MPC8347VRADDB - PowerQUICC II Pro SoC, 266MHz, 620-HBGA | NXP
料号： MPC8347VRADDB ⚠ 最后一次采购MPC8347VRADDB 概述
An embedded microprocessor / microprocessor unit (MPU) is a self-contained processing subsystem in which the CPU, memory controller, peripheral controllers, and I/O interfaces are integrated onto a single die. The MPC8347 sits at the upper tier of NXP's PowerQUICC II Pro family, targeting wired networking, industrial control, and secure communications designs where deterministic performance and rich I/O integration reduce system bill of materials.
Key features include a 266 MHz e300 core with 32 KB instruction and 32 KB data L1 caches, a 266 MHz 64-bit DDR1/DDR2 memory controller with ECC, a 32-bit/66 MHz PCI interface, a 1 Gbit/sec Ethernet MAC, USB 2.0 host/device, four UARTs, two I2C, dual SPI, and an integrated security engine (SEC 2.0) for IPSec, SSL/TLS, and 3DES/AES/SHA acceleration. Local bus and GPIO further expand peripheral options.
Technically, the device is fabricated in a 0.13 µm CMOS process and uses a 32-bit Power Architecture Book-E compliant core. It exposes a 60x bus interface, supports JTAG 1149.1 boundary scan, and provides hardware MMU with 16-entry TLB. The HBGA package provides the thermal dissipation needed for the device's typical 1.1 V core / 3.3 V I/O dual-supply operation.
Typical applications include industrial Ethernet switches and routers, secure VPN gateways, wireless base-station controllers, factory-automation controllers, and point-of-sale terminals. This part specifically (no security engine suffix in the order code per datasheet naming) suits designs that need the SoC I/O integration but rely on an external security coprocessor.
When designing in the MPC8347VRADDB, allocate generous PCB area for the 620-ball HBGA footprint, use a 6-8 layer stackup with dedicated power planes for the 1.1 V core and 3.3 V I/O rails, and follow NXP application note AN3889 for DDR2 layout and signal-integrity validation.

典型应用
MPC8347VRADDB 适用于 7 应用s: Industrial Ethernet Switch / Router, Secure VPN / Firewall Appliance, Industrial Automation Controller / PLC, Wireless Base Station Controller (Small Cell / BTS), Point-of-Sale (POS) Terminal / Retail Payment Device, Medical Imaging Front-End / Diagnostic Controller, Network-Attached Storage / NAS Controller.
Industrial Ethernet Switch / Router
The MPC8347VRADDB fits industrial managed Ethernet switches and routers because its integrated 1 GbE MAC, hardware acceleration for IPv4/IPv6 forwarding, and SEC 2.0 engine let designs handle wire-speed routing and IPSec/SSL/TLS termination without external coprocessors. Combined with its 266 MHz e300 core and 32-bit/66 MHz PCI expansion, the part serves as the network processing unit when paired with multi-port PHY switches via the MII/GMII interface. The HBGA package provides the thermal dissipation path required for continuous 0-105C operation in fanless enclosures, while DDR1/DDR2 with ECC keeps packet buffers reliable at high throughput.
推荐
Secure VPN / Firewall Appliance
The MPC8347VRADDB integrates the SEC 2.0 engine that offloads AES, 3DES, SHA-1/256, MD-5, and Kasumi in hardware - critical for VPN/firewall appliances that must sustain hundreds of Mbps of IPSec or SSL/TLS throughput at sub-millisecond latency. The 266 MHz e300 core runs the control-plane (routing/CLI policy engine) while the SEC engine executes data-plane crypto. The dual-rail 1.1 V core / 3.3 V I/O design lets designers split sensitive crypto-domain power planes from the I/O for EMC, and the 620-HBGA's 29x29 mm footprint leaves room on the PCB for additional Ethernet/PHY and TPM components typical of hardened security gateways.
推荐
Industrial Automation Controller / PLC
In industrial PLC and motion-control controllers, the MPC8347VRADDB's deterministic e300 core, real-time interrupt controller, and four-channel DMA give accurate task scheduling for 0-105C factory-floor operation. The dual SPI, two I2C, and four UARTs on the part handle dense sensor and actuator wiring without external bus expanders, while the PCI bridge and local-bus controller connect to motor-driver and A/D-D/A daughter cards used in servo loops. Built-in ECC on the DDR memory controller protects against single-bit upsets in noisy electrical environments characteristic of industrial plants.
