MPC8260AVVPIBB

Overview

The MPC8260AVVPIBB 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 RISC-based Communications Processor Module (CPM) for offloading peripheral tasks. Key interfaces include a 64-bit 60x bus, a 32-bit local bus, and multiple serial controllers such as Fast Communications Controllers (FCCs), Serial Communications Controllers (SCCs), and TDM ports. It utilizes a 480-pin TBGA package.

Procurement Notes

Verify the specific suffix AVVPIBB against official NXP documentation to confirm pinout, temperature range, and voltage specifications. Ensure compatibility with existing board designs regarding the 480-TBGA package dimensions and thermal requirements. Confirm that the component meets all necessary regulatory standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this processor for applications demanding high-speed data handling and protocol offloading via the CPM. Consider the 300 MHz operating frequency and the availability of dedicated serial interfaces like FCCs and TDM ports. Evaluate thermal management needs due to power dissipation characteristics at higher clock speeds. Ensure the system design supports the required 3.3V I/O and internal core voltage levels.

Part Context

This component belongs to the MPC826xA family within the PowerQUICC II series. It shares architectural similarities with the MPC8255, MPC8264, MPC8265, and MPC8266. The MPC8260A serves as a foundational model in this lineage, offering a balance of processing power and integrated communication capabilities suitable for embedded networking solutions.

Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers within the MPC82xx family. Verify functional equivalence regarding the G2 core, CPM configuration, and interface availability. Ensure any replacement maintains compatibility with the 480-TBGA footprint and electrical specifications.
