MPC8323CVRADDC

Overview

The MPC8323CVRADDC is a PowerQUICC II Pro integrated communications processor featuring an e300c2 core operating at 266 MHz. It includes 16 KB L1 instruction and data caches, a QUICC Engine with five UCCs, and a SEC 2.2 security engine. The device supports DDR1/DDR2 memory controllers, PCI 2.2 interfaces up to 66 MHz, USB 2.0, Ethernet, TDM, and UTOPIA. It operates within a 0°C to +105°C temperature range using a PBGA-516 package.

Feature Summary

• Integrates a single RISC version of the QUICC Engine 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 a unified communication controller architecture supporting multiple protocols including ATM, Ethernet, HDLC, and UART.
• Provides flexible system interfaces including a 32-bit PCI controller, local bus, and dual DDR memory controllers.

Applications

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

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm specific ordering suffixes match required voltage and temperature grades. Request original datasheets and test reports to validate electrical characteristics against design specifications before integration.

Selection Notes

Select this processor for applications requiring converged IP and ATM packet processing capabilities. Evaluate the e300c2 core performance against application computational needs. Ensure board design accommodates the PBGA-516 package constraints and power sequencing requirements for VDD and I/O supplies.

Part Context

This component belongs to the MPC8323E family of low-power PowerQUICC II Pro processors. It shares architectural similarities with the MPC8321 and MPC8321E but offers enhanced features such as UTOPIA support and additional communication controllers suitable for complex networking environments.
