STM32F746VGT6G - 216MHz Cortex-M7 MCU | STMicroelectronics
MPN： STM32F746VGT6G ✓ 啟用中STM32F746VGT6G 概覽
An Arm Cortex-M7 microcontroller is part of the embedded processor hierarchy: Cortex-M core, 32-bit microcontroller, embedded controller, and semiconductor. The STM32F7 family is designed for high-performance embedded applications where processing throughput, integrated memory, real-time control, and multiple communication interfaces matter more than the minimal footprint and cost of a smaller microcontroller.
The STM32F746VGT6G provides up to 216 MHz operating frequency and 1 MB of flash memory. Its 100-pin LQFP package exposes substantially more I/O than smaller STM32 devices, supporting integration with external memory, displays, communications equipment, and industrial peripherals. The G ordering suffix distinguishes this specified orderable device, while its electrical details beyond the verified product and distributor information should be confirmed against the STMicroelectronics datasheet before design release.
The STM32F746 platform uses the Arm Cortex-M7 architecture described by STMicroelectronics for the STM32F745xx and STM32F746xx families. This core is suitable for responsive control and multimedia workloads because it provides substantially greater performance than entry-level 8- or 32-bit microcontrollers. Firmware, peripherals, clocking, memory configuration, and development-software support must be checked for each exact variant rather than inferred from the family name alone.
Typical application directions include industrial control panels, communications equipment, audio and multimedia systems, data acquisition, and networked embedded products. Its 216 MHz core can support more demanding control loops and protocol processing, while the 100-LQFP package simplifies access to numerous I/O signals. The package also requires careful PCB routing and thermal design because fine-pitch leads and a large exposed land pattern must be assembled and connected correctly.
Designers should use the exact STMicroelectronics STM32F746VG documentation for pin assignment, power supplies, decoupling, clock-tree configuration, memory limits, peripheral functions, and programming. The verified distributor listings identify the device as a 32-bit, 216 MHz Cortex-M7 with 1 MB of flash, but they do not provide a complete electrical table or public pin map in the supplied data.
This page combines the verified manufacturer and distributor information with practical sourcing guidance, qualification of same-brand replacement candidates, and an explicit comparison framework. It distinguishes confirmed facts from parameters that still require datasheet verification, helping engineers make an evidence-based decision without mistaking a family-level candidate for an automatically qualified drop-in replacement.

典型應用
STM32F746VGT6G 適用於 6 應用s: Industrial Control Panels, Industrial Networking Gateways, Data Acquisition Systems, Audio and Multimedia Controllers, Human-Machine Interfaces, Connected Consumer Products.
Industrial Control Panels
The STM32F746VGT6G fits industrial control panels because its Cortex-M7 core operates at up to 216 MHz while the 100-LQFP package provides access to numerous I/O for switches, indicators, sensors, and communications links. A design can use the 1 MB of flash for control logic, diagnostics, and interface firmware without relying on external program memory. The primary benefit is faster deterministic response than an entry-level microcontroller, while the trade-off is a larger 14 x 14 mm package and more demanding PCB assembly. Before schematic release, verify the exact peripheral mix, operating-temperature range, power rails, and pin functions in the official STM32F746VG documentation.
推薦
Industrial Networking Gateways
The STM32F746VGT6G is appropriate for networking gateway control when higher processing throughput is useful for protocol management, packet handling, and local configuration. Its 216 MHz Cortex-M7 core provides more performance headroom than basic 8- or 32-bit gateway controllers, while 1 MB of flash supports firmware, web resources, and update data. The 100-LQFP package also offers more signal options for Ethernet, serial, debug, and status interfaces. Designers should account for the larger PCB footprint and verify which Ethernet and transceiver interfaces are present in the exact variant before assigning pins.
推薦
Data Acquisition Systems
The STM32F746VGT6G can serve as the central controller in a data-acquisition system that combines sensor inputs, signal conditioning, local processing, and data transfer. The 216 MHz Cortex-M7 core is useful when filtering or protocol formatting must be handled in real time, while the 1 MB flash capacity supports embedded acquisition software. Its 100-pin package offers more peripheral and I/O options than a compact MCU, making external ADC or communication isolation easier to route. The design trade-off is increased board complexity, so ADC performance, timer resources, trigger inputs, and digital I/O levels must be checked in the manufacturer documentation.
