MPC8271VRMIBA

Overview

The MPC8271VRMIBA is a PowerQUICC II microprocessor featuring a 32-bit G2_LE core operating at 266 MHz. It utilizes a 516-pin PBGA package and supports external memory types including DRAM, SRAM, and SDRAM. The device integrates a Communications Processor Module (CPM) with UTOPIA II ports, two Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), and two USB 2.0 interfaces. It operates within an ambient temperature range of 0°C to 105°C.

Feature Summary

• Integrated Communications Processor Module (CPM) supporting UTOPIA II protocols for high-speed serial communication.
• Dual-issue integer G2_LE core architecture providing efficient instruction processing capabilities.
• Comprehensive peripheral set including Ethernet controllers, PCI bridge, and USB 2.0 full/low rate support.

Applications

• Telecommunications infrastructure equipment
• Network routing and switching devices
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm specific lot traceability and storage history requirements. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet. Validate that replacement components meet identical electrical and mechanical specifications.

Selection Notes

Select this component when system requirements demand integrated communications processing alongside a standard PowerPC core. Evaluate thermal management needs based on estimated power dissipation profiles. Consider the availability of development tools compatible with the G2_LE architecture. Assess pinout compatibility with existing PCB layouts requiring the 516-pin PBGA form factor.

Part Context

This part belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8248, and MPC8247. While sharing the same core and package options, the MPC8271 distinguishes itself by omitting the integrated Security Engine found in the MPC8272 and MPC8248 variants. It retains the CPM and UTOPIA interface features common to the higher-end models.

Replacement Considerations

Direct substitutes include other members of the MPC82xx family such as the MPC8272CVRMIBA or MPC8275VRMIBA, provided the absence of the Security Engine does not impact security requirements. Verify functional equivalence regarding the CPM configuration and peripheral availability before implementation.
