STM32H743AII6TR Overview
A microcontroller is a programmable embedded-system component that integrates a processor core, memory, peripherals, and communication interfaces on one semiconductor device. STM32H7 devices combine Cortex-M7 processing, direct-memory-access peripherals, hardware acceleration, and extensive serial connectivity for industrial control, communications, audio, and instrumentation systems. This hierarchy places the STM32H743AII6TR within MCU, embedded processor, and semiconductor categories.
Verified distributor data identifies the device as an ARM Cortex-M7 STM32H7 MCU with 32-bit architecture, 480 MHz operation, 2 MB flash organized as 2M x 8, and a 169-UFBGA package measuring 7 x 7 mm. Mouser also identifies 1 MB RAM and the DP-FPU feature set. The high operating frequency and memory capacity make the part suitable for control loops, protocol gateways, data acquisition, and embedded user-interface systems.
The STM32H743AI family uses the high-performance Arm Cortex-M7 RISC core, according to the STMicroelectronics product page. The I/G device family supports operating frequencies up to 480 MHz. Exact peripheral mix, pin names, electrical limits, memory-map details, and package ball assignments should be confirmed against the official STM32H743AI documentation before layout or firmware deployment.
Typical applications include industrial automation, communications equipment, motor and motion control, data-acquisition systems, embedded displays, audio processing, and connected industrial nodes. The 169-UFBGA package is appropriate for compact, multilayer PCB designs, but its fine pitch requires careful fanout, assembly-process control, and thermal-path design.
For a new design, verify the exact STM32H743AII6TR pinout, power sequencing, decoupling requirements, clock tree, memory configuration, and exposed-pad connection in the official datasheet. Use the TR ordering suffix as supplied by the manufacturer only after confirming the associated reel or tray packaging interpretation.
This page consolidates verified distributor pricing, official family information, package identity, and selection guidance for engineers evaluating STM32H743AII6TR. It intentionally does not infer unverified electrical, timing, or compliance values; missing technical details are identified rather than guessed.

Typical Applications
STM32H743AII6TR is suitable for 6 applications: Industrial Automation Controller, Communications Gateway, Motor and Motion Control, Data-Acquisition System, Embedded Audio Processing, Connected Industrial Node.
Industrial Automation Controller
The STM32H743AII6TR fits industrial automation controllers that need fast control-loop execution, substantial firmware storage, and working memory. Its verified 480 MHz Cortex-M7 core, 2 MB of flash, and 1 MB of RAM can support sequencing, communications, diagnostics, and data handling in one device. The MCU can manage sensor acquisition and actuator commands while reserving memory for control algorithms and protocol stacks. Its 169-UFBGA 7 x 7 mm package supports compact control hardware, although fine-pitch assembly and multilayer layout are required. Before deployment, verify industrial temperature limits, EMC performance, isolation needs, and exact peripheral availability in the official documentation.
Recommended
Communications Gateway
The STM32H743AII6TR is well suited to communications gateways that combine protocol conversion, buffering, and real-time monitoring. At up to 480 MHz, the Cortex-M7 core provides substantial processing headroom for packet handling, state machines, and service logic. Its verified 2 MB flash can hold firmware and protocol components, while 1 MB of RAM can support transient packet buffers and data structures. Designers should confirm Ethernet, USB, UART, and other interface availability for the exact STM32H743AI ordering code. Power sequencing, signal integrity, and transceiver selection remain system-level requirements that are not fully specified in the supplied search data.
Recommended
Motor and Motion Control
The STM32H743AII6TR can serve as the control processor in motor and motion-control systems where deterministic computation, PWM, timers, communication, and diagnostic logic must share one platform. The verified 480 MHz Cortex-M7 core and DP-FPU capability are useful for control calculations and signal transformation, while the 1 MB RAM supports state estimation and motion-control data. The exact timer channels, encoder interfaces, analog features, and motor-control peripherals must be confirmed against the official device documentation. Power-stage isolation, gate-driver timing, current sensing, and thermal protection should be designed separately because they are not established by the distributor snippets.
Recommended
Data-Acquisition System
The STM32H743AII6TR is appropriate for high-rate data-acquisition front ends that must sample, filter, timestamp, and transfer measured data. Its 2 MB of flash can store firmware and configuration, while 1 MB of RAM provides space for acquisition buffers and intermediate digital-filter results. The DP-FPU feature identified by Mouser is useful for arithmetic-heavy processing. The design must still validate the actual ADC architecture, sample rate, converter interface, input bandwidth, and trigger resources for the exact part number. Analog isolation, reference stability, grounding, and signal conditioning are as important as MCU processing performance.
Recommended
Embedded Audio Processing
The STM32H743AII6TR can support embedded audio processing because the verified Cortex-M7 implementation includes DP-FPU capability and operates up to 480 MHz. That combination is useful for real-time filtering, mixing, control, and signal analysis when the selected device provides the required audio interfaces. The 2 MB flash and 1 MB RAM provide meaningful code and buffer capacity, but they do not replace a suitable audio codec, amplifier, clocking plan, or DMA architecture. Engineers should verify the exact I2S, SAI, or other audio resources and confirm signal-integrity and latency requirements against the official STM32H743AI documentation.
Recommended
Connected Industrial Node
The STM32H743AII6TR is a strong candidate for a connected industrial node that must run local control, diagnostics, and communications concurrently. The 480 MHz core provides margin for protocol processing, while 2 MB of flash and 1 MB of RAM can support firmware, configuration, and local buffering. A connected node also needs a reliable network interface, secure boot or update strategy, and careful power budgeting. The provided data does not confirm security capabilities or wireless support for this exact ordering code, so those functions must be verified from official STMicroelectronics documentation rather than inferred from the STM32H7 family name.

Design Notes
Treat the 169-UFBGA layout as a high-density assembly design. Confirm ball assignments, power-domain requirements, decoupling locations, clock routing, and exposed-pad treatment from the official package documentation before routing. Use a multilayer PCB and a fabrication/assembly process qualified for the package pitch; do not derive the layout from a different STM32H7 package.
Plan the power tree only after checking the official recommended operating conditions and external-component requirements. The verified data confirms 1.8 V, 2.5 V, and 3.3 V options, but it does not provide startup sequencing or regulator topology. Separate sensitive analog supplies from digital switching paths where applicable, place bulk and local decoupling close to the relevant pins, and verify startup behavior in hardware.
The 480 MHz core and compact 7 x 7 mm package make thermal design dependent on workload, voltage, ambient temperature, and PCB copper. The supplied data does not provide junction-temperature or thermal-resistance values, so calculate junction temperature from the official electrical limits and package thermal model. Preserve the package thermal path and avoid enclosing the assembly without a validated thermal solution.
Do not assume that another STM32H743AI order code is automatically interchangeable. The verified search results distinguish STM32H743AII6TR, STM32H743AII6, and STM32H743AGI6, but package suffixes, ball assignments, memory options, temperature grades, and packing arrangements must be checked in the manufacturer ordering table. Validate firmware, boot configuration, clocking, and peripheral resources together.
Compliance Information
The supplied search data does not provide compliance declarations for this exact order code. These fields remain unknown rather than inferred from the manufacturer or package family.
