MPC8321VRAFDC

Overview

The MPC8321VRAFDC is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core with dual integer units and 16 KB L1 instruction/data caches. It includes a QUICC Engine block with five Universal Communication Controllers (UCCs) supporting Ethernet, TDM, HDLC, UART, and BISYNC protocols. The device integrates a 32-bit DDR1/DDR2 memory controller, a 32-bit PCI controller, USB 2.0, and a Security Engine (SEC 2.2). Operating at up to 266 MHz, it supports 1.0 V core voltage and 1.8 V/2.5 V DDR I/O.

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 a unified communication controller architecture supporting diverse serial interfaces including Ethernet, TDM, and ATM.
• Provides backward software compatibility with previous-generation PowerQUICC processor designs.

Applications

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

Procurement Notes

Verify the specific suffix 'VRAFDC' against official NXP documentation to confirm package type, temperature range, and lead-free status. Confirm current lifecycle status as this component family may be subject to end-of-life notices. Ensure design-in compliance with moisture sensitivity levels and power sequencing requirements specified in the hardware specifications.

Selection Notes

Select this processor for applications requiring high integration of communication protocols and security features within a low-power footprint. Consider the absence of a floating-point unit when evaluating computational requirements. Verify that the required peripheral count, specifically UTOPIA support if needed, aligns with the MPC8321 variant limitations compared to the MPC8323E.

Part Context

This component belongs to the MPC8321 series within the PowerQUICC II Pro family. It shares architectural similarities with the MPC8323E but lacks specific features like UTOPIA support found in higher-end variants. The MPC8321 is designed to offer a cost-effective solution for networking applications while maintaining compatibility with existing PowerPC software ecosystems.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers. Cross-reference with MPC8321E or MPC8323E variants only if feature sets such as UTOPIA support are not required or are explicitly supported by the alternative.
