MPC8323ECVRADDCA

Overview

The MPC8323ECVRADDCA 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 supporting up to 266 MHz. The device provides a 32-bit PCI interface up to 66 MHz, USB 2.0, TDM, and UTOPIA interfaces. It operates within a junction temperature range of 0 to 105 °C and utilizes a PBGA-516 package.

Feature Summary

• Integrates a single e300c2 core with dual integer units and on-chip MMUs for high-performance data-plane processing.
• Features a QUICC Engine block with five Universal Communication Controllers (UCCs) supporting Ethernet, ATM, HDLC, and TDM protocols.
• Includes a dedicated Security Engine (SEC 2.2) providing hardware acceleration for DES, AES, and SHA algorithms.
• Supports flexible memory configurations via a 32-bit DDR1/DDR2 SDRAM controller and a 32-bit PCI interface.

Applications

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

Procurement Notes

Verify the specific suffix 'VRADDCA' against official NXP documentation to confirm the exact clock frequency, I/O voltage levels, and commercial temperature range. Ensure compatibility with existing board designs regarding power sequencing and signal integrity requirements before procurement.

Selection Notes

Select this component for applications requiring converged IP and ATM packet processing. Evaluate the need for the QUICC Engine's protocol termination capabilities versus CPU load. Confirm that the required peripheral interfaces, such as UTOPIA and multiple Ethernet ports, align with the system architecture.
