MPC8349EVVAJFB 概述
An integrated communications processor (often abbreviated as comms processor or SoC MPU) is a high-integration system-on-chip that combines a CPU core, memory controller, and multiple communications peripherals (Ethernet MAC, PCI, USB, UART, I2C, SPI) on a single die. In the broader taxonomy, the MPC8349E sits at the intersection of microprocessor (MPU), network processor, and embedded SoC: MPU -> communications processor -> PowerQUICC family -> PowerQUICC II Pro -> MPC83xx series -> integrated SoC. This consolidation lets a single chip replace a CPU plus a separate Ethernet controller, security accelerator, and bus bridge.
Key features of the MPC8349EVVAJFB include a 533 MHz e300 core with 32 KB L1 instruction cache and 32 KB L1 data cache, hardware cryptography (SEC 2.0) with random number generator, dual 10/100/1000 Mb Ethernet MACs, two PCI interfaces (one 32-bit/66 MHz, one 32-bit/33 MHz), DDR1/DDR2 SDRAM controller up to 266 MHz, USB 2.0 full/low speed interface, two DUART ports, I2C, SPI, and a local bus controller. The 672-LBGA package is supplied in a tray and operates from 0C to 105C junction temperature with core voltages around 1.14V to 1.26V (per published specifications). It is RoHS compliant and uses a lead-free terminal finish.
Architecturally, the e300 core is a superset of the classic PowerPC 603e with deeper pipelining and improved MMU, while the system interface unit (SIU) and communications engine handle the IO and memory fabric. The integrated SEC 2.0 off-loads bulk cryptography (DES, 3DES, AES, SHA, MD5, RSA) at line rate, which is critical for VPN, SSL/TLS, and IPsec gateways. DDR1/DDR2 support up to 266 MHz data rate allows memory subsystems sized to multi-megabyte packet buffers.
Typical applications include industrial routers and secure gateways, DSLAM and PON line cards, networked printers and multifunction controllers, industrial automation controllers with Ethernet connectivity, IPsec/SSL VPN concentrators, and embedded networking appliances requiring integrated cryptography. The 533 MHz speed grade and dual GbE make it suitable for line-rate VPN termination at modest packet sizes. A specific design consideration is thermal management at high activity; the TBGA-672 package exposes a thermal pad that must be soldered to a sufficient copper pour (typically four-layer PCB with thermal vias) to keep junction temperature inside the 0C-105C operating range.

典型应用
MPC8349EVVAJFB 适用于 6 应用s: Industrial Secure Router / VPN Gateway, DSLAM / PON Line Card Controller, Networked Multifunction Printer Controller, Industrial Automation Controller with Ethernet, IPsec / SSL VPN Concentrator, Embedded Networking Appliance (Linux-based).
Industrial Secure Router / VPN Gateway
The MPC8349EVVAJFB fits industrial secure routers because its integrated SEC 2.0 engine performs DES/3DES/AES/SHA/RSA at line rate, off-loading IPsec and SSL/TLS from the 533 MHz e300 core. The single GbE MAC and dual PCI allow a WAN uplink plus expansion cards for cellular or fiber modems. Compared with a discrete CPU plus external crypto chip, this SoC cuts BOM and board area while keeping thermal rise manageable in a sealed enclosure.
推荐
DSLAM / PON Line Card Controller
The MPC8349EVVAJFB's DDR1/DDR2 controller up to 266 MHz, dual PCI (one 66 MHz, one 33 MHz), and GbE MAC suit DSLAM or PON line-card designs that need a fast host CPU plus high-throughput interconnect to PHY ASICs. The e300 core at 533 MHz handles ATM/Ethernet segmentation, IGMP, and queue management, while the second PCI can host a downstream switch fabric. The 672-TBGA 35x35 mm footprint allows dense line-card layouts.
推荐
Networked Multifunction Printer Controller
In networked printers and MFPs, the MPC8349EVVAJFB provides the embedded host CPU plus GbE networking and USB 2.0 for direct-print and scan-to-host. The local bus controller connects NAND/NOR flash and the engine ASIC, while DUART and I2C drive the operator panel. Hardware SEC 2.0 secures the embedded web admin interface. The 0C-105C range covers office environments without needing industrial-grade parts.
推荐
Industrial Automation Controller with Ethernet
Industrial automation controllers benefit from the MPC8349EVVAJFB's deterministic PCI bus for motion or IO cards, plus GbE for plant-network connectivity. The e300 core runs Linux or VxWorks for soft-PLC and HMI workloads. DDR1/DDR2 with ECC ensures reliable operation in electrically noisy factory environments. Designers should heatsink the TBGA-672 properly to keep junction temperature below 105C in sealed cabinets.
推荐
IPsec / SSL VPN Concentrator
The MPC8349EVVAJFB's SEC 2.0 engine performs bulk IPsec ESP and SSL/TLS record processing at multi-hundred-Mbps line rates. Combined with the 533 MHz e300 core handling IKE key exchange and routing-table updates, the SoC can terminate dozens of VPN tunnels per device. The single GbE MAC faces the WAN; the second PCI hosts a crypto co-processor or additional Ethernet ports. This is the canonical target use case for the MPC8349E family.
推荐
Embedded Networking Appliance (Linux-based)
Embedded Linux networking appliances (firewalls, NAS, intrusion-detection sensors) leverage the MPC8349EVVAJFB's MMU-enabled e300 core, DDR1/DDR2 controller with ECC, and Gigabit Ethernet. The dual PCI allows expansion cards for wireless radios or RAID controllers. The local bus supports boot NOR flash plus status LEDs. Compared with x86 designs, this SoC draws far less power and produces less heat, simplifying fan-less enclosures.

设计说明
The 672-LBGA (35x35 mm) package relies on the die-attached thermal pad to conduct heat from the e300 core. Use a four-layer PCB with at least 1 oz copper on inner and outer layers and an array of thermal vias (0.3 mm pitch, 0.5 mm drill) directly under the package thermal pad. Estimated: at 533 MHz full activity with core voltage 1.2V and a typical application power dissipation of 4-5W, junction-to-ambient thermal resistance must stay below 20 C/W to keep Tj under 105C at 25C ambient. Without a thermal pad soldered to the copper pour, junction temperature can exceed limits within seconds.
Power-supply decoupling is critical for an e300 PowerPC core. Place a 1 uF ceramic decoupling capacitor within 5 mm of each VDD/VSS pair on the top layer, and add bulk 10 uF tantalum or polymer capacitors near the package. The 1.14-1.26 V core rail must ramp monotonically under the sequencing requirement described in the NXP datasheet; failure to meet sequencing can latch-up the part. Use a supervisory circuit or PMIC with proper power-good signalling.
Route DDR1/DDR2 signals as matched-length pairs with controlled impedance (50 ohm single-ended, 100 ohm differential for clocks). Keep trace lengths matched within +/- 25 mil for byte lanes to avoid setup/hold violations at 266 MHz. The MPC8349E reference design in the NXP hardware specifications manual shows a 6-layer stack-up; staying close to that stack-up simplifies timing closure. Do not route PCI or Ethernet signals across split ground planes.
Do not assume the boot ROM configuration pins map directly between MPC8349E and MPC8347E - the SEC 2.0 register base differs and a bootloader copy-pasted from an MPC8347 reference design will not initialize SEC. Use the U-Boot or BDI configuration file specific to the MPC8349E Rev 2 silicon. Also note the JTAG TRST pin must be pulled low per the IEEE 1149.1 specification; leaving it floating causes debug-session failures.
