MPC8347VVAJDB 概述
A PowerQUICC II Pro MPU (microprocessor unit) is a highly integrated system-on-chip (SoC) designed for embedded networking infrastructure. It sits in the hierarchy of networking processors: application processor -> communications processor -> PowerQUICC -> PowerQUICC II -> PowerQUICC II Pro. These devices combine one or more CPU cores with dedicated communications engine blocks (QUICC Engine), eliminating the need for external networking ASICs in mid-range routers, switches, and DSLAMs.
Key features include a 533MHz e300 core, 32KB L1 instruction cache and 32KB L1 data cache, dual DDR1/DDR2 memory controller up to 333MHz, 32-bit PCI 2.3 interface, 1Gbps Ethernet MAC, USB 2.0 Full-Speed, four UARTs, two I2C controllers, and an integrated security engine. The device is manufactured in a 0.13um CMOS process with 1.8V/2.5V/3.3V mixed-voltage I/O.
Typical applications include SOHO routers, xDSL line cards, industrial Ethernet gateways, network-attached storage (NAS) controllers, print server engines, and 3G/WiMAX base-station control plane processors. The integrated communications peripherals reduce BOM cost and PCB area versus discrete CPU-plus-ASIC designs.
When migrating to newer designs, engineers should note that the MPC8347E family is in end-of-life status per the NXP product page. The recommended replacement family is the PowerQUICC III / QorIQ P1020/P2020 for new designs, while existing designs can use the same-family MPC8347E variants (with security engine enabled) on the same 672-TBGA footprint as a drop-in upgrade.
This page synthesizes distributor availability, same-package drop-in alternatives (including the MPC8347E family and cross-brand Freescale/NXP pin-compatible MPNs), and practical design guidance not duplicated on DigiKey or Mouser product listings.

典型应用
MPC8347VVAJDB 适用于 6 应用s: SOHO Router / xDSL Gateway, Industrial Ethernet Gateway / Protocol Bridge, Network-Attached Storage (NAS) Controller, Print Server / Imaging Engine, 3G/WiMAX Base Station Control Plane, Telecom Line Card / DSLAM Controller.
SOHO Router / xDSL Gateway
The MPC8347VVAJDB fits SOHO router and xDSL gateway designs because its integrated QUICC Engine accelerates PPPoE, IP routing, and ATM/TDMA offload without external ASICs. At 533 MHz, the e300 core delivers around 600 Mbps IPv4 forwarding throughput, sufficient for combined NAT, firewall, and QoS on consumer broadband gateways. The on-chip GbE MAC connects directly to a PHY, while the PCI 2.3 link to an external 802.11a/b/g/n Wi-Fi mini-PCI card eliminates separate host processors. The DDR2 memory controller (up to 333 MHz) handles routing tables for typical SOHO / 4G-router workloads, and operating from 0C to +105C means the part tolerates the enclosed thermal environment of consumer Wi-Fi equipment without derating.
推荐
Industrial Ethernet Gateway / Protocol Bridge
The MPC8347VVAJDB is a natural fit for industrial Ethernet gateways that bridge Modbus/TCP, EtherNet/IP, PROFINET, and legacy fieldbuses because its QUICC Engine handles multi-protocol termination concurrently. 533 MHz CPU headroom runs Linux or VxWorks with a full TCP/IP stack and OPC-UA server, while the integrated GbE MAC and USB 2.0 host simplify integration with HMIs and external sensors. The 672-TBGA package lands on industrial SBC form-factors designed for fanless operation - the +105C junction rating tolerates sealed enclosures at 70C ambient with passive heatsinks.
推荐
Network-Attached Storage (NAS) Controller
The MPC8347VVAJDB is well-suited for entry-level NAS controllers because the 533 MHz e300 core sustains sequential SMB/NFS throughput over the GbE MAC, while DDR2 memory (up to 333 MHz with ECC) handles RAID write buffers. PCI 2.3 connects to SATA host controllers or 1 GbE NICs for multi-port expansion, and USB 2.0 connects to external backup drives. Power consumption at the 672-TBGA package level is contained enough for fanless NAS designs, and the security-disabled variant suffices for trusted enterprise deployments without requiring the E-prefix.
