STM32F446RCT7TR - 180MHz 256KB Cortex-M4 MCU | STMicroelectronics
MPN: STM32F446RCT7TR ✓ نشطSTM32F446RCT7TR نظرة عامة
A microcontroller is a compact embedded-computing component that integrates a processor core, memory, peripherals, and communication interfaces onto one semiconductor device. The STM32F4 family belongs to the hierarchy of 32-bit MCU, embedded processor, microcontroller, and semiconductor. STM32F446 devices are designed for applications requiring real-time control, data processing, and multiple peripheral resources within a single integrated circuit.
The verified product information identifies an Arm Cortex-M4 core, 32-bit processing, a maximum operating frequency of 180 MHz, and 256 KB of Flash memory. The Cortex-M4 core supports digital signal-processing and floating-point workloads as identified by distributor descriptions. These characteristics make the MCU suitable for connected industrial equipment, sensor systems, audio equipment, medical instrumentation, and embedded control platforms.
The STM32F446RCT7TR is offered in a 64-pin LQFP surface-mount package. The distributor listing identifies the package as 64-LQFP 10 x 10 mm, while another distributor description uses 64-Pin PQFP terminology for the same ordering code. The manufacturer product page describes the STM32F446xC/E family as based on a high-performance Arm Cortex-M4 32-bit RISC core operating up to 180 MHz.
Typical applications include industrial automation, communication equipment, audio processing, medical devices, and networked embedded products. The device can serve as the central controller for real-time signal acquisition, motor or actuator control, communications bridging, and low-power supervisory functions. Exact peripheral assignments, voltage limits, memory-map details, and electrical operating limits should be confirmed in the manufacturer datasheet before design release.
When designing around the STM32F446RCT7TR, engineers should preserve the package footprint, verify all exposed-pin assignments, provide suitable decoupling, and confirm the selected STM32F4 power, clock, and memory configuration against the board schematic. Firmware migration should also account for the exact STM32F446xC device variant and its documented peripheral configuration.
This page consolidates verified distributor specifications, manufacturer family information, application guidance, and drop-in alternative analysis for engineers evaluating STM32F446RCT7TR designs.

التطبيقات النموذجية
STM32F446RCT7TR مناسب لـ 6 التطبيقs: Industrial Automation Controller, Audio Signal Processing, Connected Sensor Node, Medical Monitoring Equipment, Communication Equipment, LED Lighting and Display Control.
Industrial Automation Controller
STM32F446RCT7TR fits an industrial automation controller because its Arm Cortex-M4 core operates up to 180 MHz and includes DSP and FPU capability. The device can coordinate sensor acquisition, control logic, communications, and actuator timing in one embedded platform. Its 256 KB of Flash provides storage for a substantial firmware image, while the 64-pin LQFP package supports a conventional surface-mount PCB layout. Because the supplied data does not specify the full peripheral list or temperature range, the final design should verify industrial timing, EMC, isolation, and environmental requirements.
موصى به
Audio Signal Processing
STM32F446RCT7TR is a reasonable candidate for audio signal processing because the verified distributor data identifies DSP and FPU capability on an Arm Cortex-M4 core operating up to 180 MHz. Those resources support digital filtering, mixing, effects, and real-time signal calculations while the MCU consolidates control and processing functions. The 64-pin LQFP package leaves a defined footprint for a surface-mounted board, and 256 KB of Flash supports embedded firmware. Audio performance still depends on the external codec, sampling interface, memory availability, clocking, and analog design.
موصى به
Connected Sensor Node
STM32F446RCT7TR can serve as the control processor in a connected sensor node where local filtering, protocol handling, and real-time decisions are required. The 180 MHz Cortex-M4 core provides computational headroom, while DSP and FPU support can reduce the complexity of sensor-data processing. Its 256 KB of Flash is useful for protocol stacks and application firmware, and the 64-pin LQFP package supports compact board construction. The verified snippets do not specify RAM, exact peripheral functions, or wireless capability, so a sensor-node design should confirm those resources before finalizing the architecture.
موصى به
Medical Monitoring Equipment
STM32F446RCT7TR may be evaluated for medical monitoring equipment that requires a compact real-time controller and high-performance 32-bit processing. The verified Arrow listing describes the device as suitable for 2.5 V/3.3 V medical-oriented supply information, while the Cortex-M4 core operates up to 180 MHz and supports DSP/FPU processing. These features can assist with sensor conditioning, digital filtering, alarm logic, and user-interface control. Medical use requires separate verification of accuracy, safety, EMC, reliability, software validation, and applicable regulatory requirements; those claims are not supplied here.
موصى به
Communication Equipment
STM32F446RCT7TR is suitable for communication equipment when the design needs local protocol handling and real-time control alongside a network interface. The Arm Cortex-M4 core can execute communications tasks at up to 180 MHz, and the DSP/FPU features may assist with signal-related calculations. The 64-pin LQFP package provides a defined surface-mount footprint, while 256 KB of Flash supports embedded firmware. The supplied data does not confirm the exact Ethernet, USB, UART, or other peripheral configuration, so interface assignments and timing must be checked in the manufacturer documentation.
موصى به
LED Lighting and Display Control
STM32F446RCT7TR can control complex LED lighting or display systems where timing, dimming, communication, and system supervision must be handled together. The 180 MHz Cortex-M4 core offers more processing headroom than needed for basic blinking or static control, while DSP and FPU capability can support calibration and visual algorithms. Its 64-pin LQFP package is practical for a surface-mounted controller, and 256 KB of Flash accommodates application logic. The supplied snippets do not list the MCU’s exact PWM, display, or communication peripherals, so these functions must be verified before schematic capture.

ملاحظات التصميم
The verified distributor listing identifies 2.5 V/3.3 V supply information for STM32F446RCT7TR. Before layout release, verify the exact operating-voltage range, regulator tolerances, decoupling requirements, and power-sequencing requirements in the official STM32F446RC documentation. Place bulk and high-frequency decoupling close to the appropriate supply and ground pins, and confirm the regulator’s transient response against the selected clock and load conditions.
Use the official 64-pin LQFP 10 x 10 mm mechanical drawing rather than relying only on a distributor package description. Preserve the recommended pad geometry, solder-mask clearance, assembly allowance, and pin-1 orientation. Confirm whether the selected variant and package suffix use the same exposed-pad or thermal-pad arrangement as the chosen PCB footprint; an incorrect footprint can prevent assembly or cause electrical failures.
At the verified maximum clock frequency of 180 MHz, clock and high-speed signal integrity become board-level design concerns. Route clock lines over continuous ground reference planes, minimize stubs and unnecessary vias, keep sensitive analog and digital return currents separated, and validate rise/fall behavior with the actual load, trace geometry, and external components. The supplied snippets do not specify the complete peripheral mapping, so signal assignment must come from the official datasheet.
Do not treat a related STM32F4 ordering code as a confirmed drop-in substitute merely because the family name is similar. The cross-reference search supplied a comparison page but did not verify identical Flash capacity, RAM, pin mapping, temperature grade, voltage limits, or peripheral functions. Compare the exact MPN suffixes and manufacturer mechanical and electrical documents before purchasing substitutes or reusing a PCB footprint.
