MPC8540CPX667JC

Overview

The MPC8540CPX667JC is a 32-bit embedded processor from the PowerQUICC III family, manufactured by NXP USA Inc. It features an e500 core operating at 667 MHz with a 166 MHz system clock (SYSCLK). The device integrates 32 KB L1 instruction and data caches, alongside a configurable 256 KB L2 cache/SRAM. Connectivity includes two three-speed Ethernet controllers (TSECs), a PCI/PCI-X controller, a RapidIO interface, and a local bus. It utilizes a 783-pin flip-chip plastic ball grid array (FC-PBGA) package.

Feature Summary

• Integrates a high-performance 32-bit Book E-enhanced e500 core with dedicated memory management unit and enhanced debug support.
• Features a programmable OCeaN switch fabric for packet switching and four-channel DMA controller supporting scatter-gather transfers.
• Includes dual three-speed Ethernet controllers compliant with IEEE standards and a RapidIO interface supporting atomic operations.
• Provides integrated DDR SDRAM controller with full ECC support and PCI/PCI-X controller compatible with PCI 2.2 and PCI-X 1.0.

Applications

• Networking infrastructure applications
• Telecommunications equipment
• Wireless infrastructure systems

Procurement Notes

Verify the specific speed grade suffix '667' to confirm the 667 MHz core frequency rating. Ensure the 'JC' suffix matches the required commercial temperature range specifications. Confirm the 783-FCPBGA package dimensions against the target PCB footprint. Cross-reference the datasheet revision to ensure compatibility with current errata documents.

Selection Notes

Select this component when a 32-bit architecture with integrated networking interfaces is required. The 667 MHz speed grade offers a balance between processing throughput and power consumption compared to higher-frequency variants. Consider the available L2 cache configuration options if deterministic latency or large memory mapping is needed for the application.
