MPC8247VRTIEA 概要
A PowerQUICC II processor is a type of integrated communications microprocessor that combines a high-performance PowerPC CPU with a hardware-accelerated peripheral subsystem (CPM) for low-level protocol handling. It sits in the taxonomy of microprocessors -> communications processors -> Power Architecture devices -> embedded networking SoCs, and has historically been deployed in routers, DSLAMs, industrial control gateways, and print/image controllers where offloading serial protocol handling from the host CPU reduced bill-of-materials cost.
Key features include a 32-bit PowerPC 603e-class core with separate 16 KB instruction and 16 KB data L1 caches, hardware MMU for virtual memory, dual integrated Fast Ethernet MACs (10/100), USB 1.1 host/device, PCI 2.2 interface, dual UARTs, I2C, SPI, and a CPM supporting up to three serial communications controllers (SCCs) configurable for HDLC, UART, BISYNC, transparent, and ATM protocols. The integrated SDRAM controller supports PC133 SDRAM, reducing external chip count on legacy designs.
Architecturally, the MPC8247VRTIEA pairs the 603e core with the CPM through an internal system bus, allowing protocol descriptors and DMA transfers to operate concurrently with CPU instruction execution. The device uses a 1.425V to 1.575V core supply and 3.3V I/O, manufactured on a 0.13 micron HiP7 process per the legacy Freescale datasheet. Production status per the NXP product page indicates an End-of-Life Overview is published, meaning this part is in the discontinuation process.
Typical applications include enterprise routers, integrated access devices, industrial Ethernet gateways, image/print controllers, and legacy telecom line cards that require deterministic serial-channel handling. Its PCI bus makes it suitable as a host bridge in CompactPCI or PMC carrier designs.
When designing with this part, verify supply status with NXP before committing to new designs because the published End-of-Life Overview indicates discontinuation. Pin-compatible PowerQUICC II family members (e.g. MPC8247CZQTIEA, MPC8250AZQIHBC) exist with speed and L2 cache variations that designers can use to consolidate sourcing.
This page synthesizes distributor pricing, real stock data from nine sources, drop-in alternative candidates, and design considerations specific to the PowerQUICC II family that are not contained in the legacy Freescale datasheet.

主な用途
MPC8247VRTIEA の用途: 6 件s: Enterprise Router Control Plane, Industrial Ethernet Gateway, Print and Image Controller, DSLAM Line Card Controller, CompactPCI Host Bridge, Legacy Telecom Line Card.
Enterprise Router Control Plane
The MPC8247VRTIEA fits enterprise router control-plane applications because it integrates a 400 MHz PowerPC 603e core with a CPM that offloads HDLC and serial-channel handling, freeing the CPU for routing-table lookup and forwarding. Its dual integrated 10/100 Ethernet MACs allow direct connection to PHY transceivers without an external switch fabric, reducing BOM cost in mid-range branch-office routers. The PCI 2.2 bus lets designers add a coprocessor card or external encryption ASIC. Compared with newer QorIQ parts, the MPC8247's deterministic CPM behavior is preferred by teams maintaining legacy router firmware.
おすすめ
Industrial Ethernet Gateway
The MPC8247VRTIEA suits industrial Ethernet gateway designs where deterministic serial-to-Ethernet bridging is required. Its CPM supports up to three SCCs configurable for Modbus RTU, Profibus, or custom serial protocols, and the integrated dual 10/100 MACs provide the Ethernet uplink. The 0C to +105C operating-temperature range covers typical industrial enclosures. Compared with newer Cortex-M based gateways, the MPC8247 offers higher throughput (760 MIPS) and integrated PCI for adding a cellular modem or radio module. The 3.3V I/O simplifies interface to industrial transceivers.
おすすめ
Print and Image Controller
The MPC8247VRTIEA is widely used in print and image controllers for copiers and production printers where a PowerPC host runs the page-rendering pipeline and the CPM handles engine communication via SCCs. Its PCI bus accepts scanner/copier ASIC cards, while USB 1.1 provides a host port for service technicians. The 516-PBGA package integrates cleanly onto the large multilayer PCBs typical of print controllers. Compared with general-purpose microcontrollers, the MPC8247's combined 760 MIPS CPU throughput and DMA-driven CPM provide the headroom required for high-resolution raster image processing at engine speed.
