MPC8349EZUAJDB - 533MHz PowerQUICC II Pro SoC | NXP | Embedded
MPN: MPC8349EZUAJDB ✗ End of LifeMPC8349EZUAJDB Overview
What is a PowerQUICC II Pro SoC? It is a system-on-chip family from NXP (originally Freescale) that combines a PowerPC processor core with integrated communications peripherals. The PowerQUICC II Pro line extends the earlier PowerQUICC II architecture with higher core frequencies, DDR memory support, and enhanced security, sitting in the taxonomy hierarchy of communications processors > embedded SoC > integrated circuit.
Key features include 533 MHz core frequency, 32 KB L1 instruction and data caches, a unified internal bus architecture, hardware encryption acceleration, and flexible I/O including two PCI controllers, one Gigabit Ethernet MAC, USB 2.0 full-speed support, and dual UARTs. The device supports DDR1/DDR2 SDRAM with ECC for reliable memory subsystems.
Architecturally, the MPC8349E employs a Harvard-style L1 cache, a coherent system bus, and a dedicated peripheral bus that arbitrates access to the integrated peripherals. The SEC block accelerates DES, 3DES, AES, and public-key algorithms, offloading cryptography from the main CPU. The 533 MHz speed grade (denoted by the JDB suffix code segment) is the mid-tier within the MPC8349E family.
Typical applications include industrial control routers, secure VPN gateways, industrial Ethernet switches, networked printers, and telecom edge equipment requiring integrated Gigabit Ethernet and hardware cryptography. The combination of dual PCI and DDR2 makes it well-suited for legacy peripheral migration in industrial designs.
When designing with the MPC8349E, allocate at least four PCB layers for the TBGA break-out, follow NXP's AN-2807 thermal and decoupling guidance, and validate DDR2 read/write leveling with the supplied hardware specifications document. Note that the MPC8349E family is approaching end-of-life - confirm longevity with NXP before long-lifecycle deployments.

Typical Applications
MPC8349EZUAJDB is suitable for 6 applications: Industrial VPN Gateway, Secure Network Attached Storage, Industrial Ethernet Switch, Telecom Edge Equipment, Networked Multifunction Printer, Industrial Control Router.
Industrial VPN Gateway
The MPC8349EZUAJDB suits industrial VPN gateways because the integrated SEC engine accelerates DES, 3DES, AES, RSA, and ECC offloading IPsec throughput from the e300 core. The 533 MHz speed grade sustains wire-speed encryption on Gigabit Ethernet links. With DDR2 and dual PCI for legacy expansion, the SoC integrates the full router datapath on one chip. Reference NXP application note AN-2807 for PCB layout and NXP Linux BSP for software bring-up.
Recommended
Secure Network Attached Storage
For network attached storage appliances, the MPC8349EZUAJDB provides 533 MHz of PowerPC processing, DDR2 with ECC for filesystem integrity, and dual PCI for SAS or SATA controller cards. The SEC block accelerates AES-256 disk encryption with minimal CPU overhead. The 672-ball TBGA package allows compact mainboards. The NRND status means long-term deployments should plan a migration to a Layerscape successor.
Recommended
Industrial Ethernet Switch
The MPC8349EZUAJDB is well-matched to managed industrial Ethernet switches because of its Gigabit Ethernet MAC, dual PCI for PHY or switching ASIC expansion, and hardware crypto for MACsec or 802.1X authentication. The 533 MHz core handles Layer 3 routing and ACL processing. DDR2 ECC memory ensures reliable operation in harsh industrial environments. The wide 0 to 105C temperature grade supports cabinet-mount deployments.
Recommended
Telecom Edge Equipment
Telecom edge equipment including small-cell controllers and remote management cards benefit from the MPC8349EZUAJDB's combination of Gigabit Ethernet, PCI expansion, USB, and hardware security. The 533 MHz core is sufficient for protocol termination and OAM processing. DDR2 with ECC provides reliable memory for carrier-grade deployments. The integrated SEC block accelerates authentication and key exchange.
Recommended
Networked Multifunction Printer
Networked multifunction printers use the MPC8349EZUAJDB to handle Ethernet connectivity, scan-to-email encryption, and job queuing. The SEC engine offloads TLS handshake processing. The dual PCI buses support scanner and engine controller cards. The 533 MHz core sustains concurrent I/O streams without queueing bottlenecks. The 672-ball TBGA package enables slim mainboard designs inside the printer chassis.
Recommended
Industrial Control Router
Industrial control routers rely on the MPC8349EZUAJDB for deterministic Gigabit Ethernet forwarding, VPN termination, and protocol translation between fieldbus and IP networks. The integrated SEC block handles IPsec and TLS for secure remote access. The 0 to 105C temperature range supports cabinet-mount installations without active cooling. Dual PCI enables legacy industrial card integration.

Design Notes
Estimated: the 672-ball TBGA at 35x35 mm with 0.8 mm pitch requires at least a 6-layer PCB with 1 oz copper for power and 0.5 oz for signal layers. Microvia-on-pad or via-in-pad is mandatory to break out the inner rows of balls. Maintain a continuous reference plane under the BGA to control the impedance of the DDR2 bus at 267 MHz. Follow NXP application note AN-2807 for the recommended stack-up and decoupling scheme.
Estimated: at 533 MHz the MPC8349EZUAJDB core dissipates approximately 1.5 W typical and 2.5 W worst-case with full peripheral utilization. The 672-ball TBGA thermal resistance theta_JA is on the order of 12 C/W with 6-layer PCB, so a heatsink is generally unnecessary for typical industrial deployments but is recommended when DDR2 and SEC run concurrently at elevated ambient. Provide copper pours under the die area for heat spreading.
Always configure DDR2 read/write leveling during boot, otherwise the bus will fail to calibrate and the system will hang at U-Boot or fail to enumerate memory. Confirm the SEC engine is enabled in the RCW (Reset Configuration Word) before relying on hardware crypto APIs. Plan for the NRND status by evaluating the Layerscape LS1021A or T2080 as long-lifecycle successors in new designs.
