MPC8247VRPIEA 概要
A PowerQUICC II processor is a category of integrated communications processors that combine a PowerPC host core with a CPM co-processor for offloading networking and telecom tasks from the host CPU. Within the broader taxonomy, MPC8247VRPIEA sits as MPU (microprocessor unit) -> communications processor -> embedded processor -> semiconductor, where it is the cost-optimized member of the PowerQUICC II family for Ethernet-centric designs rather than the TDM-heavy MPC8250/60 family. The integrated CPM lets a single chip replace a CPU plus a separate network controller, reducing BOM cost and board area in routers, gateways, and access points.
Key features of the MPC8247VRPIEA include 16 KB instruction cache / 16 KB data cache, integrated MMU supporting 4 GB address space, 32-bit PCI 2.2 interface, USB 1.1 host/slave controller, two 10/100 Ethernet MACs with MII/RMII interfaces, four SCCs, two SMCs, and a SPI/I2C interface. The 516-pin PBGA package provides ample signal routing for the parallel external bus, PCI, and multiple serial channels.
The architecture pairs the G2_LE integer core with a CPM that runs independently, allowing DMA-driven serial protocol handling in hardware while the host executes the application stack. This separation is the hallmark of the PowerQUICC family and what differentiates MPC8247VRPIEA from simpler PowerPC G2 microprocessors that lack integrated communications peripherals.
Typical applications include small/medium enterprise routers, VPN/firewall gateways, wireless access points, residential gateways, industrial serial-to-Ethernet converters, and embedded networking appliances where PCI expansion and Ethernet MACs are required on a single device. The device has been widely adopted in long-lifecycle industrial designs.
When designing with the MPC8247VRPIEA, ensure the 2.5V and 3.3V rails are sequenced correctly and that the JTAG pins are accessible for boundary-scan debug. The NXP product page notes this part is in End-of-Life status, so new designs should evaluate the MPC8308 or MPC8313E successors or plan for last-time-buy sourcing.

主な用途
MPC8247VRPIEA の用途: 6 件s: SME Router Platform, VPN / Firewall Gateway, Wireless Access Point Controller, Industrial Serial-to-Ethernet Converter, Residential Gateway, Embedded Networking Appliance.
SME Router Platform
The MPC8247VRPIEA is purpose-built for small/medium enterprise routers where a single chip must terminate WAN Ethernet, run a routing stack, and provide PCI expansion for crypto accelerators. Its 300 MHz G2_LE core delivers 570 MIPS - sufficient to forward packets at wire speed on Fast Ethernet WAN ports while running an embedded Linux or VxWorks routing daemon. The integrated dual 10/100 Ethernet MACs drive one WAN and one LAN port without an external PHY controller, and the PCI 2.2 bus allows an add-in card for hardware encryption (e.g. IPSec offload) or a T1/E1 CSU/DSU. Compared with a CPU-plus-discrete-NIC architecture, the PowerQUICC II CPM offloads HDLC framing and DMA, freeing the host core for routing table lookups. Designers benefit from the long-lifecycle, proven PowerPC toolchain (Wind River, Green Hills, Linux 2.6 BSP) and the 516-PBGA's robust thermal performance for fanless SME router enclosures.
おすすめ
VPN / Firewall Gateway
The MPC8247VRPIEA is widely deployed in VPN/firewall gateways that need on-chip Ethernet plus PCI for hardware crypto cards. The integrated CPM handles packet DMA and HDLC framing while the G2_LE host executes the IPSec/IKE state machine and policy lookup. With 570 MIPS available at 300 MHz, the device can sustain ~80 Mbps of 3DES VPN throughput on a typical optimized build - well above T1/E1 WAN speeds typical of branch-office VPN appliances. The 32-bit PCI bus provides a clean path to a crypto accelerator card for AES/SSL offload, and the USB 1.1 host port can drive a 3G/LTE modem for cellular failover in branch-office deployments. Designers should pair the MPC8247VRPIEA with an external DDR memory controller (since the MPC8247 lacks integrated DDR) and provision adequate cooling for sealed gateway enclosures.
おすすめ
Wireless Access Point Controller
The MPC8247VRPIEA is a strong fit for managed wireless access points where it acts as the controller running the management stack and bridging Ethernet to a downstream 802.11 MAC over PCI. The integrated dual 10/100 Ethernet MACs drive the wired uplink and a daisy-chain port, while the PCI 2.2 interface hosts the WLAN card. The CPM offloads packet buffering, leaving the G2_LE core to run the WAP management firmware, RADIUS client, and 802.1X supplicant. Industrial temperature support (0 C to +105 C in the "VRPIEA" grade) suits outdoor or warehouse WAP deployments. Compared with low-end MIPS WAP processors, the PowerQUICC II delivers the MIPS headroom needed for enterprise-class WAP features without an external communications ASIC.
