MPN: MC7447AHX1167NB ✗ Akhir HidupMC7447AHX1167NB Ringkasan
A PowerPC G4 (MPC74xx) microprocessor is an implementation of the PowerPC RISC architecture targeted at high-end embedded computing, networking, and signal processing. Within the broader taxonomy it sits under microprocessor (MPU) -> processor -> integrated circuit -> semiconductor. The MPC7447A family specifically added AltiVec vector processing and a larger on-die L2 cache, narrowing the gap between general-purpose embedded CPUs and DSP-class compute pipelines. Compared with earlier MPC74xx parts, the 7447A extended SIMD throughput and cache capacity without breaking pin compatibility with established 360-FCCBGA footprints.
Key features include seven-stage super-scalar pipeline, hardware multiply-accumulate, 32 KB instruction and 32 KB data L1 caches, 512 KB unified L2 cache with cache locking, eight instruction BAT and data BAT registers, JTAG IEEE 1149.1 boundary scan and on-chip debug, thermal sensor and POR/PLL block. The AltiVec unit executes 128-bit vector operations in a single cycle, accelerating signal-processing kernels. The 64-bit MPX bus supports multiprocessor coherency with external logic.
Architecturally, the MPC7447A uses an out-of-order execution engine with a unified reservation station and a 128-entry branch history table. Power management is supported through doze, nap, and sleep modes driven by MSR and HID registers. The 1.1 V core reduces power compared with prior 1.3 V or 1.5 V members of the family, while the configurable I/O voltage (1.8 V or 2.5 V) simplifies integration with mixed-voltage peripherals. Performance at 1.167 GHz delivers strong integer and vector throughput for embedded workloads.
Typical applications include embedded networking control (routers, switches, line cards), industrial automation controllers, software-defined radio baseband, military/aerospace signal processing, and high-performance embedded computing for medical imaging or test & measurement. Its long-life cycle and ruggedized temperature range make it suitable for designs that demand longevity beyond consumer-product horizons.
When designing with this MPU, ensure your board layout uses the 360-FCCBGA (25x25 mm) land pattern with proper via-in-pad or dog-bone escape for the inner rows. Provide clean, low-noise 1.1 V core and 1.8 V/2.5 V I/O rails with bulk decoupling, and respect the multiprocessor bus timing if more than one 7447A is used. Always check NXP's PCN notices for this part: the MC7447AHX1167NB is listed as End-of-Life, so design teams should plan a last-time-buy window or migrate to the recommended NXP replacement identified in the official PCN.

Aplikasi Umum
MC7447AHX1167NB cocok untuk 6 aplikasis: Embedded Networking Line Cards, Software-Defined Radio Baseband, Industrial Automation Controllers, Military and Aerospace Signal Processing, Test and Measurement Instrumentation, Medical Imaging Compute.
Embedded Networking Line Cards
The MC7447AHX1167NB's 1.167 GHz PowerPC G4 core, 128-bit AltiVec engine, and 64-bit MPX multiprocessor bus make it well suited to embedded networking line cards such as router blades, switch fabric controllers, and packet-processing engines. The 512 KB on-chip L2 cache absorbs routing-table lookups, while AltiVec accelerates parallel pattern matching and CRC computation. Designers can place two or more 7447A devices on a shared MPX bus for symmetric multiprocessing.
Direkomendasikan
Software-Defined Radio Baseband
In software-defined radio baseband processing, the MC7447AHX1167NB delivers 1.167 GHz of PowerPC compute plus single-cycle 128-bit AltiVec vector math, enabling real-time FFT, FIR filtering, and channelization on a single MPU. The 105 C thermal rating supports ruggedized enclosures, while the 1.1 V core reduces power dissipation in size-constrained radios. The 64-bit MPX bus streams digitized RF into the L2 cache for sustained DSP workloads.
Direkomendasikan
Industrial Automation Controllers
Industrial automation controllers benefit from the MC7447AHX1167NB's deterministic PowerPC pipeline, 512 KB unified L2 with cache locking for real-time code, and 105 C thermal rating for factory-floor enclosures. AlpinVec SIMD accelerates motion-control inverse kinematics and PLC scan loops. The 1.1 V core reduces heat in dense DIN-rail or backplane assemblies, and the 360-FCCBGA package fits standard SOM (system-on-module) form factors.
Direkomendasikan
Military and Aerospace Signal Processing
Military and aerospace signal-processing subsystems often require long-life-cycle, ruggedized MPUs - exactly the niche the MC7447AHX1167NB was designed for. Its 1.167 GHz core and AltiVec vector engine handle radar pulse compression, electronic-warfare demodulation, and image-processing chains. The 105 C junction rating and ceramic-style FCCBGA package support harsh-environment deployments. Designers should consult NXP PCN status carefully for last-time-buy planning.
Direkomendasikan
Test and Measurement Instrumentation
Test and measurement instruments such as oscilloscopes, protocol analyzers, and logic analyzers need a fast deterministic CPU plus vector DSP - both delivered by the MC7447AHX1167NB. AltiVec accelerates FFT-based spectrum analysis, while the 64-bit MPX bus keeps deep acquisition memory streaming to the processor. The 360-FCCBGA fits modular instrument card cages that follow the established MPC7447A reference designs.
Direkomendasikan
Medical Imaging Compute
Medical imaging platforms such as ultrasound beamformers and portable MRI front-ends benefit from the MC7447AHX1167NB's AltiVec SIMD, which accelerates image-reconstruction kernels including FFT, convolution, and back-projection. The 512 KB L2 cache keeps working image data on-chip for high throughput, while the 1.1 V core supports fanless designs required in clinical environments. Designers should follow IEC 60601 isolation guidance around the MPU's I/O rails.

Diferensiator Kunci
- Faster speed bin than the 1.0 GHz MPC7447A member (vsMC7447ATHX1000NB)
- Larger L2 cache than the lower-cost MPC7445 family (vsMC7445AHX1400-NNB)
- Pin-compatible path to the higher-clock MPC7448 family (vsMC7448HX1267ND)
Catatan Desain
The 360-FCCBGA (25x25 mm) package requires a high-density PCB stack-up. Use 0.8 mm or 1.0 mm pitch BGA land patterns with non-solder-mask-defined pads and via-in-pad micro-vias (typically 0.1 mm laser-drilled) for inner-row signal escape. Match trace impedance to 50 ohms for the MPX bus and provide solid ground/power planes adjacent to every signal layer to control the 64-bit bus skew budget.
Estimated: At 1.167 GHz with a typical MPC7447A power envelope near 10-12 W, design a 6-layer board with at least two dedicated core 1.1 V planes and one Ovdd 1.8 V / 2.5 V plane. Place 22 uF bulk + 100 nF high-frequency ceramic decouplers within 5 mm of each BGA power quadrant. Use a remote-sense feedback to the regulator to compensate for board-level IR drop on the 1.1 V core rail.
Estimated: The 360-FCCBGA thermal resistance (theta_JA) is approximately 12 C/W with proper thermal-via array under the die, allowing 10-12 W dissipation at 105 C junction in still air. Drill a 4x4 thermal-via array under the central die flag and tie them to internal ground planes for heat spreading. In enclosed industrial enclosures, derate ambient by 10-15 C or add a small heatsink.
Do not use the MC7447AHX1167NB in new designs without first reviewing NXP's PCN. The family is End-of-Life, so plan a last-time-buy window or migrate to the recommended NXP replacement. Ensure your bootloader/OS image targets the same MPC7447A mask revision, otherwise power-on reset behavior, HID bits, and PLL configuration may differ between speed bins.
