MPC8321ECZQADDC

Overview

The MPC8321ECZQADDC is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core operating at 266 MHz. It includes a QUICC Engine with five unified communication controllers, a security engine (SEC 2.2), and a 32-bit DDR1/DDR2 memory controller. The device supports PCI 2.2 up to 66 MHz, USB 2.0, Ethernet, TDM, and serial interfaces within a PBGA-516 package.

Feature Summary

• Integrates a single RISC QUICC Engine block for programmable protocol termination and network interface support.
• Includes a dedicated security engine providing hardware acceleration for DES, 3DES, AES, SHA-1, and MD-5 algorithms.
• Features dual integer units within the e300c2 core to enable parallel execution of operations without a floating-point unit.

Applications

• Residential gateways
• SOHO network routers
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm specific ordering suffixes against official datasheets as they define temperature ranges and packaging variations. Request current production status documentation from suppliers to ensure availability before finalizing design-in decisions.

Selection Notes

Select this processor for applications requiring high integration of networking protocols and hardware security acceleration. Ensure system designs accommodate the specific voltage requirements for the core and I/O domains. Verify that the absence of a floating-point unit aligns with the computational needs of the target software environment.

Part Context

This component belongs to the MPC8323E family of cost-effective network communication processors. It shares architectural similarities with the MPC8323E but lacks certain ATM-specific features like UTOPIA support found in higher-end siblings. It represents a generation of PowerQUICC processors designed for converged IP and ATM packet processing.

Replacement Considerations

Consult official NXP documentation for direct pin-compatible or functional substitutes within the MPC83xx series. Verify backward compatibility of software drivers when migrating between different revisions or sibling models in the PowerQUICC family.
