KMC7448THX1400ND - 1.4GHz PowerPC G4 MPU 360-FCCBGA | NXP
MPN： KMC7448THX1400ND ✗ 停產KMC7448THX1400ND 概覽
A microprocessor (MPU) is a single-chip CPU that integrates the central processing unit, cache, memory management unit and on-chip peripherals onto a single die; the PowerPC G4 architecture builds on this base with AltiVec/VMX SIMD extensions and superscalar out-of-order execution. The MPC74xx family sits within NXP/Freescale's high-performance PowerPC microprocessor hierarchy, above the MPC7xx line and aligned with infrastructure, networking and aerospace applications that benefit from mature PowerPC software ecosystems.
Key features of the KMC7448THX1400ND include: 1.4 GHz core clock, 32-bit PowerPC architecture with AltiVec-compatible SIMD unit, 1.15 V core VDD, on-chip L1/L2 caches, integrated MMU and the standard PowerPC bus interface. The 360-FCCBGA package exposes the full PowerPC address/data bus plus JTAG, system management and interrupt pins, allowing direct attachment to platform ASICs and DDR memory bridges without external glue logic.
Typical applications include industrial control and automation systems, aerospace and defense embedded computing platforms, networking and telecommunications infrastructure, and military-grade single-board computers. The wide industrial temperature window and long-life-cycle PowerPC toolchain support position this part for programs requiring 10+ years of supply continuity rather than the latest-edge consumer silicon.
When designing with this part, ensure the 360-ball FCCBGA land pattern is routed with the controlled-impedance, matched-length layers specified in the NXP hardware design guide, and provide low-inductance decoupling within 100 mils of each VDD/VSS pair. Designers should also verify the host firmware supports PowerPC little-/big-endian boot and the platform's boot ROM vector configuration.

典型應用
KMC7448THX1400ND 適用於 6 應用s: Aerospace and Defense Embedded Computing, Industrial Control and Automation Platforms, Networking and Telecommunications Infrastructure, Military-Grade Single-Board Computers, Medical Imaging and Diagnostic Systems, Print and Imaging Pipeline Controllers.
Aerospace and Defense Embedded Computing
Defense avionics and rugged ground vehicles rely on PowerPC G4 class MPUs for deterministic 32-bit processing under harsh thermal conditions. The KMC7448THX1400ND's 1.4 GHz core, AltiVec/VMX SIMD and -40C to +105C industrial temperature window align directly with conduction-cooled VME/VPX cards and MIL-STD-810G chassis. Placed as the application CPU on a VPX payload board with DDR bridge ASIC, it executes radar signal preprocessing and crypto offload at lower power than higher-clock parts while preserving long-term supply for >10 year programs. The 360-FCCBGA package supports the fine-pitch routing needed for tight VPX layouts.
推薦
Industrial Control and Automation Platforms
Programmable logic controllers, robotic CNC controllers and substation automation equipment favor mature PowerPC silicon because the GCC/Linux and Wind River toolchains are still actively maintained. The KMC7448THX1400ND's 32-bit PowerPC G4 core, integrated MMU and on-chip L2 cache deliver deterministic real-time response for EtherCAT/MotionBus loops. Routed on a custom ATX/ETX baseboard with 360-FCCBGA land pattern, it delivers 1.4 GHz headroom for SCADA HMI rendering while sharing firmware with the lower-speed KMC7448HX1267ND when designs need thermal margin.
推薦
Networking and Telecommunications Infrastructure
Carrier-grade routers, ATCA blades and 3G/4G base-station controllers historically used PowerPC G4 processors for packet inspection and protocol termination. The KMC7448THX1400ND delivers 1.4 GHz processing across 32-bit PowerPC ISA with AltiVec acceleration that boosts IPsec/AES packet throughput. Mounted on an ATCA front board alongside a switch ASIC, it allows line-rate forwarding at multi-gigabit rates while keeping the firmware base on a familiar PowerPC ABI. The industrial temperature rating also tolerates outdoor PoE cabinet environments.
推薦
Military-Grade Single-Board Computers
Rugged VPX and VME single-board computers (SBCs) require long-life MPUs with extended-temperature screening, which is exactly where the KMC7448THX1400ND was positioned. Its 360-FCCBGA package is mounted on a VPX backplane with controlled-impedance 100-ohm differential pairs and matched-length address/data routing per the MPC7448 hardware design guide. This gives system integrators a 1.4 GHz PowerPC core that can host Curtiss-Wright/Concurrent VxWorks or LynxOS-178 MILS environments for command-and-control payloads, with the -40C to +105C window matching MIL-STD-810G thermal envelopes.
推薦
Medical Imaging and Diagnostic Systems
MRI/X-ray imaging controllers and portable ultrasound head-ends benefit from the deterministic PowerPC G4 architecture for real-time beamforming and image reconstruction. The KMC7448THX1400ND's 1.4 GHz core plus AltiVec SIMD accelerate FFT and convolution kernels on patient scans, while its industrial temperature range and BGA package suit the sealed enclosures of cart-based systems. Placed on a custom ATX medical board with isolated power and DICOM networking, it gives OEMs a long-term-stable compute engine in a market that prioritizes supply continuity over leading-edge process nodes.
推薦
Print and Imaging Pipeline Controllers
High-end production printers and industrial copiers embed PowerPC controllers for page-rendering, color matching and raster image processing. The KMC7448THX1400ND provides the 1.4 GHz throughput and AltiVec SIMD needed to rasterize 1200 dpi pages at full engine speed. Mounted on the main controller PCB alongside DRAM and image-pipeline ASICs, it allows page pipelines to feed laser engines with zero stalling under burst load. Its 360-FCCBGA land pattern is well-supported in long-life industrial printer architectures that lock firmware revisions for years.

主要差異化特點
- Balanced 1.4 GHz speed/power curve (對比KMC7448VU1700LD (1.7 GHz))
- Industrial-temperature screening vs commercial grade (對比KMC7448HX1267ND (1.267 GHz))
- Latest PowerPC G4 MPC7448 family (對比KMC755CVT400LE (MPC755 G3))
設計說明
Estimated: at 1.4 GHz core clock the MPC7448 die draws roughly 5-7 W typical from the 1.15 V rail. Without airflow or a heat-spreader attach, the 360-FCCBGA theta_J-A can quickly reach safe limits in the -40C to +105C industrial window, so pairing the BGA with a copper-invar lid and TIM is essential for avionics chassis. Validate with a Tcase-to-ambient of 45-50C as the derating target.
BGA escape routing must use a stack-up with continuous reference planes on layers 2 and (N-1); route matched-length 50 ohm traces for the 32-bit data bus, with skew control on the source-synchronous clock. Place at least 4 low-ESL 0402/0201 ceramic bypass caps within 100 mils of each VDD/VSS ball pair, with one 10 uF bulk cap near the BGA perimeter for mid-frequency decoupling.
Verify JTAG TAP ordering against the MPC7448 BSDL file before board bring-up - the JTAG 1149.1 chain must include (and only include) the MPU before system ASICs. Cold-joint risk: 360-FCCBGA requires pre-bake at 125C for >=24 hours per JEDEC J-STD-033, and assembly lines must support X-ray inspection to confirm BGA ball coplanarity before reflow.
Estimated: the PowerPC G4 address/data bus drives edges as fast as 1 ns/V into a parallel termination scheme; with the 32-bit bus operating at 133-200 MHz, apply series terminators on the MPU-to-DDR-bridge nets to suppress under/overshoot. Maintain 100 ohm differential impedance on the GTL+ reference clock traces and length-match clock to within +/- 25 ps across all loads.
