N.º de pieza: STM32F301K8U6 ✓ ActivoSTM32F301K8U6 Descripción general
A microcontroller is a programmable system-on-chip that integrates a CPU, memory, peripherals, and interface logic into one package. The STM32F301 belongs to the STM32F3 family of mainstream mixed-signal microcontrollers. Its Cortex-M4 core combines a 32-bit RISC architecture with single-cycle multiplication, hardware division, DSP instructions and an FPU, placing it above basic Cortex-M devices in computational and signal-processing capability.
The STM32F301K8U6 combines 72 MHz processing with 64 KB of Flash and 16 KB of SRAM in a compact 32-pin UFQFPN package. This combination makes it useful for control systems that need responsive task execution without requiring a larger external-memory interface. The on-chip CRC unit provides an efficient way to detect transmission or storage errors, while the DSP instruction set and FPU improve the suitability of the device for digital filtering, control calculations and other mixed-signal workloads.
The STM32F301x6/8 family architecture is centered on the Arm Cortex-M4 core, with the F301K8U6 configuration providing 64 KB of Flash and 16 KB of SRAM. Single-cycle multiplication and hardware division reduce instruction overhead in control and signal-processing loops. Compared with a general-purpose host processor, this dedicated microcontroller combines deterministic embedded execution with a compact package and integrated peripherals, while the 72 MHz operating limit defines the maximum supported core clock.
Typical uses include industrial motor and motion control, compact sensor modules, digital power controllers, communication equipment and low-cost mixed-signal instruments. The 64 KB Flash capacity can store a focused application rather than a large operating system, while the Cortex-M4 FPU supports arithmetic-heavy control algorithms. The 32-pin UFQFPN package is particularly useful where board space is constrained but a full-featured 32-bit embedded processor is required.
Designers should verify the complete pin assignment, power requirements, clock configuration, decoupling network and peripheral multiplexing against the manufacturer documentation before layout. Because the supplied product data confirms a 32-pin UFQFPN package but does not provide a complete public pin table, the package drawing and pin definitions should be checked directly in STMicroelectronics documentation. Firmware migration should also be reviewed for peripheral-instance and register differences within the STM32F301 family.
This product record combines verified manufacturer and distributor information with package-focused selection guidance, sourcing questions, application-fit analysis and explicit identification of unavailable technical and pricing fields. It is intended to help engineers establish whether the STM32F301K8U6 matches their processing, memory, package and procurement requirements without implying that unverified electrical details or drop-in alternatives are available.

Aplicaciones típicas
STM32F301K8U6 es adecuado para 6 aplicacións: Industrial Motor Control, Digital Power Control, Sensor Signal Conditioning, Communication Equipment, Digital Audio and Signal Processing, Compact Embedded Control Module.
Industrial Motor Control
The STM32F301K8U6 fits compact motor-control and actuator-control systems where a 72 MHz Cortex-M4 core can execute control calculations within a short response interval. Its integrated FPU, DSP instructions, hardware division and single-cycle multiplication are useful in algorithms involving proportional-integral-derivative control, transforms and signal conditioning. The 64 KB of Flash supports a dedicated control application, while 16 KB of SRAM provides working memory for control state and data paths. The 32-pin UFQFPN 5 x 5 mm package also helps reduce board footprint. Final suitability depends on confirming the required PWM channels, ADC characteristics, timer resources and pin multiplexing against the current STMicroelectronics documentation.
Digital Power Control
The STM32F301K8U6 is appropriate for small digital power controllers that need fast mixed-signal computation in a limited board area. Its Cortex-M4 processor can run at up to 72 MHz, and the FPU, DSP instructions and hardware division support compensation, filtering and transform calculations more efficiently than a basic 8-bit controller. With 64 KB of Flash and 16 KB of SRAM, the device can hold focused firmware without external program memory in many designs. The compact 32-pin UFQFPN package can shorten routing to dense power components. Before selecting it, verify ADC resolution, sampling behavior, PWM resources, compensation-loop timing and the required operating-voltage range.
