Overview

The MPC8321E PowerQUICC®. II Pro is a member of the MPC8323E family of cost-effective network communications processosr that meet the requirements of several small office/home office SOHO, access, IP services and industrial control applications. It provides better CPU performance, additional functionality and faster interfaces than current PowerQUICC™ II processors while addressing important time to market, price, power consumption and board real estate requirements

**Core Complex**

The MPC8321E incorporates a unique configuration of the e300c2 MPC603e-based core. While this version of e300 core does not have a Floating-Point Unit FPU it has been designed to include dual integer units as well as a modified multiply instruction. These architectural enhancements enable more efficient operations to be executed in parallel, resulting in significant performance improvement. The core also includes 16 Kbytes of L1 instruction and data caches and on-chip memory management units MMUs. The MPC8321E also includes a 32-bit PCI controller, four DMA channels, a flexible local bus, and a 32-bit DDR-1/DDR-2 SDRAM memory controller..

**QUICC Engine™ Technology**

A new single-RISC version of the QUICC Engine™ communications engine forms the heart of the networking capability of the MPC8321E. The QUICC Engine® block contains several peripheral controllers and a single 32-bit reduced instruction set computing RISC controller. Unique microcode packages provide support for NAT, Firewall, IPSec, and Advanced Quality of Service QoS. Protocol support is provided by the main workhorses of the device - the unified communication controllers UCCs. Each of the five UCCs can support a variety of communication protocols:

*  Up to 3 10/100 Mbps Ethernet

*  High-level data link control HDLC

*  Up to 4 Time division multiplexing TDM

*  Binary synchronous communications protocol BISYNC

*  UCC can also support USB 2.0 full/low speed

**Hardware Security Engine**

The security engine SEC 2.2 on the MPC8321E allows CPU-intensive cryptographic operations to be off-loaded from the main CPU core. The security-processing accelerator provides hardware acceleration for DES, 3DES, Advanced Encryption Standard AES, Secure Hash Algorithm SHA-1 and MD-5 algorithms.

**System Interface Unit**

The MPC8321E family also includes a 32-bit double data rate DDR-1/DDR/2 memory controller, a 32-bit peripheral component interconnect PCI controller, a 16-bit local bus and four direct memory access DMA channels.

**Typical Applications**

*  Residential gateways

*  SOHO networking

*  VPN routers

*  Access points

*  DSLAM line cards

*  Industrial control

*  Test and measurement equipment
