STM32F746ZGT6G - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
MPN： STM32F746ZGT6G ✓ 啟用中STM32F746ZGT6G 概覽
A microcontroller is a programmable embedded-system component that combines a processor core, nonvolatile program memory, data memory, peripheral interfaces and control logic on one integrated circuit. The STM32F7 family belongs to the hierarchy microcontroller, embedded processor, 32-bit RISC processor and power-managed semiconductor. It is designed to execute firmware, acquire sensor data, control external circuitry and manage communications while providing substantially more computation than basic 8-bit or 32-bit control devices.
The STM32F746ZGT6G supports operation up to 216 MHz and includes 1 MB of Flash. Its Cortex-M7 core implements Arm single-precision floating-point and DSP instructions, making it suitable for control algorithms involving mathematical transforms, filtering or real-time signal processing. The L1 cache improves instruction and data access efficiency, while the Art Accelerator accelerates graphics-oriented operations involving supported STM32 graphical interfaces.
The STM32F746xx platform provides SDRAM and TFT-LCD capabilities alongside its high-performance CPU core. These characteristics distinguish it from general-purpose microcontrollers intended only for basic control, while retaining the integration advantage of a single-device embedded solution. The exact supply voltage, RAM capacity, operating-temperature limits and individual peripheral configuration must be confirmed against the order-code information and electrical tables in the manufacturer datasheet before design release.
Typical applications include industrial automation controllers, human-machine interfaces, TFT display systems, networked embedded equipment and high-speed signal-processing products. The Art Accelerator and TFT support make the STM32F746 family especially relevant to graphical user interfaces, while the Cortex-M7 DSP and floating-point capabilities support real-time control and signal-processing workloads that exceed the practical demands of entry-level microcontrollers.
PCB design should preserve the exact LQFP-144 footprint, land pattern and exposed thermal and power requirements specified by STMicroelectronics. Firmware and peripheral initialization should use the STM32CubeMX and STM32CubeIDE workflows associated with STM32 devices, but the verified source data does not specify minimum decoupling capacitance, internal regulator settings or detailed GPIO alternate-function mappings.
This page consolidates the verified manufacturer, distributor and cross-reference information for STM32F746ZGT6G, identifies same-family drop-in candidates, and separates confirmed specifications from data that still requires engineering review. It also adds selection guidance and design cautions that are not provided as a single consolidated view in the distributor listings.

典型應用
STM32F746ZGT6G 適用於 6 應用s: Industrial Automation Controller, TFT Human-Machine Interface, Real-Time Signal Processing, Networked Embedded Equipment, Communications Gateway, Data Acquisition and Monitoring.
Industrial Automation Controller
The STM32F746ZGT6G fits industrial automation control because its 216 MHz Cortex-M7 core can execute real-time control logic, communications handling and supervisory firmware in one device. The single-precision floating-point and DSP instruction support is useful when control calculations process sampled sensor data without offloading every operation to an external accelerator. Its L1 cache can improve execution efficiency in interrupt-heavy systems. A practical design places the MCU beside signal-conditioning circuitry and isolated communication transceivers, while preserving clean return paths and a controlled reference plane. The 1 MB Flash capacity provides substantially more program space than many basic control MCUs, although the application team must verify RAM, peripheral mix and temperature grade from the manufacturer datasheet before freezing the design.
推薦
TFT Human-Machine Interface
The STM32F746ZGT6G is well matched to a TFT-based human-machine interface because the verified product listing identifies TFT support, SDRAM capability and an Art Accelerator. The 216 MHz Cortex-M7 core can manage graphical updates, touch-control logic and communications concurrently, reducing the need for a separate display controller. SDRAM can support higher-resolution frame storage when the memory interface and board topology meet the manufacturer's requirements. Designers should verify panel interface timing, external memory configuration and pin multiplexing in the official datasheet, then keep high-speed display traces short and reference a continuous ground plane. This approach is preferable to using a general-purpose low-end MCU when the display must refresh quickly while control and network tasks remain responsive.
推薦
Real-Time Signal Processing
The STM32F746ZGT6G supports real-time signal-processing workloads through its 216 MHz Arm Cortex-M7 core, single-precision floating-point unit and DSP instruction set. These resources allow filters, transforms and control-loop calculations to run locally rather than requiring a separate DSP for every task. The 1 MB Flash supports substantially larger firmware than many entry-level MCUs, which can simplify logging, protocol stacks and control code integration. For deterministic behavior, the design should use suitable RTOS scheduling, peripheral-triggered acquisition and carefully controlled interrupt priorities. Timer channels, ADC performance and memory bandwidth are not fully specified in the supplied data, so engineers must confirm acquisition timing and DMA behavior against the manufacturer datasheet before claiming a particular signal-processing performance level.
