MPC8265AZUPJDC

Overview

The MPC8265AZUPJDC is a PowerQUICC II integrated communications processor featuring a dual-issue EC603e core operating at 150–300 MHz. It includes separate 16-Kbyte data and instruction caches, a floating-point unit, and a 32-bit RISC Communications Processor Module (CPM). Key interfaces include a 64-bit 60x bus, a 32-bit local bus, and a PCI bridge supporting up to 66 MHz. The device integrates twelve-bank memory controller, multiple serial controllers (FCC, SCC, SMC), TDM ports, and an I2C interface.

Feature Summary

• Integrated PCI host bridge and agent with DMA capabilities for memory block transfers
• Dual independent PLLs allowing separate frequency optimization for the G2 core and CPM
• Embedded 32-bit RISC microcontroller with 32-Kbyte dual-port RAM for protocol processing
• Comprehensive serial communication suite including Ethernet, ATM, HDLC, and TDM support

Applications

• Telecommunications infrastructure equipment requiring high-speed packet processing
• Network routers and switches utilizing PCI connectivity for system integration
• ATM network nodes leveraging UTOPIA interfaces and TC layer hardware
• Industrial control systems employing real-time clock and watchdog timer features

Procurement Notes

Verify the specific suffix 'ZUPJDC' against official NXP/Freescale documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing board designs regarding the 480 TBGA footprint and voltage requirements. Cross-reference the document number MPC8260AEC Rev 2.0 for accurate electrical characteristics and thermal limits before finalizing procurement specifications.

Selection Notes

Select this component when PCI bus integration is required alongside high-performance PowerPC processing. The MPC8265 provides a superset of features compared to the MPC8260, specifically adding the PCI bridge. Evaluate power consumption profiles based on the selected core-to-bus clock multipliers and ambient temperature conditions. Confirm that the available serial interfaces meet the specific protocol requirements of the target application.

Part Context

This part belongs to the MPC826xA family of PowerQUICC II processors manufactured by Freescale Semiconductor (now NXP). The MPC8265 serves as an intermediate model within the series, offering more communication resources than the base MPC8260 but lacking some advanced ATM features found in the MPC8266. It is designed for embedded communications applications requiring robust networking capabilities.

Replacement Considerations

The MPC8260AEC datasheet identifies the MPC8260, MPC8255, MPC8264, and MPC8266 as members of the same family. Substitution requires careful evaluation of feature availability, such as the presence or absence of the PCI bridge and specific serial controllers. Pinout and software compatibility should be verified against the specific functional differences documented for each variant.
