STM32F103R6T6A - 72MHz 32-bit MCU | STMicroelectronics
N.º da peça: STM32F103R6T6A ✓ AtivoSTM32F103R6T6A Visão geral
A microcontroller is a semiconductor device that integrates a processor core, Flash program memory, RAM, clocks, interrupt controllers, and peripherals on one integrated circuit. The STM32F103R6T6A belongs to the STM32F1 performance-line family, combining an ARM Cortex-M3 RISC core with the broader microcontroller hierarchy of embedded processor, semiconductor, and electronic control system. Its 32-bit architecture supports efficient handling of control algorithms, communication protocols, and digital logic.
The principal verified features include a 72 MHz Cortex-M3 core, 32-bit processing, 32 KB of Flash, 64-pin LQFP packaging, and operation from 2.5 V or 3.3 V. The manufacturer describes the STM32F103x4 and STM32F103x6 devices as a performance-line family for 32-bit RISC processing. USB, CAN, and timer capabilities are associated with this family in the available family documentation, although complete peripheral details and electrical limits are not included in the supplied excerpts.
The 64-pin LQFP package exposes substantially more I/O than smaller 48-pin STM32F103 variants, making the device useful where an application requires multiple serial interfaces, timers, analog inputs, or digital control signals. Its 72 MHz clock rate provides more instruction throughput than lower-frequency Cortex-M3 devices while retaining compatibility with the established STM32 embedded ecosystem. Exact RAM capacity, flash organization, timer channels, and peripheral ratings require confirmation from the manufacturer datasheet.
Typical applications include industrial control modules, USB-connected data loggers, CAN-based equipment, motor and actuator controllers, communication interfaces, and compact consumer appliances. A design should use the manufacturer's pin, electrical-characteristic, clock, and application guidance to confirm every peripheral and signal.
PCB design should provide a stable 3.3 V supply, decoupling close to the power pins, an appropriate oscillator network, and clean grounding for communication interfaces. The exposed 64-pin footprint also requires careful fan-out and signal-integrity review when used with fast external buses or long board routes.
This page consolidates the verified distributor and manufacturer information, package-level alternatives, procurement details, and application-oriented design guidance. It also distinguishes explicitly verified specifications from parameters that still require confirmation from the official STM32F103R6T6A technical documentation.

Aplicações típicas
STM32F103R6T6A é adequado para 6 aplicaçãos: Industrial Control Modules, USB Communication Devices, CAN-Based Equipment, USB-to-CAN Gateway, Motor and Actuator Controllers, Data Logging and Sensor Hubs.
Industrial Control Modules
The STM32F103R6T6A fits compact industrial control modules that combine real-time logic acquisition with actuator or human-interface signals. Its 72 MHz ARM Cortex-M3 core provides higher instruction throughput than slower general-purpose microcontrollers, while the 64-pin LQFP exposes substantially more I/O than smaller STM32F103 packages. The verified 32 KB Flash must cover the control firmware, bootloader, and parameter data. Designers should map required timers, ADC channels, and communication pins against the official package drawing, then isolate switching-node energy from sensitive analog and communication paths.
Recomendado
USB Communication Devices
The STM32F103R6T6A can serve as the control device in USB-connected peripherals, adapters, and service tools because it combines a 72 MHz Cortex-M3 core with a generous 64-pin package. The available family description associates STM32F103 performance-line devices with USB and CAN capabilities, although the exact USB electrical and protocol requirements of this ordering code must be checked in the manufacturer datasheet. Firmware development should use the appropriate STM32 USB stack and account for the target's verified 32 KB Flash limit when sizing descriptors, boot code, and application functions.
Recomendado
CAN-Based Equipment
The STM32F103R6T6A is applicable to CAN-connected sensors, building controls, and industrial accessories because the STM32F103 family is identified with CAN functionality and provides 64 pins for supporting interfaces. A board using this MCU should reserve the required CAN transceiver, termination, common-mode protection, and connector resources while keeping the 72 MHz MCU and 32 KB Flash operating region within its design budget. The exact CAN bit timing, peripheral resources, and transceiver interface must be verified against the official STM32F103R6 documentation before release.
Recomendado
USB-to-CAN Gateway
The STM32F103R6T6A is well suited to a compact USB-to-CAN gateway because its 72 MHz Cortex-M3 core can coordinate protocol conversion between a USB host and an industrial CAN bus. The 64-pin LQFP allows USB, CAN, status indicators, configuration interfaces, and protection logic to coexist without an extremely dense footprint. Firmware size must be evaluated against the verified 32 KB Flash, and the final design must confirm USB and CAN electrical requirements from the manufacturer datasheet. Isolation, surge protection, and bus termination are separate system-level design decisions.
Recomendado
Motor and Actuator Controllers
The STM32F103R6T6A can implement compact motor, solenoid, and actuator controllers where real-time control must be combined with multiple digital I/O functions. Its 72 MHz 32-bit core provides computational margin for closed-loop control and communication, while 64 pins allow the controller to combine timer outputs, feedback inputs, status LEDs, and serial diagnostics. The exact timer channels, PWM frequency, encoder interfaces, and ADC performance must be confirmed before assigning pins. Power-stage layout requires separate high-current paths, local bulk decoupling, and careful control-signal isolation.
Recomendado
Data Logging and Sensor Hubs
The STM32F103R6T6A can support compact sensor hubs and data loggers that sample inputs, format records, and forward results through a serial or network interface. The 72 MHz Cortex-M3 core is suitable for protocol handling, and the 64-pin package leaves room for multiple sensors and expansion interfaces. The verified 32 KB Flash is the principal constraint and should be budgeted before adding protocols or buffered storage. Because the supplied excerpts do not confirm RAM, ADC channels, or sensor interfaces, designers must select them from the official datasheet and account for acquisition accuracy and conversion timing.

Notas de projeto
Power the STM32F103R6T6A from a stable 2.5 V or 3.3 V rail as specified by the manufacturer. Place the required bypass capacitors directly beside their associated power pins and provide adequate local bulk capacitance for switching loads on the same board. Separate analog, digital, and high-current return paths where possible so that motor, relay, or transceiver current does not produce ground movement across the MCU.
Verify the 64-pin LQFP land pattern against the current STMicroelectronics package drawing before releasing the PCB. Check pin-1 orientation, exposed pad requirements if applicable, pad dimensions, solder-mask clearance, and courtyard spacing rather than relying solely on the 10 x 10 mm body size. Because the supplied data does not include the official pin table, compare every PCB-library pin name and alternate function with the manufacturer package drawing.
Keep oscillator traces short, symmetrical, and separated from high-current switching paths. Route CAN, USB, and other communications away from inductors, relays, and motor-drive nodes, and use a continuous ground plane unless the complete system architecture requires a deliberate split. For mixed-signal measurements, partition the ADC inputs from digital switching activity and follow the manufacturer's application recommendations for grounding and filtering.
Do not treat a shared ARM Cortex-M3 core or a 64-pin footprint as proof of drop-in compatibility. The STM32F103R8T6A, STM32F103RC6A, and STM32F103RE6A candidates differ in memory organization, while GD32F103R6T6 introduces a different library environment and a reported 108 MHz clock ceiling. Validate Boot configuration, interrupt mappings, peripheral pin assignments, timing, and firmware before production substitution.
Informações de conformidade
The supplied verified snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not applicable because the available product information does not identify this ordering code as an automotive-qualified variant.
