STM32F091VCT6 - 48MHz Cortex-M0 256KB MCU | STMicroelectronics
부품 번호: STM32F091VCT6 ✓ 활성STM32F091VCT6 개요
A microcontroller is a programmable integrated circuit that combines a processor core, nonvolatile program memory, working memory, peripherals, and communication interfaces on one device. The STM32F091VCT6 belongs to STMicroelectronics' STM32F0 access-line family, where the ARM Cortex-M0 core provides a compact architecture for cost-sensitive embedded control. In the product hierarchy, it is a 32-bit microcontroller, embedded processor, and semiconductor intended for general-purpose industrial and consumer electronics.
Verified device features include a 48 MHz Cortex-M0 processor, 256 KB of flash organized as 256K by 8 bytes, 32 KB of SRAM, a CRC calculation unit, and CAN connectivity. The 100-pin LQFP-100 package provides a large number of external connections compared with smaller 32-pin or 64-pin devices. This combination is useful when a design requires both substantial local memory and a broad selection of general-purpose I/O.
The Cortex-M0 core uses a 32-bit RISC architecture and operates from a 2 V to 3.6 V range. Flash retains programmed firmware when power is removed, while SRAM provides volatile working memory for stack, data, and runtime operations. The CRC unit supports data-integrity calculations, and the available CAN interface is valuable for industrial networking, vehicle subsystems, or embedded control networks requiring a standardized serial bus.
Typical applications include industrial automation controllers, CAN-connected equipment, building and access systems, motor-control supervisory logic, and consumer products with a substantial pin requirement. Designers can place the MCU between external sensors, communication transceivers, actuators, and power-conversion stages. The 100-pin package also offers a practical footprint for designs requiring several communications, timer, and general-purpose I/O resources.
The primary design consideration is pin and peripheral planning. Before assigning external circuitry, engineers should verify the complete pinout, alternate-function mapping, and electrical limits in the manufacturer documentation. The 2 V to 3.6 V operating range also requires attention to regulator headroom, input filtering, decoupling, and brownout behavior during power transitions.
This page combines verified manufacturer and distributor information with package details, pricing context, application guidance, and honest drop-in replacement analysis. The replacement search found one defensible same-package option; other packaging variants and differently pinned devices were intentionally excluded because they would not constitute qualified drop-in replacements.

일반적인 애플리케이션
STM32F091VCT6 적합 용도: 6 애플리케이션s: CAN-Connected Industrial Control, Building Access and Security Control, Motor and Power-System Supervision, Data Acquisition and Sensor Hub, Communication Gateway, Consumer Control and Interface Hub.
CAN-Connected Industrial Control
The STM32F091VCT6 fits industrial supervisory controllers that require deterministic control logic and a CAN network interface. Its 48 MHz ARM Cortex-M0 core handles protocol and application tasks, while 256 KB of flash provides room for firmware and parameter data and 32 KB of SRAM supports working memory. A CAN transceiver can connect the MCU to the physical bus. Designers should verify bit-timing configuration, transceiver selection, termination, surge protection, isolation requirements, and fault behavior. The 100-pin LQFP package also provides access to a broad set of general-purpose and peripheral pins compared with smaller MCUs.
추천
Building Access and Security Control
The STM32F091VCT6 is suitable for access-control panels and security equipment that coordinate readers, locks, indicators, and networked supervisory functions. The 48 MHz Cortex-M0 core can execute protocol handling alongside control logic, while 256 KB of flash accommodates application firmware and 32 KB of SRAM handles runtime data. Its 100-pin LQFP footprint provides enough external connections for multiple digital inputs, outputs, and serial interfaces. Firmware designers should include authentication, safe lock release behavior, event logging, debounce handling, and watchdog recovery. Electrical interfaces should use appropriate protection rather than driving loads directly from MCU pins.
