MPC8321EVRADDCA

Overview

The MPC8321EVRADDCA is a PowerQUICC II Pro integrated communications processor built on the e300c2 core. It features a 266 MHz clock speed, 16 KB L1 instruction and data caches, and dual integer units. The device includes a QUICC Engine with five unified communication controllers (UCCs) supporting Ethernet, ATM, HDLC, UART, and BISYNC protocols. It integrates a 32-bit DDR1/DDR2 memory controller, PCI 2.2 interface up to 66 MHz, USB 2.0, and SEC 2.2 security engine for cryptographic acceleration. Operating voltage is 1.0 V core with 1.8/2.5/3.3 V I/O options.

Feature Summary

• Integrates a QUICC Engine block with five UCCs for flexible protocol termination including Ethernet, ATM, and HDLC.
• Includes SEC 2.2 security engine providing hardware acceleration for DES, 3DES, AES, SHA-1, and MD-5 algorithms.
• Supports both DDR1 and DDR2 SDRAM via a single 32-bit memory controller interface.
• Features a 32-bit PCI controller compatible with Specification Revision 2.3 operating up to 66 MHz.

Applications

• ADSL SOHO and residential gateways
• Modem/router networking equipment
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify component authenticity through authorized NXP distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Review the latest errata sheets for known silicon revisions. Ensure supply chain stability as this model may be subject to end-of-life restrictions. Validate package integrity upon receipt to prevent handling damage.

Selection Notes

Select this processor for designs requiring high integration of communication protocols and security functions. The e300c2 core provides efficient processing without floating-point overhead. Consider the specific I/O voltage requirements for DDR and system interfaces. Evaluate software compatibility with existing PowerQUICC codebases for migration ease. Assess thermal management needs based on estimated power dissipation profiles.

Part Context

This component belongs to the MPC8321/MPC8321E family within the broader MPC8323E PowerQUICC II Pro series. It shares architectural similarities with the MPC8323E but lacks the UTOPIA interface support found in higher-end variants. The family targets cost-effective, highly integrated solutions for networking and industrial applications requiring robust protocol handling.

Replacement Considerations

Consult official NXP documentation for current lifecycle status. Verify if newer Power Architecture or Arm-based families are recommended replacements for new designs. Check pin-to-pin compatibility if substituting within the same package type.
