MC7448VU1000LD 概要
Key features include a 1.0 GHz clock speed, a 1.15 V core voltage, a wide I/O voltage range of 1.8 V to 2.5 V, and a junction operating range up to 105 C. The MPC7448 line is the most significant product update in the MPC74xx lineage, offering superscalar out-of-order execution, hardware MMU, and the AltiVec vector unit for high-throughput signal processing.
Technically, the MC7448VU1000LD uses the PowerPC e600 core, a superscalar implementation of the Power Architecture instruction set with separate 32 KB L1 instruction and data caches, a tightly-coupled 1 MB L2 cache with on-chip tag RAM, a 64-bit wide MPX/60x system bus, and an integrated thermal management unit that triggers frequency throttling or alerts at high junction temperatures. The 360-FCCBGA package exposes the full MPX bus plus JTAG/COP debug pins.
Typical applications include networking equipment (routers, switches, edge appliances), industrial computing, single-board computers, network-attached storage, and embedded control platforms. The combination of high single-thread performance and AltiVec SIMD makes it particularly suitable for packet processing and signal-conditioning workloads.
When designing with this part, pay close attention to the multi-rail power architecture (separate VDD core at 1.15 V and I/O at 1.8 V/2.5 V), install proper thermal management up to 105 C junction, and use a 4-layer+ PCB with controlled-impedance routing for the MPX/60x bus. The part contains lead and is supplied in tray packaging for OEM and industrial customers.

主な用途
MC7448VU1000LD の用途: 6 件s: Edge Networking Router, Single-Board Industrial Computer, Network-Attached Storage Controller, Print Image Processor / Embedded Imaging, Aerospace / Defense Ruggedized Platform, Test & Measurement Instrumentation.
Edge Networking Router
The MC7448VU1000LD suits edge-router designs that need single-thread packet-processing speed at low cost. Its 1.0 GHz PowerPC e600 core with 1 MB L2 cache delivers wire-rate forwarding on Fast Ethernet and basic Gigabit Ethernet ports. The AltiVec SIMD engine accelerates IPSec AES/SHA hashing, IPS/IDS string matching, and DPI regex workloads by 4-8x versus scalar code. Designers typically run VxWorks or Linux on this MPU, using the MPX/60x bus to attach a routing ASIC or Ethernet switch fabric. Power consumption at 1.15 V core and 1.0 GHz stays around 10-15 W, which the 360-FCCBGA package dissipates without active heatsinks in 1U chassis.
おすすめ
Single-Board Industrial Computer
For industrial SBCs the MC7448VU1000LD provides PC-like compute density in a fanless 105 C envelope. The 32 KB/32 KB split L1 and 1 MB on-die L2 enable real-time control loops and HMI rendering on the same die. The 360-FCCBGA package is socket-compatible with a CPU card form factor widely used in VME and cPCI platforms, allowing upgrades from older MC7447 boards by dropping in the LD variant. Firmware uses U-Boot and a real-time Linux kernel; the AltiVec unit handles floating-point DSP blocks for motor-control and encoder feedback. Lead-containing BGA chemistry is acceptable inside sealed industrial enclosures.
おすすめ
Network-Attached Storage Controller
The MC7448VU1000LD powers mid-range NAS controllers that need AltiVec-accelerated CRC and RAID parity calculation. Single-core 1.0 GHz with on-chip L2 is sufficient for hundreds of MB/s sustained throughput to SATA disks. The 64-bit MPX/60x bus connects directly to a PCI-X bridge that fans out to SATA and Ethernet MACs. Power dissipation stays low enough for a compact 4-bay NAS chassis without forced cooling. Runnig an embedded Linux with a journaling filesystem (ext4 or btrfs) leverages the 1 MB L2 as a write-back buffer to mask disk latency.
おすすめ
Print Image Processor / Embedded Imaging
Engineers building high-speed multifunction printers use the MC7448VU1000LD to drive the raster image processor (RIP) and the scanner pipeline. AltiVec accelerates JPEG2000 wavelet kernels and 8-bit color-space conversions in real time. The 1 MB L2 holds an entire A4 page at 600 dpi in compressed form, eliminating off-chip memory access during a single page rotation. The MPX/60x bus connects to a memory controller that drives DDR SDRAM and to a custom ASIC for the print engine. Operating at 1.15 V keeps heat low enough to share a chassis with the scanner lamp without thermal runaway.

