STM32F411VET6U 概要
A microcontroller integrates a processor core, memory, programmable peripherals, and interface controllers into one semiconductor. The STM32F411 belongs to the STM32F4 microcontroller family and the broader ARM Cortex-M embedded ecosystem. Its Cortex-M4 architecture provides deterministic control performance and single-precision floating-point capability for protocols, signal processing, industrial controls, and connected products.
The STM32F411VET6U combines 512 K x 8 Flash storage with 128 KB of SRAM and a stated performance of 125 DMIPS. Verified family data also identifies USB OTG full-speed support. These resources suit applications that need moderate local storage, real-time peripheral handling, and USB connectivity without an external host controller. The exact list of peripheral functions, clock limits, and electrical characteristics should be confirmed in the manufacturer documentation for the ordered ordering code.
Its 100-pin LQFP package provides a larger pin count than compact 48-pin devices, supporting a broader connection to external sensors, memories, converters, displays, and communication transceivers. The package increases routing flexibility but requires careful fanout, ground distribution, and decoupling. Because STM32F411 variants can differ by temperature range and order code, firmware and hardware validation must use the exact STM32F411VET6U documentation rather than assuming that every STM32F411 suffix is interchangeable.
Typical uses include USB-connected data acquisition, industrial control modules, medical instrumentation, audio and communications equipment, and compact embedded gateways. The ARM Cortex-M4 core, 128 KB SRAM, and USB capability are especially useful when a product must combine control-loop responsiveness with moderate protocol and data-processing workloads.
Designers should preserve the manufacturer's recommended power, decoupling, clock, and reset arrangements. USB differential routing requires controlled impedance and uninterrupted reference-plane continuity, while high-speed or sensitive analog signals need separate return paths. Firmware should also account for boot configuration, peripheral pin multiplexing, and the exact package pinout before PCB release.

主な用途
STM32F411VET6U の用途: 6 件s: USB Data-Acquisition Module, Industrial Control Controller, Medical Monitoring Instrument, USB Audio Interface, Communications Gateway, Embedded Sensor Node.
USB Data-Acquisition Module
The STM32F411VET6U fits USB data-acquisition modules because its ARM Cortex-M4 core runs at up to 100 MHz, while 512 KB Flash and 128 KB SRAM support firmware, sampling control, and local buffering. USB OTG full-speed provides a direct connectivity path to a host computer, reducing the need for a separate USB controller. The design should provide controlled-impedance USB routing, local decoupling, protected input conditioning, and firmware support for the selected sensor and sampling front end.
おすすめ
Industrial Control Controller
The STM32F411VET6U is suitable for compact industrial control modules that require deterministic embedded processing without a larger system-on-chip. Its 125 DMIPS Cortex-M4 performance supports control loops, state-machine management, and communication handling, while the 1.7 V to 3.6 V supply range fits low-voltage embedded rails. The 100-pin LQFP also provides more peripheral routing options than a small package, but the enclosure, EMC strategy, temperature grade, and long-term qualification must be validated separately.
おすすめ
Medical Monitoring Instrument
STM32F411VET6U can serve as the central controller in a medical monitoring instrument when its documented supply range, package, and exact ordering-code temperature grade fit the product requirements. The Cortex-M4 FPU supports signal-conditioning calculations, 128 KB RAM accommodates working buffers, and USB OTG full-speed supports data exchange with a host. Actual medical use requires separate electrical-safety, isolation, firmware-risk, and regulatory work; this MPN must not be treated as automatically medical-qualified.
おすすめ
USB Audio Interface
The STM32F411VET6U is a reasonable candidate for a USB audio interface because USB OTG full-speed connects the device to a host while the Cortex-M4 FPU handles real-time audio-related computation. The 512 KB Flash supports firmware and control tables, and 128 KB SRAM can support buffer and state management. Actual audio-clock behavior, codec interface, latency, and supported sample rates must be checked in the exact STM32F411 datasheet; the verified data alone does not establish a complete USB audio codec feature set.
おすすめ
Communications Gateway
STM32F411VET6U can be used in a small communications gateway that needs local protocol handling and a USB host interface. Its 100 MHz Cortex-M4 core provides headroom for framing, buffering, and supervisory tasks, while 512 KB Flash and 128 KB RAM support a more capable embedded image than a minimal microcontroller. The board should isolate high-current or noisy communication circuitry, provide robust power filtering, and validate signal levels, ESD protection, and timing for the selected external transceiver.
おすすめ
Embedded Sensor Node
The STM32F411VET6U can support an embedded sensor node that samples external sensors, performs local filtering, and reports data through USB or another serial interface. Its 128 KB SRAM provides working memory for buffers and control state, while the Cortex-M4 FPU accelerates suitable arithmetic without requiring a separate processor. Low-power behavior, sleep modes, battery regulation, sensor accuracy, and analog front-end limits are not specified in the supplied data and must be confirmed before battery-powered deployment.

設計ノート
Design the STM32F411VET6U supply around the verified 1.7 V to 3.6 V family range and the exact ordering-code electrical limits. Place local bypass capacitors at the device supply pins, keep the return path short, and separate analog or sensor supplies from switching and digital power where practical. Do not infer current consumption, startup behavior, or regulator selection from the family-level figures; confirm those values in the manufacturer datasheet before choosing the power tree.
Treat the USB interface as a controlled-impedance differential route. Keep the D+ and D+ pair together, maintain a continuous reference plane, minimize vias and stubs, and keep external switching nodes away from the pair. Also preserve short clock and reset paths, provide clean ground returns, and route unused pins according to the exact package pin table. The generic family pinout should not be copied without checking the STM32F411VET6U package documentation.
Do not assume that every STM32F411VET6 ordering suffix has identical commercial or temperature attributes. Verify the exact STM32F411VET6U datasheet, boot configuration, alternate-function mapping, and temperature grade. When migrating from STM32F411VET6 or STM32F411VET6TR, confirm that the package, pin functions, supply limits, USB support, and peripheral assignments are actually compatible before calling the change drop-in.
コンプライアンス情報
