MPC8265AVVPJDC

Overview

The MPC8265AVVPJDC is a PowerQUICC II integrated communications processor featuring an EC603e core operating at frequencies up to 300 MHz. It utilizes a .25μm HiP4 process and includes a Communications Processor Module (CPM) with 32 Kbytes of dual-port RAM. The device supports a 64-bit 60x bus, a 32-bit local bus, and integrates a PCI bridge compliant with Specification Revision 2.2 supporting 66 MHz operation. It employs separate power supplies for internal logic and I/O, housed in a TBGA-480 package.

Feature Summary

• Integrated PCI host bridge supporting 66 MHz operation and DMA transfers
• Dual-issue integer core with floating-point unit and separate instruction/data caches
• Communications Processor Module providing flexible protocol support including Ethernet and ATM
• Independent clock multipliers allowing distinct core and CPM frequency optimization

Applications

• High-end communications and networking equipment
• Routers and DSLAMs
• Telecom switching equipment
• Cellular base stations

Procurement Notes

Verify the specific suffix AVVPJDC against the official NXP ordering guide to confirm package type, temperature range, and lead-free status. Confirm that the component meets RoHS requirements if applicable to your assembly process. Check for end-of-life notifications as this family may be discontinued. Ensure voltage tracking between VDD, VCCSYN, and VDDH during power-on reset sequences.

Selection Notes

Select this processor for applications requiring high-performance layer 2 forwarding combined with control plane processing. The integrated PCI bridge distinguishes it from other MPC826xA variants lacking this feature. Consider the separate PLL capabilities for optimizing power consumption by decoupling core and peripheral clock speeds. Verify memory controller compatibility with your target SRAM or SDRAM components.

Part Context

This component belongs to the MPC826xA family, which includes the MPC8260, MPC8255, MPC8264, and MPC8266. These devices are built on the PowerQUICC II architecture using .25μm HiP4 technology. The MPC8265 specifically adds a PCI bridge compared to the base MPC8260 model, enhancing its utility in systems requiring external bus connectivity.
