MPC8540CVT667JB

Overview

The MPC8540CVT667JB is a 32-bit embedded processor from the PowerQUICC III family, operating at a core frequency of 667 MHz. It integrates an e500 core with 32 KB L1 instruction and data caches, alongside a 256 KB L2 cache/SRAM. The device features two three-speed Ethernet controllers (TSECs), a RapidIO interface, PCI/PCI-X support, and a DDR SDRAM controller with ECC. It utilizes a 783-pin flip-chip plastic ball grid array package.

Feature Summary

• Integrates a high-performance 32-bit Book E-enhanced e500 core with dedicated memory management unit and enhanced debug capabilities.
• Includes a versatile 256 KB L2 cache/SRAM configurable for full caching, SRAM mapping, or mixed modes with ECC protection.
• Provides extensive connectivity via dual three-speed Ethernet controllers, a programmable RapidIO interface, and PCI/PCI-X bus controllers.
• Features an integrated four-channel DMA controller and OCeaN switch fabric for efficient packet switching and data movement.

Applications

• Networking infrastructure equipment
• Telecommunications transmission systems
• Wireless infrastructure applications

Procurement Notes

Verify that the specific suffix CVT667JB corresponds to the 667 MHz speed grade and commercial temperature range as defined in the official nomenclature guide. Confirm package compatibility with the 783-pin FC-PBGA footprint. Ensure power sequencing adheres to the recommended VDD before I/O supply guidelines to prevent device damage during initialization.

Selection Notes

Select this component when a balance of processing performance and integrated communication interfaces is required for control plane tasks. The e500 core architecture offers a mature software ecosystem. Consider the thermal dissipation requirements associated with the 1.2V core voltage and the specific I/O voltage levels for DDR and Ethernet interfaces during system design.

Part Context

This processor belongs to the PowerQUICC III series, designed for high-integration networking and telecom applications. It builds upon the Power Architecture technology, offering scalability within the family. The MPC8540 serves as an integrated host processor, combining CPU, memory controller, and peripheral interfaces on a single die to reduce system complexity.

Replacement Considerations

Consult the official NXP product selection guide for direct pin-compatible or functionally equivalent successors within the PowerQUICC III or subsequent generations. Verify architectural compatibility if migrating to newer e500 variants.
