MPC8321EZQAFDC

Overview

The MPC8321EZQAFDC is a PowerQUICC II Pro integrated communications processor based on the e300c2 core. It features a 32-bit architecture with 16 KB L1 instruction and data caches, dual integer units, and MMUs, but lacks a floating-point unit. The device includes five Unified Communication Controllers (UCCs) supporting Ethernet, HDLC, UART, and BISYNC protocols. Key peripherals include a 32-bit PCI controller, four DMA channels, a security engine (SEC 2.2), and a DDR1/DDR2 memory controller. It operates at frequencies up to 333 MHz.

Feature Summary

• Integrates a QUICC Engine block for programmable protocol termination and network interface support.
• Includes a dedicated security engine providing hardware acceleration for cryptographic algorithms.
• Features a flexible local bus and a 32-bit PCI controller for system interconnectivity.
• Supports DDR1 and DDR2 SDRAM interfaces for high-speed memory access.

Applications

• ADSL SOHO and residential gateways
• Modem/routers
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify component authenticity through official NXP distributors or authorized partners. Confirm the specific suffix matches the required package and temperature grade. Check for RoHS compliance status as indicated in ordering information. Ensure supply chain documentation aligns with current manufacturing standards.

Selection Notes

Select this processor for applications requiring low-power, cost-effective networking solutions. Consider the absence of a floating-point unit when evaluating computational needs. Verify that the UCC protocol support meets specific interface requirements, noting the lack of UTOPIA support compared to other family members.

Part Context

This component belongs to the MPC8323E PowerQUICC II Pro family. It shares architectural similarities with the MPC8323E but excludes the UTOPIA interface found in higher-end variants. The MPC8321 variant focuses on essential communication controllers while maintaining compatibility with previous PowerQUICC software designs.
