MPC8271CZQTIEA

Overview

The MPC8271CZQTIEA is a 32-bit microprocessor from the PowerQUICC II family, utilizing the PowerPC 603e core. It operates at a maximum clock frequency of 400 MHz and features an integrated floating-point unit. The device supports external memory interfaces for DRAM, SRAM, and SDRAM. Key communication peripherals include PCI, USB, Ethernet, I2C, CPM, and UTOPIA interfaces. It is housed in a PBGA-516 package with surface-mount installation. The component functions within a voltage range of 1.425 V to 2.25 V for core operation and 3.135 V to 3.465 V for I/O, supporting commercial to industrial temperature ranges.

Feature Summary

• Integrates a high-performance PowerPC 603e processor core with floating-point capabilities for complex computation tasks.
• Provides comprehensive connectivity through built-in PCI, USB, Ethernet, and serial peripheral interfaces.
• Includes a Communications Processor Module (CPM) to offload protocol processing and manage data traffic efficiently.

Applications

• Telecommunications infrastructure equipment requiring high-speed packet processing
• Network routers and switches utilizing PCI and Ethernet interfaces
• Industrial control systems operating in extended temperature environments

Procurement Notes

Verify the specific suffix codes against official NXP documentation to confirm pin compatibility and feature sets. Confirm that the requested revision matches the design requirements for voltage levels and interface configurations. Ensure that the supply chain source provides valid traceability for this discontinued component series.

Selection Notes

Select this component when a dedicated communications processor with hardware acceleration for networking protocols is required. The integration of the CPM reduces host CPU load for serial communications. Consider the PBGA-516 footprint constraints and thermal management requirements associated with the 400 MHz operation speed during board layout.
