MPC8321EVRAFDC

Overview

The MPC8321EVRAFDC is a PowerQUICC II Pro System-on-Chip microprocessor manufactured by NXP Semiconductors, formerly Freescale. It features a single e300c2 core operating at a maximum clock frequency of 266 MHz with a 32-bit data bus width. The device utilizes a PBGA-516 package and operates within an extended temperature range of -40°C to +105°C. It supports DDR1 and DDR2 SDRAM memory types via a 1V core voltage supply and provides I/O voltages of 1.8V, 2.5V, or 3.3V. Key integrated peripherals include a QUICC Engine, PCI controller, USB 2.0 interface, and a Security Engine (SEC).

Feature Summary

• Integrates a single RISC-based QUICC Engine communication module supporting programmable protocol termination for networking applications.
• Includes a dedicated hardware security engine providing acceleration for encryption algorithms such as DES, AES, and SHA.
• Features an e300c2 processor core optimized for integer operations without a floating-point unit to enhance performance efficiency.

Applications

• Residential gateways
• Small office/home office (SOHO) networks
• VPN routers
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to the end-of-life status. Confirm RoHS compliance details and moisture sensitivity levels prior to assembly. Ensure compatibility with existing PCB footprints and thermal management solutions designed for the PBGA-516 package. Review official errata sheets for any known silicon revisions affecting system stability.

Selection Notes

Select this component for designs requiring high integration of networking protocols and security functions in a compact form factor. Consider the absence of a floating-point unit when evaluating computational requirements for signal processing tasks. Verify that the available I/O voltage options align with the target system's peripheral logic levels and power budget constraints.
