STM32F746NGH6E - 216MHz Cortex-M7 1MB MCU | STMicroelectronics
Référence : STM32F746NGH6E ✓ ActifSTM32F746NGH6E Présentation
A microcontroller is a programmable semiconductor device that integrates a processor core, memory, and peripherals into one component. The STM32F746 product hierarchy extends from the STM32F7 family to the STM32F746 device, the Arm Cortex-M7 core, and the broader category of embedded-system controllers. The Cortex-M7 architecture provides a 32-bit RISC platform for real-time control, while the STM32F746NGH6E combines that processing capability with 1 MB of on-chip flash for firmware storage.
The principal verified specifications are a maximum operating frequency of 216 MHz, 1 MB of flash memory, 32-bit Arm Cortex-M7 architecture, and a 216-TFBGA package. The E suffix distinguishes this ordering code from STM32F746NGH6, but the supplied excerpts do not provide a verified explanation of all grade, temperature, or qualification differences. Consequently, engineers should consult the manufacturer ordering-information section before treating the two order codes as interchangeable production alternatives.
The 216 MHz Cortex-M7 core is suitable for work involving multiple concurrent control tasks, communications, data acquisition, and graphical or industrial user interfaces. Its integrated-peripheral ecosystem can reduce the need for separate interface devices when the selected board design uses the appropriate STM32F7 ecosystem components. Designers must still verify peripheral availability, pin multiplexing, memory requirements, and electrical constraints for their exact design.
Typical applications include industrial automation controllers, human-machine interfaces, networked embedded equipment, audio and multimedia control, and connected sensors. An HMI can use the Cortex-M7 performance to manage display updates and input handling, while an industrial controller can divide time among acquisition, communication, and real-time control tasks. Ethernet-capable communications designs may also pair this MCU with a dedicated physical-layer transceiver.
The principal design consideration is the 216-TFBGA package. Its fine-pitch ball layout requires capable PCB assembly and inspection processes, careful escape routing, and adequate thermal design. The provided sources do not expose the complete 216-ball pinout, so the pin assignment must be verified directly in the manufacturer documentation before schematic capture or PCB layout.
This product page consolidates verified distributor listings, the manufacturer family page, package identity, procurement links, and explicitly identified data gaps. It also distinguishes verified drop-in evidence from broader MCU alternatives that require firmware, electrical, and package validation before substitution.

Applications typiques
STM32F746NGH6E convient pour 6 applications: Industrial Automation Controller, Human-Machine Interface Controller, Networked Embedded Equipment, Data-Acquisition and Control System, Connected Sensor Gateway, Audio and Multimedia Controller.
Industrial Automation Controller
The STM32F746NGH6E fits industrial automation controllers that combine real-time monitoring, communications, and local control in one high-performance embedded platform. Its Arm Cortex-M7 core operates at up to 216 MHz, providing substantial instruction throughput for coordinating sensors, actuators, and operator commands without relying on a separate processor. The 1 MB flash capacity offers room for application firmware, drivers, and configuration data. Because the MCU is supplied in a 216-TFBGA package, the controller board should be routed with fine-pitch BGA design rules and conservative thermal copper distribution. Firmware engineers should use the Cortex-M7 performance to separate acquisition, communication, and control tasks, while maintaining deterministic interrupt and peripheral scheduling.
Human-Machine Interface Controller
The STM32F746NGH6E is suitable for a human-machine interface controller because its Cortex-M7 processor can operate at up to 216 MHz while handling display updates, touch or keypad input, and supervisory logic. The 1 MB of embedded flash provides space for interface firmware and graphical resources, although larger asset sets may require external nonvolatile memory. A typical implementation would place the MCU between the display interface and communications circuitry, with the MCU updating indicators and validating user commands. The 216-TFBGA package minimizes board area but requires assembly capability for fine-pitch balls. Layout planning should provide short display and input traces, clean references, and a thermal design that avoids concentrating heat around the MCU.
Networked Embedded Equipment
The STM32F746NGH6E can serve as the control processor in networked embedded equipment when an application needs more compute headroom than a basic Cortex-M microcontroller. Its 216 MHz Cortex-M7 core can manage protocol processing, local control loops, data buffering, and a user-facing control interface. The 1 MB flash stores application code and network firmware, while RAM availability must be confirmed in the complete manufacturer documentation before sizing buffers. If the design uses Ethernet, the MCU's integrated Ethernet capability and external physical-layer requirements must be verified against the official datasheet. The fine-pitch 216-TFBGA package should be placed to minimize sensitive communication traces and support controlled return paths.
