MPC8321EVRADDC

Overview

The MPC8321EVRADDC is a PowerQUICC II Pro microprocessor featuring an e300c2 core operating at 266 MHz. It integrates a QUICC Engine with five Unified Communication Controllers, a Security Engine (SEC 2.2), and a 32-bit DDR1/DDR2 memory controller. The device supports PCI 2.2 up to 66 MHz, USB 2.0, and multiple serial interfaces including Ethernet, TDM, HDLC, and UART. It utilizes a PBGA-516 package and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a single RISC QUICC Engine block for programmable protocol termination and network interface support.
• Includes a dedicated security engine providing hardware acceleration for cryptographic algorithms such as DES, AES, and SHA-1.
• Features dual integer units within the e300c2 core to enable parallel execution of operations without a floating-point unit.
• Supports convergence of IP packet networks and ATM networks through versatile communication controllers.

Applications

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

Procurement Notes

Verify component authenticity against official NXP documentation prior to integration. Confirm that the specific ordering suffix matches the required voltage and temperature specifications. Ensure design compatibility with the PowerQUICC II Pro architecture. Check for any published errata relevant to the revision. Validate power sequencing requirements during system initialization.

Selection Notes

Select this processor for designs requiring high software compatibility with previous-generation PowerQUICC solutions. Consider its low-power characteristics and cost-effectiveness for embedded networking tasks. Evaluate the integrated QUICC Engine capabilities for handling complex communication protocols. Assess the need for hardware security acceleration features in the target application environment.
