MPC8349VVALFB

Overview

The MPC8349VVALFB is a PowerQUICC II Pro integrated host processor based on the e300 core. It operates at up to 667 MHz with 1260 MIPS performance. The device features dual three-speed Ethernet controllers, dual PCI interfaces, and a hardware security engine supporting DES, AES, and RSA algorithms. Memory support includes DDR1/DDR2 SDRAM via a 32- or 64-bit interface with ECC. Additional peripherals include dual USB controllers, a local bus controller, and standard communication interfaces.

Feature Summary

• Integrated e300 superscalar processor core with floating-point capabilities
• Dual three-speed Ethernet controllers for network routing applications
• Hardware security engine for encryption and authentication protocols
• Dual PCI interfaces supporting host and agent modes

Applications

• Ethernet routers and switches
• Wireless LAN devices
• Network storage systems
• Industrial control equipment

Procurement Notes

Verify silicon revision compatibility before integration. This document covers revision 3.x silicon and later; earlier revisions require separate documentation. Confirm voltage requirements match system design specifications. Ensure proper power sequencing during initialization to prevent excessive current draw. Check for published errata relevant to the specific silicon version.

Selection Notes

Select this component for high-performance embedded networking tasks requiring hardware acceleration. The integrated security engine reduces reliance on external cryptographic modules. Dual PCI interfaces provide flexibility for peripheral expansion. Verify memory interface compatibility with target DDR1 or DDR2 components. Consider thermal dissipation requirements for maximum frequency operation.

Part Context

This processor belongs to the PowerQUICC II Pro family, representing an evolution of the PowerQUICC II series. It utilizes the e300 SoC platform, which enhances the previous 603e core with larger caches and improved performance. The architecture maintains software compatibility with existing Power Architecture implementations while adding advanced connectivity features.

Replacement Considerations

MPC8347E: Similar processor with single PCI interface instead of dual. MPC8343E: Lower clock speed variant operating at 400 MHz. Both share the same e300 core architecture and pinout but differ in specific peripheral configurations.
