STM32F405RGT7 - 168MHz Cortex-M4 MCU | STMicroelectronics
MPN: STM32F405RGT7 ✓ فعالSTM32F405RGT7 نمای کلی
A microcontroller is a programmable semiconductor that combines a CPU core, memory, peripherals, and interfaces on one integrated circuit. The STM32F4 family belongs to the MCU hierarchy, with the Cortex-M4 core providing real-time control processing and the STM32F405RGT7 adding high-speed connectivity and analog peripherals for embedded systems.
Key features include an Arm Cortex-M4 processor operating up to 168 MHz, 1 MB Flash, and up to 192 KB SRAM plus 4 KB backup SRAM according to the verified family data. The device provides 210 DMIPS, 1.25 DMIPS/MHz, an Adaptive Real-Time Accelerator for zero-wait-state Flash execution, and a full DSP instruction set. Integrated connectivity includes USB OTG high-speed and full-speed, Ethernet, and multiple communication interfaces.
The STM32F405RGT7 is designed for high-performance embedded control rather than general-purpose computing. Its 168 MHz core provides deterministic processing for motor control, communications, data acquisition, and multimedia subsystems. The FPU accelerates floating-point workloads, while the DSP instructions support filtering and other signal-processing operations without requiring an external processor.
Typical applications include industrial automation, motor and motion control, audio and digital signal processing, USB-connected equipment, Ethernet gateways, and camera or image-processing systems. The LQFP-64 package is inspectable and compatible with conventional leaded PCB assembly methods.
A key design consideration is that firmware, clock configuration, peripheral initialization, and memory mapping must match the STM32F4 family. Because the verified data does not provide the complete package pinout or exact individual alternative specifications, those fields are explicitly marked as data needed rather than inferred.
This page combines the manufacturer family data, distributor specifications, pricing references, application guidance, and drop-in alternatives into an engineering-focused product record. The alternatives are limited to verified candidates and are not padded with unverified cross-brand equivalents.

کاربردهای معمول
STM32F405RGT7 مناسب است برای 7 کاربردs: Industrial Automation, Motor and Motion Control, USB Connected Embedded Equipment, Ethernet Gateway, Audio and Digital Signal Processing, Data Acquisition and Sensor Systems, Camera and Embedded Imaging.
Industrial Automation
The STM32F405RGT7 fits industrial automation because its 168 MHz Cortex-M4 core, DSP instructions, 17 timers, and three ADCs support deterministic control and signal acquisition in one device. It can coordinate sensors, actuator logic, communications, and supervisory tasks while the ART Accelerator supports efficient zero-wait-state execution from Flash. Use it when the design needs more processing headroom than a basic Cortex-M microcontroller, but validate timing, memory, and peripheral availability against the complete STM32F405 datasheet.
پیشنهادی
Motor and Motion Control
The STM32F405RGT7 is appropriate for motor-control workloads because its 168 MHz core, single-precision FPU, DSP instructions, 17 timers, and three ADCs provide computation and sampling resources for current and position loops. The device can generate timer-based control signals and process feedback while handling communication tasks. A complete design still requires power stages, gate drivers, sensing components, current protection, and a thermal design appropriate to the motor system.
پیشنهادی
USB Connected Embedded Equipment
The STM32F405RGT7 supports USB OTG high-speed and full-speed connectivity, making it suitable for USB-connected instrumentation, service tools, and embedded peripherals. Its 168 MHz Cortex-M4 core and 1 MB Flash provide room for protocol handling, control logic, and application firmware. Board design must account for the required USB transceiver, connector, impedance-controlled routing, power-supply requirements, and the device-specific USB electrical characteristics in the manufacturer datasheet.
پیشنهادی
Ethernet Gateway
The STM32F405RGT7 can serve as the control MCU in an Ethernet gateway because the verified family data identifies Ethernet connectivity alongside a 168 MHz Cortex-M4 core and substantial Flash memory. It can coordinate local control, protocol conversion, logging, and network management. The implementation requires an appropriate Ethernet PHY or MAC-related circuitry, magnetic components or cabling interface as applicable, isolation requirements, and careful clock and signal-integrity layout.
پیشنهادی
Audio and Digital Signal Processing
The STM32F405RGT7's Cortex-M4 core operates up to 168 MHz and includes a single-precision FPU plus DSP instructions, providing a strong basis for real-time audio filtering, modulation, or signal analysis. The 1 MB Flash and 192 KB SRAM can hold control code, buffers, and algorithms within the limits of the selected memory configuration. Designers should evaluate CPU margin, DMA behavior, audio-clock sourcing, and external codec interface requirements before finalizing the signal chain.
پیشنهادی
Data Acquisition and Sensor Systems
The STM32F405RGT7 suits sensor hubs and data-acquisition systems because three ADCs, 17 timers, and 15 communication interfaces can coordinate multiple sensing and timing functions. Its 168 MHz core provides more headroom for filtering, calibration, and communication than a basic MCU. Confirm ADC characteristics, trigger timing, DMA channels, input voltage limits, and sensor-interface requirements in the manufacturer datasheet before selecting external analog front-end components.
پیشنهادی
Camera and Embedded Imaging
The STM32F405RGT7 can be used as a supervisory controller in camera or embedded imaging systems because the verified family data mentions camera support and provides a high-performance Cortex-M4 core with DSP instructions. It can manage sensor configuration, buffers, timing, and communications while an external image sensor or dedicated accelerator handles pixel throughput. The exact camera interface, DMA requirements, memory bandwidth, and package-level pin assignments must be checked in the full datasheet.

یادداشت‌های طراحی
Design the STM32F405RGT7 power rails from the manufacturer electrical-characteristics section rather than from nominal MCU inputs alone. Place bulk capacitance near the supply pins, provide local decoupling for switching-sensitive analog and digital sections, and keep the 3.3 V rail within the exact operating limits stated in the datasheet. Sequence external transceivers and sensors carefully when their supply domains differ.
Route USB, Ethernet, and high-speed communication signals as controlled-impedance nets with continuous reference planes and minimized via transitions. Keep clocks away from analog inputs and sensitive communication traces. Follow the recommended external-component values, termination, and layout guidance in the manufacturer datasheet and validate signal integrity with the final enclosure, connectors, cables, and power-supply design.
Use a solid ground-plane structure and place decoupling capacitors close to the corresponding STM32F405RGT7 supply pins. The 64-LQFP package is inspectable, but its lead pitch still requires careful stencil and assembly planning. Check the land pattern, pin numbering, exposed thermal requirements if applicable, and solder mask against the official package drawing before releasing the PCB files.
Do not assume that a similarly named STM32F405 or STM32F407 ordering code is automatically interchangeable. Confirm the exact package, pinout, memory, temperature, qualification, and orderable suffix in the manufacturer datasheet. For GD32F407 or other cross-brand substitutions, budget for peripheral-library changes, clock-tree changes, firmware porting, and board-level validation.
