• Dual three-speed Ethernet controllers supporting 10/100/1000 Mbps
• Dual PCI interfaces compliant with PCI Specification Revision 2.3
• Integrated security engine for IPSec, SSL/TLS, and IEEE 802.11i

Applications

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

Procurement Notes

Verify silicon revision level before procurement; this document applies to revision 3.x silicon and later (orderable part numbers ending in A or B). Confirm compatibility with existing designs using earlier silicon revisions by consulting the MPC8349E Hardware Specifications. Ensure power sequencing adheres to guidelines where core voltage rises to 90% of nominal value before I/O supplies reach 0.7 V.

Selection Notes

Select this component for applications requiring high-performance embedded processing with integrated networking and security features. Consider the 667 MHz maximum clock speed and support for both DDR1 and DDR2 SDRAM. Verify interface requirements against the available dual TSECs, dual PCI ports, and USB multi-port host capabilities.

Part Context

The MPC8349VVAGDB belongs to the MPC8349EA PowerQUICC II Pro family. It serves as a next-generation upgrade to the PowerQUICC II series, offering enhanced performance through the e300 core and increased integration of system logic for networking, storage, and general-purpose embedded applications.

Replacement Considerations

Consult the MPC8349E PowerQUICC II Pro Integrated Host Processor Hardware Specifications for details on earlier silicon revisions (revision 1.1 and prior). Verify functional equivalence if replacing units from older production batches.
