STM32F446MEY6TR 概要
A microcontroller is a semiconductor device that integrates a processor core, memory, and peripherals into one package. The STM32F4 series belongs to the embedded-processing hierarchy: Arm Cortex-M core, 32-bit RISC processor, microcontroller, and embedded semiconductor. This integration reduces board area and lets firmware control communications, data acquisition, timing, storage, and external equipment through dedicated peripherals.
The verified manufacturer information identifies a maximum operating frequency of 180 MHz, 512 KB of Flash, 225 DMIPS, an FPU, DSP instructions, dual Quad SPI, SDRAM support, and audio interfaces. The STM32F446 family therefore fits designs where compute performance and compactness matter more than a large general-purpose package. Its BGA-style WLCSP construction also requires careful PCB layout, assembly process control, and inspection because board-level rework is less straightforward than with exposed-leaded packages.
The ARM Cortex-M4 core provides deterministic control alongside accelerated floating-point and digital signal processing. This combination is useful when control loops must execute quickly alongside filtering, transforms, audio processing, or sensor-data conditioning. The 512 KB program Flash provides more local code space than many entry-level microcontrollers, although the supplied sources do not state RAM capacity, exact peripheral mappings, voltage limits, or package pin definitions.
Typical uses include compact industrial control, audio processing, communications equipment, digital signal acquisition, and embedded systems that benefit from external SDRAM. The family's dual Quad SPI can support high-bandwidth serial devices, while SDRAM and audio interfaces provide expansion paths for data-intensive or multimedia designs. Firmware and board support must be selected for the exact STM32F446 device variant.
The primary engineering consideration is the 81-WLCSP assembly footprint. Its 3.80 mm by 3.69 mm area supports miniaturization but demands manufacturer-qualified PCB design rules, fine-pitch assembly capability, appropriate solder-paste control, and reliable inspection. Users should download the official datasheet and package drawing before assigning signals or releasing a layout.
This page consolidates verified manufacturer and distributor information, exact pricing evidence, package constraints, and engineering guidance. It also distinguishes confirmed facts from missing technical data rather than inferring unverified RAM, pinout, electrical limits, or replacement details.

主な用途
STM32F446MEY6TR の用途: 6 件s: Compact Audio Processing, Industrial Data Acquisition, Embedded Communications Controller, Digital Signal Conditioning, External SDRAM Data Systems, Portable Connected Device.
Compact Audio Processing
The STM32F446MEY6TR fits compact audio processing because its verified 180 MHz Arm Cortex-M4 core, DSP capability, FPU, and audio interfaces support real-time filtering and signal transformation. The 512 KB Flash provides local space for control code and fixed audio algorithms, while SDRAM support can accommodate larger sample buffers when required. The 81-WLCSP package, measuring 3.80 mm by 3.69 mm, also helps reduce board area. The tradeoff is assembly complexity: fine-pitch WLCSP requires qualified PCB rules, solder-paste control, inspection, and careful analog or digital clock layout. Firmware developers should confirm the exact audio peripheral mapping and electrical limits in the official datasheet before production.
おすすめ
Industrial Data Acquisition
The STM32F446MEY6TR is suitable for compact industrial data-acquisition equipment when a fast control engine is needed alongside serial sensing and communication tasks. Its 180 MHz Cortex-M4 core and DSP instructions can accelerate filtering or calibration work, while the FPU supports arithmetic-heavy sensor conditioning. Dual Quad SPI provides a route to high-speed serial sensors, memory, or peripheral devices, and the 512 KB Flash supports embedded firmware. In an acquisition controller, the MCU could aggregate channels, apply digital filters, and publish results through another serial interface. Use the exact package drawing and pin-level electrical documentation before layout, and verify isolation, grounding, protection, and EMC requirements at the analog front end.
おすすめ
Embedded Communications Controller
The STM32F446MEY6TR can serve as the central controller in compact communications equipment because the STM32F446 family combines up to 180 MHz processing, 225 DMIPS, dual Quad SPI, and SDRAM support. Those resources allow protocol processing and external data movement to coexist with application logic. In a communications controller, the MCU could manage a fast serial link, maintain packet or control buffers, and coordinate status reporting. The 81-WLCSP footprint supports compact modules but requires assembly capability and careful high-speed layout. Clock integrity, power sequencing, impedance control, ESD protection, and thermal validation must be designed around the final connector and transceiver rather than inferred solely from the MCU datasheet.
