STM32F103RFT6 概要
An STM32F1 microcontroller is a 32-bit embedded-control component combining a processor core, program Flash, static RAM, GPIO, timers, analog converters, and communication interfaces. STM32F1 devices belong to the microcontroller hierarchy, where they sit between a general-purpose microprocessor and simpler fixed-function embedded controllers. The Cortex-M3 core uses a reduced-instruction architecture optimized for control workloads, interrupt handling, and real-time embedded applications.
The supplied specifications identify the STM32F103RFT6 with 768 KB program Flash, 96 KB RAM, 51 I/O pins, a 72 MHz operating frequency, and a 64-LQFP package. The device also belongs to the STM32F103 XL-density family and is associated with USB, CAN, timers, ADCs, and communication interfaces. These features support designs requiring multiple serial peripherals, control-loop timing, data acquisition, and external connectivity rather than a simple GPIO-only control node.
The STM32F103RFT6 is suitable for industrial automation, motor control, communications, USB-enabled embedded products, CAN-connected equipment, and general-purpose control boards. Its 51 available I/O pins provide connectivity for sensors, actuators, displays, memory, transceivers, and status indicators. The 768 KB Flash capacity offers room for a larger application, bootloader, protocol stack, or logging subsystem than lower-density STM32F1 variants, while 96 KB RAM supports buffered communications and control data.
The 64-LQFP package is mechanically suited to leaded PCB assembly and provides a documented alternative to smaller fine-pitch packages when inspection, rework, or hand assembly matters. Designers should confirm the exact pinout, electrical limits, clock configuration, startup behavior, and peripheral assignments from the manufacturer datasheet before finalizing a board. STM32F103RFT6 is supplied in tray packaging according to the verified distributor data.
This product page combines distributor specifications, manufacturer-related sourcing information, and engineering-oriented application guidance. It also records the verified availability of same-footprint alternatives without treating a pin-compatible candidate as automatically equivalent in firmware, timing, or analog behavior. The STM32F103RFT6 is therefore best understood as a high-memory STM32F1 MCU platform selected when its documented resources and package match the system requirements.

主な用途
STM32F103RFT6 の用途: 7 件s: Industrial Automation Controller, USB-Enabled Embedded Product, CAN-Connected Equipment, Motor Control and Embedded Automation, Data Acquisition and Sensor Hub, Communications Gateway, General Embedded Control Board.
Industrial Automation Controller
The STM32F103RFT6 is a strong fit for an industrial automation controller because its 72 MHz ARM Cortex-M3 core can execute control logic and communication tasks while 51 I/O pins provide ample connections for sensors, actuators, status LEDs, and external interfaces. The 768 KB Flash and 96 KB RAM leave room for application code, diagnostics, data buffers, and protocol state. USB and CAN support can simplify connection to a host computer, service tool, or networked industrial node. A typical design would assign timers to deterministic control functions, use the ADCs for analog process inputs, and use serial interfaces for fieldbus or local operator-panel communication.
おすすめ
USB-Enabled Embedded Product
For USB-enabled embedded products, the STM32F103RFT6 combines a 72 MHz 32-bit Cortex-M3 core, 768 KB Flash, and USB capability in a 64-LQFP package. Firmware can manage USB enumeration, control transfers, data buffering, and application-specific tasks without requiring a separate USB interface controller. The larger memory footprint is useful for protocol stacks, configuration storage, boot logic, and diagnostic features. A practical implementation should verify the exact USB pin assignment, transceiver requirements, clock configuration, and power states against the manufacturer documentation before finalizing the PCB.
おすすめ
CAN-Connected Equipment
The STM32F103RFT6 is suitable for CAN-connected equipment because the verified technical listing identifies CAN communication support alongside the Cortex-M3 core and substantial internal memory. A controller can handle message filtering, periodic transmission, diagnostics, and local actuator logic while using CAN for distributed control. The 51 I/O pins can support isolated transceivers, digital inputs, outputs, and status indicators. For industrial or vehicle-like environments, review transceiver selection, termination, isolation, fault behavior, and supply requirements separately from the MCU itself; those external details are not fully specified in the supplied data.
