MPC8321CVRAFDCA

Overview

The MPC8321CVRAFDCA is a 32-bit PowerQUICC II Pro communications processor based on the e300c2 core. It operates at 333 MHz with 16 KB L1 instruction and data caches. The device integrates a QUICC Engine, Security Engine (SEC 2.2), PCI controller, USB 2.0, and DDR1/DDR2 memory controllers. It utilizes a PBGA-516 package and supports I/O voltages of 1.8 V, 2.5 V, and 3.3 V. Operating temperature range is -40°C to +105°C.

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 unified communication controller architecture supporting multiple serial protocols.

Applications

• ADSL SOHO and residential gateways
• Broadband access routers and modem/routers
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm moisture sensitivity level handling during storage and assembly. Validate that the specific ordering suffix matches required voltage and temperature specifications. Ensure supply chain documentation aligns with current manufacturing standards.

Selection Notes

Select this processor for applications requiring integrated networking capabilities without floating-point processing. Consider the absence of UTOPIA support compared to higher-end family members. Evaluate power consumption requirements against the specified typical dissipation values. Ensure software compatibility with existing PowerQUICC designs if migration is planned.
