부품 번호: STM32F302C6T6 ✓ 활성STM32F302C6T6 개요
A microcontroller is a programmable semiconductor that integrates a processor core, memory, timers, serial interfaces, analog conversion functions, and GPIO into one package. The STM32F302 belongs to the STM32F3 mixed-signal MCU family and sits within the hierarchy of Arm Cortex-M microcontrollers, embedded processors, and general-purpose semiconductor devices. Its integrated floating-point unit accelerates arithmetic operations commonly used in control algorithms and digital signal processing.
The STM32F302C6T6 provides 32 KB of flash for firmware and 16 KB of SRAM for working data, while its Cortex-M4 core supports operation up to 72 MHz. A 12-bit ADC is identified in the verified distributor data, supporting mixed-signal applications where measured analog inputs must be processed locally. The 48-pin LQFP package also provides more I/O and peripheral connectivity than smaller 32-pin alternatives.
The STM32F302x6/8 family combines a high-performance 32-bit RISC core with mixed-signal peripherals in STMicroelectronics’ STM32 architecture. The target is identified as a 32 KB flash, 16 KB SRAM device in the verified comparison data, while the family description confirms the Cortex-M4 core, floating-point unit, and maximum 72 MHz operating frequency. Package code C6 denotes the 48-pin configuration used by STM32F302C6T6.
Typical uses include industrial sensor controllers, motor-control systems, compact instrumentation, digital power converters, and communication equipment. The 72 MHz processor provides timing margin for protocol handling and real-time control, while the floating-point unit simplifies implementation of PID loops, filtering, and transform calculations. The mixed-signal orientation is useful when analog measurements, timers, and serial communications must share one controller.
Designers should verify the complete pinout, peripheral configuration, clock tree, and electrical limits against the manufacturer datasheet before layout release. The LQFP footprint is straightforward to assemble and inspect, but decoupling, grounding, analog-input routing, and unused-pin handling still require disciplined PCB implementation. Firmware must also be validated against the relevant STM32F3 reference manual and errata.
This page consolidates the verified manufacturer and distributor information, same-family drop-in candidates, parameter comparisons, application guidance, and practical design cautions. It highlights where the STM32F302C6T6 fits and documents the uncertainties that require datasheet confirmation rather than presenting unsupported assumptions as production facts.

Industrial Sensor Controller
The STM32F302C6T6 fits compact industrial sensor controllers because its 72 MHz Arm Cortex-M4 core can process measurements while the 12-bit ADC handles analog inputs. With 32 KB of flash and 16 KB of SRAM, it can hold application firmware, calibration data, and working buffers without requiring an external memory device. The 48-pin LQFP provides enough connections for sensors, digital interfaces, status indicators, and actuator outputs. Designers should route analog inputs away from switching nodes, provide local decoupling, and confirm the device’s exact pin functions and operating-temperature grade in the manufacturer documentation.
추천
Motor Control and PWM
The STM32F302C6T6 is appropriate for embedded motor-control and PWM systems where deterministic control-loop execution and mixed-signal monitoring are important. Its 72 MHz Cortex-M4 core provides processing margin, while the integrated floating-point unit supports PID calculations and filtering without fixed-point emulation. The 48-pin package can expose timer channels, PWM outputs, feedback inputs, communications, and protection signals. The STM32F334C6T6 may be considered where its highlighted high-resolution timer provides a benefit, but engineers must compare timer channels, pin mapping, dead-time support, and control-library coverage before exchanging the two devices.
추천
Digital Power Converter Control
The STM32F302C6T6 can serve as the supervisory controller in a digital power converter because the 72 MHz Cortex-M4 core can execute control loops while the 12-bit ADC observes voltage and current signals. Its mixed-signal STM32F3 heritage supports compact power-conversion designs that require measurement, timing, and communications in one package. The 32 KB flash capacity is suitable for a focused control application, while 16 KB of SRAM supports working calculations and status buffers. Engineers must verify ADC accuracy, PWM resolution, timer synchronization, protection behavior, and thermal margins against the specific power-stage requirements.
추천
Compact Data Acquisition System
The STM32F302C6T6 is suitable for compact data-acquisition equipment because it combines a 12-bit ADC, 72 MHz processing, and 16 KB of SRAM in a 48-pin LQFP package. Firmware can sample analog channels, filter results, apply calibration, and format data for a host or local display. The Cortex-M4 FPU improves the efficiency of common signal-processing arithmetic. Layout quality is especially important: use a quiet analog ground strategy, minimize analog trace exposure to switching currents, and verify the ADC settling, reference, input-range, and sampling-time requirements in the manufacturer documentation.
추천
Communication Equipment Interface
The STM32F302C6T6 can act as the local control processor in communication equipment requiring real-time protocol handling, status monitoring, and configurable I/O. Its 72 MHz Cortex-M4 core provides more instruction throughput than a basic Cortex-M0-class controller, and the integrated FPU can accelerate signal-processing or control functions. The 48-pin LQFP offers a practical balance between external connections and package size. Firmware and hardware validation should cover peripheral instances, interrupt priorities, oscillator requirements, communication timing, and pin multiplexing before treating it as a replacement for an existing design.
추천
Precision Instrumentation
The STM32F302C6T6 fits precision instrumentation where measurement, timing, and numerical processing must coexist in a compact controller. Its 72 MHz Cortex-M4 core and floating-point unit support real-time filtering, calibration, compensation, and instrument-control algorithms, while the 12-bit ADC provides an analog acquisition path. The 7 x 7 mm, 48-pin LQFP package simplifies assembly compared with very fine-pitch packages. For laboratory or metrology equipment, confirm ADC characteristics, reference stability, clock accuracy, noise performance, and calibration requirements in the official datasheet before committing to the device.

설계 노트
Place all required decoupling capacitors immediately adjacent to the corresponding supply and ground pins, with the shortest possible loop and clean return paths. Keep analog inputs and their reference routing away from PWM outputs, high-current switching nodes, and inductor areas. Use a continuous ground reference beneath the device where practical, but follow the manufacturer package and layout guidance when it specifies a particular grounding or thermal-pad arrangement.
Validate every signal assigned to the 48-pin LQFP against the official STM32F302x6/8 pin table, including analog-capable pins, oscillator pins, debug functions, and alternate functions. Do not infer pin equivalence solely from package count or the similarity of other STM32F3 devices. Check boot configuration, exposed debug access, unused-pin treatment, and any pins that require external components before releasing the PCB.
A same-package migration is not automatically a drop-in replacement. Compare the STM32F302C6T6 against STM32F334C6T6 or other candidates for peripheral availability, timer channels, interrupt mapping, boot behavior, flash organization, clock limits, errata, and toolchain support. The STM32F103C6T6A migration is especially significant because it uses Cortex-M3 without the target’s FPU, so floating-point firmware and timing assumptions must be reviewed.
Design the 2.5 V to 3.3 V supply with low noise and adequate startup behavior because ADC measurements, communications, and control timing depend on stable rails. Confirm the device’s internal regulator, external component, clock, and brownout requirements in the manufacturer documentation. Avoid placing analog-sensitive circuitry close to noisy switching supplies unless the board stack-up and return-current plan isolate those domains effectively.
