MPC8349EVVAGDB 概述
An MPU (microprocessor unit) is the central processing unit of an embedded system. In the SoC taxonomy MPU becomes a sub-category when major peripherals are integrated on-die (SoC -> communications processor -> PowerQUICC -> MPC83xx -> MPC8349E). The e300 core implements the PowerPC instruction set with MMU and signal-processing extensions, making the MPC8349E suitable for routing, switching, and protocol conversion workloads that demand deterministic throughput rather than raw MHz.
Key features include hardware-accelerated SEC for DES/3DES/AES/SHA, dual 10/100/1000 Ethernet MACs, USB 2.0 full/low-speed, two PCI 2.3 controllers (one 64-bit capable), DDR1/DDR2 memory controller up to 333 MHz data rate, and integrated PHYs. The TBGA package is lead-free (no Pb) and rated for industrial ambient operation, supporting fan-less chassis designs in telco and industrial networking.
The 0.13-micron CMOS implementation embeds CPM (Communications Processor Module) alongside the e300 core, offloading serial protocols, ATM, HDLC, and Ethernet traffic from the host CPU. The SEC engine accelerates bulk cryptographic operations without burdening the e300 core, enabling line-rate IPsec and SSL termination at GbE speeds.
Typical applications include industrial routers and switches, secure VPN gateways, wireless base-station control, factory automation controllers, network-attached storage (NAS) controllers, and PCI-based embedded compute cards. Industrial-grade temperature range and integrated peripherals eliminate the need for external co-processors in mid-range networking equipment.
When designing with this device, allocate sufficient PCB area for the 35x35 mm TBGA footprint and provide at least 4-layer routing with dedicated power planes for the 1.8V core and 2.5V/3.3V I/O rails. The MPC8349E is approaching end-of-life status per the manufacturer's product page; verify long-term supply before committing to new designs and consider the QorIQ successors for greenfield projects.
This page synthesizes distributor pricing, package- and footprint-matched drop-in variants from the MPC83xx family, and practical thermal/PCB design notes not found in the standalone datasheet.

典型应用
MPC8349EVVAGDB 适用于 7 应用s: Industrial Secure Router / VPN Gateway, Network-Attached Storage (NAS) Controller, PCI-Based Embedded Compute Card, Wireless Base-Station Controller, Factory Automation / PLC Controller, Secure Network Print Server / Imaging Appliance, Telecom Line Card / Access Multiplexer.
Industrial Secure Router / VPN Gateway
The MPC8349EVVAGDB is purpose-built for industrial secure routers and VPN gateways. Its hardware-accelerated Security Engine (SEC) performs DES/3DES/AES/SHA at line rate, allowing the e300 core at 400 MHz to handle routing/forwarding tables while SEC offloads IPsec/SSL encryption. Dual Gigabit Ethernet MACs enable WAN + LAN segmentation in a single device, and DDR2 support at 333 MHz sustains firewall state tables without external memory. The 672-TBGA footprint fits 1U appliance chassis and the 0-105C junction range supports fan-less industrial enclosures. Alternative K-screened (KMPC8349) variants cover extended-temperature sites.
推荐
Network-Attached Storage (NAS) Controller
In NAS controllers the MPC8349EVVAGDB acts as the main storage processor, with its e300 core running a lightweight NAS OS (Linux/uClinux) and its dual GbE MACs providing redundant network paths. The integrated DDR1/DDR2 controller with ECC maintains data integrity for cached file operations, and the dual PCI 2.3 controllers host SATA or SAS controller chips for disk shelves. Hardware SEC is optional (AES-NI-like) for encrypted volumes. Compared with general-purpose SoCs, the 672-TBGA package and 0-105C range fit rack-mounted NAS chassis where reliability matters more than GHz.
推荐
PCI-Based Embedded Compute Card
The MPC8349EVVAGDB's dual PCI 2.3 controllers (one 64-bit capable) make it ideal as a host CPU on PCI/PCI-X add-in cards used in telecom blades and industrial PCs. The host PCI bus connects to the backplane, while the secondary PCI drives onboard co-processors, FPGAs, or additional I/O. With 400 MHz e300 plus CPM offload, the card handles protocol conversion, HDLC, or ATM termination. The 672-TBGA package and 1.8V/2.5V/3.3V mixed I/O simplify interfacing with legacy 3.3V peripherals while keeping core power low.
