MPC8271CVRMIBA

Overview

The MPC8271CVRMIBA is a PowerQUICC II microprocessor featuring a G2_LE core and a Communications Processor Module (CPM). It operates at frequencies up to 266 MHz with a 32-bit data bus width. The device utilizes a 516-pin PBGA package and supports an operating temperature range of 0°C to 105°C. Key interfaces include PCI, USB 2.0, Ethernet, UTOPIA, I2C, and SPI. It includes 16 KB instruction and data caches, a floating-point unit, and lacks the integrated security engine found in other family members.

Feature Summary

• Dual-core architecture combining a Power Architecture core with a RISC-based Communications Processor Module for efficient task distribution.
• Integrated hardware support for multiple communication protocols including Ethernet, HDLC, ATM via UTOPIA, and USB 2.0.
• Flexible clock configuration allowing independent operation of the core and CPM for optimized power and performance.
• Comprehensive memory controller supporting SRAM, SDRAM, DRAM, and Flash with glueless interface capabilities.

Applications

• Networking equipment such as small and medium enterprise routers
• Virtual private network (VPN) and firewall routers
• Wireless access points and residential gateways
• xDSL equipment and imaging systems

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Review the latest errata sheet for known silicon revisions. Ensure supply chain partners provide traceability documentation. Validate that the specific VR package variant matches design requirements.

Selection Notes

Select this model when high integration of serial communications controllers and PCI connectivity is required without the need for the dedicated security engine. Compare against MPC8247 for similar feature sets or MPC8272 if hardware encryption algorithms are necessary. Consider the 516-pin PBGA footprint constraints and thermal management requirements for the chosen application environment.

Part Context

This component belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8248, and MPC8247. These devices share a common architectural foundation but differ in peripheral availability, specifically regarding the Security Engine and ATM support. The MPC8271 sits between the MPC8247 and MPC8272 in terms of feature set, offering UTOPIA support but omitting the SEC block.

Replacement Considerations

Public confirmed substitute part numbers: None available. The device is listed as End-of-Life with no direct cross-reference provided in official documentation.
