MC7448VS1400ND 概要
A microprocessor (MPU) is an integrated circuit that contains the CPU, cache, bus controller and memory management in a single package. The MC7448VS1400ND belongs to the broader PowerPC G4 family, itself a member of the Power Architecture instruction set lineage used in embedded computing, networking and aerospace systems. Within the system hierarchy, the MPU sits above peripherals and below the chassis/board level, providing general-purpose compute and SIMD acceleration to the host platform.
Key features include a 1.4 GHz clock frequency, 1.1 V core supply, a 360-pin FCCLGA ceramic package, 1 MB of on-die L2 cache with ECC support, hardware virtualization hints, and a 60x/MPX coherent bus for multiprocessor topologies. The MPC7448 silicon revision enables 21.3 Dhrystone 2.1 MIPS at 1.4 GHz and incorporates the AltiVec 128-bit vector unit for media and signal-processing workloads.
Typical applications span embedded routers, industrial imaging, defense/aerospace compute modules, single-board computers (SBC), and legacy PowerPC-based VME/cPCI cards where deterministic Power Architecture compute is required. The FCCLGA ceramic package supports the wide industrial and military temperature grades, making the part suitable for harsh-environment deployments.
When designing with this MPU, ensure the platform supplies a clean 1.1 V core rail with adequate decoupling and thermal management for a 21 W-class power envelope. Pair the device with a compatible northbridge and boot firmware that supports the 60x bus protocol; verify the FCCLGA land pattern matches the chosen PCB stackup.

主な用途
MC7448VS1400ND の用途: 6 件s: Embedded Networking Routers, Single-Board Computers (VME / cPCI), Industrial Imaging and Vision Systems, Defense and Aerospace Compute Modules, Medical Imaging Front-Ends, Industrial Automation Controllers.
Embedded Networking Routers
The MC7448VS1400ND fits embedded router line cards because its MPX/60x coherent bus integrates cleanly with MPC107/MPC8540-class northbridges, while the 1.4 GHz PowerPC G4 core delivers the headroom needed for packet-classification and forwarding pipelines. AltiVec accelerates bulk crypto and IPsec bulk transforms, offloading the CPU by 2-4x versus scalar code paths. The 360-FCCLGA ceramic substrate supports the long-life, NEBS-compliant thermal envelopes typical of central-office routers, where ambient temperatures near 70 C require an MPU rated to 105 C junction. Power is approximately 21 W at 1.4 GHz, so a copper heat spreader and 1 sq-in top-side copper pour are recommended for sustained throughput.
おすすめ
Single-Board Computers (VME / cPCI)
The MC7448VS1400ND is a well-suited SBC compute element because its 360-FCCLGA package and MPX bus map cleanly to the legacy VME64 and cPCI SBC layouts still used in defense and industrial automation. The 1.4 GHz speed grade and 1 MB L2 cache deliver the deterministic single-thread performance required for real-time control loops, while AltiVec accelerates DSP-style signal-conditioning kernels used in sonar, radar and machine-vision payloads. The 105 C junction rating covers the closed-chassis thermal environment of a typical 6U VME card; pairing the MPU with a discrete LDO for the 1.1 V core rail keeps the switching-noise floor below the part's analog PLL sensitivity.
おすすめ
Industrial Imaging and Vision Systems
The MC7448VS1400ND's AltiVec 128-bit SIMD engine makes it a strong fit for industrial imaging pipelines that perform per-pixel convolution, color-space conversion, and JPEG/MPEG encode in software. At 1.4 GHz the core sustains roughly 21.3 Dhrystone 2.1 MIPS, and AltiVec boosts image-processing kernels by 4-8x versus scalar execution, allowing line-scan cameras and X-ray imaging front-ends to hit 60 fps without a dedicated DSP. The 1 MB L2 cache absorbs frame-buffer stalls when the MPX bus is busy, and the 360-FCCLGA ceramic package tolerates the 24/7 thermal load of factory-floor vision enclosures where ambient temperatures fluctuate between 5 C and 55 C.
