STM32F746BGT7 - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
부품 번호: STM32F746BGT7 ✓ 활성STM32F746BGT7 개요
A microcontroller is a programmable system-on-chip that integrates a CPU core, Flash program memory, SRAM, peripherals, and communication interfaces into one package. The STM32F7 family belongs to the Arm Cortex-M processor hierarchy and is designed for applications requiring substantially more processing capability than typical entry-level microcontrollers. Its cache architecture and DSP support are especially useful for audio, graphics, communications, control, and real-time signal-processing systems.
The STM32F746BGT7 provides 1 MB of Flash for firmware and data, while its Arm Cortex-M7 core supports single-precision floating-point instructions and a full set of DSP instructions. The 216 MHz maximum operating frequency provides additional compute headroom for control algorithms, protocol handling, and user-interface logic. The integrated Art Accelerator accelerates supported graphics operations without relying entirely on the CPU.
STMicroelectronics groups the STM32F746BGT7 with the STM32F745xx and STM32F746xx devices, which are based on the same high-performance Arm Cortex-M7 architecture. The exact SRAM capacity, voltage limits, peripheral configuration, GPIO count, package dimensions beyond the verified 28 mm × 28 mm designation, and operating-temperature limits must be confirmed in the official STM32F745xx and STM32F746xx datasheet for the selected orderable suffix.
Typical uses include industrial human-machine interfaces, TFT display controllers, audio processing, communications equipment, embedded graphics, and high-complexity real-time control. The Cortex-M7 DSP and floating-point capabilities make the MCU suitable for filtering, control, and signal-processing workloads that would burden a smaller microcontroller core.
Designers should preserve the package pin assignments, validate clock and memory configuration against the reference manual, and verify decoupling and signal-integrity requirements in the datasheet. Software migration between STM32F7 devices must also account for differences in the T7 suffix, peripheral set, and device identification rather than assuming every orderable suffix is interchangeable.
This product page consolidates verified manufacturer specifications, current distributor pricing, same-family drop-in candidates, package constraints, and practical engineering guidance. It provides additional selection context for engineers comparing the STM32F746BGT7 with other STM32F7 devices without presenting unverified electrical values as established specifications.

Industrial TFT Human-Machine Interface
The STM32F746BGT7 fits an industrial TFT interface because it combines a 216 MHz Arm Cortex-M7 core with Art Accelerator and TFT controller capability. The CPU can manage touch input, graphics composition, communications, and supervisory logic while the accelerator handles supported graphics operations. Its 1 MB of Flash provides substantial firmware storage for graphics assets, diagnostics, and interface code. The device is placed between the display interface and application peripherals, with system designers expected to configure the controller for the selected panel and external-memory arrangement. Compared with a lower-performance MCU, this part offers more processing and graphics headroom, but exact display timing, memory voltage, and peripheral assignments require review of the official STMicroelectronics datasheet.
추천
Audio DSP and Signal Processing
The STM32F746BGT7 is appropriate for real-time audio processing because its Cortex-M7 core supports single-precision floating-point and DSP instructions at up to 216 MHz. These capabilities suit filtering, mixing, equalization, modulation, and control tasks that benefit from dedicated arithmetic instructions. The MCU can process audio samples while managing DMA movement and configuration interfaces, reducing the need for a separate DSP in cost-sensitive embedded designs. The 1 MB Flash capacity can hold substantial control code and parameter tables. Its trade-off is that software and memory architecture must be designed carefully to avoid cache or DMA contention, and the exact audio peripherals and sample-rate limits must be confirmed in the manufacturer documentation.
추천
Industrial Automation Controller
The STM32F746BGT7 suits industrial automation controllers that combine real-time control with communications and operator-facing functions. Its 216 MHz Cortex-M7 performance provides headroom for control-loop execution, protocol stacks, data logging, and diagnostic algorithms, while the DSP and floating-point instructions assist with sensor conditioning and mathematical processing. The MCU can coordinate inputs, actuator outputs, and local communications through its verified peripheral set, subject to the exact device matrix. The 1 MB Flash capacity supports larger embedded applications and field-upgrade logic. Engineers should partition real-time tasks carefully, validate industrial temperature and voltage requirements for the selected suffix, and confirm the complete pin and peripheral configuration before production release.
