MPC8343CZQADDB

Overview

The MPC8343CZQADDB is a PowerQUICC II Pro integrated communications processor based on the e300 system-on-chip architecture. It features a 32-bit high-performance superscalar core operating at 266 MHz, delivering 1260 MIPS. The device integrates DDR/DDR2 memory controllers with ECC support, dual PCI interfaces, dual Gigabit Ethernet MACs, and two high-speed USB controllers. It includes an embedded security engine supporting standard encryption algorithms and IEEE 802.11i compliance. The component utilizes a lead-free plastic BGA-620 package measuring 29 x 29 mm with a 1 mm pitch.

Feature Summary

• Integrated security engine providing hardware acceleration for DES, 3DES, AES, MD5, SHA-1, and ARC-4 algorithms alongside a public key accelerator.
• Dual Gigabit Ethernet controllers combined with dual PCI interfaces to facilitate high-throughput network routing and switching operations.
• e300 core architecture offering enhanced L1 cache performance and full software compatibility with legacy 603e-based products.

Applications

• Ethernet routers and switches
• Wireless LAN (WLAN) devices
• Network storage systems

Procurement Notes

Verify the specific suffix configuration against official NXP documentation to ensure correct pinout and voltage requirements. Confirm RoHS compliance status as manufacturing revisions may vary. Check for end-of-life notifications or obsolescence warnings prior to procurement planning. Ensure supply chain sources provide valid traceability for this discontinued semiconductor component.

Selection Notes

Select this processor for applications requiring a balance of networking throughput and integrated security processing within a compact footprint. The e300 core ensures migration paths from older PowerQUICC designs while adding DDR2 support. Evaluate thermal dissipation requirements for the BGA-620 package in enclosed industrial enclosures.

Part Context

This component belongs to the PowerQUICC II Pro family, representing an evolution of the widely adopted PowerQUICC II series. It serves as a host processor for communication infrastructure, bridging the gap between general-purpose computing and specialized network control tasks through its highly integrated peripheral set.

Replacement Considerations

Consult official cross-reference lists for functional equivalents such as the MPC8347E or MPC8349E series. Verify that substitute parts maintain compatible pinouts and software environments before implementation.
