MPC8247ZQMIBA 概要
What is a PowerQUICC II processor? A PowerQUICC II is an integrated communications processor family from NXP (formerly Freescale) that combines a PowerPC core with a separate CPM coprocessor. The CPM offloads communications tasks such as Ethernet MAC, ATM, HDLC/SDLC, and USB handling from the main CPU, enabling high I/O throughput without burdening the core. The family occupies a tier above simple microcontrollers but below full application processors, typically deployed in mid-range networking infrastructure where deterministic peripheral performance is required.
Key specifications of the MPC8247ZQMIBA include a 266 MHz core frequency, 1.5V core voltage, 3.3V I/O voltage, 0.13 micrometer HiP7 process technology, and a 516-pin plastic BGA package. The device supports 32-bit addressing, integrates dual 10/100 Ethernet MACs through the CPM, two PCI interfaces, memory controller for SDRAM and ROM/Flash, and a USB 1.1 interface. The ZQMIBA speed grade and 0 to 105C operating temperature range make it suitable for industrial and commercial networking equipment.
The architecture separates time-critical I/O from general-purpose processing: the PowerPC core runs application and control-plane code while the CPM handles DMA-driven peripheral protocols. This dual-engine design delivers an ideal combination of price, performance, and low-power operation for routers and gateways. The integrated PCI bridge allows direct connection to PHY devices, encryption accelerators, or companion ASICs without an external bridge chip.
Typical applications include small/medium enterprise routers, VPN and firewall gateways, wireless access points, residential gateways, industrial Ethernet switches, and serial-to-Ethernet protocol converters. The ZQMIBA temperature grade (0 to 105C) covers commercial and lightly industrial deployments rather than fully extended industrial (-40 to +85C) or automotive (-40 to +125C) ranges.
Design consideration: the 516-pin PBGA package requires careful PCB stackup planning. Four or six PCB layers with dedicated power planes are recommended to maintain signal integrity on the 32-bit memory bus and PCI interfaces at full speed. Decoupling must follow the NXP reference design with bulk capacitors on each voltage rail adjacent to the BGA.

主な用途
MPC8247ZQMIBA の用途: 7 件s: Small/Medium Enterprise Routers, VPN and Firewall Gateways, Wireless Access Points, Residential Gateways, Industrial Ethernet Switches, Serial-to-Ethernet Protocol Converters, Print and Imaging Servers.
Small/Medium Enterprise Routers
The MPC8247ZQMIBA's integrated PowerPC G2_LE core running at 266 MHz, combined with dual 10/100 Ethernet MACs and PCI expansion, makes it well suited for SME router designs where the CPM offloads packet processing from the core. In a typical deployment, the CPM handles Ethernet framing, IPsec offload to a companion accelerator, and WAN protocols, while the PowerPC core runs the routing control plane. The 1.5V core and 3.3V I/O supply rails align with standard router power architectures. The 0 to +105C junction rating covers indoor wiring closet installations.
おすすめ
VPN and Firewall Gateways
The MPC8247ZQMIBA's CPM, dual Ethernet ports, and PCI bus for crypto accelerators fit VPN/firewall gateway designs that need deterministic packet handling. The 266 MHz PowerPC core runs policy and management code while the CPM manages DMA-driven encryption descriptor chains to a PCI-attached security engine. Two PCI interfaces allow one to be dedicated to the accelerator while the second connects to additional peripherals. The 516-PBGA package supports the BGA-grade thermal performance required for fanless VPN appliances with sealed enclosures.
おすすめ
Wireless Access Points
Wireless access points benefit from the MPC8247ZQMIBA's combination of Ethernet MAC, USB 1.1 (for Bluetooth/Wi-Fi companion modules), and PCI (for 802.11 a/b/g MAC/PHY cards). The CPM handles 802.11 management frame DMA while the core runs the access point control and bridging logic. The 3.3V I/O simplifies interfacing to 3.3V PHY devices commonly used in mid-2000s Wi-Fi designs. Power consumption fits within typical PoE-powered access point budgets when clock-gating is enabled in the CPM.