추천
Ethernet-Connected Embedded Equipment
The STM32F746BGT7 can serve as the control processor in Ethernet-connected embedded equipment where high-performance firmware execution and external connectivity must coexist. The 216 MHz Cortex-M7 core can handle network supervision, application logic, data preparation, and a user interface while an external Ethernet controller manages the physical network interface. This division of responsibility lets the MCU avoid implementing lower-level network functions in software. The 1 MB Flash capacity provides room for networking, control, and diagnostics code. A practical design must verify the selected STM32F7 device supports the intended camera, communications, and memory peripherals, while the Ethernet PHY and signal-integrity layout are validated independently according to their own documentation.
추천
Secure Communications and Protocol Gateway
The STM32F746BGT7 is suitable for protocol-conversion and communications gateway designs because its Cortex-M7 performance leaves processing headroom for framing, buffering, encryption-related workloads, and multiple serial interfaces. The single-precision FPU and DSP instructions can accelerate payload transformations and filtering, while 1 MB of Flash supports larger protocol stacks and configuration data. The MCU can bridge local industrial buses to an Ethernet or serial uplink while collecting status information for diagnostics. Designers should confirm the exact communications peripherals, memory interface, and package assignments for the selected suffix, and should separate deterministic data paths from non-real-time logging. The official datasheet and reference manual remain the controlling sources for peripheral multiplexing and electrical limits.
추천
High-Performance Embedded User Interface
The STM32F746BGT7 fits advanced embedded user-interface designs that combine a display, touch sensing, communication, and local control. Its 216 MHz Cortex-M7 core can execute responsive application logic, and the verified Art Accelerator and TFT capability support graphics-oriented workloads. The 1 MB Flash storage accommodates interface code, fonts, images, and configuration data, reducing the need for external storage in simpler systems. Engineers can place the MCU at the center of the UI architecture, using DMA for display data movement and dedicated peripherals for communication. The design must still verify panel-interface requirements, external memory needs, pin multiplexing, and startup sequencing in the exact device documentation. If the UI exceeds internal Flash or graphics-memory limits, an external storage component can be added without changing the processor class.

설계 노트
Use the official STMicroelectronics 208-LQFP land pattern and pin table without reconstructing dimensions from generic LQFP drawings. The verified data confirms the 28 mm × 28 mm body but does not include the lead span, exposed thermal information, or complete terminal assignments. Cross-check all power and ground pins against the selected device matrix before routing because unused or differently connected supply terminals can affect signal integrity, startup behavior, and electromagnetic compatibility.
Design the supply network from the exact STM32F746BGT7 electrical-characteristic table rather than generic STM32 guidance. Verify operating voltage limits, regulator tolerance, startup current, and current required by the 216 MHz operating mode. Place required decoupling capacitors at the relevant device pins using the shortest return path, provide bulk energy storage near the load, and avoid routing high-current display, communications, or external-memory paths through sensitive processor supply pins.
External SDRAM, TFT, Ethernet, and high-speed communication paths require deliberate topology and return-path planning. Match trace lengths where the selected peripheral and memory interface specify a relationship, provide continuous reference planes beneath high-speed routes, and keep switching paths away from precision analog inputs. The verified data confirms SDRAM and TFT capability but does not provide timing or routing values, so use the official STM32F7 reference manual and relevant interface specifications for the final constraints.
Do not treat same-family ordering suffixes as automatically interchangeable. Before substituting STM32F746BGT6, STM32F745BGT7, STM32F745BGT6, STM32F743BGT7, or STM32F745VG, compare the exact temperature grade, frequency grade, peripheral matrix, memory configuration, pin availability, and lifecycle status. Also verify that the software initialization sequence and clock settings match the chosen device. A mechanically compatible package alone does not prove electrical or functional drop-in compatibility.
규정 준수 정보
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for STM32F746BGT7. These values remain unknown rather than being inferred from the manufacturer or package family.
