STM32F446ZCH7 概要
An STM32F4-series microcontroller is a 32-bit embedded semiconductor that combines an ARM Cortex-M processor, program Flash, SRAM, clocking, communication interfaces, analog peripherals, and general-purpose input/output in one package. This device belongs to the hierarchy of microcontroller, embedded processor, ARM Cortex-M microcontroller, STM32, and STM32F4 family. Its integration reduces component count while supporting deterministic real-time control and connected embedded designs.
The verified data identifies a maximum operating frequency of 180 MHz and 256 KB of internal Flash. STMicroelectronics describes the broader STM32F446 family as reaching 225 DMIPS and adding dual Quad-SPI, SDRAM, and audio interfaces. Specific SRAM capacity, voltage range, peripheral configurations, temperature grade, and package pin assignments were not included in the supplied source set, so these details remain unavailable for this data record.
The Cortex-M4 architecture is suited to signal-processing and control workloads because it combines general-purpose embedded processing with DSP instructions and an FPU. The STM32F446 family feature set can support high-speed peripheral control, external-memory access, communications, audio signal paths, and data acquisition. Actual performance depends on clock configuration, memory organization, firmware, peripherals enabled, and PCB implementation.
Typical uses include industrial automation, communications equipment, audio processing, embedded control, and data-acquisition systems. The 144-UFBGA package is particularly relevant to dense mixed-signal designs where the required footprint is much smaller than a conventional large-lead-count package. Its fine-pitch construction demands careful PCB layout, controlled escape routing, reliable power delivery, and assembly-process validation.
When designing around the STM32F446ZCH7, use the official STMicroelectronics product documentation for complete electrical limits, pin multiplexing, memory organization, and firmware support. Confirm the exact pinout and exposed-pad requirements before layout because the supplied verified data does not provide the complete 144-pin mapping or a manufacturer datasheet PDF URL.
This product record combines verified distributor specifications, package information, lifecycle and procurement context, and explicitly identified engineering data gaps. It is intended to support initial component selection while avoiding unsupported claims about parameters, alternatives, compliance, or package-level pin compatibility.

主な用途
STM32F446ZCH7 の用途: 6 件s: Industrial Automation Controller, Audio Signal Processing, High-Speed Communications Hub, Embedded Data Acquisition, Secure Networked Embedded Device, Motor and Motion Control.
Industrial Automation Controller
The STM32F446ZCH7 is a strong candidate for an industrial automation controller because its verified 180 MHz Cortex-M4 core provides substantially more processing headroom than entry-level 8-bit or lower-performance 32-bit microcontrollers. DSP instructions and an FPU can support control-loop calculations, data conditioning, and communication protocol handling, while the STM32F446 family description identifies SDRAM and dual Quad-SPI connectivity. The MCU can sit between sensors or actuators and Ethernet, serial, or fieldbus transceivers. Its 144-UFBGA package saves board area but requires fine-pitch PCB layout and assembly. Before design release, verify the exact peripheral map, voltage range, temperature grade, ESD requirements, and long-term availability in the manufacturer datasheet.
おすすめ
Audio Signal Processing
The STM32F446ZCH7 is suitable for audio signal processing when a compact MCU must combine real-time control with DSP capability. The verified Cortex-M4 core operates up to 180 MHz and includes DSP and FPU support according to the STMicroelectronics family description, which can accelerate filtering, mixing, modulation, and other numerical operations. The family also lists audio interfaces, allowing a design to connect an external audio codec or digital audio interface after confirming the exact device pin mapping. The MCU can process control commands and audio data concurrently through DMA and interrupts. Validate clock accuracy, supported audio interface modes, sample rates, codec voltage levels, and thermal performance before finalizing the audio path.
おすすめ
High-Speed Communications Hub
The STM32F446ZCH7 can serve as the control hub in a high-speed communications design because the verified 180 MHz Cortex-M4 performance provides headroom for packet processing, protocol management, and real-time interrupts. The STM32F446 family description identifies SDRAM and dual Quad-SPI interfaces, which can support external memory buffering and high-speed serial peripherals. These resources can complement UART, USB, Ethernet, or other communication transceivers when the exact STM32F446 variant provides the required alternate functions. Use DMA where appropriate to reduce CPU service overhead, and keep signal integrity and clocking in mind when routing high-speed interfaces. The supplied data does not confirm the final peripheral assignment, so schematic decisions require the exact datasheet.
