MPC8271ZQTIEA

Overview

The MPC8271ZQTIEA is a member of the PowerQUICC II family, featuring a 32-bit G2_LE core (MPC603e) with an integrated floating-point unit. It operates at frequencies up to 266 MHz and utilizes a 516-pin PBGA package with lead spheres. The device includes a modified Communications Processor Module (CPM), a PCI bridge supporting 66 MHz, two Ethernet ports, and a USB 2.0 controller. It supports separate power supplies for internal logic (1.425 V to 2.25 V) and I/O (3.135 V to 3.465 V).

Feature Summary

• Integrated G2_LE core with floating-point arithmetic support and separate instruction/data caches.
• Modified Communications Processor Module (CPM) providing flexible serial communication interfaces.
• On-chip PCI bridge compliant with PCI Specification revision 2.2.
• Dual Fast Communication Controllers (FCCs) supporting Ethernet and ATM protocols.

Applications

• Communications processors
• Network infrastructure equipment
• Industrial control systems

Procurement Notes

Verify that the ZQ suffix corresponds to the lead sphere package variant as specified in official documentation. Confirm the TIEA suffix details against the manufacturer's ordering guide. Ensure compatibility with required voltage levels and thermal management solutions for the specific operating environment.

Selection Notes

Select this component when a Power Architecture core with integrated communications capabilities is required. Consider the availability of the CPM for handling complex serial protocols. Evaluate the need for the specific 516-pin BGA package and lead sphere construction for board integration requirements.

Part Context

This part belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8248, and MPC8247. These devices share common architectural features but differ in specific functionalities such as the presence of a Security Engine or ATM support. The MPC8271 specifically lacks the Security Engine found in the MPC8272/8248.

Replacement Considerations
