MPC8247CVRMIBA 概要
A PowerQUICC II microprocessor is a member of the broader Power Architecture microprocessor family (MPC8xx → MPC82xx) and serves as an integrated communications processor (often classed as an MPU/SoC hybrid). Its role in the system hierarchy is to combine a general-purpose CPU core, memory controller, peripheral bridges, and on-chip networking engines, reducing BOM cost in routers, gateways, and embedded control designs. The MPC82xx line evolved from the earlier MPC860/MPC850 PowerQUICC I family, adding higher integration including Fast Ethernet, USB, and richer CPM protocols.
Key features include a 266 MHz G2_LE core, on-chip L1 caches (16 KB instruction, 16 KB data), an integrated SDRAM controller, PCI 2.2 interface (32-bit, up to 66 MHz), USB 1.1 full/low-speed host plus device, two fast Ethernet MACs (10/100 Mbit/s via CPM) with MII/RMII, and a comprehensive set of serial interfaces (FCC, SMC, SPI, I2C, UART) routed through the CPM. The integrated peripheral set eliminates the need for external bridges in small-to-medium routers.
The MPC8247 implements 32-bit PowerPC architecture with memory management units supporting real-time operating systems such as VxWorks, Linux, and Integrity. The CPM offloads DMA-driven protocol processing from the core, improving throughput in firewall, VPN, and access-point workloads while keeping CPU utilization low.
Typical applications include SME routers, residential gateways, VPN/firewall appliances, wireless access points, industrial serial-protocol converters, and embedded control for printing/scanning. The -40C to +105C industrial temperature range also suits outdoor and industrial gateway deployments.
When designing with the MPC8247, ensure your PCB layout respects the 27x27 mm PBGA landing pattern and provides adequate BGA thermal vias. The CPM requires careful pin-mux planning since FCC/SMC functions share package pins. For new designs consider the MPC8313E or P1020 as modern PowerQUICC II successors with integrated Gigabit Ethernet.

主な用途
MPC8247CVRMIBA の用途: 7 件s: SME Router and Firewall, Wireless Access Point, VPN and Security Appliance, Industrial Serial Protocol Gateway, Residential Gateway / SOHO Router, Print and Imaging Controller, Embedded Network Appliance Controller.
SME Router and Firewall
The MPC8247CVRMIBA integrates two 10/100 Ethernet MACs via the CPM, a 32-bit/66 MHz PCI 2.2 bridge, and a 266 MHz G2_LE core in a single chip, making it well suited to small and medium enterprise routers and firewall platforms. The CPM offloads packet forwarding and DMA from the CPU, allowing the G2_LE core to run the routing/filtering software stack without throughput bottlenecks. Power architecture peripherals (FCC/SMC) accelerate serial I/O for legacy WAN interfaces. Verified design references include NXP's PowerQUICC II evaluation boards used as reference designs for VPN/firewall appliances.
おすすめ
Wireless Access Point
The MPC8247CVRMIBA is used as the host controller in wireless access points, where the integrated CPM provides Ethernet MACs to interface with the radio MAC, the PCI bus connects the wireless chipset, and the USB port supports management or peripheral stacks. The 266 MHz PowerPC G2_LE core runs Linux or VxWorks with full networking stacks, while the CPM handles real-time packet DMA. Industrial temperature grade -40C to +105C supports outdoor and enterprise AP deployments. NXP provides reference designs for 802.11b/g access points based on PowerQUICC II MPUs.
おすすめ
VPN and Security Appliance
The PowerPC G2_LE core of the MPC8247CVRMIBA executes IPsec/SSL VPN stacks on Linux, while the integrated CPM accelerates bulk encryption data movement through dedicated DMA channels, offloading the CPU. Two 10/100 Ethernet MACs expose WAN and LAN ports directly, eliminating external PHY bridges for cost-optimized VPN routers and SMB firewalls. The hardware MMU and 32-bit address space support full-fledged OS environments, and the -40C to +105C temperature range suits industrial deployments. Reference NXP hardware manuals describe how to map encryption engines to CPM DMA channels.
