6

Programmable Interrupt Controller (PIC)

The programmable interrupt controller (PIC) implements the necessary functions to provide a flexible

solution for general-purpose interrupt control. The PIC programming model is compatible with the

MPC8260 interrupt controller, and it supports 8 external and 35 internal discrete interrupt sources.

Interrupts can also be redirected to an external interrupt controller.
