STM32F405OGY6TR - 168MHz Cortex-M4 1MB MCU | STMicroelectronics
MPN： STM32F405OGY6TR ✓ 啟用中STM32F405OGY6TR 概覽
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and communication interfaces into one device. The STM32F4 family belongs to the hierarchy of embedded microcontroller, RISC processor, semiconductor, and connected-control product categories. It combines general-purpose control with DSP-oriented processing and extensive serial connectivity, allowing one device to supervise sensors, motors, communications, data acquisition, and human-machine interfaces.
The supplied family data identifies an Arm Cortex-M4 core with FPU, an ART Accelerator, a memory protection unit, and operation up to 168 MHz. One search result reports 210 DMIPS at 1.25 DMIPS/MHz. The device also provides 1 MB of Flash, 192 KB plus 4 KB of RAM, USB OTG high-speed and full-speed support, Ethernet, 17 timers, three ADCs, and 15 communication interfaces including camera-related connectivity.
Its 90-WLCSP format supports compact assemblies where conventional leaded packages would be difficult to route. The package places a large number of contacts on a small area, so escape routing, via density, assembly capability, inspection, and rework become important manufacturing constraints. The exact electrical limits and pin functions must be checked against the manufacturer datasheet before release because they were not supplied in the verified excerpts.
Typical uses include industrial data acquisition, Ethernet-connected equipment, audio and real-time signal processing, USB peripherals, camera modules, and motor-control platforms. The Cortex-M4F core is useful when an application benefits from floating-point calculations and DSP instructions. Its 168 MHz ceiling provides scheduling margin, although real-time performance still depends on clock configuration, Flash wait states, memory contention, peripheral timing, and firmware design.
A critical design step is decoupling every supported supply rail at its pins and respecting the WLCSP layout rules for exposed contacts and thermal or assembly requirements. Designers should also confirm startup, clock, reset, bootloader, and peripheral assignments in the complete STMicroelectronics documentation rather than inferring behavior from the orderable MPN alone.
This page consolidates the verified manufacturer and distributor facts, separates documented parameters from missing data, and highlights package and sourcing constraints that are not obvious from the MPN alone. It does not infer unverified pricing, pin assignments, compliance claims, or cross-device compatibility.

典型應用
STM32F405OGY6TR 適用於 6 應用s: Industrial Data Acquisition, USB Audio and DSP Control, Ethernet-Connected Control Equipment, Camera and Embedded Vision Module, Motor and Motion Control, Compact Test and Measurement.
Industrial Data Acquisition
The STM32F405OGY6TR fits compact industrial acquisition equipment that must combine fast sampling, control logic, and multiple communications paths. Its Cortex-M4F core operates up to 168 MHz and is rated at 210 DMIPS, while three ADCs and 17 timers provide resources for synchronized measurement and timing. Firmware can use the FPU and DSP instructions for filtering and numeric conversion, reducing CPU overhead compared with simpler control loops. USB OTG and Ethernet support can move data to a host computer or network. The main engineering constraint is the 90-WLCSP layout: ball escape routing, via density, assembly yield, and thermal validation require careful PCB planning. Confirm exact ADC characteristics, supply limits, pin multiplexing, and timing values in the manufacturer documentation before production release.
推薦
USB Audio and DSP Control
The STM32F405OGY6TR is suitable for USB-connected audio and real-time DSP products because it combines a 168 MHz Cortex-M4F core, hardware floating-point unit, DSP instruction support, and USB OTG high-speed or full-speed operation. The core can perform filtering, mixing, transforms, and control calculations while USB handles host or device traffic. The 1 MB Flash provides substantial room for code and constants, while the 192 KB plus 4 KB RAM supports working buffers. Engineers should define the USB clocking, PHY or transceiver arrangement, interrupt priorities, and DMA path before PCB routing. Because the verified excerpts do not provide audio-class support, latency, or USB electrical limits, those details must be confirmed from the exact STMicroelectronics datasheet and reference manual rather than inferred from the MPN.
推薦
Ethernet-Connected Control Equipment
The STM32F405OGY6TR is appropriate for industrial controllers that need deterministic control performance alongside Ethernet connectivity. The Cortex-M4F executes up to 168 MHz, and the verified family information lists Ethernet, USB OTG, numerous timers, and 15 communication interfaces. This allows one MCU to manage local I/O, communications, diagnostics, and control algorithms without relying on a separate high-level processor. The 90-WLCSP package can simplify compact equipment but makes fanout and assembly capability decisive. Use short, controlled Ethernet differential routes, provide the exact PHY and magnetics specified by the reference design, and separate high-current digital paths from sensitive analog sections. Supply-voltage tolerance, transceiver timing, thermal limits, and package-specific layout values are not included in the verified excerpts and must be obtained from the manufacturer documentation.
