STM32F091VCH6 - 48MHz Cortex-M0 MCU with 256KB Flash | STMicroelectronics
MPN： STM32F091VCH6 ✓ 啟用中STM32F091VCH6 概覽
A microcontroller is a semiconductor that integrates a CPU core, program memory, data memory, peripherals, and communication interfaces on one die. Within the product hierarchy, the STM32F091VCH6 is an ARM Cortex-M0 microcontroller, an embedded MCU, and a member of STMicroelectronics' STM32F0 mainstream access family. Its combination of a 48 MHz processor, 256 KB Flash, and extensive peripheral integration supports control-oriented products requiring more capability than very small general-purpose MCUs.
Key features identified in the available manufacturer and distributor data include a 32-bit ARM Cortex-M0 core, 48 MHz maximum CPU frequency, 256 KB Flash, CAN support, 12 timers, a 12-bit ADC, a DAC, and communication interfaces. The 100-UFBGA package uses a 7 x 7 mm footprint, making the device suitable for space-constrained boards where a larger leaded or quad-flat package would be inconvenient.
The STM32F091VCH6 combines a general-purpose Cortex-M0 processing core with dedicated peripherals for analog measurement, signal generation, timing, and serial communication. Two independent 12-bit converters—one ADC and one DAC—allow a controller to acquire sensor data and generate analog output. The CAN interface supports industrial communication designs where a wired network is preferable to a general-purpose serial interface.
Typical applications include industrial sensor controllers, building automation equipment, motor and actuator control, CAN-connected embedded nodes, compact data-acquisition systems, and low-cost consumer devices. Its 256 KB Flash provides room for a bootloader and application firmware, while the 48 MHz CPU supports responsive control loops and communication service tasks.
Designers should confirm the exact 100-UFBGA land pattern, exposed-pad requirements, pin multiplexing, and decoupling recommendations against the manufacturer datasheet before layout. Firmware should also account for STM32F0 peripheral behavior, clock configuration, and the operating-voltage limits rather than assuming compatibility with other STM32 families.
This product page consolidates verified distributor specifications, application guidance, sourcing information, and strict drop-in replacement analysis. It also distinguishes confirmed same-footprint alternatives from merely similar MCUs, helping engineers avoid confusing electrical equivalence with true PCB-level replaceability.

典型應用
STM32F091VCH6 適用於 6 應用s: CAN-Connected Industrial Sensor Controller, Compact Data-Acquisition Module, Building Automation Controller, Motor and Actuator Control Node, Automated Test and Measurement Equipment, Low-Cost Connected Consumer Device.
CAN-Connected Industrial Sensor Controller
The STM32F091VCH6 fits a CAN-connected industrial sensor controller because it combines a 48 MHz Cortex-M0 core, 256 KB Flash, a 12-bit ADC, and hardware CAN support. The microcontroller can acquire sensor inputs, execute control and filtering routines, and exchange status data over a robust industrial network. Its 100-UFBGA package is only 7 x 7 mm, leaving board area for sensors and analog front-end components. Designers should pair the MCU with a suitable CAN transceiver, protected bus interface, proper termination, and verified decoupling, while treating the 2.0 V to 3.6 V operating range as the basis for power-supply design.
Compact Data-Acquisition Module
The STM32F091VCH6 is appropriate for a compact data-acquisition module where a 12-bit ADC, 48 MHz processing speed, and limited board area are important. It can sample multiple analog inputs, scale and filter readings, store operational data in its 256 KB Flash, and expose results through its communication interfaces. The 100-UFBGA 7 x 7 mm package supports dense instrumentation without using a large leaded package. Accurate analog results still depend on the selected ADC input architecture, reference quality, source impedance, sampling time, layout separation, and calibration strategy described in the complete manufacturer documentation.
Building Automation Controller
The STM32F091VCH6 can serve as a building-automation controller because its 48 MHz Cortex-M0 core provides useful control throughput, while 12 timers support periodic sensing and switching functions. The 256 KB Flash is sufficient for structured embedded application code, and the ADC can monitor environmental or occupancy-related analog sensors. CAN connectivity enables integration into wired building networks when the system architecture requires it. For reliable deployment, include watchdog and brownout strategies, carefully isolate noisy relays from analog circuitry, and validate the final controller against the required environmental and network specifications.
Motor and Actuator Control Node
The STM32F091VCH6 is suitable for a distributed motor or actuator control node that must combine deterministic timing, analog feedback, and network communications. Its 12 timers and 48 MHz Cortex-M0 core support PWM generation, input capture, scheduling, and control-loop execution, while the 12-bit ADC can read position or current-sense signals. The 12-bit DAC can provide an analog reference or bias output where the application requires it. Exact timer channels, trigger mappings, motor-control peripherals, and electrical limits must be confirmed from the manufacturer datasheet before assigning these functions to pins.
Automated Test and Measurement Equipment
The STM32F091VCH6 fits automated test and measurement equipment that requires an embedded controller with moderate compute capacity, flexible analog interfaces, and a small footprint. Its 48 MHz Cortex-M0 core can coordinate acquisition sequences and control peripheral hardware, while the 12-bit ADC and DAC support signal conditioning, stimulus generation, or test-point control. The 256 KB Flash provides room for configuration data and firmware in many compact instruments. For high-accuracy or high-rate measurements, verify the ADC acquisition architecture and external analog components rather than inferring performance from the 12-bit resolution alone.
Low-Cost Connected Consumer Device
The STM32F091VCH6 can support a low-cost connected consumer device that needs more local control capability than a very basic microcontroller. Its 256 KB Flash and 48 MHz Cortex-M0 core can manage user interactions, sensors, local logic, and communication tasks, while CAN provides a wired option for accessories or an embedded control network. The 7 x 7 mm 100-UFBGA package helps reduce board size. Designers should assess boot time, firmware update strategy, peripheral usage, production programming, and the absence of verified wireless connectivity before choosing this MCU for a directly connected consumer product.

設計說明
Do not create the 100-UFBGA footprint from the distributor description alone. Download the manufacturer package drawing and use its ball map, pitch, solder-mask data, and exposed-pad recommendation to verify every land pattern. The available information confirms a 7 x 7 mm package but does not provide a complete pin table, so pad numbering and ball assignments must be checked against the official documentation before fabrication.
Design the supply for the documented 2.0 V to 3.6 V operating range and confirm the exact power-pin and analog-supply requirements in the manufacturer datasheet. Place required bypass capacitors close to the relevant supply and ground balls, provide adequate source current for the 48 MHz operating condition, and separate analog returns carefully where the application includes sensitive ADC measurements.
Do not treat another STM32F0 or STM32F1 MCU as a drop-in replacement merely because it uses an Arm Cortex-M core and has similar memory. A valid substitution requires the same 100-UFBGA footprint, compatible ball assignments, equivalent power and ground connectivity, and matching peripheral functions. The supplied cross-reference results did not verify those requirements for a candidate, so board reuse must wait for a package and pinout comparison.
Keep the compact 7 x 7 mm MCU layout orderly by assigning continuous ground connectivity, minimizing return-path interruptions, and placing decoupling before nearby high-di/dt circuitry. If the device controls relays, motors, or other inductive loads, keep switching current paths away from the MCU and analog section. Review the official recommended PCB layout and unused-ball guidance before finalizing signal assignments.