おすすめ
Digital Signal Conditioning
The STM32F446MEY6TR is well matched to digital signal-conditioning tasks because its Cortex-M4 core operates up to 180 MHz and includes DSP and FPU support. These features make the device useful for filtering, sensor fusion, FFT-related processing, and real-time control loops where processing headroom affects latency. The 512 KB Flash can hold firmware and fixed tables, while SDRAM support is useful when working sets exceed internal memory. A practical signal-chain controller would acquire samples through a serial interface, perform deterministic numeric processing, and forward results to another subsystem. Validate numeric throughput, memory bandwidth, interrupt latency, and peripheral timing against the actual workload; the headline 180 MHz frequency alone does not guarantee a particular control-loop performance.
おすすめ
External SDRAM Data Systems
The STM32F446MEY6TR is appropriate for compact systems that need more data storage than local program memory alone because the STM32F446 family explicitly includes SDRAM support. External SDRAM can hold frame buffers, trace samples, audio buffers, or graphics-related data while the 512 KB Flash stores firmware. The MCU manages the external memory alongside ordinary control logic, making it useful in embedded gateways and specialized signal-processing products. SDRAM placement and routing require strict bus timing, decoupling, controlled impedance, and length-matching rules from the MCU datasheet. The compact WLCSP package reduces board area but can make escape routing and assembly more demanding, so use the vendor-referenced memory topology and validate signal integrity on prototypes.
おすすめ
Portable Connected Device
The STM32F446MEY6TR can support a portable connected device when compact size, real-time control, and a broad set of serial peripherals are important. The 180 MHz Cortex-M4 core can manage user-interface state, sensor processing, and communications tasks, while the 81-WLCSP package preserves board area in a dense enclosure. Dual Quad SPI, audio interfaces, and SDRAM support provide options for sensors, local storage, and sound. Battery-powered implementations must still account for regulator efficiency, sleep behavior, peak current, thermal rise, and antenna layout. The supplied sources do not provide the device's detailed low-power specifications, so those values must be obtained from the official datasheet before estimating battery life.

設計ノート
Treat the 81-WLCSP as a fine-pitch assembly design rather than a conventional leaded MCU. Use the manufacturer package drawing for ball coordinates, pad geometry, solder mask, paste apertures, courtyard, and reflow profile. Confirm that the PCB fabricator supports the package pitch and that the assembly house can inspect hidden joints. Do not derive land geometry from a generic WLCSP symbol because ball-map and pad details are device-specific.
The STM32F446MEY6TR is a performance-oriented Cortex-M4 device with external SDRAM, audio, and high-speed serial options, so power planning must include regulator headroom, peak I/O activity, SDRAM current, and temperature rise. The supplied sources do not state operating voltage, current consumption, or thermal resistance, so those values must be taken from the official datasheet before selecting regulators or copper areas. Estimated power calculations are not valid until those verified inputs are available.
Route high-speed serial and SDRAM signals with the exact topology and timing constraints in the STM32F446 hardware documentation. Keep clocks away from noisy switching nodes, provide continuous return paths, use appropriate decoupling near the device, and validate the first article with an oscilloscope or protocol analyzer. The verified data confirms SDRAM and dual Quad SPI support, but it does not provide trace-length, impedance, or timing values; those must come from the official design documentation.
Do not treat a 180 MHz Cortex-M4 rating, a 512 KB Flash value, or a shared STM32F4 family name as proof that another MCU is interchangeable. Cross-family parts may differ in package, memory map, peripherals, clock tree, interrupts, and firmware support. For a redesign, start with the exact STM32F446ME suffix datasheet, pin table, memory map, and package drawing, then recompile and retest the complete firmware.
コンプライアンス情報
The supplied manufacturer and distributor snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Obtain current declarations from STMicroelectronics or the authorized distributor before release to production.
