MPC8270ZQMIBA

Overview

The MPC8270ZQMIBA is a 32-bit PowerQUICC II communications processor utilizing the G2_LE core. It operates at frequencies up to 266 MHz with a 1.45 V to 1.60 V core supply and 3.135 V to 3.465 V I/O supply. The device features 16 KB instruction and data caches, four Serial Communications Controllers (SCCs), three Fast Communication Controllers (FCCs), one Multi-Channel Controller (MCC), and an integrated PCI bridge. It supports USB 2.0 full/low rate and includes a floating-point unit.

Feature Summary

• Integrated dual-issue G2_LE microprocessor core with separate PLLs for core and CPM frequency optimization
• Communications Processor Module (CPM) supporting Ethernet, HDLC, ATM, and TDM protocols via FCCs, SCCs, and MCCs
• On-chip PCI bridge compliant with PCI Specification Revision 2.2 supporting streaming and DMA transfers
• USB 2.0 controller compatible with host and slave modes for full and low-speed data transfers

Applications

• Telecommunications infrastructure equipment requiring high-speed serial processing
• Network routing and switching systems utilizing PCI bus connectivity
• Industrial control applications needing robust real-time communication interfaces

Procurement Notes

Verify component authenticity through authorized NXP channels due to discontinued status. Confirm package integrity as the ZQ variant uses lead spheres. Ensure design compatibility with required voltage levels and thermal management specifications before integration.

Selection Notes

Select this model for applications requiring specific HiP7 process node characteristics within the PowerQUICC II family. Consider the ZQ package constraints regarding lead content and soldering profiles. Evaluate clock configuration requirements against available internal multipliers for optimal performance.

Part Context

This component belongs to the MPC8280 PowerQUICC II family, which also includes the MPC8275 and MPC8280. The MPC8270 variant specifically lacks UTOPIA ports and Transmission Convergence layers found in higher-end models. It shares the same 516-pin PBGA package form factor as other VR and ZQ devices in the series.
