MPC8260AZUMHBB

Overview

The MPC8260AZUMHBB is a PowerQUICC II integrated communications processor based on the .25μm HiP4 process. It features a dual-issue EC603e core operating up to 300 MHz with separate 16-Kbyte instruction and data caches. The device includes a Communications Processor Module (CPM) with 32-Kbyte dual-port RAM, multiple serial controllers, and a memory controller supporting DRAM and SDRAM. It utilizes a 480-pin TBGA package with separate 2.5 V core and 3.3 V I/O supplies.

Feature Summary

• Dual-issue integer 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 G2 core and CPM frequency optimization

Applications

• Network infrastructure equipment
• Telecommunications gateways
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized NXP channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level prior to assembly. Ensure PCB layout adheres to thermal resistance specifications to maintain junction temperature within operational limits during high-frequency operation.

Selection Notes

Select this model for applications requiring high-performance RISC processing combined with dedicated hardware communication handling. The independent clock domains allow optimized power consumption. Verify that the specific feature set of the MPC8260A variant matches the required peripheral count compared to superset devices like the MPC8266.

Part Context

This component belongs to the MPC826xA family, which includes the MPC8255, MPC8260, MPC8264, MPC8265, and MPC8266. These devices share the same core architecture but differ in peripheral availability such as PCI bridges or ATM TC layers. The MPC8260 serves as a baseline within this series for general communications processing.
