MPC8321VRADDCA

Overview

The MPC8321VRADDCA is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core operating at 266 MHz. It includes a QUICC Engine with five UCCs, 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, UART, SPI, and I2C. It operates within a -40°C to +105°C temperature range using a PBGA-516 package.

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 DES, 3DES, AES, SHA-1, and MD-5 algorithms.
• 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 flexible 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 due to End-of-Life status. Confirm that the specific ordering suffix matches required environmental and packaging specifications. Ensure compatibility with existing software designs given the backward compatibility claims. Validate power sequencing requirements during integration to avoid excessive current draw.

Selection Notes

Select this processor for cost-effective networking solutions requiring high integration. Consider the absence of a floating-point unit when evaluating computational needs. Verify that the available peripheral count meets system interface requirements. Assess thermal management capabilities for the specified industrial temperature range.

Part Context

This component belongs to the MPC8321E family of low-power PowerQUICC processors. It shares architectural similarities with the MPC8323E but lacks UTOPIA support. The series targets applications demanding efficient data-plane and control-plane processing with reduced board real estate and power consumption.
