STM32F405OEY6TR Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one system-on-chip. The STM32F405 belongs to the STM32F4 high-performance microcontroller family, combining an Arm Cortex-M4 core with real-time control capabilities, communications peripherals, and low-power design options. Its architecture is suitable for industrial equipment, audio and signal processing, communications, consumer products, and embedded control platforms.
Key features include a 168 MHz maximum operating frequency, single-precision floating-point support, DSP instructions, a memory protection unit, and the ART Accelerator. The verified distributor data identifies 512 KB of Flash memory and a 90-WLCSP package. The Arm Cortex-M4 core also supports a full set of DSP instructions, making the device suitable for applications that combine control logic with numerical signal processing.
The STM32F405OEY6TR is part of the STM32F405xx and STM32F407xx family described in the STMicroelectronics datasheet. Its high-performance architecture is useful when processing speed and deterministic embedded execution matter, while integrated peripherals reduce the need for external components. The exact RAM, voltage, temperature, and peripheral configuration should be confirmed from the complete manufacturer documentation for the selected package and orderable variant.
Typical applications include industrial automation and factory equipment, networked embedded controllers, audio and DSP modules, communications equipment, and consumer electronics. Designers should verify board-level pin availability, power requirements, memory mapping, and startup configuration before production use. The WLCSP format also requires careful PCB layout and assembly capability.
The most important design consideration is to follow STMicroelectronics reference layout, recommended decoupling, exposed-pad thermal requirements, and package-specific assembly guidelines. Firmware should use the STM32CubeMX or STM32CubeIDE-generated startup and peripheral configuration appropriate to the exact device variant. This page consolidates verified distributor data, manufacturer documentation references, application guidance, and replacement limitations for engineering evaluation.

Aplicações típicas
STM32F405OEY6TR é adequado para 6 aplicaçãos: Industrial Automation and Factory Control, Audio and Digital Signal Processing, Communications and Networked Embedded Equipment, Motor and Motion Control, Test and Measurement Instruments, Consumer and IoT Products.
Industrial Automation and Factory Control
The STM32F405OEY6TR fits compact industrial controllers that need responsive control logic and numerical processing on one microcontroller. Its Arm Cortex-M4 core operates up to 168 MHz, includes a single-precision FPU and DSP instructions, and provides 512 KB of Flash for control code and configuration data. The device can manage sensor acquisition, actuator sequencing, communication tasks, and supervisory logic in a compact 90-WLCSP package. Designers should validate electrical limits, peripheral assignments, and factory-control timing against the complete STMicroelectronics datasheet, especially when using long-lived production programs.
Recomendado
Audio and Digital Signal Processing
The STM32F405OEY6TR is suitable for embedded audio and signal-processing modules because its Cortex-M4 core includes single-precision floating-point support and a full set of DSP instructions. At up to 168 MHz, the MCU can combine real-time sampling, filtering, control, and communications tasks while using 512 KB of Flash. The ART Accelerator is identified in the verified family data as supporting zero-wait-state execution from Flash. Actual audio performance still depends on codec interface timing, DMA configuration, memory bandwidth, and the selected audio architecture, so prototype-level timing and signal-quality validation remain necessary.
Recomendado
Communications and Networked Embedded Equipment
STM32F405OEY6TR can serve as the central controller in communications equipment where deterministic embedded execution and peripheral integration are important. The 168 MHz Cortex-M4 core provides computational headroom for protocol processing, packet handling, user-interface control, and supervisory tasks. The 512 KB Flash capacity supports a moderate embedded firmware image, while the compact 90-WLCSP package assists space-constrained designs. Verify the exact USART, USB, Ethernet, timer, and memory-mapped peripheral configuration in the selected STM32F405 variant before finalizing the board.
Recomendado
Motor and Motion Control
The STM32F405OEY6TR is appropriate for compact motor-control and motion-control subsystems that combine high-speed computation with embedded real-time processing. Its Cortex-M4 core operates up to 168 MHz and includes an FPU and DSP instructions, which are useful for control calculations and signal transformation. The device can coordinate timer-based PWM, encoder inputs, communications, and protection logic in one package. Use the exact timer, ADC, DMA, and pin-mux configuration from the manufacturer documentation, and verify current limits, isolation, thermal conditions, and motor-driver requirements outside the MCU.
Recomendado
Test and Measurement Instruments
The STM32F405OEY6TR can be evaluated as the control and processing core of a compact test or measurement instrument. Its 168 MHz Cortex-M4 performance, floating-point unit, and DSP instructions support acquisition control, calibration arithmetic, signal analysis, and front-panel management. The 512 KB Flash store provides room for application firmware, while the 90-WLCSP format supports compact board designs when the assembly process is capable of handling the package. Instrument accuracy is primarily determined by analog front-end design, references, clocking, calibration, isolation, and signal-integrity implementation rather than by CPU frequency alone.
Recomendado
Consumer and IoT Products
STM32F405OEY6TR is suitable for compact consumer devices and IoT endpoints that need more processing capability than a basic microcontroller while retaining integrated memory and control. The 168 MHz Cortex-M4 core, 512 KB Flash, floating-point support, and DSP instructions can handle user-interface logic, sensor fusion, local processing, and communications. The 90-WLCSP package helps reduce board area but requires assembly capability and careful layout. Before production, confirm low-power behavior, clock sources, RF integration, antenna design, security requirements, and the exact peripheral resources of the selected STM32F405 orderable part.

Notas de projeto
Use the official STMicroelectronics package drawing and reference layout for the 90-WLCSP, because the verified distributor description confirms only the 4.22 mm by 3.97 mm package size. Confirm ball pitch, pad geometry, solder-mask clearances, via strategy, and assembly requirements with the PCB manufacturer before release. The compact WLCSP footprint can be electrically and mechanically sensitive to layout and solder-process variations.
Apply the exact power pins, decoupling network, voltage limits, and startup requirements from the complete STM32F405OE manufacturer documentation. Do not infer supply values from the Cortex-M4 core or from related STM32F4 devices. Place required bypass capacitors close to the relevant supply pins, provide a low-impedance ground return, and validate power sequencing and transient behavior with the final board.
Thermal design must include the PCB copper available around the package and the heat generated by the selected clock and peripheral load. The supplied data does not provide verified thermal resistance or power dissipation values for this exact orderable part, so no thermal figure should be estimated from generic STM32F4 data. Measure or calculate the final junction and board temperatures under worst-case operating conditions using manufacturer-approved thermal parameters.
Do not treat a related STM32F4 orderable code as a drop-in substitute without checking the package ball map, pin multiplexing, memory size, voltage limits, temperature grade, clock configuration, peripheral set, and firmware support. The supplied alternatives data identifies related variants but does not prove complete pin-to-pin equivalence. Validate replacement parts against the official datasheet and perform hardware regression testing.
Informações de conformidade
The supplied verified search results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for STM32F405OEY6TR. Obtain current compliance declarations from STMicroelectronics or an authorized distributor.
