MPC8260AZUPIBB

Overview

The MPC8260AZUPIBB is a PowerQUICC II integrated communications processor manufactured by Freescale Semiconductor. It features a 32-bit RISC core operating at 300 MHz with an external clock frequency of 66.66 MHz. The device utilizes a 480-pin Thin Ball Grid Array (TBGA) package measuring 37.5 x 37.5 mm. Key specifications include a 32-bit address bus, a 64-bit external data bus, and integrated floating-point formatting capabilities.

Feature Summary

• Integrated PCI interface for host connectivity
• Built-in USB controller support
• Dedicated Communications Processor Module (CPM)
• Hardware-accelerated HDLC processing

Applications

• High-speed router platforms
• Network switch infrastructure
• Telecommunications base station controllers
• Industrial automation gateways

Procurement Notes

Verify the specific suffix 'ZUPIBB' against official NXP/Freescale documentation to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the manufacturing date code with current lifecycle status, as this part may be subject to obsolescence notices.

Selection Notes

Select this processor when high-throughput packet processing and hardware offloading are required. The integrated CPM reduces CPU load by handling serial protocols independently. Consider the 300 MHz performance ceiling and TBGA thermal dissipation limits during system design. Evaluate memory bandwidth requirements given the 64-bit external data bus architecture.

Part Context

This component belongs to the PowerQUICC II family, designed for embedded networking applications. It combines a PowerPC-compatible core with specialized peripherals for communication tasks. The HiP4 process technology enables efficient power consumption relative to performance. Similar parts in the series include the MPC8264 and MPC8265.

Replacement Considerations

Official substitutes within the same family include the MPC8264 and MPC8265. Verify pin-to-pin compatibility and software register mapping before substitution. Consult the latest hardware specification document for any functional differences between revisions.
