MPC8323ECVRADDCA

MPU PowerQUICC II Pro MPC83xx Processor RISC 32Bit 90nm 266MHz 1.8V/2.5V/3.3V 516Pin TEBGA Tray

Overview

The MPC8323E PowerQUICC® II Pro family includes the MPC8323E, MPC8323, MPC8321E and MPC8321. This cost-effective communications processor family meets the requirements of several small office/home office SOHO, access, IP service 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 MPC8323E 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 KB of L1 instruction and data caches and on-chip memory management units MMUs. The MPC8323E 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-reduced instruction set computing RISC version of the QUICC Engine communications engine forms the heart of the networking capability of the MPC8323E. The QUICC Engine block contains several peripheral controllers and a single 32-bit RISC controller. Unique microcode packages provide support for network address port translation 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:

* 10/100 Mbps Ethernet

* Asynchronous transfer mode ATM support up to OC-3 speeds

* Serial ATM

* Multi-physical layer PHY ATM

* High-level data link control HDLC

* Time division multiplexing TDM

* Binary synchronous communications protocol BISYNC

* UCC can also support USB 2.0 full/low-speed.

In addition, the QUICC Engine can also support a universal test and operations PHY interface for ATM UTOPIA level 2 for up to 31 multi-PHY.

**Hardware Security Engine**

The security engine SEC 2.2 on the MPC8323E and 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 MPC8323E 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
