料号： STM32F746VET6TR ✓ 量产中STM32F746VET6TR 概述
A microcontroller is a programmable system-on-chip that integrates a CPU core, nonvolatile program memory, data memory, peripherals, and communication interfaces on one package. The STM32F746 belongs to the STM32F7 high-performance microcontroller family and combines an Arm Cortex-M7 core with embedded flash and RAM resources. Its hardware peripherals reduce the need for external logic in connected industrial, audio, networking, and control designs.
Key verified specifications include a 216 MHz maximum operating frequency, 512 KB flash memory, 32-bit architecture, and a 100-LQFP package. The Cortex-M7 core supports single-precision floating-point instructions and a full set of DSP instructions, enabling efficient control loops and numerical workloads. The 100-LQFP package provides a conventional leaded footprint suitable for automated PCB assembly and inspection.
The STM32F746VET6TR is designed for applications that require higher processing performance than typical general-purpose Cortex-M microcontrollers while retaining a compact integrated architecture. Its DSP and floating-point capabilities are relevant to audio, motor-control, communications, and data-acquisition systems. The LQFP package also leaves generous board spacing between leads, which can simplify prototype soldering compared with fine-pitch land patterns.
Typical uses include industrial controllers, motor-drive systems, communications equipment, audio interfaces, test equipment, and embedded gateways. When designing around the MCU, verify the complete pin assignment, power-supply requirements, clock configuration, memory organization, and peripheral multiplexing against the manufacturer datasheet. Software compatibility also depends on the selected STM32F7 device, package, memory size, and application firmware.
The most important design trade-off is performance versus pin and package complexity. A 216 MHz Cortex-M7 core can reduce computational latency, but the design must account for decoupling, clock stability, thermal behavior, and correct peripheral configuration. STM32F746VET6TR is best selected when its verified flash capacity, package, and Cortex-M7 processing requirements match the product design.
This page combines verified distributor and manufacturer information, procurement data, drop-in replacement screening, and practical engineering guidance. It is intended to help engineers locate the datasheet, compare alternatives, check package compatibility, and plan an STM32F746VET6TR-based design without relying on unverified substitute assumptions.

典型应用
STM32F746VET6TR 适用于 6 应用s: Industrial Automation Controller, Motor Control and Digital Power, Audio and DSP Processing, Communications Gateway, Data Acquisition and Test Equipment, Embedded Graphical User Interface.
Industrial Automation Controller
The STM32F746VET6TR fits industrial automation control because its 216 MHz Arm Cortex-M7 core can execute communication stacks, state machines, and real-time control loops while retaining 512 KB of embedded flash. The 100-LQFP package provides a manageable leaded footprint for industrial controller assemblies. A design should verify the required UART, CAN, Ethernet, timer, ADC, and digital I/O assignments against the exact datasheet before finalizing the PCB. Use the floating-point and DSP capabilities for signal filtering or motion calculations, while accounting for EMI, grounding, and supply decoupling in the enclosure.
推荐
Motor Control and Digital Power
The STM32F746VET6TR is well suited to motor-control and digital-power prototypes because the Cortex-M7 core operates up to 216 MHz and includes single-precision floating-point and DSP instructions. These resources support current-loop calculations, transform mathematics, filtering, and timing-critical control functions. The 512 KB flash capacity provides room for control firmware, parameter tables, and communication services. Designers must confirm the exact timer outputs, ADC inputs, pin multiplexing, and PWM frequency from the datasheet, then isolate sensitive analog and power paths from the digital switching environment.
推荐
Audio and DSP Processing
The STM32F746VET6TR can support audio front ends, digital signal processing, and communications-assisted audio systems because its Cortex-M7 core includes single-precision floating-point support and DSP instructions. At 216 MHz, the device is appropriate for real-time filtering, mixing, modulation, and control tasks when memory and peripheral requirements fit the application. The 100-LQFP package is useful for prototypes because the leads are more accessible than a very fine-pitch package. Verify audio interface pins, sampling requirements, clock sources, and external codec or amplifier choices against the official documentation.
推荐
Communications Gateway
The STM32F746VET6TR is appropriate for embedded communications gateways that need deterministic control alongside protocol handling and data processing. Its 216 MHz Cortex-M7 core and 512 KB flash provide substantial headroom compared with entry-level general-purpose microcontrollers, while the DSP and floating-point features assist with signal conditioning. The 100-LQFP package simplifies access during prototype assembly and inspection. Confirm the required serial, Ethernet, USB, and memory interfaces in the exact device documentation, and include protection, impedance control, and grounding in the communication-board layout.
推荐
Data Acquisition and Test Equipment
The STM32F746VET6TR can serve as the control processor in data-acquisition and test systems requiring real-time sampling coordination, signal processing, and human-interface or communications support. The Cortex-M7’s DSP and floating-point resources help process acquired data, while 512 KB flash accommodates application firmware and configuration data. The 100-LQFP package is practical for laboratory and industrial test boards with accessible leads. Verify ADC performance, sampling architecture, external interface timing, and analog supply requirements directly in the datasheet before selecting external converters.
推荐
Embedded Graphical User Interface
The STM32F746VET6TR can support embedded human-machine interfaces because its Cortex-M7 processing capability and 512 KB flash support more involved control firmware than simple utility MCUs. The device can coordinate display updates, touch input, communications, and application logic in a compact embedded product. The exact display interface, external memory requirement, and pin multiplexing must be confirmed from the manufacturer documentation. Use the 100-LQFP package when a leaded assembly process is preferred, and keep display and touch traces away from noisy switching sources.

设计说明
Use the manufacturer power-supply and decoupling recommendations from the STM32F745xx/STM32F746xx datasheet. Place the required bulk and high-frequency capacitors close to the device power pins, keep the return path short, and separate noisy switching or motor-current paths from sensitive analog returns. The provided search data confirms a 216 MHz Cortex-M7 device and 512 KB flash but does not provide the complete supply-voltage table, so do not finalize capacitor values or voltage limits without the official datasheet.
Design the PCB around the exact 100-LQFP pinout and all alternate-function assignments for STM32F746VET6TR. Leave adequate routing space between LQFP leads, especially for clocks, high-speed memory interfaces, debug signals, and communication lines. Confirm exposed thermal and ground requirements directly from the package drawing. Because the supplied snippets do not contain the full pin table, release layout only after cross-checking every power, ground, reset, clock, and peripheral connection.
For high-speed control or communications, route clock and signal paths over continuous reference planes and keep return paths adjacent to each trace. Add series termination only where the exact interface standard, trace impedance, and edge rate require it. Avoid long stubs and unnecessary vias, and validate signal integrity with the final stack-up and firmware timing. The verified data does not specify all high-speed peripheral configurations, so interface-specific guidance must be checked against the official datasheet.
Do not treat STM32F746VGT6, STM32F745VET6, or STM32F7767VGT6 as automatic drop-in replacements solely because they are related STM32F7 devices or appear in search results. Confirm package, pinout, flash size, RAM, voltage, temperature grade, clock configuration, peripheral multiplexing, and software device identifiers. The supplied cross-reference data does not establish exact drop-in equivalence for the target MPN, so substitution requires manufacturer documentation and board-level validation.
合规信息
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
