STM32F746NGH7 - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
MPN: STM32F746NGH7 ✓ AktifSTM32F746NGH7 Ringkasan
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and communication interfaces into one compact component. The STM32F7 family hierarchy is Arm Cortex-M7 microcontroller, 32-bit RISC MCU, embedded processor, and semiconductor. Its high-performance architecture is intended for industrial controls, human-machine interfaces, communications equipment, audio processing, graphics-assisted systems, and connected products requiring more computation than entry-level Cortex-M devices.
Key verified attributes include a maximum operating frequency of 216 MHz, 1 MB (1M x 8) Flash memory, and a 216-TFBGA package measuring 13 x 13 mm. The Cortex-M7 core includes a single-precision floating-point unit supporting Arm single-precision data-processing instructions and data types. It also implements DSP instructions and memory-protection capabilities, making it suitable for real-time control, signal processing, and industrial applications.
The STM32F746xx family is designed around the Arm Cortex-M7 core and includes high-performance application features identified in the manufacturer documentation, including cache, SDRAM, TFT, and the Chrom-ART accelerator. These characteristics make the STM32F746NGH7 useful in TFT-based human-machine interfaces, communications gateways, industrial automation controllers, and embedded systems that combine control processing with graphical or signal-processing workloads.
The 216-TFBGA package supports dense PCB integration but requires careful escape routing and careful supply distribution. The small 13 x 13 mm land pattern places many interconnections in a limited area, so multilayer PCB construction, solid grounding, and manufacturer-recommended footprint and via guidance are important for reliable assembly.
A key purchasing consideration is that the verified distributor results show multiple sources, including DigiKey, Mouser, and LCSC. The LCSC result lists a starting price of USD 9.3381 and indicates stock; DigiKey states that the part ships today, but no unit price was exposed in the supplied result. Quantities, lead time, and lifecycle status should therefore be confirmed against the selected authorized distributor before procurement.
This product page consolidates verified manufacturer and distributor information, current pricing evidence, package details, comparison parameters, and application guidance. It also distinguishes directly confirmed facts from specifications that require consultation of the complete STM32F745xx/STM32F746xx datasheet.

Aplikasi Biasa
STM32F746NGH7 patut untuk 6 aplikasis: Industrial Automation Controller, TFT Human-Machine Interface, Communications Gateway, Real-Time Signal Processing, Audio Processing System, Medical Monitoring Controller.
Industrial Automation Controller
The STM32F746NGH7 fits industrial automation controllers that combine fast control-loop execution with extensive peripherals and external-memory support. Its 216 MHz Arm Cortex-M7 core and DSP instructions provide substantially more computation than a basic microcontroller, while the single-precision FPU accelerates common control and signal-processing mathematics. SDRAM support allows an engineer to connect external memory when the internal RAM requirement is insufficient for logs, graphics buffers, or protocol state. The 216-TFBGA package also preserves a compact board footprint. Final industrial suitability must be confirmed against the verified operating-temperature range and qualification status, which are not included in the supplied excerpts.
Disebarkan
TFT Human-Machine Interface
The STM32F746NGH7 is well suited to TFT human-machine interfaces because STMicroelectronics identifies TFT support and the Chrom-ART accelerator as features of the STM32F746xx platform. Its Cortex-M7 core can run the control and graphics-related workload at up to 216 MHz, while SDRAM support can provide external framebuffer or working memory. The 13 x 13 mm 216-TFBGA package supports compact display assemblies but requires multilayer PCB routing for its dense ball array. Engineers should budget interface timing, memory bandwidth, panel-driver requirements, and thermal headroom before committing to this MCU in a display-centric product.