Aerospace / Defense Ruggedized Platform
Ruggedized MIL-STD computing platforms benefit from the MC7448VU1000LD's ceramic FCCBGA package, which tolerates extended thermal cycling and vibration up to 105 C junction. Lead-based BGA solder joints survive conformal coating and the lead-free exemption flow. The PowerPC architecture has long-standing support in RTOS ecosystems (VxWorks 653, INTEGRITY) used in avionics and naval systems. The MC7448 family also has a longer mean-time-between-failure profile than consumer-grade MCUs, critical for 20-year defense programs. AltiVec performs radar FFT and sonar beamforming on the same die without offloading to DSPs.
おすすめ
Test & Measurement Instrumentation
Bench-top test gear uses the MC7448VU1000LD as the main compute engine for protocol analyzers and oscilloscopes. The deterministic MPX/60x bus with its published timing allows synchronization with sample ADCs at sub-nanosecond resolution. AltiVec runs FFT and digital-filter kernels on streaming 16-bit acquisition data at GSPS rates, freeing the host CPU for display rendering. The 360-FCCBGA in a 6-layer PCB keeps emissions inside EN 61326-1 limits for industrial test gear. U-Boot plus a custom Linux manages the front-panel UI over the I2C controller bridged from the MPX bus.

主な差別化要因
- Highest-frequency 1.0 GHz member of the leaded MPC7448 family （vs MC7448VU1000LC)
- Larger 1 MB L2 vs the older MPC7447 family （vs MC7447AVU1000LB)
- Lower-cost entry point than higher-speed MPC7448 variants （vs MC7448VU1267LD)
設計ノート
Decouple the 1.15 V core supply with 4-6 ceramic capacitors per rail (220 nF X7R minimum) placed within 5 mm of the FCCBGA balls. The I/O rails at 1.8 V and 2.5 V need their own bulk decoupling of 22 uF tantalum plus 100 nF ceramic. Sequence the rails in datasheet order (core before I/O) to prevent internal latch-up; failure to do so can permanently damage the silicon.
Estimated: at 1.0 GHz and full SIMD utilization, the part dissipates approximately 10-15 W. The 360-FCCBGA package thermal resistance is approximately 1.5 C/W with a properly-attached heatsink and 200 LFM airflow. Junction temperature rises 15-22 C above ambient at 10 W; design for a maximum ambient of 80 C to keep Tj below 105 C. Use thermal interface material rated for the leaded BGA metallurgy.
Use a minimum 4-layer PCB with dedicated power and ground planes. The MPX/60x bus operates at 133 MHz with setup/hold times in the 1-2 ns window - route with controlled impedance of 50 ohm single-ended and length-match within +/- 25 mil. The 360-ball BGA pitch (1.27 mm typical for CBGA) requires 0.20 mm via-in-pad or microvia escape routing; standard through-hole vias cause signal-integrity issues at this density.
Do not hot-plug the MC7448VU1000LD - its MPX/60x bus signals are not designed for live insertion. Power sequencing must be enforced by external reset logic, never by polling the COP/JTAG port alone. Be aware that the LD suffix contains lead - if the end-product requires RoHS, the LC variant must be substituted.
コンプライアンス情報
Contains lead per manufacturer datasheet. RoHS non-compliant by design; use LC variant for RoHS-compliant builds. AEC-Q100 not applicable - select MC7447AVU1000LB for automotive.
