STM32F405VGT7 - 168MHz Cortex-M4 1MB MCU | STMicroelectronics
MPN: STM32F405VGT7 ✗ Cuối đờiSTM32F405VGT7 Tóm tắt
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 embedded-processing hierarchy: ARM Cortex-M4 core, 32-bit microcontroller, embedded controller, and semiconductor. This classification places the device between simple fixed-function controllers and higher-level application processors, making it suitable for real-time control, communications, data acquisition, and signal-processing systems.
The STM32F405VGT7 combines a 1 M x 8 Flash configuration with a maximum clock frequency of 168 MHz. The Cortex-M4 core includes floating-point and DSP capabilities according to the verified STM32F405 family data. The device is associated with USB OTG high-speed and full-speed, Ethernet, 17 timers, three ADCs, 15 communication interfaces, and camera support, as stated in the verified datasheet summary. These peripherals enable consolidated control functions without requiring several discrete interface devices.
Its 100-LQFP package provides a large pin count compared with smaller MCU packages, supporting broad access to GPIO and mixed-signal resources. The verified data specifies a 14 x 14 mm package, but individual pin names, electrical limits, memory sizes beyond the stated Flash value, and absolute maximum ratings were not provided and therefore require manufacturer-document confirmation before PCB release.
Typical applications include industrial automation, communications equipment, USB and Ethernet-connected embedded systems, motor and motion control, instrumentation, and camera-enabled embedded products. The 168 MHz Cortex-M4 core is useful for control loops and signal-processing workloads, while the listed USB, Ethernet, timer, and ADC resources support connected measurement and automation designs.
Design should preserve the STM32F4 power, clock, decoupling, and decoupling-pin requirements from the manufacturer datasheet. Firmware migration to another STM32F4 device must verify package pin assignment, clock tree, peripheral availability, memory map, startup code, and board-level connectivity. This page synthesizes verified distributor data and explicitly marks specifications that were not available instead of estimating them.

Ứng dụng tiêu biểu
STM32F405VGT7 phù hợp cho 6 Áp dụngs: Industrial Automation Controller, USB Connected Embedded Control, Ethernet Networked Embedded System, Precision Data Acquisition, Motion and Timing Control, Camera-Enabled Embedded Product.
Industrial Automation Controller
The STM32F405VGT7 fits industrial automation controllers that need deterministic real-time control alongside communications and data acquisition. Its verified 168 MHz ARM Cortex-M4 core, three ADC resources, and 17 timers support sensor sampling, timing, and actuator sequencing in a single controller. USB OTG HS/FS and Ethernet connectivity can provide service, logging, or supervisory links when the board includes the required transceivers and connectors. Compared with a lower-frequency control MCU, the 168 MHz core provides more compute headroom for control algorithms, diagnostics, and protocol processing. The 100-LQFP package exposes more I/O than a small-outline package, which helps when multiple digital and analog resources are required. Firmware and electrical validation remain necessary before production release.
Được đề xuất
USB Connected Embedded Control
The STM32F405VGT7 is suitable for USB-connected embedded control products because the verified family data lists USB OTG high-speed and full-speed functionality alongside a 168 MHz Cortex-M4 core. USB can be used for configuration, diagnostics, firmware update, or a control interface, while timers and ADCs support local sensing and machine control. The 3.3 V supply requirement and 100-LQFP footprint make the device compatible with multilayer embedded-control designs, but the USB connector, protection components, clock source, and transceiver path must be designed from authoritative electrical data. USB bus layout should control impedance and minimize noise near analog sections. Firmware drivers and device configuration must also be verified for the exact STMicroelectronics part revision.
Được đề xuất
Ethernet Networked Embedded System
The STM32F405VGT7 supports embedded systems that need network connectivity alongside substantial control processing. The verified STM32F405 family summary lists Ethernet, USB OTG, multiple timers, three ADCs, and 15 communication interfaces, allowing one MCU to coordinate network communication, measurement, and machine functions. The Cortex-M4 FPU and DSP capability can support signal-processing or control tasks when the firmware is compiled for those instructions. Ethernet implementation still requires an appropriate PHY or MAC-level board design, magnetic isolation or coupling components, termination, and controlled-impedance traces. The 100-LQFP package gives access to a broad pin set, but exact Ethernet pin assignment and electrical limits must be taken from the manufacturer documentation. Firmware porting and timing validation are essential if the design is reused from another MCU.