推薦
Camera and Embedded Vision Module
The STM32F405OGY6TR can serve as the control and interface processor in a compact camera or embedded-vision module. Its Cortex-M4F core provides floating-point and DSP capability for image pre-processing, while the verified feature list explicitly includes camera interfaces and multiple communication peripherals. The 1 MB Flash supports substantial embedded firmware, and the 90-WLCSP footprint helps reduce module size when high-density assembly is available. Designers should budget memory bandwidth and DMA channels carefully, validate frame timing under worst-case processing load, and keep noisy sensor or power-conversion paths away from clocked logic. The supplied data does not state camera-interface lane timing, MIPI support, or supported sensor modes, so it cannot establish that any particular camera is supported without checking the exact STM32F405 datasheet.
推薦
Motor and Motion Control
The STM32F405OGY6TR fits motor and motion-control tasks requiring more computation than a basic timer-only controller. Its 168 MHz Cortex-M4F core, DSP instructions, FPU, 17 timers, and three ADCs support current sampling, transform calculations, speed estimation, and supervisory control. The high-performance core can update multiple control loops while Ethernet or USB provides tuning and diagnostics. Firmware should separate hard real-time control from noncritical work, use deterministic interrupt priorities, and verify timer synchronization and ADC trigger behavior on target hardware. The 90-WLCSP package can reduce board area but demands assembly capability and careful decoupling. Power-stage layout, gate-driver selection, current-sense conditioning, and protection requirements are application-specific; exact limits are not present in the verified excerpts and must come from the manufacturer documentation.
推薦
Compact Test and Measurement
The STM32F405OGY6TR is useful in portable or high-density measurement products where the control core must process samples, manage a display or communications link, and maintain precise timing. Its 210 DMIPS capability, FPU, DSP support, three ADCs, and 17 timers provide a strong processing platform for filtering and calibration. USB OTG can simplify host connectivity, while Ethernet supports remote control and data transfer in laboratory equipment. The 90-WLCSP package is attractive when minimizing board area, but its fine-pitch assembly may increase prototype and rework costs. Route analog inputs away from digital return currents, use the manufacturer's recommended reference layout, and validate trigger jitter, acquisition timing, and thermal behavior on production-representative hardware. ADC resolution, sampling rate, and accuracy were not supplied and must not be inferred.

主要差異化特點
- High-performance Cortex-M4F processing (對比STM32F405OEY6TR)
- Integrated memory and connectivity (對比STM32F405OEY6BTR)
- Compact package integration (對比STM32F405RGT6)
設計說明
The 90-WLCSP requires a deliberate escape-routing strategy. Confirm the exact package ball map and assembly process before committing to layout, use the manufacturer footprint, and route high-speed or sensitive nets with controlled reference paths. Keep via drops, solder-mask clearances, and copper features within the package manufacturer's rules. The supplied excerpts identify the package dimensions but do not provide a ball table or recommended land pattern, so those details must be taken from the exact STMicroelectronics package drawing.
Do not infer supply values or capacitor values from the STM32F405OGY6TR name. Retrieve the electrical characteristics, power-up sequence, decoupling, and power-supply recommendations for the exact STM32F405 package from the manufacturer datasheet and reference manual. Place required bulk and high-frequency capacitors close to their associated supply balls, provide a low-impedance ground reference, and measure startup and transient behavior on a prototype. Unverified voltage and current numbers are intentionally omitted rather than estimated.
For USB, Ethernet, camera, or other high-speed interfaces, use the exact electrical and layout guidance for the selected companion device. Keep clock and data routes short, return current continuous, and isolate high-current switching paths from analog and communication circuits. The verified records confirm USB OTG, Ethernet, camera support, and multiple communication interfaces, but they do not provide rise-time, impedance, timing, or transceiver requirements. Validate these against the relevant controller and transceiver datasheets.
A related MPN is not automatically a drop-in substitute. Confirm the exact ordering suffix, package, pin or ball assignment, electrical limits, temperature grade, flash identifier, and software compatibility before replacing STM32F405OGY6TR. The supplied search results include related STM32 devices but do not establish complete interchangeability. Prototype validation should cover boot, clocks, reset, interrupts, DMA, USB, Ethernet, ADC, timers, and production programming before an engineering change is approved.
