MPC8280CVVQLDA

Overview

The MPC8280CVVQLDA is a PowerQUICC II integrated communications processor manufactured by NXP USA Inc. It utilizes the G2_LE core, an EC603e variant, operating at frequencies up to 450 MHz with a Communications Processor Module (CPM) running up to 300 MHz. The device features a 64-bit data and 32-bit address 60x bus, a 32-bit local bus, and a PCI bridge supporting up to 66 MHz. Key peripherals include three Fast Communication Controllers (FCCs), four Serial Communication Controllers (SCCs), two Multi-Channel Controllers (MCCs), and a USB 2.0 controller. It employs HiPerMOS7 0.13-micron technology in a lead-free 480-pin TBGA package.

Feature Summary

• Integrated dual-issue G2_LE core with separate instruction and data caches for high-performance processing.
• Dedicated Communications Processor Module (CPM) offloads protocol handling from the main core.
• Supports multiple communication protocols including Ethernet, ATM, HDLC, and USB via specialized controllers.
• Features independent power supplies and PLLs for the core and I/O to optimize performance and power consumption.

Applications

• High-end wired and wireless infrastructure communications processing
• Routers and DSLAMs requiring integrated control and forwarding plane processing
• Telecom switching equipment and cellular base stations

Procurement Notes

Verify the specific silicon revision and mask number against project requirements, as electrical characteristics may vary between revisions. Confirm that the lead-free VV package designation aligns with environmental compliance standards. Ensure the ordering suffix matches the exact pinout and feature set required, as variations exist within the MPC8280 family.

Selection Notes

Select this component when high integration of serial interfaces and ATM support is required alongside a powerful RISC core. Consider the 480 TBGA package constraints for PCB layout. Evaluate thermal management needs based on the estimated power dissipation tables provided in the hardware specifications, particularly for high-frequency configurations.

Part Context

This part belongs to the PowerQUICC II family, which includes the MPC8270 and MPC8275. The MPC8280 represents the high-performance end of this generation, distinguished by its additional UTOPIA ports, Transmission Convergence layer, and Inverse Multiplexing for ATM capabilities not present in lower-tier models like the MPC8270.
