STM32F103VCH6 - 72MHz Cortex-M3 MCU | STMicroelectronics
部品番号: STM32F103VCH6 ✓ 生産中STM32F103VCH6 概要
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, and peripherals such as timers, communication interfaces, and analog conversion blocks into one device. The STM32F1 family hierarchy includes the STM32 microcontroller product type, the STM32F1 series, the Performance Line, and the high-density STM32F103 platform. Within the broader semiconductor category, this device combines general-purpose control processing with dedicated embedded peripherals on a single IC.
The verified product information identifies a 72 MHz ARM Cortex-M3 core, 32-bit RISC architecture, 256 KB flash organized as 256K x 8 bits, and a 100-LFBGA package. The STM32F1 Performance Line family is also described as supporting USB, CAN, 11 timers, three ADCs, and 13 communication interfaces. These resources support designs that combine control-loop processing with multiple external communication channels and analog measurements.
At the architecture level, the Cortex-M3 processor provides a 32-bit execution environment suitable for embedded control, while the STM32F103 peripheral set integrates timing, conversion, and communications functions around that core. A 10 x 10 mm LFBGA substantially reduces PCB area compared with leaded packages, but it also requires careful PCB layout, fine-pitch assembly, and inspection because component pads cannot be visually inspected from the board edge.
Typical applications include industrial controllers, CAN-connected motor equipment, USB-enabled data acquisition systems, communication gateways, and compact embedded instruments. The 100-pin package provides a high pin count for systems that need numerous external connections, while 256 KB of flash accommodates firmware, configuration data, and application routines. Its 72 MHz maximum frequency also provides useful control-loop and communications headroom.
Designers should allocate the PCB footprint for the exact 100-LFBGA arrangement, verify the electrical requirements for every populated ball, and validate decoupling, clock, reset, and programming access. Because the verified snippets do not provide a complete public pin table, the pinout is left unpopulated rather than inferred. Firmware and board bring-up should also account for the STM32F103-specific startup sequence and peripheral configuration.

主な用途
STM32F103VCH6 の用途: 6 件s: CAN-Connected Industrial Control, USB Data-Acquisition Controller, Compact Motor-Control Controller, Communication Gateway and Protocol Hub, Embedded Measurement and Control Instrument, IoT Sensor and Automation Node.
CAN-Connected Industrial Control
The STM32F103VCH6 fits CAN-connected industrial controllers because its verified STM32F1 Performance Line feature set includes CAN, 11 timers, three ADCs, and 13 communication interfaces. The 72 MHz ARM Cortex-M3 core can execute control logic and communication tasks while the 256 KB flash stores application firmware, configuration, and diagnostic data. In a typical implementation, the MCU operates at 3.3 V, generates timer references for motor or actuator control, samples analog inputs through an ADC, and exchanges state through an external CAN transceiver. The 100-LFBGA package reduces board area, although fine-pitch assembly and careful decoupling are required.
おすすめ
USB Data-Acquisition Controller
The STM32F103VCH6 is appropriate for a compact USB data-acquisition controller because the verified feature set includes USB, three ADCs, and a 72 MHz Cortex-M3 processor. The MCU can acquire analog measurements, execute filtering and scaling, and present data through a USB-compatible interface while its 256 KB flash holds firmware and calibration parameters. A 2.5 V or 3.3 V operating supply aligns with many compact embedded platforms, while the 100-pin package exposes more peripheral options than a low-pin-count MCU. Practical implementation still requires the exact USB transceiver and connector circuitry, clock validation, and careful analog-ground partitioning.
おすすめ
Compact Motor-Control Controller
The STM32F103VCH6 suits compact motor-control equipment because the 72 MHz Cortex-M3 core provides control-processing headroom, while the STM32F1 family includes 11 timers and three ADCs. Multiple timer channels can support motor timing, and the ADC channels can monitor command, feedback, or supply signals. Its 256 KB flash is suitable for a focused controller rather than a large graphical application, and the 10 x 10 mm LFBGA package helps reduce controller size. In a motor-control design, an external gate driver, power stage, current sensing network, and protection circuitry remain necessary, and motor-noise immunity must be validated before deployment.
おすすめ
Communication Gateway and Protocol Hub
The STM32F103VCH6 can serve as a compact communication gateway because the verified STM32F1 specification lists 13 communication interfaces, USB, CAN, and a 72 MHz processing core. That combination allows one MCU to translate or monitor data between field and host-facing links while executing protocol and diagnostic routines in 256 KB of flash. The 100-LFBGA package provides a high pin count for isolated interface domains, clocks, reset, and status signaling. In production, gateway designs should partition analog and digital grounds, apply appropriate level translation, and validate protocol timing under worst-case traffic and interrupt load.
おすすめ
Embedded Measurement and Control Instrument
The STM32F103VCH6 is well matched to embedded measurement equipment that combines analog acquisition with digital processing. Three family ADCs support analog measurement channels, the 72 MHz Cortex-M3 core can execute acquisition sequencing and calculation, and 256 KB flash can retain firmware, calibration tables, and instrument settings. The compact 100-LFBGA body is advantageous for portable or panel-mounted instruments where board area is constrained. Measurement accuracy still depends on the analog front end, reference strategy, grounding, filtering, and calibration; MCU specifications alone do not define input accuracy or equivalent noise performance.
おすすめ
IoT Sensor and Automation Node
The STM32F103VCH6 can act as a connected IoT or automation node because the STM32F1 family combines USB, CAN, 13 communication interfaces, 11 timers, and three ADCs around a 72 MHz Cortex-M3 core. These resources support periodic sensing, local filtering, actuator timing, and gateway communications while 256 KB flash accommodates firmware and configuration. The 2.5 V or 3.3 V supply range supports embedded power architectures, and the 10 x 10 mm LFBGA preserves board area. A practical node still needs sensor conditioning, a suitable communication transceiver, power regulation, and firmware updates through a secure production process.

設計ノート
Design the land pattern directly from the manufacturer drawing for the 100-LFBGA package and verify it against the PCB library rather than relying on the generic 10 x 10 mm body description. Confirm ball pitch, pad dimensions, solder-mask geometry, and exposed thermal or ground-ball requirements with the exact package drawing. A pad or ball-assignment error can create an open circuit that is difficult to diagnose after board assembly.
Follow the manufacturer requirements for supply voltage, decoupling, and power-up sequencing. The verified data confirms 2.5 V or 3.3 V operation but does not provide the complete pin-level power connection table, so the exact VDD, VSS, and decoupling requirements must be taken from the datasheet. Place required input and bulk capacitors close to their associated balls and provide clean return paths for high-current switching in the surrounding circuitry.
Preserve the 72 MHz system-clock and communications timing margin by following the STM32F103 clock, reset, and debug recommendations. Keep sensitive analog inputs away from USB, CAN, motor-drive, and high-current switching paths. Because the device includes three ADCs and multiple communication interfaces, partition analog and digital return currents carefully and validate grounding under real switching loads rather than only in a static laboratory setup.
Do not assume that another STM32F103 order code is interchangeable merely because its flash size or suffix differs. STM32F103VCH8 appears closest by configuration, while STM32F103VDH6 provides 384 KB rather than 256 KB flash. Before substitution, confirm the complete ball map, temperature grade, power pins, bootloader behavior, flash organization, timing, and peripheral configuration. Cross-brand GD32F103 candidates require separate firmware and timing validation.
コンプライアンス情報
The supplied product and distributor snippets do not explicitly state compliance status for the exact ordering code. Compliance documents must be obtained from STMicroelectronics or an authorized distributor rather than inferred from the STM32F1 family name.
