MPC8321ZQAFDC Overview

The MPC8321 PowerQUICC® II Pro is part of the MPC8323E family of cost-effective network communication processors that meet the requirements of several small office/home office (SOHO), broadband access, routers and industrial control applications. It provides better CPU performance, additional functionality and faster interfaces than current PowerQUICC processors while addressing important time to market, price, power consumption and board real estate requirements.

Core Complex
The MPC8321 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 MPC8321 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 MPC8321. 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 (NAPT), 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 three 10/100 Mbps Ethernet
  • High-level data link control (HDLC)
  • Up to four time division multiplexing (TDM)
  • Binary synchronous communications protocol (BISYNC)
  • UCC can also support USB 2.0 (full/low-speed)

System Interface Unit
The MPC8321 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.

Features

  • e300 core with dual integer units enables more efficient operations to be conducted in parallel, resulting in significant performance improvement
  • The single-RISC QUICC Engine® communications block offers a future-proof solution for next-generation designs by supporting programmable protocol termination and network interface termination to meet evolving protocol standards
  • DDR-1/DDR-2 memory controller—one 32-bit interface operating at up to 266 MHz supporting both DDR-1 and DDR-2
  • Peripheral interfaces such as 32-bit, 66 MHz PCI, 16-bit, 66 MHz local bus interface and USB 2.0 (full/low-speed)
  • High degree of software compatibility with previous-generation PowerQUICC® processor-based designs for backward compatibility and easier software migration
  • This product is included in NXP®.s product longevity program, with assured supply for a minimum of 10 years after launch
