STM32F746ZGT6E - 216MHz Cortex-M7 MCU | STMicroelectronics
MPN： STM32F746ZGT6E ✓ 啟用中STM32F746ZGT6E 概覽
An ARM Cortex-M7 microcontroller is a 32-bit RISC embedded processor that belongs to the microcontroller and embedded-control hierarchy. Compared with simpler Cortex-M devices, the Cortex-M7 architecture is designed for higher clock rates, caches, accelerated memory access, and DSP-oriented workloads. Within the STM32F7 family, the STM32F746 series combines this processor class with extensive connectivity, graphics support, and external-memory interfaces for demanding control applications.
Verified product information identifies a maximum operating frequency of 216 MHz, 1 MB of flash, an ARM Cortex-M7 core, and a 144-LQFP package. The manufacturer also identifies the STM32F745xx and STM32F746xx families as high-performance Cortex-M7 devices operating up to 216 MHz. Distributor listings further associate the STM32F746 family with an FPU, cache, SDRAM capability, TFT support, and hardware acceleration, although complete electrical limits and interface details must be confirmed in the official product documentation.
The combination of a high clock rate and cache-oriented Cortex-M7 architecture benefits computationally intensive loops in motor control, communications, signal processing, and user-interface logic. The 144-pin package supports systems requiring more external interfaces than smaller STM32 devices, while LQFP construction provides inspectable leads for prototype assembly and conventional manufacturing. Internal 1 MB flash provides local firmware storage, but external SDRAM or storage may still be needed for large frame buffers, data logs, or complex graphics assets.
Typical applications include industrial controllers, factory automation nodes, motor-drive supervisory systems, networked embedded equipment, audio and DSP modules, and human-machine interfaces. The STM32F746ZGT6E can serve as the central controller in these systems while managing communications, real-time control, and human-machine interface tasks. Its exact peripheral mix, memory interfaces, voltage range, and timer capabilities should be checked against the manufacturer documentation before schematic capture.
A key design consideration is package and firmware compatibility. The LQFP-144 footprint requires a land pattern matching the 20 x 20 mm body and its specified lead geometry. Designers should also confirm boot configuration, clock-tree requirements, decoupling, and every peripheral pin before layout release. The manufacturer product page and datasheet should be used to validate all pin assignments and electrical constraints rather than relying on distributor summaries.
This product page consolidates verified manufacturer and distributor information, package details, procurement data, and application guidance into one engineering reference. It also distinguishes verified facts from parameters requiring confirmation, helping designers select the MCU while avoiding assumptions about pinout, memory, lifecycle, or electrical limits.

典型應用
STM32F746ZGT6E 適用於 6 應用s: Industrial Automation Controller, TFT Human-Machine Interface, Motor-Control Supervisory System, Audio and DSP Processing Module, Ethernet-Connected Embedded Gateway, Secure Equipment and Data Logger.
Industrial Automation Controller
The STM32F746ZGT6E fits industrial automation controllers that combine deterministic control with communications and graphical diagnostics. Its verified 216 MHz ARM Cortex-M7 core, FPU, DSP capability, and cache support allow control algorithms and protocol handling to coexist more effectively than on a basic microcontroller. The 144-LQFP package provides a large pin count for digital I/O, communication interfaces, analog inputs, and external storage connections. Designers can place the MCU at the center of a factory equipment controller, using external SDRAM for logs or operating data and an optional TFT interface for diagnostics. The main engineering trade-off is the relatively large LQFP footprint and higher unit cost, offset by simpler firmware partitioning and less reliance on external processors.
推薦
TFT Human-Machine Interface
The STM32F746ZGT6E is suitable for TFT human-machine interfaces because verified distributor data identifies TFT support, SDRAM capability, and hardware acceleration in the STM32F746 family. Its 216 MHz Cortex-M7 core can update a graphical display while maintaining control tasks, while external SDRAM can provide the larger frame buffer required by color graphics. The 144-LQFP package offers enough pins for a display interface, touch-control signals, communications, and power management without forcing a separate graphics processor in simpler equipment. Design teams must still verify the supported display modes, timing, color formats, memory requirements, and panel electrical characteristics in the manufacturer documentation before finalizing the display subsystem.