Được đề xuất
Precision Data Acquisition
The STM32F405VGT7 is appropriate for precision data-acquisition systems that combine analog measurement with embedded signal processing. The verified family data identifies three ADCs and an ARM Cortex-M4 processor with FPU and DSP capability, supporting sensor conditioning, digital filtering, calibration, and data packaging. At up to 168 MHz, the core can process multiple acquisition and control tasks while handling communications through the listed USB or Ethernet resources. The 3.3 V operating supply and 100-LQFP package support integration into compact instrumentation, but ADC resolution, sampling rate, reference accuracy, input impedance, and acquisition timing were not supplied and must be verified in the manufacturer datasheet. Analog and digital layout should be separated carefully, with grounding and filtering selected for the measured signal bandwidth.
Được đề xuất
Motion and Timing Control
The STM32F405VGT7 can serve as a motion-control or precision timing controller because the verified data lists 17 timers and a maximum CPU frequency of 168 MHz. Timers can generate capture, compare, PWM, or periodic-control events, while the Cortex-M4 core handles state machines, interpolation, diagnostics, and communication. This combination is useful for industrial motion equipment, test systems, and embedded instrumentation where deterministic timing and real-time computation are important. The 100-LQFP package provides a comparatively high pin count, which can help distribute timer and control signals. Actual timer clock sources, resolution, trigger paths, and output electrical characteristics are not included in the supplied data and must be checked in the official documentation. Firmware timing tests are recommended because peripheral clocks and interrupt latency affect end-to-end control performance.
Được đề xuất
Camera-Enabled Embedded Product
The STM32F405VGT7 is suited to camera-enabled embedded products because the verified STM32F405 family summary lists camera support together with USB OTG HS/FS, Ethernet, DSP capability, and a 168 MHz Cortex-M4 core. These resources can support image acquisition, preprocessing, control, logging, and network or USB transfer when the selected camera interface and supporting circuitry are matched to the MCU. The Cortex-M4 FPU and DSP support can reduce the computational burden of basic filtering and image operations, although actual throughput depends on image size, memory bandwidth, compiler, and algorithm. The 100-LQFP package offers many external signals but does not remove the need for careful connector, clock, power, and signal-integrity design. Pin mappings, DMA behavior, and camera timing must be validated against the official device documentation before layout release.

Ghi chú thiết kế
Use the official STMicroelectronics reference schematic and datasheet to define the STM32F405VGT7 supply rails, decoupling network, reset circuit, and boot configuration. The verified data identifies a 3.3 V supply for this part, but it does not provide regulator current limits, analog-supply tolerances, or pin-level absolute maximum ratings. Do not infer those values from the family description. Place required bypass capacitors close to their associated supply pins, keep high-current digital paths away from sensitive analog routing, and verify startup and brownout behavior on the final board.
The 100-LQFP 14 x 14 mm package requires a footprint with correct lead pitch, span, exposed thermal or pad requirements, and assembly clearances. Because the supplied data does not include the complete pin names or dimensions, use the current manufacturer package drawing rather than a generic LQFP footprint. Confirm pin-1 orientation against the PCB silkscreen and assembly drawing. For USB, Ethernet, and high-speed signals, use the manufacturer reference stack-up and routing guidance to control impedance and minimize discontinuities.
Treat USB and Ethernet routes as constrained high-speed interfaces even though the verified data only identifies the available connectivity categories. Match trace impedance to the selected transceiver or PHY, provide continuous reference planes where practical, avoid splits and unnecessary stubs, and place termination and protection components according to the reference design. Separate clocks, high-current switching nodes, and analog inputs where possible. Validate eye diagrams, timing, and radiated or conducted emissions on the assembled PCB rather than relying only on schematic review.
Do not treat STM32F407VGT6TR, STM32F405ZGT7TR, or GD32F407 as automatically interchangeable with STM32F405VGT7. The supplied cross-reference material describes some parts as functional alternatives, and one candidate uses a 144-LQFP package rather than the target 100-LQFP package. Before substitution, verify pin-by-pin connectivity, Flash and SRAM, clock limits, voltage and temperature ratings, peripheral mapping, DMA behavior, startup code, and production test requirements. A functional alternative may require firmware porting and full board re-validation.
