MPC8260AZUPIBB

Overview

The MPC8260AZUPIBB is a PowerQUICC II integrated communications processor based on the PowerPC G2 core. It features a dual-issue integer core with separate 16-Kbyte data and instruction caches, supporting frequencies up to 300 MHz. The device includes a Communications Processor Module (CPM) with a 32-Kbyte dual-port RAM, three Fast Communications Controllers (FCCs), two Multichannel Controllers (MCCs), four Serial Communications Controllers (SCCs), and two Serial Management Controllers (SMCs). It utilizes a 480-TBGA package.

Feature Summary

• Dual-issue PowerPC G2 core with floating-point unit and MMU
• Integrated Communications Processor Module for flexible protocol support
• Separate power supplies for internal logic and I/O
• Independent PLLs for core and CPM frequency optimization

Applications

• Telecommunications infrastructure equipment
• Network routing and switching systems
• ATM and Ethernet interface controllers
• Industrial control systems requiring high-speed serial communication

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified suppliers. Confirm RoHS compliance status as per current manufacturing revisions. Check for potential end-of-life notices or obsolescence warnings prior to finalizing procurement plans. Ensure supply chain documentation matches the specific ordering suffix requirements.

Selection Notes

Select this processor for applications requiring high-performance RISC processing combined with dedicated hardware-based communications handling. Evaluate thermal management needs due to significant power dissipation at higher clock speeds. Consider the availability of external memory interfaces and the specific peripheral set required by the target system architecture.

Part Context

This component belongs to the MPC826xA family, which includes variants like the MPC8255, MPC8264, MPC8265, and MPC8266. These devices share common architectural foundations but differ in specific peripheral counts and bridge capabilities. The MPC8260 serves as a foundational model within this series for embedded communications processing.

Replacement Considerations

Direct replacements include other members of the MPC826xA family such as the MPC8264, MPC8265, and MPC8266, depending on specific peripheral requirements. Verify pinout compatibility and software migration paths when transitioning between these variants.
