STM32F103VBH6 概要
A microcontroller is an integrated circuit that executes firmware, reads inputs, controls outputs, and manages embedded-system resources. The STM32F103VBH6 belongs to the MCU hierarchy: ARM Cortex-M3 microcontroller, 32-bit embedded processor, and programmable control device. Its combination of 72 MHz processing, 128 KB Flash, and USB and CAN support makes it suitable for industrial controls, communication equipment, data acquisition, and motor-control prototypes where several peripherals are required on one device.
The verified device description identifies the part as a performance-line, ARM-based 32-bit MCU with Flash, USB, CAN, seven 16-bit timers, and two 12-bit, 1 microsecond ADC channels. The reported operating supply range is 2 V to 3.6 V, while one verified source also identifies RoHS compliance and an active lifecycle status. These features support low-voltage embedded designs that need high processing speed and integrated serial communications without requiring a separate external interface controller.
The Cortex-M3 core and 72 MHz operating point provide a practical balance of control-loop performance, memory, and peripheral integration. USB and CAN support can reduce external component count in USB-connected control products and CAN-based industrial equipment. The two ADC channels and seven timers support sensor monitoring, timing, motor-control, and signal-generation functions, provided the selected peripheral pins and board-level analog circuitry are designed according to the manufacturer documentation.
Typical applications include USB-to-digital monitoring systems, CAN-connected industrial controllers, embedded instrumentation, automation boards, and compact motor-control or timing platforms. The 48-pin package provides access to the MCU's available I/O, power, ground, analog, and communication functions, but pin assignments and exposed-pad requirements must be checked against the official STM32F103VBH6 datasheet before PCB release.
A key design consideration is validating power, clock, decoupling, boot configuration, and signal routing on the selected board. Because the supplied verified data does not include complete electrical limits, pin names, or timing details, designers should not infer missing values; consult the manufacturer datasheet and package drawing for authoritative implementation requirements.
This page combines verified distributor and source information with practical application context, procurement data, and replacement-source guidance. It is intended to help engineers identify the correct STM32 MCU, compare compatible sourcing options, and move quickly to datasheet-driven design validation.

主な用途
STM32F103VBH6 の用途: 6 件s: USB-Connected Embedded Control, CAN-Based Industrial Monitoring, Data Acquisition and Instrumentation, Industrial Automation Controller, Motor Control and Timing Platform, Communication Gateway.
USB-Connected Embedded Control
The STM32F103VBH6 fits USB-connected monitoring and control products because the verified device description identifies USB support alongside a 72 MHz ARM Cortex-M3 core and 128 KB Flash. It can execute device firmware, sample control inputs, and manage a USB-connected peripheral function on one MCU. The USB interface still requires the correct board routing, connector protection, power design, and firmware support. The verified data does not include USB electrical timing or endpoint details, so those values must be taken from the manufacturer datasheet before layout release.
おすすめ
CAN-Based Industrial Monitoring
The STM32F103VBH6 is suitable for CAN-connected industrial monitoring because the verified specifications identify CAN support, a 72 MHz processing rate, and seven 16-bit timers. The MCU can manage sensor acquisition, timing functions, local control, and CAN communication within one embedded platform. A practical design may use a CAN transceiver, protection network, and isolated or non-isolated bus interface depending on the installation. Exact peripheral routing and electrical limits are not included in the supplied data and must be verified against the official package and datasheet documentation.
おすすめ
Data Acquisition and Instrumentation
The STM32F103VBH6 can serve as the control and processing MCU in compact data-acquisition equipment because it combines a 72 MHz Cortex-M3 core with two verified 12-bit ADC channels and 128 KB Flash. The two ADC channels can support analog measurement channels when paired with suitable input conditioning, while the high-speed core can handle sampling control and communications. The verified source describes the converters as 1 microsecond conversions, but does not provide input-range, accuracy, or sampling-network details; use the manufacturer datasheet for analog design values.
おすすめ
Industrial Automation Controller
The STM32F103VBH6 is appropriate for compact automation logic because its verified feature set includes 37 I/O ports, seven 16-bit timers, USB, and CAN. Those resources support digital input/output handling, periodic control functions, event timing, and communications in a single controller. The 48-pin VFQFPN package provides a higher pin count than smaller MCU packages, although exact alternate-function assignments are not included in the supplied verified data. Board design should therefore check pin multiplexing, level shifting, isolation, and actuator-driver requirements before committing the PCB.
おすすめ
Motor Control and Timing Platform
The STM32F103VBH6 can support motor-control and precision timing prototypes because the verified specifications identify seven 16-bit timers and a 72 MHz Cortex-M3 core. Timer resources can be used for pulse generation, input capture, output compare, and periodic control functions, while the MCU handles supervisory logic and communications. Actual motor-control suitability depends on pin assignment, timer capabilities, PWM frequency, current sensing, power-stage design, and firmware. Those details are not supplied here and must be validated from the STM32F103VBH6 datasheet and application documentation.
おすすめ
Communication Gateway
The STM32F103VBH6 is well matched to embedded communication gateways that need both serial connectivity and general-purpose processing. The verified device description identifies USB and CAN, while the 72 MHz Cortex-M3 core and 128 KB Flash provide room for protocol handling, configuration storage, and local control tasks. A gateway implementation may combine a USB host or device interface with a CAN interface and digital I/O. Since the supplied data does not specify transceiver requirements, ESD ratings, or protocol timing, the final design should use application guidance from the manufacturer and validate signal integrity with the selected board layout.

設計ノート
Design the STM32F103VBH6 supply around the verified 2 V to 3.6 V operating range. Place local decoupling capacitors close to the device power pins and provide adequate source current for the selected clock, ADC, USB, and CAN configurations. The supplied verified data does not include absolute maximum ratings, regulator requirements, or recommended capacitor values, so those values must be taken from the manufacturer datasheet rather than inferred.
Use the manufacturer VFQFPN-48 land pattern and verify all exposed-pad, thermal, and paste requirements before fabrication. Confirm pin multiplexing for USB, CAN, ADC, timers, boot functions, debug interfaces, and crystal or clock connections. Because the complete verified pinout was not included in the supplied data, do not release a PCB footprint from an aggregator diagram alone; cross-check the official package drawing and device datasheet.
For USB and CAN implementations, route interfaces according to the applicable device and transceiver guidance and keep sensitive analog and communication paths away from noisy switching nodes. The verified data confirms USB and CAN support but does not specify signal timing, transceiver part, impedance, or isolation requirements. Confirm those details in the manufacturer datasheet and interface-device documentation, then validate with board-level testing.
Do not assume that an STM32F103-family alternative is drop-in solely because the core or peripheral set appears similar. The supplied cross-reference results identify GD32F103 and other STM32F103 alternatives, but exact package pins, Flash capacity, clock behavior, electrical limits, and firmware compatibility require verification. Record the approved alternate MPN only after schematic, footprint, timing, and firmware review.
コンプライアンス情報
The verified STM32F103VBH6 source identifies the device as RoHS compliant. No verified REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statement was supplied.