推薦
Networked Embedded Equipment
The STM32F746ZGT6G can serve as the application processor in connected industrial equipment because its Cortex-M7 performance leaves headroom for protocol handling, local control and a graphical service interface. Its 1 MB of program Flash provides room for a TCP/IP stack, device drivers and application firmware, while the SDRAM capability can assist with larger network or display buffers. A practical implementation can pair the MCU with a dedicated Ethernet PHY, isolate external interfaces and route high-speed communication signals away from sensitive analog sections. Because the verified data does not enumerate every Ethernet, USB or security peripheral, the engineer must confirm the required MAC, PHY interface, DMA channels and peripheral multiplexing in the official datasheet rather than assuming a specific networking feature is present.
推薦
Communications Gateway
The STM32F746ZGT6G is appropriate for a communications gateway that must combine protocol conversion, local processing and industrial interfaces. Its 216 MHz Cortex-M7 core provides more computation than a basic microcontroller, while DSP and floating-point instructions can accelerate payload transformations. The 1 MB Flash permits integration of multiple protocol stacks and diagnostic firmware in one image. Engineers should allocate independent serial and bus interfaces according to the exact peripheral map, use disciplined pin multiplexing and isolate external transceivers from the MCU's sensitive supply and clock domains. The verified sources do not provide a complete list of available communication peripherals, so final channel-count decisions must be based on the manufacturer datasheet and the selected peripheral configuration rather than on the general STM32F7 family name.
推薦
Data Acquisition and Monitoring
The STM32F746ZGT6G can act as the supervisory controller in a data-acquisition system, combining high-rate peripheral operation with processing, filtering and data formatting. The Cortex-M7's DSP and floating-point capabilities help with scaling, filtering and calibration, while its 1 MB Flash accommodates drivers, acquisition software and communication protocols. A practical system can use the MCU to configure external converters, timestamp events, validate samples and forward results through a network or serial interface. Because the verified data does not specify ADC resolution, sampling rate, trigger performance or DMA channel count, those functions cannot be assumed. Engineers should select acquisition parts based on the verified interface requirements and confirm every timer, DMA and analog-adapter resource in the official datasheet before committing the schematic.

主要差異化特點
- Verified high-performance Cortex-M7 clock rating (對比STM32F745ZGT6)
- Target-specific order code with confirmed distributor availability (對比STM32F746ZGT7)
- Same-package migration within one manufacturer (對比STM32F746ZGT6)
設計說明
Use the STMicroelectronics LQFP-144 land pattern exactly as shown in the official package drawing; do not derive it from a generic 144-pin library. Confirm pin 1 orientation, pad dimensions and solder-mask clearance against the current mechanical drawing. The verified web data confirms the 20 x 20 mm package but does not provide a complete numbered pin table, so schematic-to-footprint comparison should be performed before release.
Separate analog, digital and I/O supply distribution according to the STM32F746 power-supply architecture specified in the manufacturer datasheet. The supplied sources do not provide the exact operating-voltage range, internal-regulator settings, decoupling values or power-consumption figures. Follow the STMicroelectronics recommended application schematic for bypass capacitance and power sequencing rather than substituting generic values.
For TFT and SDRAM implementations, route high-speed memory and display signals over continuous reference planes with short return paths, and place termination or series-resistance components where the STMicroelectronics hardware guidelines prescribe them. Keep switching regulators, crystal circuits and high-speed memory away from precision analog inputs. Pin muxing and signal-integrity limits must be verified because the supplied data does not include edge-rate, capacitance or timing tables.
Do not assume that every STM32F7 order code is an automatic drop-in substitute. Although the family shares the Cortex-M7 platform, suffix codes can affect temperature grade, packaging and environmental qualification, and the STM32F745 and STM32F746 feature sets are not necessarily identical. Compare the complete order codes, pin table, peripherals, clock tree, memory configuration and qualification status before substituting a candidate.
合規資訊
The verified product listings and manufacturer datasheet snippet do not explicitly state compliance status. The final G suffix may relate to environmental ordering information, but its exact meaning must be confirmed from the STMicroelectronics order-code section.
