STM32F031K6T6 - 48MHz Cortex-M0 MCU | STMicroelectronics
Référence : STM32F031K6T6 ✓ ActifSTM32F031K6T6 Présentation
A microcontroller is a programmable system-on-chip that combines a processor core, nonvolatile program memory, volatile data memory, peripherals, and general-purpose I/O in one package. The STM32F031 belongs to the STM32F0 access-line family, where ARM Cortex-M0 -> 32-bit RISC microcontroller -> embedded microcontroller -> semiconductor forms the relevant product hierarchy. Its compact package and mixed-signal peripherals suit cost-sensitive embedded-control products that require deterministic control without a higher-performance MCU.
Key features include a 48 MHz ARM Cortex-M0 core, 32 KB of Flash for firmware storage, and 4 KB of SRAM for working memory. The 12-bit ADC supports analog measurement, while the I2C, SPI/I2S, and USART interfaces cover sensor buses, serial peripherals, and point-to-point communication. Nine timers support periodic and timing functions, and the 2.0 V to 3.6 V operating range permits integration with common 3.3 V embedded systems.
The STM32F031K6 architecture emphasizes compact control rather than high-performance computation. Its 32-bit Cortex-M0 instruction set provides efficient control-loop execution, while the integrated analog and serial peripherals reduce the need for external components. Available SRAM and Flash should be checked against the final application, particularly when buffering samples, maintaining protocol stacks, or supporting bootloader features.
Typical applications include compact sensor controllers, small motor-control systems, industrial monitoring nodes, digital control modules, battery-powered instruments, and communication equipment. The STM32F031K6T6 is particularly relevant where 48 MHz processing, 25 I/Os, and multiple serial interfaces are required within a 32-LQFP footprint.
Designers should verify the exact pin assignment, alternate-function requirements, decoupling network, clock configuration, and peripheral instance mapping against the manufacturer datasheet. The 2.0 V minimum supply imposes a 3.3 V rail design constraint, and firmware should include reset, clock, ADC-calibration, and brownout handling appropriate to the selected power architecture.
This page consolidates the verified manufacturer specifications, distributor availability references, cross-reference evidence, and engineering guidance into a structured selection resource. It distinguishes verified drop-in evidence from generic MCU alternatives and highlights the limits of using an unqualified third-party replacement in production.

Applications typiques
STM32F031K6T6 convient pour 6 applications: Industrial Sensor Controller, Compact Motor and Actuator Control, Low-Power Data Logger, Serial Communication Gateway, Battery-Powered Instrument, Embedded Control Module.
Industrial Sensor Controller
The STM32F031K6T6 fits compact industrial sensor modules that must acquire analog measurements, process them locally, and forward data through a serial link. Its 12-bit ADC supports measurement tasks, while the I2C interface can connect compatible sensors and the USART or SPI/I2S interface can provide system connectivity. With a 48 MHz Cortex-M0 core, 32 KB of Flash, 4 KB of SRAM, and 25 I/Os, it offers enough resources for acquisition, filtering, threshold logic, and communications. Designers should add the required input protection, calibration path, watchdog policy, and industrial environmental qualification at the system level.
Recommandé
Compact Motor and Actuator Control
The STM32F031K6T6 is appropriate for small motor, solenoid, or actuator controllers where deterministic timing, local feedback, and limited board area are important. Its nine timers and 48 MHz Cortex-M0 core can support configurable PWM and periodic control functions, while the 12-bit ADC provides a path for analog feedback measurement. Twenty-five I/Os leave room for gate-control signals, position inputs, and communications. The MCU is not a substitute for external power-stage protection, so current sensing, flyback paths, thermal monitoring, and fault shutdown must be designed around the load.
