MPC8321EVRAFDC

Overview

The MPC8321EVRAFDC is a PowerQUICC II Pro processor featuring an e300c2 core with dual integer units and 16 KB L1 caches. It integrates five Unified Communication Controllers (UCCs) supporting Ethernet, TDM, HDLC, and USB 2.0. The device includes a 32-bit DDR1/DDR2 memory controller operating up to 266 MHz, a 32-bit PCI controller at 66 MHz, and a SEC 2.2 security engine for hardware-accelerated encryption algorithms.

Feature Summary

• Integrated QUICC Engine technology provides programmable protocol termination for evolving network standards.
• SEC 2.2 security engine offloads CPU-intensive cryptographic operations including DES, AES, and SHA-1.
• Dual integer units in the e300c2 core enable parallel execution of efficient operations.

Applications

• ADSL SOHO and residential gateways
• Industrial control systems
• Test and measurement equipment

Procurement Notes

Verify the specific suffix EVRAFDC against official NXP documentation to confirm package type, temperature range, and revision level. Ensure compatibility with existing system designs regarding voltage requirements and pin configurations before procurement.

Selection Notes

Select this component for applications requiring high integration of communication protocols and security features. The absence of a floating-point unit makes it suitable for integer-heavy networking tasks. Evaluate power consumption profiles against system thermal constraints.

Part Context

This part belongs to the MPC8323E PowerQUICC II Pro family. It shares architectural similarities with other members like the MPC8323E but lacks specific interfaces such as UTOPIA found in higher-end variants within the same series.

Replacement Considerations

Consult official substitution lists for compatible processors within the PowerQUICC II Pro family. Verify software compatibility and peripheral availability when considering alternative models.
