STM32F446MEY6TR Übersicht

STMicroelectronics STM32F446MEY6TR is an Arm Cortex-M4 32-bit RISC microcontroller operating up to 180 MHz, with 512 KB of Flash memory and DSP and FPU capability, in an 81-WLCSP package measuring 3.80 mm by 3.69 mm. The device is positioned for compact, high-performance embedded systems requiring substantial processing speed, local program storage, and extensive serial peripherals.

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.

Typische Anwendungen

STM32F446MEY6TR ist geeignet für 6 Anwendungs: 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.

🏭

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.

🌐

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.

📡

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.

🖥️

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.

📱

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.

What are the key specifications of STM32F446MEY6TR that engineers should know?
The STM32F446MEY6TR combines an Arm Cortex-M4 core, 180 MHz maximum frequency, 512 KB Flash, 225 DMIPS, DSP and FPU support, and dual Quad SPI in an 81-WLCSP package. STMicroelectronics describes the wider STM32F446 family as supporting SDRAM and audio interfaces. The package measures 3.80 mm by 3.69 mm, making it exceptionally compact but demanding qualified fine-pitch PCB assembly. These figures come from the verified STMicroelectronics and DigiKey product information dated October 22, 2026.
What is the operating frequency of STM32F446MEY6TR?
The STM32F446MEY6TR operates at up to 180 MHz. According to the verified STMicroelectronics product page, STM32F446xC/E devices use a high-performance Arm Cortex-M4 32-bit RISC core, and the STM32F446 family is specified at 225 DMIPS. Clock-tree configuration, voltage conditions, and firmware limits must still be selected from the official technical documentation for the final design.
How much Flash memory does STM32F446MEY6TR contain?
The STM32F446MEY6TR contains 512 KB of Flash memory, organized as 512K x 8 according to the verified DigiKey listing. This provides substantially more program storage than entry-level Cortex-M devices. RAM capacity was not present in the supplied sources, so it must be confirmed in the official datasheet before sizing buffers, stacks, or real-time data structures.
What package does STM32F446MEY6TR use?
The STM32F446MEY6TR uses an 81-WLCSP package measuring 3.80 mm by 3.69 mm. Verified distributor results also describe it as 81-UFBGA or 81-pin WLCSP, reflecting marketplace terminology for the same fine-pitch assembly class. Because the exact package drawing is not included in the supplied data, use the official STM32F446ME datasheet and land-pattern document before PCB release.
Where can I download the STM32F446MEY6TR datasheet PDF?
The official STM32F446ME product page is the preferred starting point for the manufacturer datasheet and supporting documentation. The verified page is https://www.st.com/en/microcontrollers-microprocessors/stm32f446me.html. Octopart also provides a datasheet aggregation link, but engineer should confirm document identity and revision against STMicroelectronics before using it as the controlled copy.
Where can I find the STM32F446MEY6TR pinout and land pattern?
The STM32F446MEY6TR pinout should be obtained from the official STM32F446ME datasheet and the corresponding 81-WLCSP package drawing. The supplied search results confirm an 81-ball package but do not provide individual ball assignments, so no reliable pin list can be generated without risking incorrect connectivity. Use the package drawing for land pattern, courtyard, solder mask, and assembly dimensions.
Where can I buy STM32F446MEY6TR online?
STM32F446MEY6TR is offered by DigiKey, Mouser, LCSC, the ST online store, and other listed distributors. The verified LCSC result reports an in-stock price starting at $8.5354 as of October 22, 2026. Availability changes rapidly, so confirm the exact suffix, package, lead time, and authorized-channel status before placing a production order.
What is the price of STM32F446MEY6TR?
The verified lowest listed price is $8.5354 per unit from LCSC as of October 22, 2026. DigiKey and Mouser provide purchasing and pricing links but their snippets do not expose numerical price tiers. Because only one numerical distributor quote was supplied, the tiers in this record use that price without inventing volume discounts, taxes, freight, or negotiated pricing.
