MPC8321CVRAFDC

Overview

The MPC8321CVRAFDC is a low-power PowerQUICC II Pro processor featuring an e300c2 core with dual integer units and 16 KB L1 caches. It integrates a QUICC Engine with five Unified Communication Controllers (UCCs) supporting Ethernet, TDM, HDLC, BISYNC, and USB 2.0. The device includes a 32-bit DDR1/DDR2 memory controller, a 32-bit PCI controller, and a Security Engine (SEC 2.2). It lacks UTOPIA support and does not contain a floating-point unit.

Feature Summary

• Integrates a single RISC QUICC Engine block for programmable protocol termination and network interface management.
• 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 multiple serial protocols including Ethernet, TDM, and USB.

Applications

• ADSL SOHO gateways
• Residential gateways
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors or NXP directly. Confirm the specific suffix 'VRAFDCA' matches the required package and temperature grade. Check for End of Life status and ensure replacement strategies are in place if necessary.

Selection Notes

Select this model for applications requiring integrated communications processing without ATM UTOPIA support. Ensure design compatibility with the e300c2 core architecture and verify that the absence of a floating-point unit meets computational requirements.

Part Context

This part belongs to the PowerQUICC II Pro family, designed as a cost-effective solution for networking applications. It extends previous generations by offering higher CPU performance and faster interfaces while maintaining backward software compatibility with earlier PowerQUICC designs.

Replacement Considerations

MPC8321E variants may offer similar functionality but require verification of specific feature sets such as UTOPIA support and clock speeds against the MPC8321CVRAFDC specifications.