推薦
Audio and Multimedia Controllers
The STM32F746VGT6G is suitable for audio and multimedia controllers that require more compute and external interfaces than a basic microcontroller provides. The 216 MHz Cortex-M7 core can process control logic and media-related tasks, and the 1 MB of flash provides room for substantial firmware. The 100-LQFP package is useful when a design needs parallel control signals, multiple serial peripherals, or external memory connections. Audio-clock accuracy, supported display interfaces, DMA channels, and package-level peripheral availability remain variant-specific, so they must be confirmed before an audio clock tree or LCD interface is finalized.
推薦
Human-Machine Interfaces
The STM32F746VGT6G fits human-machine interface controllers that combine display updates, touch or keypad input, status indicators, and communications. Its Cortex-M7 performance at up to 216 MHz provides useful headroom for graphical or multitouch-oriented firmware, and the 100-LQFP package offers enough connections for multiple buses and display-related signals. The 1 MB flash capacity can hold UI code, fonts, and configuration data. Compared with a low-cost microcontroller, this device adds processing headroom but increases package size, power requirements, and software complexity, so display-interface and memory requirements should be validated against the exact datasheet.
推薦
Connected Consumer Products
The STM32F746VGT6G can be used in connected consumer products that need responsive application logic, multiple serial peripherals, and substantial embedded flash. At up to 216 MHz, the Cortex-M7 core supports more demanding control or connectivity firmware than a simple microcontroller, and the 100-LQFP package provides broad peripheral connectivity. The 1 MB flash capacity can hold application code and local configuration. A designer must balance this capability against board area, power use, and BOM cost. Confirm wireless-module interfaces, available RAM, low-power modes, and regulator requirements before finalizing the product architecture.

設計說明
Use the official STMicroelectronics 100-LQFP footprint and package drawing rather than drawing a generic 100-pin LQFP land pattern. Confirm pad dimensions, lead pitch, courtyard limits, paste recommendations, and the treatment of any exposed thermal area against the exact ordering code. A 14 x 14 mm land pattern has more routing area than a 48-pin package, but its 0.5 mm lead pitch still requires controlled fanout, adequate copper between pads, and assembly-capable clearances.
Do not finalize supply rails from family-level assumptions. The supplied data confirms the Cortex-M7 device and 216 MHz maximum frequency but does not state its core and I/O voltage ranges. Download the current official STM32F746VG documentation, identify every power pin and its permitted voltage, and place local decoupling exactly where the reference design and layout guidance specify. Check analog, digital, and I/O rail sequencing requirements before connecting external peripherals.
Avoid treating STM32F746VGT6G, STM32F746VGT6, and other STM32F7 variants as automatically interchangeable. The verified snippets confirm a shared 100-LQFP family format and headline performance, but they do not provide complete pin definitions, temperature grades, peripheral differences, or software-support status. For every proposed substitution, compare the official ordering tables, pin names, power architecture, boot behavior, peripheral set, and device ID before changing the BOM.
Plan the 216 MHz design around short, quiet clock and high-speed signal paths. Separate analog inputs from switching and digital return currents, use a continuous ground reference under the device, and route externally exposed communication interfaces away from clock and memory signals. If the design uses external memory or an LCD interface, use the manufacturer's reference layout and impedance guidance; the supplied data does not verify which memory or display interfaces are populated on this variant.
Estimated thermal analysis is not possible from the supplied data because the operating voltage, I/O load, junction temperature, and package thermal-resistance values are not provided. At 216 MHz, switching activity and supply voltage can influence both junction temperature and adjacent-component heating. Use the manufacturer thermal data for the exact package, provide copper and vias according to the recommended layout, and measure temperature in the final enclosure rather than treating the 1.4 mm package height as a thermal rating.
合規資訊
The supplied product and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed using the current official STMicroelectronics product documentation and material declarations.