おすすめ
Motor Control and Embedded Automation
The STM32F103RFT6 can serve as the control hub in a compact motor-control or embedded-automation design because the 72 MHz Cortex-M3 core provides computational headroom and the device includes timers and multiple ADCs. Timers can generate precise control periods or capture input events, while ADC channels can monitor current, position, temperature, or analog sensor signals. The 768 KB Flash and 96 KB RAM support a control loop, parameter storage, communications, and diagnostics. Exact PWM channels, pin multiplexing, timer clock limits, and analog input ranges must be checked against the device documentation for the selected board and motor-driver architecture.
おすすめ
Data Acquisition and Sensor Hub
The STM32F103RFT6 is appropriate for a sensor hub or data-acquisition node because it combines three ADCs, 51 I/O pins, 96 KB RAM, and 768 KB Flash in one 64-LQFP device. The MCU can sample analog channels, condition data in firmware, buffer results, and forward them through USB, CAN, or serial communications. Its memory supports local filtering, calibration tables, timestamp handling, and diagnostic data. Analog accuracy and sensor interface details depend on the external front end, reference, filtering, grounding, and supply design; those values are not supplied by the verified search results and should be validated separately.
おすすめ
Communications Gateway
A communications gateway can use the STM32F103RFT6 to bridge embedded protocols because the device combines a 32-bit Cortex-M3 core, USB, CAN, multiple communication interfaces, and 768 KB Flash. Firmware can maintain protocol state machines, frame routing, diagnostics, and configuration handling across local serial and networked links. The 96 KB RAM provides useful working space for buffering, while the 51 I/O pins support status, control, and transceiver interfaces. Designers should verify baud-rate support, peripheral mapping, electrical levels, and timing against the exact application before committing to a gateway architecture.
おすすめ
General Embedded Control Board
The STM32F103RFT6 works well as a general embedded-control platform for prototypes and production controllers requiring more resources than a basic microcontroller. Its 72 MHz ARM Cortex-M3 core, 768 KB Flash, 96 KB RAM, and 51 I/O pins support real-time firmware, peripheral control, human-interface inputs, logging, and communications. The 64-LQFP package in tray packaging is straightforward for leaded PCB assembly and can be advantageous when inspection or rework is important. A complete design still requires verified clocking, decoupling, programming access, reset behavior, and exact pin multiplexing from the manufacturer documentation.

設計ノート
The verified data identifies STM32F103RFT6 operation at 2.5 V or 3.3 V, but it does not provide the complete electrical limits or regulator requirements. Confirm the selected supply range, decoupling values, analog and digital ground strategy, and power-consumption budget in the manufacturer datasheet before layout. Place bulk and local bypass capacitors according to the device's recommended application circuit, and keep switching-regulator noise away from sensitive analog inputs.
Use the exact 64-LQFP land pattern and pin numbering from the manufacturer documentation. Keep programming access, reset, oscillator, and decoupling connections short and route them away from high-current switching paths. The verified package is 10 mm by 10 mm, but package size alone does not establish the land pattern, exposed-pad arrangement, or pin functions. Validate the footprint with the selected orderable part and assembly house before release.
Do not treat a same-footprint alternative as automatically firmware-compatible. The verified GD32F103 comparison reports a 108 MHz maximum clock versus 72 MHz for STM32F103RFT6, SRAM-buffered zero-wait Flash, and different ADC behavior. When evaluating a second source, test clock configuration, interrupt timing, startup, USB and CAN operation, Flash wait-state assumptions, and analog measurements on production-intent hardware.
For USB, CAN, or other communication interfaces, preserve the external transceiver and signal-integrity requirements defined by the selected interface. Confirm whether the application uses a crystal, internal oscillator, or external clock source and route the timing network according to the reference design. Avoid assuming that identical package dimensions guarantee identical pin multiplexing; verify every alternate-function connection in the device documentation.
No verified power-dissipation or thermal-resistance figures were supplied for the STM32F103RFT6. Estimated thermal calculations cannot be performed without the operating voltage, current, package thermal data, and board copper area. During design review, calculate worst-case internal and external dissipation using manufacturer limits, then verify junction temperature and soldering-process requirements with the actual PCB and enclosure.
