MPC8321ECVRAFDCA

Overview

The MPC8321ECVRAFDCA is a PowerQUICC II Pro integrated communications processor built on the e300c2 core. It features a single 32-bit RISC controller, five unified communication controllers (UCCs), and a security engine supporting DES, 3DES, AES, SHA-1, and MD-5 algorithms. The device includes a 32-bit DDR1/DDR2 memory controller operating up to 266 MHz, a 32-bit PCI interface up to 66 MHz, USB 2.0, and four TDM ports. It operates within a junction temperature range of 0 to 105 °C.

Feature Summary

• Integrates QUICC Engine technology with five UCCs for flexible protocol termination including Ethernet, HDLC, and TDM.
• Includes a dedicated security engine providing hardware acceleration for cryptographic operations such as IPSec and IEEE 802.11i.
• Supports dual DDR1 and DDR2 SDRAM interfaces via a 32-bit controller with on-the-fly power management capabilities.

Applications

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

Procurement Notes

Verify component authenticity through authorized NXP distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the PBGA-516 specification before integration. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements during storage and soldering processes.

Selection Notes

Select this processor for applications requiring high-performance packet processing with low power consumption. It is suitable for designs needing backward compatibility with previous PowerQUICC software architectures. Consider its specific I/O voltage requirements and thermal characteristics when designing the system board layout.

Part Context

This component belongs to the MPC8323E family of PowerQUICC II Pro processors. It shares architectural similarities with the MPC8323E but lacks support for the UTOPIA interface found in higher-end models. The e300c2 core provides enhanced integer performance without a floating-point unit, optimizing cost and power efficiency for networking tasks.
