MPC8321CZQAFDC

Overview

The MPC8321CZQAFDC is a low-power PowerQUICC II Pro integrated communications processor based on the e300c2 core. It features a single 32-bit RISC QUICC Engine, five Unified Communication Controllers (UCCs), and a security engine supporting DES, AES, and SHA-1. The device includes a 32-bit DDR1/DDR2 memory controller operating up to 266 MHz, a 32-bit PCI controller at 66 MHz, and USB 2.0 support. It utilizes a 516-pin PBGA package.

Feature Summary

• Integrates an e300c2 core with dual integer units for efficient parallel processing without a floating-point unit.
• Provides a versatile QUICC Engine block with five UCCs supporting Ethernet, TDM, HDLC, and USB protocols.
• Includes a dedicated security engine for hardware-accelerated cryptographic operations like IPsec and IEEE 802.11i.

Applications

• ADSL SOHO and residential gateways
• Broadband modem/routers
• Industrial control systems

Procurement Notes

Verify that the specific suffix 'C' in MPC8321CZQAFDC corresponds to the required temperature range or packaging variant as defined in the official NXP ordering information. Confirm that the component meets the necessary environmental compliance standards for the intended deployment region before finalizing procurement.

Selection Notes

Select this processor for applications requiring a balance of CPU performance and low power consumption. It is suitable for designs needing integrated networking capabilities via QUICC Engine and secure data handling. Ensure the system design accommodates the 516-pin PBGA package and supports both DDR1 and DDR2 memory interfaces.

Part Context

This component belongs to the MPC8323E family of cost-effective network communication processors. It shares architectural similarities with the MPC8323E but lacks specific high-speed ATM interface support found in other family members. It serves as a solution for small office/home office and industrial networking environments.
