MPC8260AZUMHBB

Overview

The MPC8260AZUMHBB is a PowerQUICC II integrated communications processor based on the PowerPC G2 core. It features a single 32-bit core operating at 166MHz within a 480-TBGA package (37.5x37.5 mm). The device includes a Communications Processor Module (CPM) for protocol handling, alongside integrated DRAM and SDRAM controllers. Connectivity options include 10/100 Mbps Ethernet and various serial interfaces such as I2C, SPI, UART, USART, SCC, and SMC. It supports an I/O voltage of 3.3V and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Integrates a PowerPC G2 core with a dedicated Communications Processor Module for hardware-accelerated protocol processing.
• Provides high-speed networking capabilities through integrated 10/100 Mbps Ethernet MACs.
• Supports external memory expansion via built-in controllers for both DRAM and SDRAM.
• Offers extensive peripheral connectivity including multiple serial communication ports and standard bus interfaces.

Applications

• Network interface cards for telecommunications infrastructure
• Digital Subscriber Line Access Multiplexers (DSLAMs)
• Routers and media gateways
• Integrated Access Devices (IADs)

Procurement Notes

Verify component authenticity and physical condition upon receipt, as this part is obsolete. Confirm that the specific suffix matches the required pinout and electrical characteristics against official datasheets. Ensure proper ESD handling procedures are followed during installation due to the fine-pitch TBGA packaging. Check for moisture sensitivity level compliance prior to soldering.

Selection Notes

Select this processor for applications requiring robust hardware-based protocol offloading and reliable network connectivity in industrial or telecom environments. Consider the 166MHz performance and integrated CPM for complex packet processing tasks. Evaluate the 480-TBGA package constraints for PCB layout and thermal management requirements compared to alternative packages in the MPC82xx family.

Part Context

This component belongs to the Freescale MPC82xx series, specifically the PowerQUICC II family designed for embedded communications. These processors were engineered to address the needs of networking and wireless infrastructure markets by combining high-performance RISC processing with specialized hardware accelerators for data plane functions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the MPC8260A series is generally obsolete, consult manufacturer resources for current generation alternatives or verify compatibility with legacy system designs.