Recommandé
Low-Power Data Logger
The STM32F031K6T6 can serve as the control MCU in a compact data logger that periodically samples sensors, stores limited local data, and reports results through a low-speed interface. Its 32 KB of Flash provides room for firmware and configuration, while 4 KB of SRAM supports buffering and working state. The nine timers help organize acquisition and logging intervals, and the I2C interface can connect suitable sensors. A practical design should use the exact low-power behavior documented for the selected device, minimize always-on peripherals, and account for the 2.0 V to 3.6 V supply range.
Recommandé
Serial Communication Gateway
The STM32F031K6T6 fits a compact protocol-conversion or communications gateway requiring USART, SPI/I2S, and I2C interfaces on one controller. The 48 MHz Cortex-M0 core can manage framing and protocol state, while 32 KB of Flash holds application firmware and 4 KB of SRAM supports temporary buffers. Twenty-five I/Os provide logic-level channels for converters and status indicators. Designers should verify the exact peripheral instance and alternate-function mapping for each package pin, isolate external connectors where required, and validate baud-rate, buffering, and fault-recovery behavior under sustained traffic.
Recommandé
Battery-Powered Instrument
The STM32F031K6T6 can control a small battery-powered instrument that combines analog measurement, timed operation, and a simple user interface. Its 12-bit ADC supports sensor acquisition, its timers support periodic measurement and control, and the 2.0 V to 3.6 V operating range supports low-voltage embedded systems. The 32-LQFP 7 x 7 mm package helps limit board area, although energy efficiency depends on the complete clock, peripheral, and sleep-mode design. Battery protection, regulator selection, leakage analysis, and the device-specific low-power limits must be validated before deployment.
Recommandé
Embedded Control Module
The STM32F031K6T6 is well matched to compact embedded-control modules that coordinate sensors, timers, and serial peripherals while retaining a simple 32-LQFP footprint. Its 48 MHz Cortex-M0 core, nine timers, 25 I/Os, and three principal serial-interface types provide a practical baseline for control logic, status reporting, and firmware updates. The 32 KB Flash and 4 KB SRAM encourage disciplined resource allocation, particularly for protocol stacks or data logging. A production module should define brownout handling, bootloader behavior, debug access, clock startup, and field-update requirements against the official datasheet.

Notes de conception
Design the power rail for the verified 2.0 V to 3.6 V operating range and place the required local decoupling close to the supply and ground pins. Use the exact capacitor values and layout guidance in the STMicroelectronics datasheet rather than relying on generic values. Brownout behavior, startup current, and regulator quiescent current must be checked together, particularly if the controller operates from a small battery or a shared 3.3 V rail.
Confirm the complete 32-LQFP pin table, alternate-function assignments, and exposed thermal-pad requirements directly from the STM32F031K6 datasheet before routing. Place SWD programming access, reset support, clock components, and decoupling where they remain accessible after assembly. Because the supplied excerpt does not provide the numbered pinout, do not derive board connections from package position alone; verify every net against the manufacturer diagram.
Do not assume that a third-party pin-compatible MCU is a drop-in replacement without reviewing its electrical limits, memory map, clock startup, interrupt vector behavior, peripheral registers, and development-tool support. The supplied HK32F031K6T6 cross-reference explicitly calls compatibility conditional. Validate bootloader, timing, ADC accuracy, communication interoperability, and environmental requirements before approving it for production.
Keep analog inputs away from fast digital edges and switching-supply return currents, and route ADC inputs with short traces over a continuous ground plane. If the ADC measures low-level signals, use the datasheet-recommended source impedance and sampling time rather than assuming the maximum clock rate applies to every channel. Firmware should also reject or average samples that fall outside expected sensor bounds.
Plan the LQFP footprint for assembly and inspection, including adequate pin-1 orientation marking, solderable exposed-pad geometry if applicable, and a land pattern verified against the package drawing. Place input and output filtering near the associated pins, separate potential clock and communication routes from sensitive analog nodes, and provide test points for supply, reset, and debug. These measures reduce rework risk on a compact mixed-signal control board.
Informations de conformité
The supplied verified excerpts do not explicitly state the target's RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or package type.
