MPC8260ACZUMIBB

Overview

The MPC8260ACZUMIBB is a PowerQUICC II integrated communications processor manufactured by NXP USA Inc. It features a single-core, 32-bit PowerPC G2 architecture operating at 266 MHz. The device utilizes a 480-TBGA package with dimensions of 37.5x37.5 mm and supports I/O voltages of 3.3V. Key interfaces include three 10/100 Mbps Ethernet ports via MII, UTOPIA ports, and standard serial protocols such as I2C, SPI, UART, and USART.

Feature Summary

• Integrates a high-performance dual-issue EC603e core with separate instruction and data caches for efficient processing.
• Includes a dedicated Communications Processor Module (CPM) to offload peripheral tasks and support multiple communication protocols.
• Provides flexible clock configuration with independent PLLs for the core and CPM to optimize power and performance.
• Features a comprehensive memory controller supporting various external memory types including SDRAM and DRAM.

Applications

• Wired and wireless infrastructure communications processing
• High-end networking equipment such as routers and DSLAMs
• Telecom switching equipment and cellular base stations

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental certifications required for your region. Ensure proper handling procedures are followed due to moisture sensitivity levels. Review datasheet specifications carefully to match voltage and thermal requirements before integration into final designs.

Selection Notes

Select this processor for applications requiring robust embedded control alongside heavy communications protocol handling. The separation of the G2 core and CPM allows for optimized resource allocation. Consider the available interface options like Ethernet and UTOPIA when designing system connectivity. Evaluate thermal management needs based on the estimated power dissipation figures provided in the hardware specifications.