おすすめ
Industrial Serial-to-Ethernet Converter
The MPC8247VRPIEA's four SCCs plus two SMCs and a USB host make it an excellent platform for industrial serial-to-Ethernet converters that aggregate RS-232/422/485 lines and bridge them onto Ethernet. Each SCC supports HDLC and transparent synchronous modes, and the CPM can run multiple serial channels in hardware DMA without host CPU intervention. This frees the 300 MHz G2_LE core to run the Modbus/TCP, DNP3, or IEC 60870 protocol conversion stack. The PCI bus allows optional fieldbus cards (Profibus, CAN) for industrial automation gateways, and the 516-PBGA package provides sufficient thermal margin for factory-floor enclosures operating at +70 C ambient. Long-lifecycle NXP support and the proven PowerPC BSP ecosystem (Linux 2.6/3.x, VxWorks) make the MPC8247VRPIEA a popular choice for industrial automation OEMs.
おすすめ
Residential Gateway
The MPC8247VRPIEA integrates everything a residential gateway needs: dual 10/100 Ethernet for WAN/LAN, USB 1.1 host for printer or storage sharing, PCI for an optional 802.11 card, and four SCCs for HPNA or HomePlug control. The 300 MHz G2_LE host runs the broadband router stack (Linux 2.6 BSP with iptables/NAT) and the embedded web management UI. The PowerQUICC II architecture's CPM offloads packet forwarding, enabling wire-speed NAT at 100 Mbps WAN throughput - adequate for the majority of residential broadband tiers. Compared with newer SoCs, the MPC8247VRPIEA offers the longest NXP lifecycle window for ISPs that certify designs on decade-long deployment schedules.
おすすめ
Embedded Networking Appliance
The MPC8247VRPIEA is widely used in embedded networking appliances such as protocol converters, industrial print servers, and remote management controllers. Its combination of dual Ethernet, USB host/slave, four SCCs, and PCI gives appliance designers a single-chip platform on which to add a Linux or VxWorks networking stack. The G2_LE core at 300 MHz provides 570 MIPS, sufficient to run embedded web servers, SNMP agents, and modest TCP/UDP throughput. The integrated MMU supports full Linux/embedded OS virtualization, while the CPM's independent DMA engine keeps serial-channel latency low under load. The 516-PBGA (27x27 mm) package requires a 4-layer PCB minimum but is compatible with standard reflow profiles and high-volume SMT assembly.

- NXP-EOL but still has active distributor stock （vs MPC8247VRMIBA (266 MHz bin))
設計ノート
The MPC8247VRPIEA requires separate 2.5V (core) and 3.3V (I/O) rails. Per NXP design guidance, power sequencing should bring up the 2.5V core rail before or simultaneously with the 3.3V I/O rail, and a power-on-reset supervisor (e.g. NXP/TI TPS3808) must hold RESET for at least 1 ms after both rails are stable. Bulk decoupling: 22 uF tantalum + 0.1 uF ceramic per power pin pair is typical. Estimated: at 300 MHz the core consumes approximately 1.5W; at 266 MHz approximately 1.2W (label as estimate - not a datasheet figure).
The 516-PBGA (27x27) package has a 1.27 mm ball pitch and requires a 4-layer PCB minimum with continuous ground reference planes under the BGA footprint. Use 0.5 oz copper on outer layers and 1 oz on inner layers; escape routing on the top layer uses 4-mil traces between pads with microvia-in-pad (laser-drilled) recommended for fanout. Place SDRAM and the PCI bridge within 1 inch of the BGA to keep parallel-bus stub lengths below 1.5 inches.
The 516-PBGA package has a junction-to-ambient thermal resistance (theta_JA) of approximately 15 C/W on a 4-layer JEDEC test board. Estimated: at 1.5W dissipation and 70 C ambient, junction temperature rises to 92 C - below the 105 C maximum. For sealed enclosures with poor airflow, derate to 60 C ambient and confirm with a thermocouple on the top of the BGA. Adding thermal vias under the BGA and a 6-layer PCB reduces theta_JA to roughly 10 C/W.
Three pitfalls specific to the MPC8247VRPIEA: (1) do not confuse the MPC8247 (no TDM) with the MPC8250 (TDM-capable) - same package family but different silicon; (2) the 27x27 mm BGA package cannot be hand-reworked without specialized BGA rework equipment; (3) because the part is EOL, verify last-time-buy window dates with NXP and lock in supply before committing to a new design. Always check the NXP product page for the latest PCN before sourcing.
