STM32F746IGT6E - 216MHz Cortex-M7 MCU | STMicroelectronics
N.º de pieza: STM32F746IGT6E ✓ ActivoSTM32F746IGT6E Descripción general
A microcontroller is a programmable system-on-chip that combines a CPU core, nonvolatile program memory, volatile data memory, peripherals, and communication interfaces. The STM32F746 belongs to the STM32F7 family of high-performance microcontrollers, where the Cortex-M7 core operates within the broader hierarchy of embedded processor, real-time microcontroller, and semiconductor product categories. This hierarchy supports deterministic control alongside sophisticated graphical and communications workloads.
The verified product information identifies the Cortex-M7 core, 216 MHz maximum frequency, 1 MB Flash memory, Art Accelerator, L1 cache, SDRAM capability, and TFT support as defining features. Its 176-pin LQFP package provides a substantial number of external connections compared with smaller microcontroller packages, making it appropriate for systems that need parallel display interfaces, multiple communications peripherals, external memory interfaces, and a broad pin budget.
At the architectural level, the STM32F746IGT6E is intended for high-performance embedded control rather than minimal low-power sensing. The Cortex-M7 processor and FPU support demanding control loops and signal-processing workloads, while the Art Accelerator is relevant to graphical data movement. Exact RAM capacity, voltage ranges, pin assignments, and peripheral operating limits were not included in the supplied verified data and therefore require confirmation in the manufacturer documentation.
Typical uses include industrial human-machine interfaces, TFT-based control panels, industrial automation controllers, communications equipment, and external SDRAM-based graphics terminals. The 216 MHz processing headroom and 176-pin connection count are useful when combining real-time control with display, networking, storage, and sensing functions. System-level qualification remains necessary because peripheral mix, clock configuration, memory organization, and software support must match the intended design.
Designers should verify pin multiplexing, power architecture, decoupling, clock-tree settings, memory routing, and boot configuration against the current STMicroelectronics documentation before layout release. A 176-pin LQFP footprint also requires careful fanout and assembly planning. SWD programming is appropriate for bring-up, while production programming and secure boot should follow the selected programming and security strategy.
This product page consolidates verified distributor availability, manufacturer feature information, same-package replacement candidates, pricing placeholders, and practical design guidance. Because the supplied data omits several electrical and package-specific details, the datasheet and product page remain the controlling sources for production design decisions.

Aplicaciones típicas
STM32F746IGT6E es adecuado para 6 aplicacións: Industrial TFT Human-Machine Interface, Industrial Automation Controller, Communications Equipment, External-SDRAM Graphics Terminal, Robotics Control Platform, Embedded Data Acquisition and Control.
Industrial TFT Human-Machine Interface
The STM32F746IGT6E fits an industrial TFT human-machine interface because its 216 MHz Cortex-M7 core provides real-time control headroom while the Art Accelerator, L1 cache, SDRAM support, and TFT support address graphics-intensive workloads. Its 176-pin LQFP package also offers more external connectivity than a compact MCU, allowing display, touch, communications, and control signals to coexist. The processor can execute display updates alongside deterministic machine-control functions without relying on a separate graphics processor. Before schematic release, verify the exact TFT interface pin multiplexing, SDRAM requirements, display timing, memory bandwidth, and operating-temperature grade in the manufacturer documentation.
Industrial Automation Controller
The STM32F746IGT6E is appropriate for an industrial automation controller that combines real-time I/O control with communication and supervisory functions. Its 216 MHz Arm Cortex-M7 core and floating-point unit provide substantial processing margin for motion calculations, diagnostics, and protocol handling, while 1 MB Flash stores application firmware and supporting logic. The 176-pin LQFP package gives a board designer access to a comparatively broad pin set for sensors, actuators, field buses, and local displays. Use the available package space deliberately because high-speed signals, supply inputs, and external memory require careful pin planning. Final qualification should verify industrial temperature limits, isolation strategy, ESD protection, and long-term supply availability.