おすすめ
Embedded Data Acquisition
The STM32F446ZCH7 is well suited to embedded data acquisition when acquisition timing, signal conditioning, and local control must be combined in one device. The 180 MHz Cortex-M4 core can manage sampling control, buffering, filtering, and communication while DSP and FPU support assist numerical processing. The family’s SDRAM capability can provide external working memory for larger sample buffers, and dual Quad-SPI can connect to serial memories or fast peripherals. Pair the MCU with suitable analog front-end components and an ADC according to the system’s required bandwidth and accuracy. The supplied verified data does not identify the ADC resolution or sampling rate for this exact MPN, so those parameters must be verified before selecting the analog signal chain.
おすすめ
Secure Networked Embedded Device
The STM32F446ZCH7 can support a networked embedded device when local control and communication must share one microcontroller. Its verified 180 MHz 32-bit Cortex-M4 platform and 256 KB Flash provide room for protocol stacks and application firmware, while the STM32F446 family’s listed SDRAM and Quad-SPI resources can expand storage and peripheral capacity. A practical architecture places the MCU beside an Ethernet PHY, nonvolatile storage, and a supervisory interface, then uses DMA and interrupts for data movement. Security requirements such as authentication, encryption, secure boot, and key storage are not established by the supplied source data and must be evaluated independently. Confirm package pin multiplexing and external-component voltage compatibility before layout.
おすすめ
Motor and Motion Control
The STM32F446ZCH7 is a plausible fit for compact motor and motion-control systems because its 180 MHz Cortex-M4 core can execute control algorithms alongside communications and supervisory logic. DSP and FPU support can be useful in filtering, transforms, and real-time numerical operations, while the family’s external-memory and serial-peripheral resources can support larger control software and fast sensor interfaces. Pair the MCU with appropriately rated gate drivers, power stages, position sensors, and protection circuitry; the MCU itself is not a power device. The verified data does not provide timer features, motor-control peripherals, PWM resolution, or electrical operating limits for this exact code. Verify those items and thermal conditions in the official documentation.

設計ノート
The STM32F446ZCH7 uses a 144-UFBGA package, so the PCB layout must be based on the official ball map and land pattern rather than an inferred generic BGA drawing. Route power and ground first, keep high-current and sensitive analog regions separated, and use short escape paths for high-speed interfaces. Confirm the exposed-pad or thermal-via requirements from STMicroelectronics documentation before fabrication; the supplied data does not include the package drawing or ball map.
Do not finalize the power tree from the 180 MHz and 256 KB figures alone. The STM32F446 family’s SDRAM, Quad-SPI, audio, and other peripherals can add dynamic current and transient demand, especially at high peripheral activity. Obtain the exact device electrical limits from the manufacturer datasheet, then size decoupling, regulators, and supply paths with appropriate transient margin. The supplied verified data does not provide the MCU operating-voltage range or current consumption.
Treat clock, debug, and high-speed serial routes as constrained signals even though the supplied data only identifies the 180 MHz maximum CPU clock. Keep the clock source and sensitive analog paths away from noisy switching nodes, maintain continuous return paths, and validate timing margins with the actual peripheral configuration. Use the STM32F446 family documentation and reference designs for recommended pin multiplexing and peripheral-specific layout guidance.
Do not treat STM32F446 family features or a distributor cross-reference result as proof that a different ordering code is drop-in compatible. The verified material identifies 180 MHz, 256 KB Flash, Cortex-M4, and 144-UFBGA, but it does not provide complete electrical limits, temperature grades, pin mappings, or a confirmed replacement. Verify the exact order code, package ballout, firmware support, and operating conditions before substituting or releasing production files.
コンプライアンス情報
The supplied verified data does not provide compliance declarations for the STM32F446ZCH7. Compliance status must be confirmed from current STMicroelectronics product documentation and distributor records.
