STM32F301C8T6 - 72MHz Cortex-M4 64KB MCU | STMicroelectronics
部品番号: STM32F301C8T6 ✓ 生産中STM32F301C8T6 概要
A microcontroller is a programmable system-on-chip that integrates a CPU, memory, peripherals, and interfaces onto one package. The STM32F301C8T6 belongs to the STM32F301 mixed-signal MCU family, with the STM32F3 series positioned between general-purpose embedded control and higher-performance Cortex-M applications. Its Arm Cortex-M4 architecture supports efficient real-time execution while the floating-point unit accelerates numeric and control workloads without requiring an external processor.
The verified device data identifies 64 KB of Flash, 16 KB of SRAM, a maximum operating frequency of 72 MHz, and a 48-LQFP package. The STM32F301 family also supports mixed-signal functions including ADC and DAC resources, a CRC calculation unit, reset and power-control capabilities, and DSP-oriented processing. These features make the device suitable for motor-control, industrial automation, sensor acquisition, communications, and compact embedded-control boards.
The M4F core provides 32-bit RISC performance with single-cycle multiplication and hardware division, reducing the instruction overhead often encountered in control and signal-processing loops. The FPU supports floating-point calculations, while DSP instructions improve the implementation of filters, transforms, and digital control algorithms. This combination provides more processing headroom than a basic Cortex-M0-class controller without moving to a larger Cortex-M7-class design.
Typical applications include programmable industrial equipment, motor and motion-control systems, building and access controls, instrumentation, communications modules, and compact consumer appliances. A 48-LQFP package also provides a practical transition path for prototypes and moderately populated production boards because it offers exposed peripheral routing and easier inspection than very-small leadless packages.
Designers should verify the exact peripheral assignments, alternate-function mappings, clock configuration, and analog limits against the STMicroelectronics datasheet before PCB release. The 64 KB Flash and 16 KB SRAM budgets require attention to bootloader size, firmware growth, buffering, and debug support. Power sequencing, decoupling, exposed-pad layout, and clock stability should be evaluated for the final system rather than copied from a generic STM32 layout.
This product page combines verified manufacturer and distributor information with practical selection criteria, procurement context, and design guidance. It distinguishes published STM32F301C8T6 facts from unverified parameters and avoids presenting cross-reference candidates as drop-in replacements unless their package, pinout, memory, and peripheral behavior are demonstrably compatible.

主な用途
STM32F301C8T6 の用途: 6 件s: Industrial Automation Control, Motor and Motion Control, Sensor Acquisition and Instrumentation, Building Access and Security Control, Communication Equipment, Compact Embedded Control Board.
Industrial Automation Control
The STM32F301C8T6 fits compact industrial controllers that coordinate sensors, digital I/O, communications, and real-time control tasks. Its Arm Cortex-M4 core operates up to 72 MHz and includes FPU and DSP instructions, allowing filtering and control calculations to execute without an external processor. The 64 KB Flash and 16 KB SRAM provide space for application firmware, configuration, and working buffers, while the 48-LQFP package simplifies inspection and routing. During implementation, verify the required timer channels, communication peripherals, and isolated I/O interfaces against the exact datasheet.
おすすめ
Motor and Motion Control
The STM32F301C8T6 is appropriate for motor-control and motion-control subsystems that combine PWM generation, current or position feedback, and deterministic embedded logic. The 72 MHz Cortex-M4 core with hardware multiplication, division, FPU, and DSP instructions can accelerate proportional-integral-derivative loops and signal calculations. Its 48-LQFP footprint offers a manageable transition from prototype to production for compact controllers. The design must still confirm timer channel mapping, analog input limits, complementary-output availability, and brake behavior for the selected motor driver before relying on the MCU for safety-critical functions.
おすすめ
Sensor Acquisition and Instrumentation
The STM32F301C8T6 supports measurement instruments that acquire analog sensor data, apply filtering or calibration, and transmit processed results. Its mixed-signal STM32F301 family includes ADC and DAC resources, while the Cortex-M4 FPU and DSP instructions improve handling of sampled data and control equations. With 64 KB of Flash and 16 KB of SRAM, the device can host moderate signal-processing routines while retaining a bootloader and communication stack. Input conditioning, reference accuracy, sampling time, and calibration memory must be evaluated separately from the MCU’s general-purpose processing capability.