추천
Motor and Power-System Supervision
The STM32F091VCT6 can act as the supervisory controller in motor drives, battery systems, and industrial power modules. Its 48 MHz processing capability supports control loops, fault handling, and communication tasks, while 256 KB of flash and 32 KB of SRAM provide adequate resources for embedded software. The STM32F091VC device can monitor sensors, coordinate actuators, and communicate operating status over CAN. Designers should partition analog sensing from digital logic, use suitable gate drivers and isolation where required, and verify timing margins under worst-case load. The 2 V to 3.6 V operating range also makes regulated rail selection important.
추천
Data Acquisition and Sensor Hub
The STM32F091VCT6 works well as a central controller for sensor aggregation when a design requires more pins and memory than a compact microcontroller can offer. The 48 MHz Cortex-M0 core processes measurements and control data, 256 KB of flash stores firmware, and 32 KB of SRAM supports buffers and protocol state. The 100-pin LQFP package exposes a broad interface set for digital sensors, communications, and status signaling. Engineers should account for analog accuracy, reference stability, sensor settling time, grounding, and digital isolation. Software should also distinguish safety-critical measurements from ordinary control data and validate bus transactions before acting on them.
추천
Communication Gateway
The STM32F091VCT6 can bridge or monitor communications in compact embedded gateways where CAN, serial connectivity, and local control must coexist. The 48 MHz Cortex-M0 core supports message processing, while 256 KB of flash accommodates protocol stacks and configuration data and 32 KB of SRAM supports active communication buffers. Its 100-pin LQFP package offers more peripheral options than smaller STM32F0 devices. A gateway implementation should define protocol timeouts, nonvolatile configuration storage, watchdog behavior, and upgrade procedures. When used near motors or long wiring runs, surge protection and galvanic isolation may be required even if the MCU itself operates from a regulated 3.3 V rail.
추천
Consumer Control and Interface Hub
The STM32F091VCT6 is applicable to consumer products with several buttons, indicators, sensors, and serial interfaces requiring a consolidated controller. The 48 MHz ARM Cortex-M0 core provides responsive control, 256 KB of flash supports application code and data, and 32 KB of SRAM accommodates protocol and UI state. The LQFP-100 package provides more I/O than small packages while remaining broadly manufacturable. Design teams should still minimize external component count and consider a smaller MCU if only a few connections are needed. Firmware should include input debounce, robust state recovery, and brownout-aware behavior because consumer products may experience wide input-transient conditions.

설계 노트
Design the supply for the 2 V to 3.6 V operating range and include local high-frequency decoupling close to the device supply pins. The supplied data confirms 2.5 V and 3.3 V nominal arrangements but does not provide a complete regulator design. Verify startup sequencing, brownout behavior, and the current budget of every attached peripheral rather than sizing the supply from the MCU nameplate alone.
The 100-pin LQFP-100 package has 0.5 mm-class lead spacing and requires careful PCB footprint creation, solder-paste control, and reflow-profile validation. Follow the official ST package drawing for land pattern and exposed-pad requirements. Place decoupling and support components close to their associated pins, keep sensitive analog routes away from switching nodes, and provide adequate thermal copper where the selected board construction requires it.
Do not infer pin functions from the order code or rely on a generic STM32F0 pinout. Verify every numbered pin, alternate function, supply connection, and debug interface against the official STM32F091VCT6 documentation. Also confirm the distinction between the T6 and T7 temperature-grade suffixes before substitution. A package-compatible part can still be unsuitable if its environmental grade, lifecycle status, or approved supply differs.
For CAN or other communication interfaces, separate transceiver routing from sensitive control signals and follow the transceiver and MCU grounding guidance. Keep bus traces short where practical, provide the required termination only at designated bus ends, and add protection appropriate to the installation environment. Firmware should include bus-off recovery, timeout handling, and safe output states so a network fault cannot propagate into hazardous actuator behavior.
규정 준수 정보
The supplied manufacturer and distributor excerpts do not explicitly state the target part's compliance status, so no compliance claim has been inferred. Compliance declarations should be confirmed from the applicable STMicroelectronics product documentation before procurement.
