MPC8280CZUUPEA

Overview

The MPC8280CZUUPEA is a PowerQUICC II family communications processor featuring a dual-issue G2_LE core operating at frequencies up to 450 MHz. It integrates a 32-bit RISC Communication Processor Module (CPM), PCI bridge, USB 2.0 controller, and three 10/100 Ethernet MACs. The device includes two UTOPIA II ports, two Multi-Channel Controllers (MCCs), Transmission Convergence (TC) layer hardware, and Inverse Multiplexing for ATM (IMA). It utilizes a 480-pin TBGA package with leaded solder.

Feature Summary

• Dual-issue integer core with separate 16 KB instruction and data caches
• Integrated Communications Processor Module supporting multiple serial protocols
• PCI bus interface compliant with Specification Revision 2.2
• Transmission convergence layer and inverse multiplexing capabilities

Applications

• High-speed network routing and switching equipment
• Asynchronous Transfer Mode (ATM) infrastructure devices
• Time Division Multiplexing (TDM) telecommunications systems
• Industrial control processors requiring robust serial interfaces

Procurement Notes

Verify the specific suffix 'CZU' indicates the 480-pin TBGA package with leaded solder composition. Confirm that the component meets the required environmental specifications for your application, as this part may be subject to end-of-life status or RoHS compliance variations depending on the manufacturing date code.

Selection Notes

Select this processor when high-performance serial communication processing is required alongside standard PCI connectivity. Ensure the design supports the necessary power supply rails for both internal logic and I/O. Consider thermal management requirements given the estimated power dissipation values associated with higher clock speeds and active peripheral usage.

Part Context

This component belongs to the Freescale/NXP PowerQUICC II family of integrated communications processors. It shares architectural similarities with the MPC8270 and MPC8275 but offers expanded serial communication resources, including additional TDM ports and specialized ATM handling hardware not present in lower-tier variants.

Replacement Considerations

Compatible substitutes within the same family include the MPC8280CVVUPEA, which features a lead-free package variant. Other members like the MPC8270 offer similar functionality with reduced serial controller counts.