Recommandé
Data-Acquisition and Control System
The STM32F746NGH6E fits data-acquisition systems that need to sample multiple channels, condition incoming data, and retain deterministic control behavior. The 216 MHz Cortex-M7 core provides headroom for concurrent acquisition and communication tasks, while the STM32F746 family targets high-performance embedded designs. The verified 1 MB flash supports firmware storage, but engineers must confirm the device's RAM capacity before selecting buffer sizes. The MCU can coordinate converters, digital sensors, and local storage, provided each selected peripheral is mapped to an available pin and supported by the relevant firmware package. In a mixed-signal board, place the MCU away from high-current switching paths and provide local decoupling according to the complete reference schematic.
Connected Sensor Gateway
The STM32F746NGH6E can act as the processing gateway between local sensors and a wider communications network. Its Cortex-M7 core operating at up to 216 MHz can handle protocol conversion, sensor filtering, event handling, and local diagnostics, while 1 MB of flash accommodates gateway firmware and network services. A practical design would use the MCU to aggregate readings, apply application-specific thresholds, and forward selected data through a communications interface. The 216-TFBGA package helps preserve board area in compact gateways, but assembly yield and rework capability should be considered before committing to the footprint. Firmware should include watchdog and communication recovery behavior so an isolated peripheral fault does not stop the gateway's supervisory function.
Audio and Multimedia Controller
The STM32F746NGH6E is applicable to audio or multimedia control systems that require more real-time processing capability than a low-end Cortex-M device. The 216 MHz Cortex-M7 core can manage control logic, buffer transfers, user commands, and communication with external codecs or display peripherals, while the 1 MB flash stores application firmware. The MCU does not itself establish the final audio signal path; codec selection, clocking, supported audio interfaces, and analog routing must be verified from the complete datasheet. Its 216-TFBGA package offers a compact solution but demands careful ball-out routing for high-speed interface signals. Validate clock jitter, impedance-controlled routes, grounding, and decoupling to prevent digital activity from degrading signal quality.

- Identical verified memory configuration (vs STM32F746NGH6)
Notes de conception
The STM32F746NGH6E uses a 216-TFBGA package, so PCB fabrication and assembly must support its fine-pitch ball geometry and the selected board's escape-routing strategy. Verify the official land pattern, pad dimensions, solder-mask definition, and assembly process rather than deriving geometry from another STM32F7 package. Confirm that the selected assembly house can inspect all 216 balls and that X-ray or equivalent process capability is available for hidden-joint inspection.
Follow the STM32F746 reference schematic and power-supply requirements when planning decoupling, bulk capacitance, and voltage rails. The supplied excerpts do not state the operating-voltage range or exact pinout, so capacitor voltage ratings and connection points must come from the complete manufacturer documentation. Keep the MCU's supply and ground-return paths short, provide local high-frequency bypass capacitance at the relevant supply pins, and isolate switching-regulator nodes from sensitive analog and communication circuitry.
Plan thermal performance around the 216-TFBGA package even though no verified junction-temperature or thermal-resistance data were supplied. Use the official electrical and thermal data to calculate worst-case dissipation across input voltage, output activity, and ambient temperature. Provide uninterrupted ground-plane connectivity beneath and around the BGA, distribute high-current returns through multiple power and ground balls, and model the assembled PCB rather than relying on package dimensions alone.
Do not treat a shared package name as proof that every STM32F746 ordering code is production-equivalent. The STM32F746NGH6 candidate matches the verified core, frequency, flash, and package, but the supplied material does not explain the final E suffix. Before substitution, compare ordering tables for temperature grade, qualification, pin availability, and lifecycle restrictions. Also verify the complete 216-ball pin map; no reliable individual signal assignment was available in the supplied excerpts.
Informations de conformité
The supplied excerpts do not explicitly state the compliance status of STM32F746NGH6E. A comparison-page excerpt mentions RoHS and REACH topics for related order codes, but it does not provide their actual values and therefore cannot establish compliance.