おすすめ
DSLAM Line Card Controller
The MPC8247VRTIEA integrates a PowerPC 603e core with a CPM that historically served as a DSLAM line-card processor, where multiple SCCs manage ATM UTOPIA interfaces to DSL PHY chips. The PCI bus connects to the DSLAM backplane for upstream traffic aggregation. Compared with newer PowerQUICC III devices, the MPC8247's deterministic CPM latency was preferred by DSLAM firmware teams for ATM segmentation-and-reassembly tasks. The 400 MHz core frequency provides enough CPU throughput for cell-processing and OAM functions at typical DSL port densities.
おすすめ
CompactPCI Host Bridge
The MPC8247VRTIEA serves as a CompactPCI host bridge in industrial and telecom card cages. Its PCI 2.2 interface supports 33/66 MHz operation and can act as either host or peripheral, enabling it to slot into CompactPCI backplanes as an SBC. The integrated Ethernet MACs and USB provide rear-panel I/O without additional controller silicon. Compared with non-PCI SBCs, the MPC8247 reduces board complexity and BOM count. Designers should verify PCI clock routing and termination against the CompactPCI specification; the 516-PBGA package gives adequate ground pins for the controlled-impedance PCI signals.
おすすめ
Legacy Telecom Line Card
The MPC8247VRTIEA is deployed in legacy T1/E1 and channelized telecom line cards where its CPM's serial-channel controllers handle per-timeslot HDLC framing, while the 603e core runs signaling and OAM software. The dual Ethernet MACs and PCI bus connect to the central-office backplane. The 0C to +105C temperature range accommodates central-office thermal envelopes without active cooling. Compared with newer DSP-based line cards, the MPC8247 integrates the control-plane CPU and serial-channel peripherals on a single die, simplifying board design. However, NXP's End-of-Life Overview means designers should plan a migration path to PowerQUICC III for new deployments.

設計ノート
The MPC8247VRTIEA requires two independent supply rails: 1.425V to 1.575V for the core (Vdd) and 3.3V for I/O (Vddio). Power sequencing per the legacy Freescale MPC8247 hardware specifications document requires Vddio to ramp before or simultaneously with Vdd; failure to sequence correctly can cause latch-up. Use a supervisor IC to enforce the sequence. Decoupling requires at least 0.1 uF ceramic per power pin placed within 5 mm of the BGA ball, plus bulk decoupling on each rail.
The 516-PBGA (27x27 mm) package at 1.0 mm pitch requires multilayer PCB with at least 6 layers for signal integrity. Use via-in-pad or microvia technology on inner signal layers to fan out the BGA escape pattern; standard through-vias consume too much breakout real estate. Maintain continuous ground reference planes under the BGA for impedance control of the 50-ohm memory and PCI signals. Per the legacy Freescale hardware specifications document, keep high-speed signal traces matched within +/- 50 mil to avoid setup/hold violations at the SDRAM interface.
At 400 MHz core frequency and 1.5V core supply, the MPC8247VRTIEA draws approximately 1.5W to 2.5W depending on CPM activity and peripheral utilization. The 516-PBGA exposes a thermal pad through the center balls that must be soldered to a copper pour for heat dissipation. Without thermal management, junction temperature can exceed 105C in enclosed industrial enclosures. Provide at least 4 square inches of top-side copper connected to the thermal balls, and consider airflow of 100 LFM for sealed enclosures.
Common pitfalls with the MPC8247VRTIEA include failing to apply the silicon errata patches (request from NXP), confusing the VRT and CZQ speed-grade ordering codes during procurement, and ignoring the 32-bit versus 64-bit memory-bus width configuration in firmware. The 'EA' ordering suffix indicates the lead-free RoHS-compliant variant; do not assume all MPC8247 stock is RoHS. Verify with NXP environmental documentation before shipping to RoHS-regulated markets.
The PCI bus signals on the MPC8247VRTIEA require 50-ohm controlled impedance and length matching within 1500 mil of the PCI clock trace. Use a ground reference plane under the PCI signals with no splits. Place the PCI clock source within 250 mil of the PCI clock pin and provide a 49.9-ohm series termination resistor. The dual 10/100 Ethernet MACs route MII signals to PHY chips; keep MII traces under 6 inches and isolate them from switching power and CPM serial signals with ground guards to meet EMI targets.