おすすめ
Defense and Aerospace Compute Modules
The MC7448VS1400ND is a proven fit for defense and aerospace programs that require PowerPC G4 compute in extended-environment modules, including avionics data concentrators and flight-test instrumentation. The FCCLGA ceramic substrate, lead-free RoHS finish, and 105 C junction rating match the mechanical and thermal envelopes of conduction-cooled CCIL/CCIL-style line-replaceable modules. The MPX bus enables deterministic dual-CPU configurations used in primary/standby flight-control pairs, and AltiVec supports sensor-fusion DSP without burdening the host. For high-altitude or naval applications, pair the part with a conformal-coated PCB stack and verify the FCCLGA solder column metallurgy against the program's tin-whisker mitigation plan.
おすすめ
Medical Imaging Front-Ends
The MC7448VS1400ND supports medical imaging front-ends such as MRI reconstruction pre-processors and CT scanner data acquisition boards, where the AltiVec engine accelerates back-projection kernels and per-voxel convolutions. The 1.4 GHz clock sustains real-time reconstruction for lower-resolution modalities without an FPGA or GPU coprocessor, simplifying FDA-510(k) qualification by reducing the bill of materials. The 1 MB L2 cache and MPX/60x coherent bus also support dual-MPU patient-monitoring topologies. Designers should still validate the deterministic interrupt latency for IEC 60601-1 compliant isolation boundaries and provide a redundant supervisory MCU for safety-class functions.
おすすめ
Industrial Automation Controllers
The MC7448VS1400ND fits industrial automation controllers running PowerPC-aware real-time operating systems, where the 1.4 GHz PowerPC G4 core and 1 MB L2 cache deliver the deterministic single-thread performance required for PLC scan loops and motion-control algorithms. The MPX/60x bus preserves the legacy MPC8260/MPC8349 software stack, easing migration from older controllers without re-validating firmware, while AltiVec accelerates floating-point trajectory planning. The 360-FCCLGA ceramic package is rated to 105 C and tolerates the vibration profile of a typical cabinet-mounted controller. Pair the MPU with isolated RS-485/Profibus transceivers and a watch-dog supervisor for IEC 61131-3 compliance.

主な差別化要因
- Highest stock clock speed in the MPC7448 family at 1.4 GHz （vs MC7448VU1000LD)
- 90 nm SOI process vs the older 0.13 micron process in the MPC7447A die （vs MC7447AVU1000LB)
- 1 MB L2 cache versus 512 KB on the MPC7447A predecessors （vs MC7447AHX1000LB)
設計ノート
The MC7448VS1400ND draws roughly 21 W from the 1.1 V core rail at 1.4 GHz. Use a low-impedance LDO or DC-DC converter with a 1% tolerance feedback divider and place at least six 10 uF X5R ceramic bulk capacitors around the FCCLGA perimeter to keep the core supply ripple below 30 mV pk-pk during AltiVec bursts. Verify the DC-DC current rating accounts for the worst-case 130% load-step transient caused by L2 cache line evictions.
The 360-FCCLGA ceramic package exposes the die through the top surface and is rated to 105 C junction. For sustained 1.4 GHz operation, attach a copper heat spreader with thermal interface material (TIM) and provide at least 1 square inch of top-side copper. Estimated: with theta_JA of approximately 12 C/W and a 21 W load, the junction rises about 252 C above ambient; therefore, adequate forced-air cooling or a conduction-cold-plate is mandatory for any deployment above 30 C ambient.
Route the MPX/60x bus as a controlled-impedance differential pair with 50 ohm single-ended / 100 ohm differential impedance, keep trace lengths matched within 25 mils, and place the MPC107 northbridge within 4 inches of the MPU. Provide matched-length address and data buses to avoid MPX bus hold-time violations; break out all 360 FCCLGA balls on a 1.0 mm pitch grid using 0.8 mm micro-vias, and reserve a continuous ground pour beneath the entire MPU footprint for return-current continuity.
Do not assume MPC7447 and MPC7448 firmware is binary-compatible - the MPC7448 silicon revision changes the L2 cache line-replacement policy and the AltiVec context-save opcode. Do not substitute a plastic BGA version of the MPC7448 (if any exist) without re-qualifying the thermal profile, because the FCCLGA ceramic substrate has a much lower theta_JC than a plastic BGA. Finally, verify the part-number suffix matches your temperature grade: 'VS' denotes 0 C to 105 C, while 'THX' denotes -40 C to 105 C.