おすすめ
Industrial Serial Protocol Gateway
The MPC8247CVRMIBA's CPM exposes multiple FCC and SMC channels that can be configured as UART, SPI, I2C, or HDLC serial interfaces, making this MPU ideal for industrial gateways bridging field-bus protocols to Ethernet. The PowerPC core runs protocol-conversion software while the integrated PCI 2.2 bus connects expansion peripheral cards for additional serial channels. The -40C to +105C industrial temperature grade supports factory floor and outdoor installations. NXP application notes describe PowerQUICC II usage in PROFIBUS-to-Ethernet gateways.
おすすめ
Residential Gateway / SOHO Router
The MPC8247CVRMIBA supports SOHO and residential gateway designs where cost is critical and integrated peripherals reduce total BOM. Two integrated 10/100 Ethernet MACs drive WAN and LAN ports directly, PCI 2.2 supports an optional Wi-Fi card, and the USB port supports external storage or printer sharing. The 266 MHz G2_LE core executes OpenWrt or vendor router firmware stacks comfortably. The CPM's hardware packet acceleration handles typical home broadband throughput without software bottlenecks.
おすすめ
Print and Imaging Controller
The integrated peripheral set of the MPC8247CVRMIBA - PCI, USB 1.1, dual Ethernet, and the CPM-driven serial channels - makes this MPU a good fit for networked multifunction printer, scanner, and copier controllers. The PowerPC G2_LE core runs the device firmware and image processing software, while the CPM drives DMA to the image scanner and print engine. The 516-PBGA industrial-temperature package supports embedded printer controller boards in commercial-grade equipment.
おすすめ
Embedded Network Appliance Controller
The MPC8247CVRMIBA serves as the main processor in compact network appliances such as load balancers, protocol converters, and remote access servers. The integrated peripheral set including two Ethernet MACs, USB, PCI, and multiple serial channels means a small footprint appliance can use the MPC8247 as a single-chip controller without external bridges. The integrated memory controller supports SDRAM up to 256 MB for OS and application storage. NXP reference designs for thin client and terminal servers are based on PowerQUICC II MPUs.

設計ノート
The 516-PBGA 27x27 mm footprint of the MPC8247CVRMIBA requires dense PCB routing: at least 6 routing layers with microvias are recommended. BGA pads should use NSMD (Non-Solder Mask Defined) geometry for high-assembly yield. Per IPC-7352 and NXP application notes, escape routing in the inner row should follow dog-bone or via-in-pad fanout patterns, with a minimum 0.4 mm pitch matched to typical BGA escape rules. Provide solid GND planes beneath the BGA and stitch vias around the perimeter for high-speed signal integrity.
Estimated: at 266 MHz core frequency with 1.5 V core supply and industrial temperature operation, typical core power is approximately 1.0-1.5 W. The PBGA package requires thermal vias under the die and thermal land pad to keep junction temperature below 105C. Use at least 4x4 thermal via array (0.3 mm diameter) directly under the BGA thermal pad to the inner GND plane. In enclosed industrial enclosures, additional heat-spreading via copper may be needed to meet thermal margins.
Do not confuse the MPC8247 with the MPC8250 - while both share the PowerQUICC II family, they use different packages (516-PBGA vs 480-TBGA) and require different PCB layouts. The CPM pin-multiplexed peripherals (FCC/SMC) are configured via software registers; USB differential pair routing must follow 90-ohm impedance rules and length matching within 150 mils per USB 1.1 high-speed layout guidelines. JTAG pins must be brought out to a header for boundary-scan testability during manufacturing.
Estimated: the MPC8247CVRMIBA requires a 1.5 V core supply (typical 500-800 mA at 266 MHz) and a 3.3 V I/O supply (typical 200-400 mA). Use low-noise LDO regulators for the 1.5 V core, and add a 22 uF decoupling capacitor within 5 mm of each VDD/VSS pair. Per NXP hardware specifications, hold all power rails within +/-5% tolerance; power sequencing requires 3.3 V to ramp before 1.5 V to prevent latch-up. RTC backup voltage (if used) should come from a separate coin cell.
Maintain differential impedance matching (100-ohm +/-10%) on Ethernet MII/RMII pairs. Per NXP PowerQUICC II reference schematics, keep the PCI bus traces within 4 inches and matched to 50-ohm impedance, with 22-33 ohm series termination. Memory address and data traces should be length-matched within +/-50 mils to prevent timing violations at the SDRAM controller. Reference the NXP AN-2287 application note for detailed layout recommendations.
