STM32F411RET6U Übersicht
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and interface circuitry into one semiconductor package. The STM32F411 belongs to the STM32F4 family and combines an embedded ARM Cortex-M4 core, floating-point hardware, serial interfaces, timers, and connectivity functions. It is designed for embedded control, data acquisition, communication, and compact consumer or industrial products.
Key verified features include a 32-bit Cortex-M4 processor, 100 MHz maximum operating frequency, 512 KB Flash, 128 KB RAM, and USB OTG FS. The provided search data also describes 125 DMIPS and identifies the package as 64-LQFP. The ARM Cortex-M4 core provides a compact instruction set and efficient real-time execution, while the hardware FPU accelerates suitable floating-point operations without requiring a separate coprocessor.
The STM32F411RET6U is positioned for designs that require moderate embedded processing performance, USB connectivity, and a conventional leaded package. Its 64-LQFP construction supports visual inspection and prototyping workflows more readily than many fine-pitch land-grid-array packages, while still providing a substantial pin count for external sensors, actuators, communications, and memory.
Typical applications include USB-connected control systems, compact sensor nodes, industrial instrumentation, consumer accessories, motor-control peripherals, and communication equipment. Designers should verify voltage levels, clock configuration, pin multiplexing, power sequencing, decoupling, and peripheral assignments against the manufacturer datasheet before production release.
For a new design, the STM32F411RET6U is appropriate when the system needs a 100 MHz Cortex-M4 class MCU, 512 KB Flash, 128 KB RAM, and USB OTG FS without requiring the larger memory or peripheral set of an STM32F405 or STM32F407. A pin-compatible replacement should be selected only after checking the exact package, pin multiplexing, clock tree, interrupt mapping, and peripheral population.
This product record combines verified distributor and manufacturer search results with application guidance, source links, and explicit data gaps. It is intended to help engineers identify the correct STM32F411RET6U package and assess whether its verified resources match the target system.

Typische Anwendungen
STM32F411RET6U ist geeignet für 6 Anwendungs: USB-Connected Control Device, Compact Industrial Sensor Node, USB Audio and Measurement Front End, Motor and Peripheral Control, Portable Consumer Accessory, Communication Gateway Module.
USB-Connected Control Device
STM32F411RET6U is well matched to a USB-connected controller that needs a 100 MHz ARM Cortex-M4 core, 512 KB Flash, and 128 KB RAM. USB OTG FS provides a defined connectivity path for configuration, logging, or a device-class interface. The 64-LQFP package leaves accessible leads for buttons, status indicators, sensors, and external interface logic. Confirm USB power, transceiver, impedance, firmware support, and device-class requirements in the STMicroelectronics documentation.
Empfohlen
Compact Industrial Sensor Node
The STM32F411RET6U can serve as the local control processor for a compact sensor node because its 100 MHz Cortex-M4 core and 128 KB RAM provide room for sampling, filtering, and communications firmware. The verified 512 KB Flash supports embedded application code and configuration tables. Its 64-LQFP package is convenient for prototype boards and through-hole visual inspection. Industrial use requires confirmation of operating temperature, ESD, isolation, and environmental compliance.
Empfohlen
USB Audio and Measurement Front End
The MCU's 100 MHz Cortex-M4 processor and USB OTG FS interface make STM32F411RET6U a candidate for a measurement or audio-control peripheral that exchanges data over USB. Its 128 KB RAM can buffer application data, while the 64-LQFP package simplifies connection to external converters, clocks, and control signals. The verified data does not state audio converters or DAC specifications, so engineers must add and validate those components separately.
Empfohlen
Motor and Peripheral Control
STM32F411RET6U is appropriate for a compact motor or peripheral controller where real-time firmware, timers, and multiple external connections are required. The 64-lead package provides more physical connection points than a 48-pin UFQFPN alternative, and the 100 MHz core supports responsive control tasks. Motor-drive design still requires verified timer mappings, logic-level checks, protection components, current sensing, and thermal analysis against the complete datasheet.
Empfohlen
Portable Consumer Accessory
The STM32F411RET6U can support a portable consumer accessory that needs USB connectivity and a moderate embedded application workload. Its 512 KB Flash and 128 KB RAM provide more application storage than typical entry-level MCUs, while the 100 MHz Cortex-M4 core handles user-interface logic and device management. The verified package is 64-LQFP, so battery-powered designs must also verify sleep modes, current consumption, and board-level power behavior in the manufacturer documentation.
Empfohlen
Communication Gateway Module
STM32F411RET6U is a viable gateway controller for a compact communication module that must translate between USB and an external serial interface. The Cortex-M4 core can manage protocol processing and buffering, while USB OTG FS supports a standardized host or device connection. The verified source does not specify individual UART, SPI, I2C, or CAN pin assignments, so the designer must confirm multiplexing and electrical levels directly from the STM32F411 documentation.

Wichtigste Unterscheidungsmerkmale
- Verified 100 MHz Cortex-M4 performance class (vs. STM32F405RGT6)
- Larger 64-LQFP package and verified memory configuration (vs. STM32F411CEU6)
- USB OTG FS connectivity (vs. STM32F411CCY6TR)
Designhinweise
Verify the complete STM32F411RET6U supply-voltage range and current limits from the manufacturer datasheet before selecting regulators or USB power paths. The verified data confirms a 100 MHz MCU, 512 KB Flash, and 128 KB RAM but does not provide operating-voltage values. Add the required local decoupling directly at the supply pins and validate startup behavior across the required load and temperature conditions.
The part is specified in a 64-LQFP package measuring 10 x 10 mm. Before routing the PCB, download the exact STMicroelectronics package drawing and land pattern, confirm pin numbering and exposed assembly requirements, and maintain appropriate solder-mask and copper clearances. The supplied search data does not provide a complete pinout, so do not infer alternate-function assignments from the package name.
Plan USB and high-speed communication traces with controlled impedance, short return paths, and a continuous reference plane. Although USB OTG FS is listed as a device feature, the supplied data does not specify transceiver topology or exact electrical limits. Confirm the USB PHY requirements, connector protection, cable routing, and firmware support in the official STM32F411 documentation before PCB sign-off.
Do not treat an STM32 family member in a different package as a drop-in substitute. The supplied search results explicitly describe STM32F411CEU6 as UFQFPN-48 and STM32F411CCY6TR as WLCSP, while the target is 64-LQFP. Even a same-family device can differ in I/O count, alternate functions, memory, and firmware device configuration; validate the exact orderable MPN before substitution.
Compliance-Informationen
The supplied verified web data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed using current STMicroelectronics documentation.
