MPC8265AZUPIBC

Overview

The MPC8265AZUPIBC 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, operating at frequencies up to 300 MHz. The device includes a Communications Processor Module (CPM) for protocol handling, a 60x-to-PCI bridge supporting 66 MHz operation, and a twelve-bank memory controller. It utilizes a 480-ball TBGA package.

Feature Summary

• Integrated 60x-to-PCI bridge compliant with PCI Specification Revision 2.2
• Communications Processor Module with Fast Communications Controllers for Ethernet and ATM support
• Dual independent PLLs allowing separate frequency optimization for the core and CPM
• Twelve-bank memory controller with glueless interface to SRAM, SDRAM, and DRAM

Applications

• High-speed networking equipment requiring PCI connectivity
• ATM network infrastructure utilizing UTOPIA interfaces
• Embedded communication systems with TDM requirements
• Industrial control applications needing robust I/O management

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified secondary market suppliers. Confirm RoHS compliance status as historical documentation indicates non-compliance for specific manufacturing runs. Validate that the 480-TBGA package dimensions match your PCB footprint design. Ensure thermal management solutions account for the specified junction temperature limits during operation.

Selection Notes

Select this component when PCI bus integration is required alongside high-performance RISC processing. The MPC8265 offers a superset of features compared to the MPC8260, specifically adding the PCI bridge. Consider the separate power supply requirements for internal logic and I/O. Evaluate the need for the Communications Processor Module's specific protocol controllers against alternative microprocessors.

Part Context

This part belongs to the MPC826xA family, which includes the MPC8260, MPC8255, MPC8264, and MPC8266. These devices are .25μm HiP4 technology processors designed for communications applications. The MPC8265 specifically distinguishes itself by including the 60x-to-PCI bridge functionality not present in all family members.
