MPC8321VRAFDCA

Overview

The MPC8321VRAFDCA is a low-power PowerQUICC II Pro processor in a BGA516 package. It features an e300c2 core with dual integer units and 16 KB L1 caches, lacking an FPU. The device integrates a QUICC Engine with five UCCs supporting Ethernet, TDM, HDLC, BISYNC, and USB 2.0. It includes a SEC 2.2 security engine for hardware acceleration of DES, AES, and SHA-1. Memory interfaces include a 32-bit DDR1/DDR2 controller up to 266 MHz and a 32-bit PCI controller operating at 66 MHz.

Feature Summary

• Integrated QUICC Engine with five unified communication controllers for flexible protocol termination
• Hardware security engine providing acceleration for cryptographic algorithms
• Dual integer unit architecture within the e300c2 core for efficient parallel processing
• Support for both DDR1 and DDR2 SDRAM memory standards

Applications

• ADSL SOHO and residential gateways
• Industrial control systems
• Test and measurement equipment
• IP services and modem/routers

Procurement Notes

Verify component status as End of Life before procurement planning. Confirm lead-free soldering compatibility and moisture sensitivity level 3 requirements during assembly. Ensure voltage tracking between core and I/O supplies to prevent contention. Review material declarations for RoHS and REACH SVHC compliance prior to integration.

Selection Notes

Select this model for applications requiring high software compatibility with previous PowerQUICC designs. Choose when a cost-effective single-chip solution for ATM or IP packet processing is needed. Consider the absence of an FPU and UTOPIA support specific to this variant compared to higher-end family members.

Part Context

This component belongs to the MPC8323E PowerQUICC II Pro Integrated Communications Processor Family. It shares architectural similarities with the MPC8323E but lacks specific features like UTOPIA support found in other family members. The part is designed to address networking requirements while minimizing power consumption and board space.
