MPC8248CVRPIEA

Overview

The MPC8248CVRPIEA is a PowerQUICC II integrated communications processor featuring a 32-bit G2_LE core operating at frequencies up to 400 MHz. It utilizes a 516-pin lead-free PBGA package and includes an integrated security engine supporting DES, 3DES, AES, MD-5, SHA-1, and RC-4 algorithms. The device incorporates a Communications Processor Module (CPM) with dual Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), and a USB 2.0 controller. It supports a 32-bit PCI interface running up to 66 MHz and provides separate power supplies for internal logic and I/O.

Feature Summary

• Integrated hardware security engine for encryption and hashing
• Dual processing blocks combining embedded Power Architecture core and RISC-based CPM
• Support for multiple communication protocols including Ethernet, HDLC, ATM, and USB 2.0
• Flexible clock configuration allowing independent core and CPM frequency optimization

Applications

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

Procurement Notes

Verify the specific ordering suffix 'IEA' against official NXP documentation to confirm temperature range and packaging details. Confirm current product lifecycle status as this component may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing board designs regarding the 516-pin PBGA footprint and voltage requirements before procurement.

Selection Notes

Select this processor for applications requiring high integration of networking peripherals and hardware security within a small form factor. Consider the dual-core architecture for offloading communication tasks from the main processor. Evaluate thermal management needs based on the estimated power dissipation profiles provided in the datasheet. Ensure the system design accommodates the separate power supply requirements for the core and I/O interfaces.

Part Context

This component belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8271, and MPC8247. These devices share a common architectural foundation but differ in peripheral availability, such as the presence of the security engine in the MPC8248 and MPC8272 models. The VR package designation indicates a lead-free plastic ball grid array construction.

Replacement Considerations

Direct replacements within the same family include the MPC8247, though it lacks the integrated security engine. The MPC8272 offers identical functionality but may have different performance characteristics or availability. Verify pin-to-pin compatibility and software compatibility when considering these alternatives.
