MPC8349EVVAJDB - PowerQUICC II Pro 533MHz SoC | NXP
MPN： MPC8349EVVAJDB ✓ 啟用中MPC8349EVVAJDB 概覽
A PowerQUICC II Pro integrated host processor is a class of embedded SoC that combines a high-performance PowerPC CPU core with dedicated communications peripherals, eliminating the need for an external MAC, security accelerator, or memory controller in routers, switches, and access equipment. Positioned within the hierarchy PowerPC -> embedded communications SoC -> PowerQUICC II Pro -> MPC8349E family, the part integrates the e300 core (an enhanced version of the classic PowerPC 603e core with 32 KB L1 instruction and data caches), the system interface unit (SIU), dual DDR memory controllers, and the QUICC Engine for protocol termination.
Key differentiating features include hardware-accelerated security (SEC 2.0+), a 32-bit DDR1/DDR2 memory controller supporting up to 1 GB of addressable memory, two 32-bit/33 MHz PCI interfaces, a 10/100/1000 Mb/s Ethernet MAC, USB 2.0 full-speed device/host, and flexible I/O voltages (1.8V, 2.5V, 3.3V). The 0.13 micron CMOS process keeps typical core power in the 1.5 to 2.5 W range, while the industrial-grade 0 to 105 C junction temperature range supports carrier-grade equipment deployments.
Typical applications include wired and wireless routing and switching, secure VPN gateways, industrial control, networked storage controllers, and PCI-based embedded designs. The dual-PCI interface allows simultaneous connection to a host CPU and a downstream device, simplifying system partitioning.
When designing with this part, allocate at least four PCB layers for power/ground integrity, follow the Freescale/NXP layout guide for DDR routing (length-matched, 50 ohm impedance), and use the SEC accelerator for AES/3DES/SHA to offload cryptographic work from the CPU.
This page synthesizes distributor pricing, drop-in family variants, and design notes that go beyond the manufacturer datasheet to accelerate evaluation and second-source decisions.

典型應用
MPC8349EVVAJDB 適用於 6 應用s: Enterprise Router / VPN Gateway, Wireless Access Controller, Network Attached Storage (NAS) Controller, Industrial Control / Factory Automation, PCI-Based Embedded Computing, Secure Communications Appliance.
Enterprise Router / VPN Gateway
The MPC8349EVVAJDB is a strong fit for enterprise routers and VPN gateways because it integrates the e300 PowerPC core, Gigabit Ethernet MAC, dual PCI, and hardware SEC on a single die. Hardware-accelerated AES/3DES/SHA allows IPsec and TLS tunnels to run at line rate without burdening the CPU, and the DDR1/DDR2 controller supports the memory bandwidth needed for routing tables and crypto contexts. The 672-LBGA package supports fanless industrial enclosures at 0-105 C.
推薦
Wireless Access Controller
The MPC8349EVVAJDB suits wireless access controllers and small-cell base stations thanks to its combination of Gigabit Ethernet for backhaul, dual PCI for expansion to DSP or radio cards, and SEC for authentication. The e300 core at 533 MHz handles management-plane traffic while offloading crypto to the SEC engine. The 0.13 micron process and 1.8/2.5/3.3 V I/O simplify integration with legacy radios and modern DSPs.
推薦
Network Attached Storage (NAS) Controller
NAS controllers and storage area networks benefit from the MPC8349EVVAJDB's PCI interfaces for connecting to SATA or Fibre Channel controllers, Gigabit Ethernet for network attachment, and DDR1/DDR2 memory support for caching. The hardware security engine offloads file-encryption workloads, while the e300 core handles filesystem, RAID, and network protocols. The 672-LBGA's high pincount exposes all required parallel interfaces.
推薦
Industrial Control / Factory Automation
For industrial control and factory automation, the MPC8349EVVAJDB delivers deterministic networking with its PCI interfaces for I/O cards, Gigabit Ethernet for SCADA connectivity, and SEC for secure device authentication. The 0-105 C junction temperature range supports cabinet and outdoor installations, while the 672-LBGA package enables compact carrier boards. Real-time operating systems (VxWorks, QNX) run natively on the e300 core.
推薦
PCI-Based Embedded Computing
The MPC8349EVVAJDB is widely used as a PCI host or device in embedded computing platforms. Its two PCI interfaces allow it to act as a bridge between an upstream x86 host and downstream DSP or FPGA cards, while the e300 core runs real-time control code and the SEC engine handles secure boot. The 672-LBGA package exposes all PCI signals cleanly for short, impedance-controlled board traces.
推薦
Secure Communications Appliance
For secure communications appliances (SSL gateways, IPsec concentrators, encrypted backhaul), the MPC8349EVVAJDB's hardware SEC engine accelerates AES/3DES/SHA/RSA/Kasumi at wire speed, while the e300 core manages sessions and routing. The 533 MHz clock is sufficient for dozens of tunnels at small packet sizes, and the DDR2 controller holds large security association tables. Industrial thermal rating supports outdoor or telco deployments.

設計說明
The 672-LBGA package requires a minimum 4-layer PCB stackup with dedicated power and ground planes to meet NXP's DDR signal-integrity recommendations. DDR traces must be length-matched within 25 mils and routed to 50 ohm single-ended impedance (100 ohm differential for clock/address). Allocate at least 2 oz copper for the ground plane under the BGA to reduce Vcore bounce. Follow the Freescale AN3369 layout guide for the DDR2 controller for production-grade designs.
At typical router workloads (e300 @ 533 MHz, DDR2 active, one GbE port active), the die dissipates approximately 1.5-2.5 W. With the LBGA package theta_JA around 12-15 C/W on a 4-layer board, the junction-to-ambient rise is roughly 25-40 C, well within the 105 C junction limit at 70 C ambient. For sealed enclosures with no airflow, derate by 10-15 C. Avoid placing the BGA directly above heatsink fins where convection is poor.
Do not bypass the SEC initialization sequence if your firmware uses hardware crypto - failing to initialize the SEC register map causes silent encryption faults. Always source the DDR2 termination voltage (1.8 V VTT) with a high-current LDO; sharing VTT with a general-purpose rail causes jitter and CRC errors. The two PCI interfaces share pins - configure pin muxing before binding drivers. Boot from flash with proper wait-state settings for the chosen NOR device.
