STM32F746ZGY6TR - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
Référence : STM32F746ZGY6TR ✓ ActifSTM32F746ZGY6TR Présentation
A microcontroller is a programmable system-on-chip that integrates a processor core, nonvolatile program memory, data memory, peripherals, and communication interfaces on one die. The STM32F7 family belongs to the embedded-processing hierarchy of Arm Cortex-M microcontrollers, combining real-time control capability with higher performance than entry-level Cortex-M devices. Its single-precision floating-point unit supports industrial, communications, audio, and graphics-oriented signal processing.
The STM32F746ZGY6TR operates at up to 216 MHz and includes 1 MB of flash, a single-precision FPU, a complete DSP instruction set, and memory-protection features. These characteristics distinguish it from simpler 8- or 16-bit controllers used for basic appliance control. Its processing capacity supports complex protocol stacks, real-time control loops, and data processing without requiring a separate digital signal processor.
The Arm Cortex-M7 core uses a high-performance 32-bit RISC architecture with single-precision floating-point support. This allows efficient execution of control algorithms and audio or communications workloads while retaining deterministic embedded-system operation. Because the MCU integrates the processor and peripherals into one package, designers can reduce board area and simplify the power-supply architecture compared with a discrete processor and companion devices.
Typical applications include industrial automation equipment, networked controllers, audio and digital signal-processing systems, human-interface platforms, and connected embedded products. The 143-UFBGA package is particularly useful when board area is constrained, although its fine pitch requires careful PCB layout, inspection, and assembly planning. The STM32F746 family is also suitable for high-speed connectivity, industrial communication, and embedded control applications.
When assigning PCB connections, use the complete 143-pin description and package drawing in the STMicroelectronics STM32F745xx/STM32F746xx datasheet. Place decoupling capacitors at every supply pin, route sensitive interfaces away from high-speed switching nodes, and confirm the device's exact power, clock, reset, and I/O limits before finalizing the schematic and layout.
This page combines the manufacturer data with engineering-focused selection guidance, package considerations, interface-role comparisons, and practical design notes. These resources help engineers assess STM32F746ZGY6TR for high-performance embedded designs without relying only on a distributor specification summary.

Applications typiques
STM32F746ZGY6TR convient pour 6 applications: Industrial Automation Controller, Industrial Ethernet Equipment, Audio Signal Processing, Communications Controller, Connected Sensor Hub, Human-Machine Interface Controller.
Industrial Automation Controller
The STM32F746ZGY6TR fits industrial automation controllers that combine real-time machine control with higher-level signal processing. Its Cortex-M7 core operates at up to 216 MHz, while the single-precision FPU and DSP instructions accelerate control calculations without requiring a separate processor. The 1 MB flash provides room for substantial application firmware. Placed on a compact controller board, the MCU can manage sensors, actuators, communications, and safety monitoring. The 143-UFBGA package reduces footprint but requires fine-pitch layout expertise, robust decoupling, and assembly processes capable of handling its 143-ball land pattern.
Recommandé
Industrial Ethernet Equipment
The STM32F746ZGY6TR is suitable for protocol-intensive industrial Ethernet equipment because its 216 MHz Cortex-M7 core provides substantially more compute headroom than entry-level microcontrollers. The single-precision FPU assists with packet handling, measurement mathematics, and real-time control, while 1 MB of flash supports networking stacks and application firmware. The MCU can operate beside an Ethernet transceiver and interface with sensors or actuators. Board partitioning is critical: maintain a continuous ground reference, place interface termination close to the transceiver, and separate high-speed communication traces from precision analog paths.
Recommandé
Audio Signal Processing
The STM32F746ZGY6TR aligns with audio processing because the Cortex-M7 core includes single-precision floating-point hardware and a dedicated DSP instruction set. Running at up to 216 MHz, it can combine real-time filtering, mixing, decoding, and system control while retaining the simplicity of a single-chip embedded architecture. The 1 MB flash supports substantial control code and audio data. In a soundbar, amplifier controller, or digital audio source, decoupling must be concentrated around each supply ball, and analog input routing should avoid digital switching paths to prevent audio noise coupling.
Recommandé
Communications Controller
The STM32F746ZGY6TR is appropriate for communications equipment requiring a 32-bit RISC core, 216 MHz performance, and 1 MB of embedded flash. Protocol processing, framing, buffering, and user-interface tasks can share one MCU, reducing component count on compact gateways or control panels. The DSP instruction set benefits signal-oriented workloads, while the single-precision FPU accelerates transform and filtering operations. Layout should provide short return paths for high-speed interfaces, independent filtering for each supply rail, and controlled impedance routing wherever the board uses communications links above the MCU’s low-speed GPIO and peripheral interfaces.
Recommandé
Connected Sensor Hub
The STM32F746ZGY6TR works well as the processing center of a connected sensor hub because it combines 216 MHz Cortex-M7 performance with 1 MB of flash in a compact 143-UFBGA package. It can aggregate sensor readings, execute filtering, maintain a network connection, and format data for downstream systems. The FPU and DSP instructions are useful for sensor fusion and digital signal conditioning. Keep analog sensor inputs physically separated from the MCU ball field, provide local grounding and bypass capacitors, and verify the power-supply sequencing requirements in the manufacturer datasheet before releasing production artwork.
Recommandé
Human-Machine Interface Controller
The STM32F746ZGY6TR can serve as a human-machine interface controller because its high-performance core manages graphics data movement, touch processing, communications, and application logic concurrently. The 216 MHz operating rate and DSP capability improve responsiveness when the interface combines display updates with real-time controls, while 1 MB of flash supports substantial firmware. In a compact panel or embedded operator terminal, the 143-UFBGA footprint helps limit board area. Use short, properly referenced display and touch-interface routes, isolate noisy switching supplies, and inspect all fine-pitch balls for assembly defects before functional testing.

Notes de conception
Use the exact 143-UFBGA land pattern and pin assignment from the STMicroelectronics DM00166116 datasheet rather than a generic UFBGA footprint. Treat each supply ball as a separate connection, place the required bypass capacitors directly beside the associated pins, and preserve short, low-impedance ground returns. The fine ball pitch makes inspection, solder-paste control, reflow-profile qualification, and PCB warpage management important production considerations.
Follow the exact power-supply, decoupling, and internal-regulator configuration specified in the DM00166116 datasheet. Provide stable supply rails within the 1.8 V to 3.3 V operating range and account for separate core and I/O voltage requirements where applicable. Place bulk and high-frequency decoupling near the device, avoid shared narrow supply paths between the MCU and noisy peripherals, and verify startup, brownout, and power-sequencing behavior before final system timing is frozen.
Keep the Cortex-M7 clock and high-speed memory interface routing short, with continuous reference planes and no unnecessary vias or splits beneath the device. Separate sensitive analog inputs from switching nodes and communication routes, and route high-current outputs independently from precision signal paths. Do not infer that unused balls can be connected or left floating without checking the package pin table, NC classifications, and specific device configuration requirements in the manufacturer documentation.
Do not treat another STM32F746 ordering code as an automatic replacement. Device suffixes can change package type, pin count, flash size, temperature grade, and supported peripherals. A valid replacement must match the 143-UFBGA land pattern and ball assignment while also meeting the board’s electrical and firmware requirements. Before substitution, compare the complete pin tables, power architecture, clock tree, peripheral assignments, boot behavior, and package drawings for both exact MPNs.
