MPC8272VRMIBA

Overview

The MPC8272VRMIBA is a PowerQUICC II integrated communications processor featuring a 32-bit G2_LE core operating at 266 MHz. It utilizes a 516-pin lead-free PBGA package (27x27 mm). The device integrates a modified Communications Processor Module (CPM), an embedded Security Engine (SEC) supporting DES, AES, and SHA-1, and dual Fast Ethernet MACs. It supports USB 2.0, PCI bus interfaces up to 66 MHz, and SDRAM/DRAM memory controllers.

Feature Summary

• Dual-processing architecture combining a PowerPC G2_LE core with a RISC-based Communications Processor Module for efficient task offloading.
• Integrated hardware security engine providing encryption capabilities for networking applications.
• High integration level reducing board space requirements through on-chip peripherals like PCI bridges and memory controllers.
• Flexible clock configuration allowing independent frequency optimization for the core and communication modules.

Applications

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

Procurement Notes

Verify component authenticity against NXP documentation due to end-of-life status. Confirm package type matches VR designation for lead-free specifications. Ensure compatibility with existing PCB footprints for the 516-pin PBGA format. Review errata sheets for known silicon revisions prior to final design implementation.

Selection Notes

Select this model when hardware security acceleration is required alongside high-speed serial communications. The integrated SEC distinguishes it from non-security variants in the family. Evaluate thermal management needs as power dissipation increases with higher bus frequencies. Consider the specific interface requirements of FCCs and SCCs for protocol support.

Part Context

This component belongs to the MPC8272 PowerQUICC II family, which includes the MPC8247, MPC8248, and MPC8271. These devices share the same core architecture but differ in peripheral availability, such as the presence or absence of the Security Engine. The VR suffix specifically denotes the lead-free plastic ball grid array packaging variant.

Replacement Considerations

Public confirmed substitute part numbers: MPC8272ZQ, MPC8248VR, MPC8271VR.