推薦
Motor-Control Supervisory System
The STM32F746ZGT6E can serve as the supervisory controller in an industrial motor-drive system where real-time computation, communications, and diagnostics must share one MCU. The verified 216 MHz ARM Cortex-M7 core, FPU, and DSP capability are useful for calculating control quantities, monitoring current and position data, and implementing fault-handling logic above the power stage. The large LQFP-144 package supports encoders, communication transceivers, control outputs, and external memory more conveniently than a low-pin-count device. It does not replace a dedicated gate driver or power converter, but it can coordinate them. Safe design practice requires checking timer channels, encoder interfaces, analog inputs, isolation requirements, and the device's exact electrical limits in the official documentation.
推薦
Audio and DSP Processing Module
The STM32F746ZGT6E fits embedded audio and DSP modules that benefit from a high-performance Cortex-M7 core with FPU and DSP support. At up to 216 MHz, the processor can perform real-time filtering, mixing, modulation, or control alongside network and user-interface tasks, while cache support helps manage instruction and data flow. The 144-LQFP package exposes enough pins for audio codecs, control signals, communications, and external storage while retaining a straightforward prototype assembly option. The MCU does not itself reproduce or amplify audio, so codec and output-stage selection remains application-specific. Validate supported audio peripherals, DMA behavior, memory bandwidth, clock configuration, and package-specific pin assignments before releasing a production schematic.
推薦
Ethernet-Connected Embedded Gateway
The STM32F746ZGT6E is appropriate for an Ethernet-connected embedded gateway that needs more processing capacity than a low-end communications MCU. Its verified 216 MHz Cortex-M7 core can manage protocol stacks, local control, data transformation, and diagnostics, while the 144-pin package provides ample connections for Ethernet, storage, serial links, and status controls. An external PHY such as the listed LAN8742A-CZ can provide the physical network interface while the MCU handles the higher layers. For applications requiring sustained data movement, external SDRAM and careful PCB signal integrity become important. Firmware and security requirements must also be evaluated separately because the supplied excerpts do not verify boot features, cryptographic capabilities, or exact peripheral availability.
推薦
Secure Equipment and Data Logger
The STM32F746ZGT6E can serve as the main processor in an equipment controller that records operating data and coordinates multiple serial interfaces. Its 1 MB flash provides local firmware storage, while the STM32F746 family's verified SDRAM capability can support larger working buffers than the internal memory alone. The 144-LQFP package allows connection of storage media, communications modules, sensors, and local operator interfaces in one controller. A practical design should separate critical real-time tasks from logging and service updates, use brownout and clock-reset recovery correctly, and provide sufficient decoupling around the supply pins. Exact RAM capacity, write endurance expectations, boot behavior, security features, and operating limits must be confirmed in the manufacturer documentation before architecture approval.

設計說明
Use the exact 144-LQFP 20 x 20 mm land pattern from the manufacturer package drawing. Preserve the specified 0.5 mm lead pitch and 1.4 mm body-height information identified in the verified listing. Place decoupling capacitors at the supply pins, provide a low-impedance ground plane, and route high-speed memory and display interfaces away from noisy switching nodes. Do not derive the footprint from the generic LQFP name alone because pad length, span, and exposed thermal or mechanical details must follow the exact ST package drawing.
External SDRAM and TFT interfaces require controlled-impedance routing, short point-to-point connections, and continuous reference planes where the manufacturer interface guidance requires them. Avoid splitting the ground plane beneath high-speed pairs, and place termination or compensation only where the signal-integrity analysis and ST interface specification call for it. Because clock, data, and control pins are not available in the supplied excerpts, perform a complete pin assignment and timing review using the official STM32F746ZG documentation before schematic release.
Do not treat STM32F746ZGT6, STM32F746ZGT6E, and related grade suffixes as interchangeable without reviewing STMicroelectronics ordering information. The verified excerpts confirm the 216 MHz Cortex-M7 family, 1 MB flash listing, and LQFP-144 mechanical format, but they do not define every suffix-controlled temperature, qualification, or lifecycle attribute. Likewise, do not assume that an LQFP-144 footprint alone proves drop-in compatibility; verify pin multiplexing, supply requirements, boot configuration, exposed pad requirements, and firmware support for the exact replacement MPN.
Plan the power tree only after confirming the exact STM32F746ZGT6E operating-voltage and current limits from the official datasheet. Separate analog and digital supplies where the device and board architecture permit it, keep switching-regulator layouts compact, and provide local high-frequency bypass at the MCU. If SDRAM or a TFT interface is fitted, account for the additional load during startup and transient operation. Estimated power cannot be provided from the verified excerpts because supply voltage, current, and activity data are missing.
合規資訊
The verified excerpts do not contain explicit compliance declarations for the exact STM32F746ZGT6E ordering code. RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status must be confirmed from the manufacturer product documentation or current supplier declarations.
