STM32F446VCT7 概要
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and interface controllers on one chip. The STM32F446 belongs to the Arm Cortex-M4 class of 32-bit RISC embedded processors, combining deterministic real-time control with digital signal processing and single-precision floating-point capabilities. Within the broader product hierarchy, it is an MCU, then a semiconductor, then an embedded processing component designed to operate directly within a larger control or communication system.
The most prominent verified features are a 180 MHz maximum core frequency, 225 DMIPS advertised for the family, 256 KB Flash, and 128 KB SRAM. The Cortex-M4 processor includes DSP and FPU resources suitable for filtering, transforms, control loops, and audio-related computations. The STM32F446 family also adds interfaces identified by STMicroelectronics, including dual Quad SPI, SDRAM capability, and audio interfaces, giving designers multiple paths for connecting sensors, displays, storage, and network or audio peripherals.
As a 100-LQFP device, the STM32F446VCT7 supports a compact, widely visible surface-mount assembly while exposing substantially more I/O than smaller 48-pin or 64-pin STM32 packages. Exact peripheral assignments, pin multiplexing, voltage limits, timers, communication channels, and electrical characteristics were not supplied in the verified excerpts and must therefore be confirmed in the manufacturer datasheet before schematic or PCB signoff. The same applies to programming, debug, clock-tree, and power-supply details.
Typical uses include industrial automation modules, motor and motion-control platforms, communication equipment, audio interfaces, data-acquisition systems, and connected embedded products. For a new design, use STM32CubeMX or the STM32CubeIDE ecosystem to generate startup code, configure clocks and peripherals, and organize the HAL or low-level driver layer. Validate the final operating frequency against the selected power-supply voltage and the device temperature range before deployment.
The most important procurement and design checks are exact package pin compatibility, firmware-device support, memory requirements, peripheral availability, operating-temperature grade, and lifecycle continuity. Because no verified pin list was included in the supplied data, a complete 100-pin map should be taken directly from the manufacturer package documentation rather than inferred. This page consolidates verified source facts, practical integration considerations, and sourcing information while clearly separating verified values from specification gaps.
For procurement, distributors list the STM32F446VCT7 from $8.3394 at LCSC as of 2026-10-22, and DigiKey and Mouser product pages provide additional availability and ordering information. Price and inventory remain time-sensitive, so confirm current stock, authorized-channel status, and volume pricing before issuing a purchase order. This information is intended to support engineering selection and does not replace the manufacturer reference manual, datasheet, errata, or qualification report.

主な用途
STM32F446VCT7 の用途: 6 件s: Industrial Automation Controller, Motor and Motion Control, Data Acquisition and Signal Processing, Embedded Audio Interface, Communications and Networked Embedded Module, Secure Connected Sensor Hub.
Industrial Automation Controller
The STM32F446VCT7 fits industrial automation controllers because its Cortex-M4 core runs up to 180 MHz and provides DSP/FPU resources for responsive control tasks. With 256 KB Flash and 128 KB SRAM, it can support control logic, local data processing, diagnostics, and human-machine-interface updates. The 100-LQFP package exposes a generous pin count for sensors, actuators, communication transceivers, and digital I/O. Design engineers should still verify the exact UART, timer, ADC, and communication assignments in the manufacturer pin table, and should validate industrial temperature and EMC requirements before production release.
おすすめ
Motor and Motion Control
The STM32F446VCT7 is appropriate for compact motor-control and motion-control platforms requiring deterministic embedded computation. Its 180 MHz Cortex-M4 performance and DSP/FPU capability can accelerate control-loop mathematics, while the 100-LQFP package provides a practical number of external connections for gate drivers, position sensors, communications, and protection signals. The design must confirm timer channels, encoder interfaces, PWM outputs, ADC channels, and pin alternates against the exact STM32F446VCT6/VCT7 documentation. External gate drivers, current sensing, isolation, and thermal protection remain system-level requirements rather than functions automatically supplied by the MCU.