推荐
Wireless Base-Station Controller
In wireless base-station controllers, the MPC8349EVVAGDB performs baseband control, O&M messaging, and backhaul encryption. Its Security Engine accelerates the AES and SHA operations used in 3GPP authentication (AKA) and IPsec backhaul. The two GbE MACs split control-plane and user-plane traffic, while the dual PCI hosts baseband DSP cards. Industrial 0-105C operation and the robust 672-TBGA package meet the MTBF and thermal requirements of outdoor cabinet and tower-top equipment. Migrating from PowerQUICC II to QorIQ is a natural evolution path.
推荐
Factory Automation / PLC Controller
For factory automation and PLC controllers the MPC8349EVVAGDB provides deterministic serial protocol processing (EtherCAT, Modbus, Profibus via CPM offload), deterministic Ethernet (via dual MAC), and a secure control plane (via SEC). The e300 core runs the real-time OS (RTOS) while the CPM handles time-critical fieldbus traffic. Industrial temperature screening (0-105C) and the 672-TBGA package fit DIN-rail mounted chassis with conductive cooling. Compared with newer Cortex-A SoCs, the MPC8349E offers better long-term availability for 10-15 year factory lifecycles.
推荐
Secure Network Print Server / Imaging Appliance
Embedded print servers and imaging appliances use the MPC8349EVVAGDB to drive high-speed Gigabit network interfaces, secure IP printing (IPsec/SSL), and on-board image-processing co-processors via the dual PCI bus. The DDR2 controller supports the bandwidth-hungry image pipeline, while the SEC engine authenticates print jobs and protects confidential documents. The 672-TBGA footprint and 0-105C operation suit the inside-floor office-printer chassis. The PowerQUICC II Pro family has a long installed base in imaging products, with mature Linux/uClinux BSPs available.
推荐
Telecom Line Card / Access Multiplexer
Access multiplexers and DSLAM/PON line cards deploy the MPC8349EVVAGDB as the central processor because of its CPM offload (TDM, HDLC, ATM), dual GbE uplinks, and integrated SEC for encrypted subscriber traffic. The 672-TBGA is a familiar footprint in telecom line-card designs, and the industrial temperature grade supports outdoor DSLAM cabinets. Two PCI controllers enable modular expansion to multiple subscriber ports via line-interface daughter cards. Long-life-cycle support has historically made PowerQUICC II Pro the default choice for telecom OEMs.

设计说明
The 672-TBGA package has a relatively high theta-JA; at full DDR2 + dual GbE + SEC operation the e300 core can dissipate 2-3W. Estimate: a 100x100 mm 4-layer PCB with a continuous ground plane typically yields theta-JA around 12-15 C/W, which keeps the junction rise below 50C at 2.5W - within the 105C limit. For sealed industrial enclosures, add a thermal pad soldered to the package center balls or a small aluminum heatsink with thermal interface material. Always measure with a thermocouple on the actual PCB before finalizing enclosure design.
Use a minimum 6-layer stack-up with dedicated 1.8V core and 2.5V/3.3V I/O planes; place at least 4-6 decoupling capacitors (0.1uF + 10uF bulk) within 5 mm of each power pin. The 672-TBGA uses a 27x27 ball grid with 1.27 mm pitch; via-in-pad with filled-and-capped vias is recommended for inner-row balls to route out cleanly. Match DDR2 trace lengths within 50 mil and maintain 100-ohm differential impedance for GbE. Reference the NXP MPC8349E hardware-design checklist before tape-out.
Do not assume the SEC engine is enabled on all MPC8349 sub-variants - the "E" prefix denotes SEC-enabled; the "C" or no-prefix variants have SEC disabled and the SEC registers are non-functional. Likewise, do not confuse the 400 MHz MPC8349E (this part) with the 528 MHz MPC8349EZUAJD or the GbE-less MPC8347E - the 672-TBGA footprint is shared but peripheral availability differs. Always verify the full ordering code against the NXP datasheet ordering information table before PCB assembly.