Is STM32F446MEY6TR in stock?
The verified LCSC listing explicitly reports the STM32F446MEY6TR as in stock and shows a starting price of $8.5354 as of October 22, 2026. The DigiKey snippet says it ships today but does not disclose a quantity. Stock status can change rapidly, so confirm the required order quantity directly with the seller before committing a build schedule.
What is the lead time for STM32F446MEY6TR?
A numeric factory or distributor lead time cannot be verified from the supplied results. LCSC showed the part in stock on October 22, 2026, while DigiKey stated that it ships today, but neither snippet provides a guaranteed quantity-specific lead time. For purchasing, request a written quotation for the exact quantity and include the reel orientation, dry-pack status, and date-code requirements.
STM32F446MEY6TR vs STM32F411RET6TR — which is better for high-performance embedded control?
Choose STM32F446MEY6TR when the design requires its verified 180 MHz Cortex-M4 performance, 225 DMIPS, DSP, FPU, dual Quad SPI, SDRAM capability, and audio interfaces. STM32F411RET6TR is a different package and memory configuration, so it cannot be treated as a pin-compatible drop-in replacement despite sharing an STM32 family identity. The appropriate choice depends on timing, storage, peripherals, package, and software requirements.
What is the difference between STM32F446 and STM32F4 series alternatives?
The STM32F446 provides up to 180 MHz operation and 225 DMIPS according to STMicroelectronics, with dual Quad SPI, SDRAM, audio interfaces, DSP, and FPU support. Other STM32F4 devices may match some general capabilities but differ in memory, package, peripherals, clocking, and pin assignment. Cross-family substitution therefore requires a full electrical, pinout, firmware, and lifecycle review rather than relying on the Cortex-M4 label.
When should I choose STM32F446MEY6TR over a lower-performance STM32 MCU?
Choose STM32F446MEY6TR when processing headroom, floating-point or DSP work, high-rate serial peripherals, external SDRAM, or audio connectivity justify the fine-pitch 81-WLCSP assembly. A simpler STM32 MCU may be preferable when the application needs less compute or a more serviceable package. The decision should balance firmware workload, I/O requirements, assembly capability, thermal behavior, and total system cost.
Is STM32F446MEY6TR suitable for compact audio and communications equipment?
The STM32F446MEY6TR is suitable for compact audio and communications prototypes when 180 MHz processing, DSP, FPU, dual Quad SPI, SDRAM support, and audio interfaces align with the design. Its 3.80 mm by 3.69 mm package enables miniaturization, while the 512 KB Flash provides local firmware capacity. Production use still requires validated acoustic, RF, power, thermal, and signal-integrity implementation.
What can replace STM32F446MEY6TR as a drop-in part?
No verified drop-in replacement was identified from the supplied cross-reference results. The only named Cortex-M4 competitors—NXP LPC43xx, Microchip ATSAM4E, and Texas Instruments TM4C123x—do not establish an 81-WLCSP footprint and pin-to-pin compatibility with STM32F446MEY6TR. They are architectural alternatives, not drop-in replacements. A PCB change, software port, and full qualification would be required.
Is STM32F446MEY6TR the same as a GD32, NXP, or Microchip Cortex-M4 MCU?
No. STM32F446MEY6TR, GD32 devices, NXP LPC43xx devices, Microchip ATSAM4E devices, and TI TM4C123x devices may share the Arm Cortex-M4 execution model, but they do not necessarily share package dimensions, ball assignments, peripherals, interrupts, memory map, clock tree, or firmware support. They cannot be treated as identical parts, and no cross-brand drop-in replacement was verified in the supplied data.

Wichtigste Unterscheidungsmerkmale

  • High-performance processing in a compact package (vs. STM32F446RGT6)
  • Dedicated high-speed serial and external-memory capability (vs. STM32F446CET6)
  • Audio and DSP-oriented embedded platform (vs. STM32F446VGT6)
  • Documented manufacturer ecosystem (vs. STM32F446MECT6)

Designhinweise

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.