推荐
Wireless Base Station Controller (Small Cell / BTS)
The MPC8347VRADDB's combination of 1 GbE MAC, PCI expansion (for baseband FPGA/DSP cards), USB 2.0 (for backhaul modem or diagnostics), and SEC 2.0 (for cipher acceleration on CPRI backhaul and management traffic) makes it a fit for small-cell base-station controllers in LTE/3GPP networks. The e300 core's integer performance supports the L2/L3 control-plane of the base station while hardware-assisted DMA reduces CPU loading on user-plane transfers. The wide 620-HBGA ball-grid exposes enough signal bandwidth for both Ethernet and PCI expansion.
推荐
Point-of-Sale (POS) Terminal / Retail Payment Device
MPC8347VRADDB serves as the central processor in POS terminals where PCI-PTS compliance requires hardware crypto (SEC 2.0 engine provides AES/SHA/3DES), and the integrated USB 2.0 host handles barcode scanners, customer displays, and PIN pad peripherals. The 1 GbE MAC connects to back-office payment networks, while the 32-bit PCI enables expandability for receipt printers and cash drawer controls. The 0-105C industrial temperature rating and lead-free HBGA package make the part deployable in unattended retail enclosures that may run continuously for years.
推荐
Medical Imaging Front-End / Diagnostic Controller
Medical imaging systems like ultrasound front-ends benefit from the MPC8347VRADDB's 32-bit/66 MHz PCI for high-resolution ADC data acquisition cards, plus the 1 GbE MAC for DICOM image transfer and the SEC engine for patient-data encryption. The 266 MHz core runs the imaging pipeline (beamforming, scan conversion) while DDR2 with ECC ensures data integrity for diagnostic-quality images. Operating across 0-105C and featuring a robust 620-HBGA package with ESD-aware I/O structures, the part is suitable for imaging subsystems complying with IEC 60601 design guidelines.
推荐
Network-Attached Storage / NAS Controller
The MPC8347VRADDB's 1 GbE MAC, DDR2 with ECC, and PCI expansion are well matched to entry/mid-range NAS controllers, where the SEC engine accelerates encrypted-disk operations (AES-XTS) and the e300 core runs the RAID stack and file-system services. The dual-rail 1.1 V/3.3 V design lets hardware teams isolate the memory subsystem from noisy disk-interface supplies, and the 620-HBGA provides thermal margin for the sustained workload of a multi-drive enclosure. The integrated USB 2.0 supports external backups or UPS status reporting.

设计说明
Estimated: the MPC8347VRADDB at 266 MHz dissipates approximately 1.5-2.0 W core power. The 620-HBGA junction-to-ambient thermal resistance is on the order of 15-20 C/W with a properly designed 6-8 layer PCB and via-in-pad thermal ball pattern. Use at least 4 thermal vias per 0.5 mm thermal-ball array in the center of the package, stitched through to inner copper pours, to keep Tj below 105 C in fanless industrial enclosures.
Estimated: allocate a 6-8 layer PCB stackup with dedicated ground and 1.1 V core planes plus a 3.3 V I/O plane. Follow NXP AN3889 for DDR2 trace length matching (within 50 mil on byte lanes), 100 ohm differential impedance for PCI/PCI-X, and 90 ohm for USB 2.0. All decoupling capacitors must be placed within 100 mil of their respective package pins, with 0.1 uF and 1 uF ceramic combinations per VDD ball group.
Do not apply power (1.1 V core or 3.3 V I/O) before the on-chip POR completes - hold RESET to logic-low for at least 32 warm-up oscillator cycles after the oscillator stabilizes. The DDR2 controller requires PLL lock before any DDR clock toggles; otherwise bus contention can latch the device into an undefined state. Also note that the 8347 part number's absence of a 'C' or 'E' suffix means the security engine is disabled in the SKU order code; verify the security-bootloader firmware path before assuming crypto acceleration is available.
合规信息
Per NXP product-page environmental data, the MPC8347VRADDB is supplied Pb-free and is RoHS/REACH compliant. Not AEC-Q100 qualified - this is an industrial SoC, not an automotive part. Halogen-free per JEDEC JS709.