おすすめ
Residential Gateways
Residential gateways combine WAN Ethernet, LAN switching, VoIP, and sometimes DSL or cable modem interfaces. The MPC8247ZQMIBA provides the dual Ethernet, USB 1.1 for storage or printer sharing, and PCI for VoIP or modem daughter cards. The PowerPC core handles the routing/NAT/UPnP stack while the CPM maintains line-rate packet forwarding. The 0 to +105C operating range covers indoor residential environments with elevated ambient temperatures in attic or garage installations.
おすすめ
Industrial Ethernet Switches
Industrial managed Ethernet switches use the MPC8247ZQMIBA as the management and control plane processor, with the CPM and PCI handling switch fabric configuration and management frame parsing. The dual 10/100 Ethernet MACs serve as out-of-band management ports, while PCI connects to the main switch ASIC. The 1.5V/3.3V split rail architecture matches typical industrial switch power designs. The 105C junction rating supports sealed industrial cabinets, though the operating temperature window starts at 0C rather than -40C.
おすすめ
Serial-to-Ethernet Protocol Converters
Serial-to-Ethernet converters use the MPC8247ZQMIBA's CPM HDLC/SDLC channels to ingest legacy serial traffic and the Ethernet MACs to forward encapsulated packets. The PowerPC core runs the conversion engine and management interface, while the CPM handles serial DMA at line rate. The integrated design eliminates external serial controller ASICs. The 516-PBGA provides ample thermal headroom for industrial converter installations with multiple active serial ports.
おすすめ
Print and Imaging Servers
Network print servers and imaging appliances leverage the MPC8247ZQMIBA's USB 1.1 host, Ethernet, and PCI for connecting to print engines or scanner heads. The CPM handles USB and Ethernet DMA, freeing the PowerPC core for image processing or print job queuing. The 266 MHz core is sufficient for low-to-mid resolution imaging. The integrated peripherals reduce BOM cost compared to designs requiring separate USB and Ethernet controller chips.

設計ノート
Estimated: at core voltage 1.5V, I/O 3.3V, full 266 MHz operation with both Ethernet MACs and PCI active, the MPC8247ZQMIBA dissipates roughly 2.0 to 2.5W. The 516-PBGA package requires a multi-layer PCB with a solid ground plane beneath the BGA to keep junction temperature within the 0 to +105C range. Use thermal vias under the package's exposed die-attach pad and provide at least 4 oz copper or copper coins on inner layers for high-volume production.
The 516-PBGA at 1.0 mm or 1.27 mm pitch demands a 4-layer or 6-layer PCB stackup with dedicated VCC (1.5V), VCCO (3.3V), and ground planes. Microstrip routing must be impedance-controlled (50 ohm single-ended, 100 ohm differential) for the memory bus and PCI signals. Place bulk decoupling capacitors adjacent to each BGA quadrant with 0.1 uF + 10 uF combinations per the NXP reference design.
Sequence the 1.5V core rail before the 3.3V I/O rail at power-up, or use a common NXP reference design that ties both rails to a tracking supervisor. The MPC8247ZQMIBA specifies that the core voltage must reach 1.5V within 50 ms of the I/O rail reaching 3.3V; failure to sequence may cause latch-up. Use a power-good reset supervisor (such as the NXP MC33164 or equivalent) to hold HRESET asserted until both rails are stable.
Do not substitute the MPC8247ZQMIBA with the VRMIBA speed grade without revalidating firmware timing loops that may have been tuned to 266 MHz. The ZQMIBA cannot be upgraded to VRMIBA in-circuit because boot ROM and BCSR settings assume the lower speed. Conversely, do not use a C-stepping part in a design that depends on legacy errata behavior - always cross-check against the latest NXP MPC8247 errata document for the specific stepping.
