MPC8248VRMIBA

Overview

The MPC8248VRMIBA is a PowerQUICC II integrated communications processor featuring a dual-issue G2_LE core and an embedded Communications Processor Module (CPM). It includes an integrated Security Engine (SEC) supporting hardware encryption algorithms. The device utilizes a 516-pin lead-free PBGA package, operates at frequencies up to 400 MHz, and supports separate power supplies for internal logic and I/O.

Feature Summary

• Dual-core architecture combining a Power Architecture core with a RISC-based CPM for balanced processing tasks
• Integrated security engine providing hardware acceleration for DES, 3DES, AES, MD-5, SHA-1, and RC-4
• Supports USB 2.0 full/low rate compatibility with host and slave mode capabilities
• Includes a PCI bridge compliant with PCI Specification revision 2.2

Applications

• Small and medium enterprise routers
• Virtual private network (VPN) and firewall routers
• Wireless access points
• Residential gateways
• xDSL equipment

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm component authenticity through authorized channels as this part may be subject to obsolescence or limited availability. Ensure design-in compliance with recommended operating conditions for voltage and thermal management.

Selection Notes

Select this component for applications requiring high integration of networking protocols and hardware security. The dual-core design allows offloading of peripheral communications tasks from the main processor. Verify interface requirements for Ethernet, PCI, and USB against system specifications before implementation.

Part Context

This device belongs to the MPC8272 family of PowerQUICC II processors. It shares architectural similarities with the MPC8272, MPC8271, and MPC8247, differing primarily in feature sets such as the presence of the Security Engine and ATM support. The VR suffix indicates a lead-free 516-pin PBGA package.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers within the MPC8272 family. Verify pinout and feature compatibility before considering alternatives.
