MPC8540VT667LC

Overview

The MPC8540VT667LC is a 32-bit embedded processor from the PowerQUICC III family, featuring an e500 core operating at 667 MHz. It integrates a 256-Kbyte L2 cache/SRAM, DDR SDRAM controller with ECC support, and high-speed interfaces including RapidIO, PCI/PCI-X, and dual three-speed Ethernet controllers. The device 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
• Features configurable 256-Kbyte L2 cache/SRAM block supporting full ECC protection
• Includes integrated OCeaN switch fabric for packet prioritization and starvation avoidance
• Supports multiple industry-standard interfaces including RapidIO, PCI/PCI-X, and TSEC

Applications

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

Procurement Notes

Verify that the specific suffix VT667 corresponds to the required 667 MHz speed grade and commercial temperature range. Confirm the FC-PBGA-783 package dimensions match the PCB footprint design. Ensure power sequencing requirements for VDD and I/O supplies are strictly followed during system integration.

Selection Notes

Select this component when a balance of processing performance and integrated connectivity is required for control plane tasks. The device supports both cache and SRAM modes for the L2 block, offering flexibility for deterministic latency or large data buffering needs in embedded networking environments.

Part Context

This processor belongs to the PowerQUICC III family, designed for communications processing. It combines system-level support for standard interfaces with the embedded category of Power Architecture technology. The device is intended to handle complex computational tasks while managing high-speed I/O throughput.

Replacement Considerations

Consult official documentation for successor models within the PowerQUICC III family, such as the MPC8541E or MPC8543E, which offer enhanced features like DDR2 support and higher clock speeds.