推荐
Print Server / Imaging Engine
Multi-function printer (MFP) controllers can use the MPC8347VVAJDB as the print server engine because it drives USB 2.0 device ports for scanner image transfer, handles onboard image processing at 533 MHz, and exposes PCI 2.3 to ASIC scanner engines. The DDR2 controller supports large page buffers for high-DPI A3 scans, while the GbE MAC handles common cloud-print protocols (Apple AirPrint, IPP, Mopria). The 672-TBGA's 0C to +105C envelope fits inside printer chassis where ambient reaches 60C with paper-feed motors active.
推荐
3G/WiMAX Base Station Control Plane
The MPC8347VVAJDB fits as the control-plane processor in picocell and femtocell base stations because the QUICC Engine manages ATM/AAL2 SAR and PPP termination while the e300 core runs Layer-3 protocols. 533 MHz is sufficient for small-cell signalling at hundreds of subscribers, and the dual UARTs connect to RF front-end ASICs and digital pre-distortion blocks. The 672-TBGA's industrial temperature grade handles outdoor picocell enclosures without active thermal management.
推荐
Telecom Line Card / DSLAM Controller
The MPC8347VVAJDB supports compact DSLAM and access-network line cards where its QUICC Engine accelerates AAL2 SAR, MLPPP bonding, and channelised T1/E1 framing without external framers. The 32-bit PCI bus hosts multi-channel DSP blades for voice CODECs, and the integrated GbE uplinks to access-aggregation switches. Software compatibility with the broader PowerQUICC II Pro family simplifies reuse of carrier-grade Linux distributions and existing OAM stacks.

设计说明
Estimated: at 533 MHz core clock and the typical 1.0V core voltage under full load, the MPC8347VVAJDB dissipates in the range of 2.5 W to 3.5 W (input data assumed). The 672-TBGA package with adequate internal/external copper ground planes plus a small heatsink (10 mm x 10 mm x 5 mm) is enough to keep the junction temperature below +105C under +70C ambient in fanless SOHO router enclosures. Place thermal vias on the BGA's central power-grid ball array and connect them to a copper ground plane on the bottom layer.
Use a 6-layer PCB stack-up with dedicated ground and 1.8V core planes. Route DDR2 signals with 50-ohm controlled impedance and length-match DQ lines within +/- 25 mils. Place DDR2 bypass 0.1 uF + 10 uF capacitors adjacent to the VDDQ pads. The QSGMII / GMII traces to the GbE PHY must be length-matched within 50 mils, ideally with guard traces above and below to isolate them from the PCI bus. The clock generator IC should be placed within 100 mils of the LX1/LX2 inputs to minimise skew.
Do NOT confuse MPC8347VVAJDB (no security engine) with MPC8347EVVAJFB (security engine present) when ordering - the lookalike suffixes are a common stocking error. Ensure boot-config pins are correctly pulled at HRESET release (using 4.7 kohm resistors to the correct GVDD rail), otherwise the system will hang in the legacy boot mode and never initialise DDR. Do not exceed 1.8V/2.5V/3.3V supply rails; the 0.13um CMOS core is sensitive to over-voltage damage during hot-reboot events.
Estimated: the GbE RGMII/GMII interface runs at 125 MHz, putting the signals in the 350 ps-edge-rate regime. Series-source termination of 22 ohms to 33 ohms on GMII transmit data lines is suggested to reduce ringing on the 5 cm-to-15 cm traces to the PHY. Use a separate 1.0V/1.8V PLL filter network around each PLL supply pin with a 2.2 uF + 0.01 uF LC pi-filter; inadequate filtering is the most common cause of timing-related system instability on PowerQUICC II Pro designs.
合规信息
RoHS compliant per the NXP product page and DigiKey listing. The -40C to +85C industrial-grade variants use a different order-code suffix (EIS/EIA) and should be selected if compliance to AEC-Q100 or similar automotive standards is required.
