MPC8248CVRMIBA

Overview

The MPC8248CVRMIBA is a PowerQUICC II family microprocessor featuring a dual-issue G2_LE core and an integrated security engine. It operates at frequencies up to 400 MHz with separate 16 KB instruction and data caches. The device includes a Communications Processor Module (CPM), USB 2.0 controller, PCI bridge, and two Fast Ethernet controllers. It utilizes a 516-pin lead-free PBGA package.

Feature Summary

• Integrated hardware security engine supporting DES, 3DES, MD-5, SHA-1, AES, PKEU, RNG, and RC-4 algorithms
• Dual-core architecture combining a Power Architecture core with a RISC-based Communications Processor Module
• Supports USB 2.0 full/low rate host and slave modes with flexible data buffers
• Includes a 60x-to-PCI bridge for high-speed peripheral connectivity

Applications

• Small and medium enterprise routers
• Virtual private network and firewall routers
• Wireless access points
• Residential gateways
• Imaging and industrial control equipment

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm package integrity and pin alignment prior to assembly. Review the latest errata sheet for known silicon revisions. Ensure power supply sequencing meets absolute maximum ratings to prevent damage during operation.

Selection Notes

Select this processor for applications requiring dedicated hardware encryption and protocol offloading via the CPM. The dual-power supply design optimizes performance while managing thermal output. Consider the specific interface requirements for PCI and Ethernet when designing the system bus architecture.

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 feature sets such as the presence of the security engine or ATM support. The MPC8248 specifically integrates the security engine unlike the MPC8271.