Disebarkan
Communications Gateway
The STM32F746NGH7 can serve as the processing core of a communications gateway because its 216 MHz Cortex-M7 architecture combines a single-precision FPU, DSP instructions, and extensive STM32F7 peripherals. These resources support protocol conversion, buffering, packet processing, and real-time monitoring without the complexity of a higher-end application processor. SDRAM capability is useful when gateway software requires larger working buffers than embedded Flash and RAM alone can provide. The exact Ethernet, USB, and other peripheral configuration must be checked in the manufacturer ordering information because the supplied excerpts do not provide a complete interface matrix.
Disebarkan
Real-Time Signal Processing
The STM32F746NGH7 is appropriate for real-time signal-processing nodes that benefit from a 216 MHz Cortex-M7 core with single-precision floating-point and DSP instruction support. Those features can execute filtering, control transforms, modulation-related calculations, and sensor-conditioning algorithms more efficiently than a basic MCU. L1 cache can improve execution locality for repeated working sets, while SDRAM support allows larger algorithm or sample buffers. Engineering trade-offs include the 216-TFBGA assembly complexity, external-memory layout requirements, and the need to measure worst-case interrupt latency and thermal performance under sustained computation.
Disebarkan
Audio Processing System
The STM32F746NGH7 can serve as the control and DSP engine in an embedded audio system because its Cortex-M7 core includes single-precision floating-point support and a full DSP instruction set. Those capabilities suit mixing, filtering, gain control, decoding assistance, and real-time signal routing at up to 216 MHz. Its L1 cache and external SDRAM support can help manage larger data flows, while the compact BGA package fits space-constrained embedded products. A production design should still account for external codec or amplifier selection, audio-clock architecture, memory bandwidth, and the fact that the exact operating-temperature specifications were not present in the supplied excerpts.
Disebarkan
Medical Monitoring Controller
The STM32F746NGH7 is suitable for monitoring and diagnostic controllers when high-speed sampling, DSP, and a compact controller are required. The 216 MHz Cortex-M7 core can process sensor data while its single-precision FPU supports filtering and calibration algorithms. SDRAM support is useful for trace storage or larger working sets, and the integrated STM32F7 peripheral set can reduce the number of companion components. Medical use requires additional validation beyond component selection: engineers must verify the exact operating-temperature grade, isolation needs, safety architecture, electrical limits, and whether the intended subsystem requires a separately qualified device variant.

Catatan Desain
Use the official STMicroelectronics 216-TFBGA footprint and land-pattern guidance rather than deriving dimensions from the 13 x 13 mm body size. The dense ball array requires fanout or via-in-pad-compatible routing, especially for power, ground, and high-speed peripherals. Keep decoupling structures compact, provide a continuous ground reference where the footprint permits it, and follow the datasheet's recommended via and solder-mask-land recommendations to control assembly yield.
Design the 3.3 V supply path for both transient and sustained 216 MHz operation. Place local bulk and high-frequency decoupling adjacent to the supply and ground balls, verify the regulator's control-loop compatibility with the MCU's dynamic current profile, and avoid long shared supply branches between unrelated peripherals. Because the supplied excerpts do not contain DC or AC current data, determine run, idle, and wake-up current from the manufacturer datasheet before setting source-current limits, voltage droop targets, or battery budgets.
A 216 MHz Cortex-M7 can sustain meaningful activity in a small BGA package, so thermal design should not be inferred from package size alone. Use the manufacturer junction-temperature and package thermal data to estimate worst-case dissipation under realistic clock, Flash, SDRAM, and I/O loading. Preserve exposed copper heat-spreading paths where the package provides them, account for adjacent heat sources, and validate the assembled board across its intended ambient range. The supplied evidence does not contain thermal-resistance values, so none are assumed here.
Separate sensitive analogue, communications, and clock signals from high-current switching paths wherever the pin assignment permits. Route SDRAM and other high-speed interfaces according to the manufacturer timing and layout guidance, paying particular attention to return paths, impedance continuity, and via stubs. The 216-TFBGA geometry can force multilayer routing, so check layer-transition return paths and use short point-of-load decoupling rather than relying on distributed capacitors to compensate for long supply traces.
