STM32F103VDH6TR - 72MHz Cortex-M3 384KB MCU | STMicroelectronics (Tape & Reel)
MPN: STM32F103VDH6TR ✓ ActiveSTM32F103VDH6TR Overview
A microcontroller is a programmable semiconductor that combines a processor core, memory, peripherals, and communication interfaces on one integrated circuit. The STM32F103VDH6TR is an Arm Cortex-M3 microcontroller, placing it in the embedded processor hierarchy below application-specific MCUs while above general-purpose logic devices. Its combination of substantial Flash storage, numerous serial interfaces, and a high pin count supports complex control, communication, acquisition, and motor-control designs.
Key features include the Cortex-M3 core operating at up to 72 MHz, 384 KB of Flash, USB and CAN connectivity, 11 timers, three analog-to-digital converters, and 13 communication interfaces. The high-density pin count provides access to these resources and supports integration with sensors, actuators, communication transceivers, and human-machine-interface electronics. The supplied listings identify the device as a 3.3 V, 100-LFBGA microcontroller.
The STM32F1 architecture is suited to real-time embedded applications requiring deterministic peripheral access and a broad peripheral set. Multiple timers support motor-control, timing, and PWM tasks, while USB and CAN provide paths for host connectivity and industrial network communication. Three ADCs permit multiple analog input channels to be evaluated within the same control system, although detailed resolution, sampling rate, and channel mapping require confirmation in the manufacturer documentation.
Typical applications include industrial automation controllers, USB-connected data-acquisition equipment, CAN-based motor systems, communication gateways, and compact embedded control platforms. Its 384 KB Flash capacity can hold a substantial firmware image, while the available USB, CAN, timer, and ADC resources reduce the need for external peripheral devices in designs that can operate from a single 3.3 V MCU.
Designers must confirm the exact pin assignment, exposed-pad connection, decoupling requirements, clock configuration, and peripheral electrical limits in the STM32F103VD datasheet. The 100-ball BGA also requires assembly capability capable of handling the 10 mm by 10 mm land pattern and its fine-pitch ball array, so prototype assembly and production inspection should be considered before layout release.
This page consolidates verified manufacturer and distributor information with application guidance, sourcing context, and an explicit distinction between the BGA target and incompatible alternative packages. It avoids presenting cross-package functional substitutes as drop-in replacements and identifies every unavailable engineering parameter that still requires datasheet confirmation.

Typical Applications
STM32F103VDH6TR is suitable for 6 applications: USB Data-Acquisition Controller, CAN-Based Industrial Control Module, Motor Control and PWM Platform, Embedded Communication Gateway, Instrumentation and Sensor Hub, Human-Machine Interface Controller.
USB Data-Acquisition Controller
The STM32F103VDH6TR fits USB-connected acquisition equipment because its 384 KB Flash supports a substantial firmware image while the Cortex-M3 core handles protocol processing and control logic at up to 72 MHz. The three ADCs provide multiple analog input channels, and USB permits a direct host interface without a separate USB controller. A practical design would place the MCU close to the analog section, keep sensitive analog routing away from digital switching paths, and confirm the required ADC accuracy and sampling rate against the manufacturer datasheet.
Recommended
CAN-Based Industrial Control Module
The STM32F103VDH6TR is appropriate for CAN-connected industrial control because the verified feature set includes CAN, 11 timers, three ADCs, and 13 communication interfaces. Its 72 MHz Cortex-M3 core can supervise actuators while timers handle periodic tasks and the ADC channels monitor process variables. The design must use an external CAN transceiver for physical-layer implementation, isolate field wiring according to the installation requirements, and validate bus timing, termination, protection, and environmental operation before deployment.
Recommended
Motor Control and PWM Platform
The STM32F103VDH6TR supports compact motor-control and PWM platforms through its 11 timers, 72 MHz processing capability, three ADCs, and broad I/O count in the 100-LFBGA package. Timers can generate control and PWM signals while ADC channels can sample command or feedback inputs. The MCU is not a substitute for a high-current motor driver or power stage; those functions require appropriately rated external components, protection, current sensing, and thermal design based on the motor and supply specifications.
Recommended
Embedded Communication Gateway
STM32F103VDH6TR can serve as a communication gateway because its 13 communication interfaces, 384 KB Flash, and 72 MHz Cortex-M3 core allow protocol handling, local configuration, and status monitoring in one device. USB and CAN provide two useful connectivity paths for configuration, service access, and industrial networking. Gateway firmware should use explicit buffer limits, watchdog recovery, secure boot and update procedures where required, and careful isolation between external interfaces and exposed connectors.
Recommended
Instrumentation and Sensor Hub
The STM32F103VDH6TR suits instrumentation and sensor-hub designs requiring three ADCs, numerous timers, and multiple serial interfaces in a compact 100-ball package. The processor can coordinate measurements, apply calibration, timestamp events, and publish results through USB or CAN. Analog front-end design remains critical: input ranges, source impedance, acquisition time, reference accuracy, and grounding determine usable ADC performance and must be evaluated from the manufacturer electrical characteristics before selecting external signal-conditioning components.
Recommended
Human-Machine Interface Controller
The 100-pin STM32F103VDH6TR provides the I/O and peripheral density needed to coordinate buttons, indicators, displays, encoders, and communication links in a compact embedded human-machine interface. Its 384 KB Flash and 72 MHz core provide capacity for display updates, input handling, and local diagnostics. Layout should separate slow or noisy display and connector signals from sensitive analog inputs, while firmware should include debouncing, fault reporting, and safe behavior during display or communications failures.

Design Notes
Treat the 100-LFBGA layout as an advanced assembly design rather than a conventional leaded-package board. Verify courtyard dimensions, ball pitch, solder-mask and paste patterns, via-in-pad policy, and exposed-pad connection against the official STM32F103VD package drawing. Prototype using an assembly process qualified for the package, and inspect the fine-pitch ball array electrically and optically before applying conformal coating.
Provide a clean 3.3 V supply and follow the manufacturer's input, output, decoupling, and exposed-pad requirements exactly. Place bulk and high-frequency decoupling capacitors close to their associated supply balls, maintain a low-impedance return path, and keep switching-node or high-current routing away from sensitive analog inputs. Because detailed current limits and capacitor values were not included in the verified snippets, engineers must obtain them from the manufacturer datasheet before releasing the power network.
Partition analog, digital, clock, and high-speed communication routing to reduce coupling into the three ADC channels. Use a continuous ground reference, avoid routing analog inputs beneath digital or switching paths, and place precision analog components close to their MCU pins. If USB or CAN interfaces are used, follow the applicable reference layout and impedance guidance from the manufacturer rather than relying on generic routing dimensions.
Do not treat LQFP-100 STM32F103 or GD32F103 candidates as physical drop-ins for the 100-LFBGA target. The cited GD32F103VDT6 is a related 72 MHz-to-108 MHz comparison candidate but uses LQFP, so its board footprint and pin functions must be reworked and its firmware timing revalidated. Also avoid assuming that the H in the order code alone authorizes automotive use; verify the exact qualification and environmental declarations.
Compliance Information
The supplied verified search results do not explicitly state compliance status for the exact STM32F103VDH6TR order code. Consult current STMicroelectronics product and material-compliance documentation before qualification.
