MPC8280ZUQLDA

Overview

The MPC8280ZUQLDA is a PowerQUICC II family communications processor manufactured by NXP USA Inc. It utilizes the G2_LE core, a version of the EC603e microprocessor, operating at frequencies up to 450 MHz. The device features a dual-issue integer core with separate 16 KB instruction and data caches. It integrates a Communications Processor Module (CPM) with two Fast Communication Controllers (FCCs), four Serial Communication Controllers (SCCs), two Multi-Channel Controllers (MCCs), and one Serial Management Controller (SMC). Connectivity includes three 10/100 Mbps Ethernet ports, a PCI bridge supporting up to 66 MHz, USB 2.0 full/low rate, and UTOPIA II ports. The processor is housed in a 480-pin TBGA package.

Feature Summary

• Dual-issue G2_LE core with floating-point unit and separate power supplies for internal logic and I/O
• Integrated Communications Processor Module (CPM) handling serial protocols including HDLC, ATM, and Ethernet
• PCI bridge compliant with Specification Revision 2.2, supporting DMA and hot-swap capabilities
• System Interface Unit (SIU) providing clock synthesis, reset control, and real-time clock functions

Applications

• Telecommunications equipment requiring high-speed serial communication processing
• Network infrastructure devices utilizing PCI bus connectivity
• Systems implementing ATM transmission convergence layer protocols

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation, noting potential variations based on manufacturing date. Ensure proper ESD handling procedures are followed during storage and installation. Validate that the specific ZU package variant matches design requirements for leaded solder compatibility.

Selection Notes

Select this model when high-performance PowerPC processing combined with extensive communication peripherals is required. Consider the G2_LE core frequency range and CPM capabilities for protocol offloading. Evaluate thermal management needs due to power dissipation characteristics. Ensure PCB layout supports the 480-TBGA package dimensions and pin pitch specifications.

Part Context

The MPC8280 belongs to the PowerQUICC II family, designed for embedded communications applications. It represents an evolution in the MPC82xx series, offering enhanced processing speeds and integrated communication modules compared to earlier generations. The ZU suffix denotes a specific 480-pin TBGA package configuration within the broader product line.

Replacement Considerations

Public confirmed substitute part numbers include MPC8280CVVUPEA, MPC8280CZUQLDA, and MPC8275VR. Verify functional equivalence regarding peripheral availability and pinout compatibility before migration.
