STM32F103RGT7 概要
The STM32F103 is a 32-bit microcontroller, or MCU, combining a RISC processor core with embedded Flash, SRAM, clocking, communications, timers, and GPIO resources. In the system hierarchy, an MCU is a semiconductor and embedded-control IC that executes firmware while directly controlling sensors, actuators, communications, and human-machine interfaces. The Cortex-M3 architecture provides a deterministic instruction environment suitable for real-time embedded control.
Key verified features include operation up to 72 MHz, 1 MB of Flash memory, up to 96 KB SRAM, three 12-bit ADCs, three timers, and support for three APB buses. The high Flash capacity allows larger firmware images, protocol stacks, bootloader code, and application logic to be consolidated on one device. The 64-LQFP package also exposes a broad peripheral complement while remaining compatible with conventional leaded-board assembly and inspection.
The STM32F103RGT7 combines a high-performance ARM Cortex-M3 core with memory and peripheral resources connected through two APB buses. Its XL-density designation is reflected in the 1 MB Flash configuration, making it more suitable than smaller-density devices for gateways, industrial controllers, data acquisition systems, and connected embedded products. The verified distributor description identifies the device as a 32-bit, 72 MHz Cortex-M3 MCU with 1M x 8 Flash.
Typical applications include industrial automation, motor control, communications equipment, data acquisition, instrumentation, and embedded gateways. Three ADC channels support analog measurement, while multiple timers support timing, waveform generation, motor-control, and encoder-related functions. The large Flash and SRAM resources also support protocol conversion and supervisory firmware without requiring a separate external memory device.
Designers should verify the exact peripheral pin mapping, clock configuration, operating voltage limits, and startup behavior against the manufacturer datasheet before layout release. Decoupling, oscillator stability, programming access, reset circuitry, and thermal performance remain PCB-level priorities. STM32F103RGT7 sourcing is supported by the ST product page, DigiKey, Mouser, LCSC, and ST eStore listings captured in the verified data.
This product page consolidates verified distributor specifications, package information, sourcing links, and design guidance into a compact engineering reference. It does not invent electrical limits or pin functions that were absent from the supplied source data.

主な用途
STM32F103RGT7 の用途: 6 件s: Industrial Automation Controller, Data Acquisition System, Motor Control and Automation, Communications Gateway, Embedded Test and Measurement, Smart Sensor Node.
Industrial Automation Controller
The STM32F103RGT7 fits industrial automation controllers that combine sequencing, communications, analog monitoring, and timing functions. Its 72 MHz Cortex-M3 core provides processing headroom, while 1 MB Flash supports control firmware, configuration data, and communication stacks. Three 12-bit ADCs can monitor sensors or process variables, and three timers support periodic tasks, pulse generation, or actuator timing. The 64-LQFP 10 x 10 mm package provides access to the family’s GPIO and peripheral resources while retaining a conventional surface-mount form factor. Design validation should confirm pin multiplexing, clocking, isolation requirements, and industrial temperature limits against the manufacturer documentation.
おすすめ
Data Acquisition System
The STM32F103RGT7 is appropriate for multi-channel data acquisition and instrumentation because it combines three 12-bit ADCs with a 72 MHz processing core and substantial memory. Firmware can sample analog inputs, apply filtering, maintain calibration data, and format results for a communications interface. The 1 MB Flash capacity is useful for application code, bootloader logic, and protocol support, while up to 96 KB SRAM provides working memory for acquisition buffers. Designers should verify analog input ranges, sampling characteristics, reference-voltage requirements, and the exact ADC pin locations in the datasheet before finalizing the analog front end.
おすすめ
Motor Control and Automation
The STM32F103RGT7 can serve as the control MCU for stepper, BLDC, or other timing-sensitive embedded motor systems. Its 72 MHz core supports deterministic control-loop execution, while three timers provide resources for PWM generation, input capture, and timing functions. Three ADCs support current, position, or feedback monitoring when the board provides suitable sensing circuitry. The 64-LQFP package exposes a broad pin set, but motor-control designs must carefully validate timer channel mapping, pin multiplexing, dead-time requirements, protection inputs, and power-stage isolation. The MCU does not replace external gate drivers, current sensing, or power MOSFETs.
おすすめ
Communications Gateway
The STM32F103RGT7 is suitable for protocol-conversion and embedded gateway products where local control and multiple serial interfaces are required. The 72 MHz Cortex-M3 core can manage protocol state machines, buffering, and supervisory logic, while 1 MB Flash accommodates firmware and protocol libraries. The family’s peripheral resources support communications-oriented embedded designs, although the exact USART, SPI, USB, and timer availability must be checked for the selected package and pinout. A gateway design should include deterministic boot behavior, watchdogs, brownout handling, and secure firmware update support. Use the manufacturer documentation to verify peripheral multiplexing before assigning connector signals.
おすすめ
Embedded Test and Measurement
The STM32F103RGT7 can be used in embedded measurement products that need local signal conditioning control, calibration, status reporting, and a host interface. Its three 12-bit ADCs support analog measurement channels, while the 72 MHz core can perform filtering, statistics, and instrument-control tasks. The 1 MB Flash and up to 96 KB SRAM provide room for firmware, calibration tables, and acquisition data. The 64-LQFP package is practical for boards requiring many external connections, but analog precision depends on reference, grounding, layout, and input-conditioning design. Verify the specified ADC accuracy, voltage limits, acquisition timing, and operating temperature in the official datasheet.
おすすめ
Smart Sensor Node
The STM32F103RGT7 fits smart sensor nodes that must acquire analog or digital measurements, apply local processing, and forward results over a communications link. The three ADCs support sensor interfaces, while the high-performance 72 MHz Cortex-M3 core can execute filtering, diagnostics, and protocol handling. With 1 MB Flash, the device can combine application firmware, bootloader, and communication code in one package. The broad LQFP lead arrangement simplifies access to GPIO and peripheral signals compared with a very small package. Before deployment, validate sensor input voltage ranges, low-power behavior, wake-up sources, clock accuracy, and environmental requirements; those details were not included in the supplied verified specification set.

設計ノート
Place the MCU power pins and decoupling network according to the manufacturer recommended layout. The supplied data confirms a 64-LQFP package but does not provide the complete pinout or pin-specific bypass requirements. Before release, use the official STM32F103RG documentation to map VDD and VSS pins, identify all required supply connections, and route high-current return paths without splitting ground planes unnecessarily.
Do not assume that an STM32F103-family alternative is interchangeable merely because it uses an LQFP package. Verify the exact pin count, exposed-pad requirements, power pins, oscillator pins, reset behavior, boot configuration, peripheral multiplexing, and package dimensions. The verified cross-reference material specifically identifies GD32F103 as a compatibility candidate, but firmware and timing behavior still require qualification.
For communication or high-speed control signals, route traces with controlled impedance where applicable and keep switching nodes away from ADC inputs and oscillator circuits. The 72 MHz core can create fast edge rates even when external buses are moderate speed. Use short return paths, maintain continuous reference planes, and validate timing, ringing, and EMI behavior with the final board stack-up and enclosure.
The verified specifications do not provide the STM32F103RGT7 supply-voltage limits or absolute maximum ratings, so power-supply design must be based on the manufacturer datasheet rather than assumptions. Confirm the permitted VDD range, regulator tolerance, startup sequencing, brownout behavior, and current budget. Include a controlled reset and programming interface so the MCU can be recovered without removing it from the assembled product.
コンプライアンス情報
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for STM32F103RGT7. Compliance should be confirmed from the exact STMicroelectronics product documentation or declaration.