Communications Equipment
The STM32F746IGT6E can serve as the main embedded controller in communications equipment where protocol handling, real-time control, external memory, and display or diagnostic functions must share one processor. The 216 MHz Cortex-M7 core and 1 MB Flash capacity provide enough headline performance for demanding control-plane and packet-processing tasks, while SDRAM support can expand working memory when required. Its broad 176-pin package can expose multiple communications interfaces and debug connections. Designers should confirm the selected peripheral instances, electrical characteristics of each interface, clock requirements, protocol timing, and board-level signal integrity against the current datasheet before treating the device as a finalized platform.
External-SDRAM Graphics Terminal
The STM32F746IGT6E is a natural fit for an SDRAM-backed graphics terminal because the verified feature set combines a 216 MHz Cortex-M7 processor, Art Accelerator, L1 cache, SDRAM support, and TFT support. These resources help manage framebuffer movement and display workloads that exceed the practical capability of a basic microcontroller. The 176-pin LQFP package can accommodate the required external-memory and display connections, subject to exact pin multiplexing and speed ratings. A successful layout must preserve matched routing for SDRAM signals, provide clean power and ground distribution, and validate write bandwidth against the selected memory device and framebuffer resolution.
Robotics Control Platform
The STM32F746IGT6E can support a robot or intelligent motion-control platform that combines sensor fusion, control algorithms, communications, and a local graphical interface. Its 216 MHz Cortex-M7 processor and integrated floating-point unit are useful for real-time calculations, while 1 MB Flash provides room for control firmware and communication stacks. The 176-pin package offers a broad pin budget for encoders, motor-control signals, communication peripherals, and an operator display. Because the supplied data does not specify timer features, ADC performance, safety behavior, or temperature limits, those functions must be checked separately. Firmware isolation and deterministic scheduling are important when the display workload shares the processor with a motion-control loop.
Embedded Data Acquisition and Control
The STM32F746IGT6E suits embedded data-acquisition and control products that need local processing, substantial program storage, and an expandable peripheral connection set. A 216 MHz Cortex-M7 core can execute signal conditioning logic, protocol conversion, and supervisory control, while 1 MB Flash supports application code and configuration handling. The 176-pin LQFP package is suitable for systems combining analog front ends, communication links, storage, and status displays. Engineering review should determine the exact ADC, timer, DAC, and communication resources required, because those specifications were not included in the verified excerpts. Isolation, grounding, surge protection, and thermal margins must also be established for the intended installation environment.

Notas de diseño
Verify the exact supply rails, current limits, sequencing requirements, and decoupling values against the current STM32F746IG documentation before schematic release. Place required bulk and high-frequency capacitors close to their associated supply pins, and keep sensitive analog or external-memory supplies on dedicated branches where the device supports them. The verified data does not include input-voltage limits or active-current figures, so a numerical power budget cannot be calculated without adding unsubstantiated assumptions.
Plan the 176-pin LQFP layout with an escape strategy that preserves access to all pins and accommodates assembly inspection. Use short, direct connections for external SDRAM and TFT interfaces, maintain continuous ground planes, and place decoupling near the corresponding pins. Because the canonical SVG library supplied for this task has no LQFP-176 drawing, the package-diagram asset defaults to the generic package image; engineers should not use that generic image for fanout or pin-number verification.
Estimate junction temperature using verified maximum clock, core voltage, peripheral loading, ambient temperature, and package thermal data. Those operating and thermal parameters were not included in the supplied web excerpts, so any arithmetic would be speculative. Before production, assess worst-case activity during sustained computation, SDRAM transfers, and TFT updates, and ensure that PCB copper and thermal vias can keep the device within its manufacturer-defined limits.
Route external-memory and display signals according to the manufacturer's layout guidance, with attention to edge rate, return paths, impedance, and crosstalk. External SDRAM can create high-frequency switching activity, while TFT interfaces may involve numerous parallel signals with tight timing constraints. Validate the final stack-up and routing with signal-integrity analysis if channel lengths or edge rates are aggressive, and keep clocks away from noisy power-conversion nodes.
Do not treat a shared family name or package as proof of drop-in equivalence. Although the listed candidates retain the 216 MHz Cortex-M7 and 1 MB Flash classes in a 176-pin LQFP package, the STM32F745 and STM32F746 lines differ in peripheral and feature availability. Before substitution, compare alternate-function mappings, clock tree, DMA channels, memory interfaces, startup code, low-power behavior, package markings, and qualification. Firmware changes should be included in the validation plan.