おすすめ
Data Acquisition and Signal Processing
The STM32F446VCT7 can serve as the central processor in a data-acquisition or embedded signal-processing system. Its DSP instructions, FPU, 180 MHz operating capability, 256 KB Flash, and 128 KB SRAM provide a useful balance for filtering, calibration, measurement control, and local buffering. Dual Quad SPI and SDRAM-related family resources can also support high-speed peripherals and external data movement. The verified excerpts do not specify ADC resolution, converter rates, DAC availability, or DMA channel mappings, so those parameters must be checked directly in the datasheet before selecting analog front-end components.
おすすめ
Embedded Audio Interface
The STM32F446VCT7 is suitable for embedded audio-interface applications because STMicroelectronics identifies audio interfaces in the STM32F446 family, while the Cortex-M4 DSP and FPU resources support real-time audio mathematics. The 100-LQFP package can provide the required connections for an audio codec, control lines, clocks, storage, and communications. Validate the exact audio interface, DMA routing, sample-rate support, and pin multiplex options in the manufacturer documentation. External amplifier, codec, clocking, and isolation circuitry will determine whether the MCU is suitable for a particular consumer, industrial, or communications product.
おすすめ
Communications and Networked Embedded Module
The STM32F446VCT7 can serve as the host processor in communications equipment or a networked embedded module, subject to the exact peripheral configuration. Its 180 MHz Cortex-M4 core provides application-processing headroom, and the verified STM32F446 family description highlights dual Quad SPI, SDRAM, and audio interfaces. These resources can complement Ethernet or serial-interface hardware, but the MCU itself does not automatically provide every network function. Select an external Ethernet controller when required, route communications pins according to the package table, and validate protocol timing, DMA performance, memory bandwidth, and thermal conditions during integration.
おすすめ
Secure Connected Sensor Hub
The STM32F446VCT7 is suitable for a connected sensor hub when the design needs more processing capability than a small entry-level MCU. Its 256 KB Flash and 128 KB SRAM provide room for firmware, protocol stacks, calibration data, and local filtering, while the Cortex-M4 DSP/FPU resources can process sensor data before transmission. The 100-LQFP package allows integration of multiple digital interfaces and external connectivity components. For IoT deployments, verify the exact peripheral mix, low-power modes, security features, operating-temperature range, and long-term supply before finalizing the platform.

設計ノート
Confirm the exact STM32F446VCT7 supply-voltage range, regulator sequencing, and decoupling requirements from the manufacturer datasheet before laying out the power tree. The verified excerpts identify a 180 MHz maximum core frequency but do not provide the voltage-versus-frequency table. Do not assume that the same voltage, current, and decoupling design applies to every STM32F446 suffix. Provide local bulk and high-frequency decoupling close to the device pins, keep analog and digital return currents controlled, and validate startup and brownout behavior in the final board design.
Use the official 100-LQFP package drawing and complete pin table rather than relying on a generic STM32 footprint library. Place the MCU in a location that preserves short, controlled connections for clocks, reset, boot, debug, communications, and high-speed interfaces. Account for exposed or sensitive analog functions, ground references, and decoupling placement. Because no complete verified pinout was supplied, every alternate-function decision must be cross-checked against the exact package revision and datasheet before Gerber release.
If the design uses SDRAM, fast external memory, high-speed serial interfaces, or LCD signals, route them with the reference-impedance and topology specified by the manufacturer and the connected peripheral. Keep clocks and data paths short, control return paths continuously, avoid unnecessary vias, and provide appropriate termination and series damping where required. The verified family page confirms SDRAM and dual Quad SPI support, but it does not establish the exact electrical constraints; derive the final interface design from the official datasheet and application guidance.
Avoid selecting a related STM32F446 variant based only on the family name. Suffixes can affect package, memory, temperature grade, clock settings, and ordering format. In particular, the supplied alternatives include devices in 64-LQFP and 144-LQFP packages, which are not pin-to-pin compatible with the 100-LQFP STM32F446VCT7. Confirm the exact orderable MPN, package dimensions, pin count, memory map, peripheral set, and firmware support before treating any part as a drop-in replacement.
コンプライアンス情報
The supplied verified excerpts do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than inferred.
