STM32F303C8T6 - 72MHz Cortex-M4 MCU with 64KB Flash | STMicroelectronics
N.º de pieza: STM32F303C8T6 ✓ ActivoSTM32F303C8T6 Descripción general
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripheral interfaces on one integrated circuit. The STM32F303C8T6 belongs to the STM32F3 family of 32-bit microcontrollers and provides an Arm Cortex-M4 RISC core with hardware floating-point capability. This hierarchy places the device within embedded processors, microcontrollers, and industrial semiconductor control systems.
Principal features include a 72 MHz Cortex-M4 core, 64 KB Flash, 16 KB SRAM, two analog-to-digital converters, and three digital-to-analog converters. Its CAN interface supports standard and extended data frames at bit rates up to 1 Mbit/s according to the manufacturer datasheet. The 48-pin LQFP package also provides access to mixed-signal, timer, communication, and general-purpose input/output resources.
The Cortex-M4 architecture supports efficient digital signal processing while retaining a broad embedded-control feature set. Hardware floating-point instructions accelerate suitable math operations without requiring a separate DSP. Separate ADC and DAC resources can support measurement and controlled-output systems, while CAN provides a robust option for communication with industrial equipment, sensors, or distributed control nodes.
Typical applications include motor and power-system controllers, industrial sensor nodes, CAN-connected machinery, data-acquisition systems, compact instrumentation, and embedded control platforms. The 72 MHz core provides useful timing headroom for concurrent peripheral operation, and the mixed-signal resources reduce the need for external converters in designs that require controlled analog input or output signals.
Designers should verify power-supply requirements, decoupling, clock configuration, boot pins, and all 48 package assignments against the official STM32F303C6 datasheet before layout release. Because the supplied verification data confirms the family-level electrical capabilities but does not expose the complete package pin map, the pinout field is intentionally left null rather than reconstructing assignments from memory. Firmware migration should also be checked for peripheral, clock, and startup-support differences.
This page consolidates verified manufacturer and distributor information, package details, procurement guidance, comparison fields, and practical engineering cautions. It distinguishes documented facts from unresolved data so engineers can evaluate the STM32F303C8T6 efficiently without mistaking generic cross-reference listings for verified drop-in replacements.

Aplicaciones típicas
STM32F303C8T6 es adecuado para 6 aplicacións: CAN-Connected Industrial Control, Motor and Power-System Monitoring, Data Acquisition and Instrumentation, CAN-Based Sensor Node, Embedded Automation and Robotics, Digital Audio and Signal Control.
CAN-Connected Industrial Control
The STM32F303C8T6 fits CAN-connected industrial controllers because its Cortex-M4 core runs at up to 72 MHz and its CAN interface supports standard and extended frames at up to 1 Mbit/s. The 64 KB Flash and 16 KB SRAM provide space for control code, protocol handling, and operating parameters. Two ADCs and three DACs can support sensor acquisition and actuator control without requiring separate converters. Engineers should preserve the manufacturer's recommended decoupling and provide the transceiver, termination, protection, and common-mode solution required by the target CAN network.
Recomendado
Motor and Power-System Monitoring
The STM32F303C8T6 is suitable for motor-control monitoring and compact power-system controllers where fast control logic and mixed-signal measurement are valuable. Its 72 MHz Arm Cortex-M4 core provides computational headroom, while the hardware floating-point unit supports math-heavy control calculations. Two ADCs can monitor voltage or current-related signals, and the three DACs can provide controlled outputs for test or low-level drive functions. The exact PWM, timer, and analog input assignments must be checked against the official pin table before connecting power-stage hardware.
Recomendado
Data Acquisition and Instrumentation
The STM32F303C8T6 supports compact data-acquisition and instrumentation designs that combine sensor conditioning, digital processing, and communications. Its 72 MHz Cortex-M4 core can process sampled data while the two integrated ADCs provide analog measurement channels. The three DACs can generate calibration or control signals, and the 64 KB Flash accommodates firmware without requiring the largest memory configuration. Designers should verify ADC accuracy requirements, input impedance, sampling time, reference voltage, and calibration strategy against the full manufacturer electrical tables.
Recomendado
CAN-Based Sensor Node
The STM32F303C8T6 works well as the controller in a distributed sensor node that must acquire local analog measurements and report them over a CAN network. Its two ADCs support sensor interfacing, while the 72 MHz processor provides timing margin for filtering, diagnostics, and protocol processing. CAN operation at up to 1 Mbit/s enables compact communication links between industrial nodes. A suitable transceiver such as SN65HVD06D is still required, along with bus termination, surge protection, isolation where needed, and firmware checks for arbitration and fault handling.
Recomendado
Embedded Automation and Robotics
The STM32F303C8T6 is appropriate for embedded automation modules that combine deterministic control, analog sensing, and network communications. Its Cortex-M4 floating-point core supports signal-processing and control tasks, while the 48-LQFP package offers a conventional surface-mount format for industrial controller boards. Two ADCs and three DACs reduce external mixed-signal component counts, and CAN provides a reliable link to actuators and supervisory controllers. Validate environmental temperature, isolation strategy, grounding, EMC behavior, and functional safety requirements for the final robotic or factory system.
Recomendado
Digital Audio and Signal Control
The STM32F303C8T6 can serve in compact digital audio and signal-control equipment where the Cortex-M4 DSP instructions and hardware floating-point unit improve calculation throughput. Its 72 MHz clock supports real-time processing, while two ADCs and three DACs provide the principal conversion paths for audio-oriented control and monitoring designs. The device does not include a dedicated high-fidelity audio interface, so signal conditioning, clocking, and output filtering remain important. Engineers should verify the required audio bandwidth, converter performance, aliasing control, and total harmonic distortion in the manufacturer data.

Notas de diseño
Use the power-supply and decoupling requirements stated in the official STM32F303C6 datasheet. Place local bulk and high-frequency bypass capacitors close to the appropriate supply and ground pins, keep return currents compact, and verify startup behavior with the selected operating voltage. The supplied excerpts confirm 2.5 V and 3.3 V operation but do not provide regulator tolerances or capacitor values, so those values must be taken from the manufacturer table rather than estimated.
Finalize the board using the official 48-LQFP pin-definition table and package drawing. Route analog inputs away from switching nodes and high-current return paths, provide a quiet ground reference for the ADCs and DACs, and check external component placement against each associated pin. Because the complete pin map was not included in the supplied excerpts, the structured pinout is intentionally null; reproducing pin numbers from memory could create assembly or rework errors.
Do not treat a generic STM32 cross-reference as proof of drop-in compatibility. The supplied replacement guides note that GD32F103 is associated with STM32F103 rather than STM32F303, while other pin-compatible devices can still differ in firmware, clocks, peripherals, and electrical timing. For any proposed substitute, verify the package drawing, power pins, boot behavior, oscillator connections, peripheral mapping, and required toolchain support.
For CAN-connected equipment, separate the MCU's digital return current from the transceiver and protected bus currents as far as the layout permits. Use the transceiver manufacturer's recommended isolation, termination, common-mode, and surge-protection arrangements. The STM32F303C8T6's 1 Mbit/s CAN capability is a communications specification, not evidence that the assembled system will pass EMC testing without enclosure, grounding, filtering, and cable-design validation.
Información de cumplimiento
The supplied verified excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from general STM32 family practices.
