MPC8321EVRADDCA

Overview

The MPC8321EVRADDCA is a 32-bit PowerQUICC II Pro System on Chip (SoC) based on the e300c2 core, operating at a maximum frequency of 266 MHz. It integrates a QUICC Engine for network processing and a Security Engine (SEC 2.2) for hardware acceleration. The device supports DDR1/DDR2 SDRAM via a 32-bit controller and includes a 32-bit PCI interface. Key peripherals include USB 2.0, Ethernet, I2C, SPI, UART, GPIO, and four timers. It operates within a temperature range of -40°C to +105°C using a PBGA-516 package.

Feature Summary

• Integrates an e300c2 core with dual integer units for efficient parallel operation without a floating-point unit.
• Features a single RISC QUICC Engine supporting programmable protocol termination and network interface functions.
• Includes a dedicated Security Engine providing hardware acceleration for encryption algorithms such as DES, AES, and SHA-1.
• Supports multiple communication protocols including Ethernet, HDLC, TDM, and USB 2.0 through Unified Communication Controllers.

Applications

• Residential gateways
• SOHO networks
• VPN routers
• Industrial control systems

Procurement Notes

Verify component authenticity and datasheet revision status due to end-of-life indications. Confirm availability of replacement sources as manufacturing may be discontinued. Ensure compatibility with existing board designs regarding voltage levels and pin configurations before procurement.

Selection Notes

Select this processor for applications requiring integrated networking capabilities and hardware security acceleration. Consider the e300c2 core performance limits and lack of FPU for computational requirements. Evaluate the PBGA-516 package constraints for PCB layout and thermal management in industrial environments.
