Артикул: STM32F302CCT6 ✓ АктивенSTM32F302CCT6 Обзор
A microcontroller is a programmable system-on-chip that integrates a CPU core, memory, peripherals, and interface controllers into one package. The STM32F302 belongs to the STM32F3 mixed-signal family, combining general-purpose embedded control with fast analog-to-digital conversion. This makes it more capable than a basic microcontroller while retaining a familiar Arm Cortex-M software ecosystem and peripheral architecture.
Key features include a 72 MHz Cortex-M4 processor, 256 KB of Flash memory, an FPU and DSP support, a 12-bit ADC capable of 5 MSPS according to the manufacturer product page, programmable gain amplification, comparators, and an MPU. The mixed-signal resources allow the device to sample and process sensor signals while controlling timers, communications, and actuators without requiring a separate high-speed analog device.
The STM32F302CCT6 is identified as an active mainstream product by STMicroelectronics. Its 48-LQFP package provides enough pins for mixed signal, motor-control, and general embedded connectivity while remaining compatible with conventional leaded assembly and inspection processes. The Cortex-M4 architecture supports efficient interrupt handling, deterministic real-time control, and floating-point or DSP calculations.
Typical applications include industrial sensor nodes, motor and power-control systems, building automation, instrumentation, communications equipment, and compact embedded control platforms. Designers should verify the complete pin configuration, peripheral availability, operating-temperature grade, electrical limits, and package details against the manufacturer datasheet before releasing a production design.
A key design consideration is preserving analog performance. The ADC and PGA resources should be used with appropriate input conditioning, reference-voltage stability, grounding, and layout separation from switching nodes. Firmware should also account for startup, calibration, and the timing relationship between the 72 MHz CPU and the available peripherals.
This product page combines the verified manufacturer and distributor information with application guidance, selection trade-offs, and practical considerations that are not normally consolidated in a distributor catalog. It is intended to help engineers confirm package, memory, performance, sourcing, and replacement requirements before selecting the STM32F302CCT6.

Типичное применение
STM32F302CCT6 подходит для 6 применениеs: Industrial Sensor Acquisition, Motor Control and Power Conversion, Building Automation and HVAC Control, Communications Gateway and Protocol Node, Precision Instrumentation, Condition Monitoring and Diagnostics.
Industrial Sensor Acquisition
The STM32F302CCT6 fits industrial sensor nodes that need fast mixed-signal measurement and real-time control. Its 12-bit ADC operates at up to 5 MSPS, while the 72 MHz Cortex-M4 core, DSP support, and FPU can perform filtering and control calculations close to the sensor. The device can also use its PGA and comparator resources to condition signals and establish thresholds. In this role, engineers can connect analog sensors to the mixed-signal inputs, run acquisition in the firmware, and publish processed measurements over an available communication peripheral. The 256 KB Flash configuration provides room for application code, and the 48-LQFP package keeps the assembly compact. Verify the selected ADC channels, trigger behavior, reference accuracy, and analog operating limits in the manufacturer datasheet.
Рекомендуется
Motor Control and Power Conversion
The STM32F302CCT6 is suitable for compact motor-control and power-conversion control loops because its 72 MHz Cortex-M4 core combines deterministic control processing with DSP and FPU capabilities. Fast 12-bit conversion at up to 5 MSPS can support current or position feedback when the selected pins, trigger source, and acquisition sequence meet the timing requirements. Comparators and the PGA can assist in protection or signal conditioning, while the MCU executes control algorithms and manages gate-drive sequencing. The 48-LQFP 7x7 mm package provides a practical pin count for a three-phase or auxiliary control design. Actual replacement suitability depends on timer channels, PWM outputs, analog inputs, and fault-handling resources, which must be checked against the exact STM32F302CCT6 datasheet.
