STM32F405OEY6BTR - 168MHz Cortex-M4 MCU | STMicroelectronics
MPN： STM32F405OEY6BTR ✓ 啟用中STM32F405OEY6BTR 概覽
A microcontroller is a programmable system-on-chip that integrates a CPU core, memory, communication interfaces, timers, and control peripherals. The STM32F405OE belongs to the STM32F4 high-performance embedded family, where the Cortex-M4 core executes control logic while DMA and hardware peripherals move data with limited CPU intervention. This hierarchy places the device between a basic processor and a complete embedded control platform.
Verified features include a 32-bit Arm Cortex-M4 processor, an FPU, DSP instructions, 210 DMIPS, adaptive real-time acceleration, a memory protection unit, and operation up to 168 MHz. The 512 KB Flash configuration provides room for application code and constants. Listed connectivity includes CANbus, I2C, SPI, I2S, UART/USART, USB OTG, IrDA, LINbus, and EBI/EMI, while listed peripherals include DMA, PWM, LCD support, watchdog, brown-out detection, and power-on reset.
The target order code identifies a 90-WLCSP package and an active device. Its high-performance core is appropriate for real-time motor and industrial control, while the broad interface set supports sensors, communications, data acquisition, and external memories. The exact pinout, electrical limits, clock configuration, and memory-map details should be confirmed from the STMicroelectronics STM32F405 family documentation before layout or firmware deployment.
Typical application roles include industrial controllers, connected metering equipment, motor-control boards, embedded automation modules, and IoT edge devices. Designers should plan decoupling and exposed-ball connectivity carefully in the WLCSP footprint, and should use STM32Cube or the supported toolchain to configure clocks, pins, memory, and peripherals.
The most important sourcing consideration is package-specific validation. The available verified data identifies 90-WLCSP, but it does not provide a complete verified list of pin-compatible alternatives or pricing tiers. This page therefore distinguishes confirmed data from missing engineering fields rather than inventing replacement parts or commercial values.
This product record synthesizes the verified STMicroelectronics family information, distributor references, application guidance, and design cautions. It is intended to support engineering selection and procurement review while directing engineers to the manufacturer datasheet for final electrical, pinout, and qualification decisions.

典型應用
STM32F405OEY6BTR 適用於 6 應用s: Industrial Automation Controller, IoT Edge Device, Motor Control System, Connected Metering Equipment, Data Acquisition and Signal Processing, Embedded Communication Gateway.
Industrial Automation Controller
STM32F405OEY6BTR fits industrial automation control because its Arm Cortex-M4 core operates up to 168 MHz and includes DSP instructions and an FPU for responsive control logic. The verified connectivity list includes CANbus, UART/USART, SPI, and I2C, allowing the controller to connect to sensors, actuators, operator interfaces, and service equipment. DMA and PWM resources can reduce processor involvement in data movement and timing-sensitive outputs. Use the device only after confirming the required voltage range, temperature range, isolation, EMC, and watchdog architecture against the family datasheet.
推薦
IoT Edge Device
The STM32F405OEY6BTR is appropriate for an IoT edge controller when local processing must occur close to sensors or actuators. Its 168 MHz Cortex-M4 performance, 512 KB Flash configuration, USB OTG, UART/USART, SPI, and I2C interfaces support connected sensing, protocol handling, and local control. The verified source specifically associates this family with IoT devices and low-power board designs. Before deployment, compare standby and active current, wireless-module power requirements, antenna integration, security configuration, and the exact 90-WLCSP footprint against the product design.
推薦
Motor Control System
STM32F405OEY6BTR can serve as the supervisory or real-time control MCU in a motor-control board. The Cortex-M4 core with DSP instructions and an FPU supports numerical control algorithms, while PWM and DMA resources help coordinate timing-critical operations. CANbus, UART/USART, and other serial interfaces can connect motor drives to supervisory controls or diagnostics. The verified application listing explicitly includes motor control. Confirm timer assignments, PWM resolution, analog front-end requirements, current limits, thermal performance, and fault-safe shutdown behavior in the manufacturer documentation before layout release.
推薦
Connected Metering Equipment
STM32F405OEY6BTR is well matched to metering equipment that must acquire, process, and communicate local measurements. Its listed EBI/EMI, SPI, I2C, UART/USART, and CANbus resources can connect analog front ends, memory, sensors, and remote communications. The 512 KB Flash capacity provides a defined code-storage starting point, while DMA and the 168 MHz core can support time-critical acquisition and filtering. Validate the required measurement accuracy, ADC and timer resources, calibration strategy, communication protocol, and power budget against the verified family documentation.
推薦
Data Acquisition and Signal Processing
STM32F405OEY6BTR can support compact signal-processing and data-acquisition nodes because its Cortex-M4 core reaches 168 MHz and provides DSP instructions plus an FPU. Listed DMA, SPI, I2S, UART/USART, and USB OTG interfaces create useful paths for sensors, converters, storage, and host connectivity. The adaptive real-time accelerator is also identified as a family feature and may help Flash-based execution in suitable designs. Confirm interrupt latency, DMA channel assignments, ADC characteristics, input bandwidth, memory availability, and deterministic timing before claiming application performance.
推薦
Embedded Communication Gateway
STM32F405OEY6BTR can form the central MCU of an embedded communication gateway when multiple serial interfaces and moderate local processing are needed. The verified feature list includes CANbus, USB OTG, UART/USART, SPI, I2C, IrDA, LINbus, and EBI/EMI, while DMA can offload transfers from the 168 MHz core. This combination suits protocol conversion, local routing, and supervisory control. Engineering review should confirm buffer strategy, interrupt priorities, electrical transients, connector protection, firmware update method, and the exact pin multiplexing required by the 90-WLCSP package.

主要差異化特點
- High-performance Cortex-M4 integration (對比STM32L151VBH6)
- Broad verified connectivity set (對比STM32F413VGH6)
- Defined Flash and package identity (對比STM32F405VGT6TR)
設計說明
The verified package is 90-WLCSP, so the PCB layout should be treated as a fine-pitch assembly task rather than a conventional leaded or large-outline design. Confirm the official package drawing, ball map, land pattern, solder-mask definition, paste stencil, and assembly process before release. Keep decoupling and any exposed thermal or ground-ball connections aligned with the manufacturer recommendations; the supplied data does not include the complete pin mapping or recommended capacitor values.
Validate the complete power tree and signal-level limits from the STM32F405 family documentation before connecting external buses or sensors. The supplied data confirms a 168 MHz Cortex-M4 device with USB OTG, CANbus, and multiple serial interfaces, but it does not specify supply voltage, current limits, pin tolerances, or power sequencing. Use local decoupling and transient protection appropriate to the actual design, and verify every external interface against the electrical limits rather than relying on generic MCU assumptions.
Do not treat a related STM32 MPN as a drop-in replacement without checking the package, pin assignment, memory, peripheral multiplexing, and electrical limits. The supplied evidence identifies STM32F405OEY6BTR as 90-WLCSP with 512 KB Flash, while the cross-reference results did not establish a verified compatible replacement. Firmware startup, clock settings, peripheral instances, and pin multiplexing also require device-specific validation; a successful package fit alone is not sufficient.
合規資訊
The supplied verified data identifies an active STMicroelectronics microcontroller and an industrial, IoT, automation, motor-control, metering, and low-power application context. It does not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification claims.