Sensor Signal Conditioning
The STM32F301K8U6 can serve as the processing engine in a compact sensor-conditioning module that must filter measurements and present computed results through embedded interfaces. The 72 MHz Cortex-M4 core with an FPU supports digital filtering and floating-point compensation, while the CRC calculation unit can protect transferred data against corruption. Its 64 KB Flash and 16 KB SRAM are suitable for a focused acquisition and processing application rather than a large connectivity stack. The 32-pin UFQFPN package preserves PCB area in densely populated instrumentation. Exact ADC, communication-interface and pin-assignment requirements must be checked because the verified source information does not provide those electrical details.
Communication Equipment
The STM32F301K8U6 is suitable for protocol-handling and communication-support functions where deterministic 32-bit embedded processing is needed without a large host processor. At up to 72 MHz, the Cortex-M4 can service interrupts, maintain communication state and perform CRC calculations efficiently, while the DSP instruction set can support framed-data processing. The 64 KB Flash configuration can hold a focused networking or fieldbus application, and 16 KB of SRAM can support transmit and receive buffers. The compact 5 x 5 mm UFQFPN package is useful in communication modules with limited board area. Verify the exact UART, SPI, I2C, USB and CAN resources, plus their alternate-function pins, before finalizing the design.
Digital Audio and Signal Processing
The STM32F301K8U6 can support compact digital audio or general signal-processing tasks that benefit from a Cortex-M4 FPU and DSP instructions at up to 72 MHz. Single-cycle multiplication and hardware division improve the execution efficiency of filters, equalization and other arithmetic-intensive routines. Its 64 KB of Flash stores a dedicated firmware image, while the 16 KB SRAM supports sample buffers and working state in small applications. The 32-pin UFQFPN package can also be integrated into compact audio modules. The device should not be assumed to include a specific audio interface or sufficiently high ADC and DAC performance without consulting the full manufacturer datasheet; clocking, codec connectivity and real-time timing remain key design checks.
Compact Embedded Control Module
The STM32F301K8U6 works well as the central controller in a compact embedded module where 32-bit arithmetic, moderate program memory and low board area are the main priorities. Its 72 MHz Cortex-M4 core provides substantially more processing headroom than an 8-bit MCU, while 64 KB of Flash and 16 KB of SRAM fit many focused control, monitoring and configuration applications. The 32-pin UFQFPN 5 x 5 mm package simplifies miniaturization and can reduce lead-routing pressure on dense boards. The integrated CRC unit supports data-integrity checks in distributed systems. For deployment, verify reset and boot behavior, clock sources, supply requirements, debug access and peripheral pin assignments using the current STMicroelectronics documentation.

Notas de diseño
Use the current STMicroelectronics UFQFPN-32 land pattern and pin table rather than inferring connections from the package name. The verified data confirms a 32-pin 5 x 5 mm UFQFPN package, but it does not supply the numbered pins, exposed-pad treatment or recommended PCB geometry. Check the official package drawing and footprint carefully, especially for thermal-via requirements and exposed-pad connectivity.
Confirm the device's exact supply-voltage limits and power-consumption figures in the manufacturer datasheet before designing the regulator and decoupling network. The verified source material confirms the 72 MHz Cortex-M4 core, 64 KB Flash and 16 KB SRAM but does not provide operating-voltage or current specifications. Apply the datasheet's recommended input and bulk capacitors, and account for higher clock-dependent dynamic current when validating the power source.
Do not treat STM32F301K6T6 as a drop-in replacement merely because both devices use a 32-pin package designation. The supplied comparison identifies 32 KB rather than 64 KB of Flash for STM32F301K6T6 and associates it with LQFP instead of the target's UFQFPN footprint. Verify package dimensions, pinout, memory requirements, peripherals and firmware assumptions independently before approving any substitution.
Plan the PCB for the MCU's high-speed clock, debug and communication functions using the current manufacturer layout guidance. Keep the supported decoupling capacitors close to their associated supply pins, provide a clean return path beneath signal-routing areas where recommended, and isolate analog and digital return currents appropriately. The supplied data does not specify pin assignments, so no exact capacitor or routing value should be assumed.
Información de cumplimiento
The verified STM32F301K8U6 product and distributor snippets do not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free or conflict-minerals declarations. These statuses remain unknown until confirmed for the exact orderable MPN through current STMicroelectronics compliance documentation.
