MPC8321ECVRAFDC

Overview

The MPC8321ECVRAFDC is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core operating at 266 MHz. It includes a QUICC Engine with five Unified Communication Controllers (UCCs) supporting Ethernet, TDM, and USB 2.0 protocols. The device integrates a 32-bit DDR1/DDR2 memory controller, a PCI 2.2 interface up to 66 MHz, and a Security Engine for hardware acceleration of cryptographic algorithms. It operates within a -40°C to +105°C temperature range.

Feature Summary

• Integrated QUICC Engine with five UCCs for flexible protocol termination including Ethernet, TDM, and HDLC.
• Hardware security engine providing acceleration for DES, 3DES, AES, SHA-1, and MD-5 algorithms.
• Dual integer units in the e300c2 core enabling parallel execution of integer operations without a floating-point unit.
• Support for both DDR1 and DDR2 SDRAM via a single 32-bit interface.

Applications

• ADSL SOHO and residential gateways
• Modem/router networking equipment
• Industrial control systems
• Test and measurement applications

Procurement Notes

Verify the specific suffix 'RA' against official documentation to confirm package type and temperature grade. Confirm end-of-life status as this component family may be obsolete. Ensure design-in compatibility with existing PowerQUICC software stacks due to backward compatibility features.

Selection Notes

Select this processor for cost-effective, low-power networking solutions requiring high integration. It is suitable for designs needing simultaneous support for IP packet processing and ATM networks. Consider the absence of a floating-point unit if complex mathematical operations are required.

Part Context

This part belongs to the MPC8321E series within the PowerQUICC II Pro family. It shares architectural similarities with the MPC8323E but lacks UTOPIA interface support. The e300c2 core is based on the MPC603e architecture, offering enhanced performance over previous generations while maintaining software compatibility.