おすすめ
Building Access and Security Control
The STM32F301C8T6 can serve as the central controller for building access, alarm, or equipment-security modules that combine user interfaces, sensors, lock outputs, and network communication. The 72 MHz Cortex-M4 core provides responsive control and cryptographic or protocol workload headroom, while 64 KB of Flash and 16 KB of SRAM fit moderate firmware requirements. Its 48-LQFP package supports compact but inspectable boards. Designers should define fail-safe states for locks and alarms, secure programming practices, watchdog use, and safe behavior during brownout or firmware-update events.
おすすめ
Communication Equipment
The STM32F301C8T6 is useful in communication equipment where a local control processor must manage signaling, configuration, diagnostics, and protocol timing. Its 72 MHz Cortex-M4 core and DSP instruction support help process framed data and real-time events, while the 64 KB Flash and 16 KB SRAM can support moderate protocol stacks and buffers. The STM32F301 family’s mixed-signal resources also permit local monitoring. Exact UART, USB, CAN, or other interface availability must be checked by package and pin assignment, and clock tolerance requirements should be met by the selected transceiver and reference components.
おすすめ
Compact Embedded Control Board
The STM32F301C8T6 is a practical controller for compact embedded boards that need more computation than a basic 8-bit device without adopting a large high-pin-count package. Its Cortex-M4 FPU core runs up to 72 MHz, and the 48-LQFP 7 x 7 mm package provides a balanced combination of I/O access, routing simplicity, and manageable production handling. Sixteen kilobytes of SRAM and 64 KB of Flash suit moderate control, logging, and communication tasks. Final board planning should reserve bootloader space, provide stable clocking and decoupling, and verify all pin-level alternate functions against the official package drawing.

設計ノート
Plan the 2.5 V or 3.3 V power architecture from the operating conditions in the STM32F301x6/STM32F301x8 datasheet, including valid voltage ranges for each power mode. Place the required input and internal-regulator bypass capacitors close to their associated pins, and keep sensitive analog and digital return paths within the manufacturer’s layout guidance. Because the exact capacitor values, allowable tolerances, and power-mode constraints are not present in the supplied excerpts, use the official datasheet and reference layout rather than values inferred from generic STM32 designs.
Use the exact 48-LQFP land pattern from the STMicroelectronics package drawing and preserve the pin-1 orientation convention across schematic, CAD footprint, assembly drawing, and board markings. The exposed thermal or electrical pad, if required for the exact package variant, must follow the manufacturer’s copper and solder-mask guidance. Review every alternate-function assignment against the pinout and package table; an LQFP footprint alone does not establish that a candidate device has the same peripheral mapping or pin compatibility.
Do not treat a same-package STM32 or third-party Cortex-M microcontroller as a drop-in replacement merely because both use 48 leads. Bootloader compatibility, GPIO mapping, timer channels, ADC characteristics, interrupts, clock controls, and peripheral behavior can differ substantially. The supplied cross-reference results primarily concern STM32F103 devices and do not prove compatibility with STM32F301C8T6. Validate any proposed replacement through pin-by-pin comparison, schematic review, firmware porting, timing tests, and peripheral-level validation before production use.
Budget the 64 KB Flash and 16 KB SRAM before committing to the application. A bootloader, communication stack, diagnostics, calibration data, and future firmware revisions can consume the nominal memory quickly. Monitor compiler-section placement and stack usage, and avoid placing critical buffers or interrupt context in memory regions that might later be reserved for an update mechanism. The verified excerpts do not provide exact bootloader sizes or peripheral RAM allocation, so those details must be obtained from the linked family documentation.
コンプライアンス情報
The supplied excerpts do not state the target part's compliance or qualification status. These fields remain unknown rather than being inferred from the manufacturer or family name.
