MPC8280VVQLDA

Overview

The MPC8280VVQLDA is a PowerQUICC II integrated communications processor manufactured by NXP USA Inc. It utilizes the G2_LE core and features a 480-pin lead-free TBGA package (37.5 x 37.5 mm). The device supports system core frequencies ranging from 166 MHz to 450 MHz, with internal clock multipliers allowing for various bus ratios. It includes a Communications Processor Module (CPM) capable of running at different frequencies than the core. Key hardware components include a 60x-to-PCI bridge, USB 2.0 controller, three Fast Communication Controllers (FCCs), four Serial Communication Controllers (SCCs), two Multi-channel Controllers (MCCs), and Transmission Convergence (TC) layer support.

Feature Summary

• Dual-issue integer G2_LE core with separate 16 KB instruction and data caches
• Integrated Communications Processor Module (CPM) supporting multiple protocols including Ethernet, ATM, and HDLC
• On-chip PCI bridge compliant with PCI Specification Revision 2.2
• Universal Serial Bus (USB) 2.0 full/low rate controller

Applications

• Wired and wireless infrastructure communications processing
• High-end routers and DSLAMs
• Telecom switching equipment and cellular base stations
• Remote access concentrators

Procurement Notes

Verify the specific suffix 'VVQLDA' against official documentation to confirm lead-free status and package type. Ensure compatibility with existing board designs regarding the 480-TBGA footprint and voltage requirements. Confirm availability as this component may be subject to end-of-life notices or obsolescence warnings.

Selection Notes

Select this processor for applications requiring high-performance embedded control and forwarding plane processing in networking equipment. Consider the available package options and frequency ranges when designing power delivery systems. Verify that the required communication protocols, such as ATM UTOPIA interfaces, are supported by the specific device variant chosen.

Part Context

This component belongs to the MPC82xx family of PowerQUICC II processors. These devices are designed using HiPerMOS7 0.13-micron process technology. The family offers various performance and package options, including standard ZU/VV packages and alternate VR/ZQ packages, to suit different system integration needs.

Replacement Considerations

Check for direct substitutes within the MPC82xx family, such as the MPC8275 or MPC8270, noting differences in feature sets like UTOPIA ports and MCC counts. Verify pinout and software compatibility before transitioning to alternative part numbers.