Рекомендуется
Building Automation and HVAC Control
The STM32F302CCT6 can serve as the local controller in building automation, HVAC, and environmental monitoring equipment. Its 72 MHz Arm Cortex-M4 core provides enough performance for sensor fusion, control loops, communications, and supervisory logic, while the 12-bit 5 MSPS ADC handles mixed analog inputs such as temperature, pressure, or flow signals. The PGA and comparators can simplify front-end design when the application needs gain adjustment or threshold detection. Because the MCU provides 256 KB of Flash, typical field firmware can include control algorithms, diagnostics, and communication stacks. Use the low-power modes and peripheral clocking only after checking wake-up requirements and retention behavior in the datasheet. The 48-LQFP package is also suitable for leaded industrial assembly.
Рекомендуется
Communications Gateway and Protocol Node
The STM32F302CCT6 is appropriate for compact protocol-conversion and communications nodes that require real-time response without a separate DSP. Its 72 MHz Cortex-M4 core supports interrupt-driven serial handling, protocol parsing, and DSP-assisted filtering, while the 256 KB Flash capacity supports moderate networking and application firmware. The mixed-signal ADC can supervise supply voltage or interface analog telemetry without occupying a separate MCU. The 48-LQFP package provides a practical balance between pin availability, inspection, and board area. Firmware designers should confirm that the required USART, SPI, I2C, USB, or CAN resources are present and mapped to the desired pins. EMC, isolation, grounding, and connector protection are board-level concerns that remain necessary even when the MCU itself is well specified.
Рекомендуется
Precision Instrumentation
The STM32F302CCT6 fits precision instrumentation that combines analog measurement with digital correction and a human-machine or communications interface. The 12-bit ADC can sample up to 5 MSPS according to the manufacturer, while the Cortex-M4 FPU and DSP instructions assist with scaling, filtering, and calibration. The PGA may reduce the dynamic range required from the front end, and comparators can provide fast threshold events. With 256 KB of Flash, the controller can combine acquisition routines, calibration tables, diagnostics, and protocol handling in one device. Accuracy still depends on the voltage reference, analog topology, grounding, sample settling, and digital filtering. Engineers should use the manufacturer's recommended application information and verify acquisition timing before using the maximum conversion rate in a precision measurement chain.
Рекомендуется
Condition Monitoring and Diagnostics
The STM32F302CCT6 can act as a local condition-monitoring controller for motors, pumps, actuators, or industrial machinery. Fast 12-bit conversion supports acquisition of vibration, current, or transducer signals, while the Cortex-M4 DSP and FPU features can support filtering and envelope analysis. The PGA and comparator resources may reduce front-end complexity for selected diagnostic signals. Firmware can use timers for regular sampling, perform threshold evaluation, and report results through a serial or industrial network interface. The 48-LQFP package makes the controller practical for compact multi-board equipment. For field reliability, designers should verify watchdog coverage, error recovery, temperature limits, and any safety requirements against the official documentation; the verified excerpts do not provide those electrical details.

Заметки по проектированию
Route analog inputs away from switching-node traces and digital return currents. The verified device provides a 12-bit ADC operating up to 5 MSPS, so high-impedance sensor nodes can be sensitive to leakage, ground coupling, and trace capacitance. Keep the analog ground and digital ground strategy consistent with the manufacturer's recommended application layout, use a quiet reference source, and place input protection components close to the connector where cable transients are possible.
The verified excerpts do not provide the STM32F302CCT6 supply-voltage range, decoupling requirements, or current limits. These values must be copied directly from the manufacturer datasheet before selecting capacitors, regulators, or power-sequencing components. In particular, verify operating conditions for the 72 MHz core, ADC accuracy, Flash operation, and analog peripherals; the presence of a 256 KB Flash memory should not be used to infer a valid operating voltage.
Do not treat every listed alternative as a source-identical substitute. The verified cross-reference material lists several STM32 devices, but it does not establish equal Flash, RAM, ADC, timer, communications, and qualification specifications. Before replacing the target, compare the exact order code, memory map, peripheral map, package drawing, pin multiplexing, electrical limits, and boot configuration. Also verify that firmware does not depend on a debug identifier or peripheral that differs between families.
The STM32F302CCT6 is supplied in a 48-LQFP 7x7 mm package, so the PCB land pattern should come from the official package drawing rather than a generic LQFP footprint. Confirm lead pitch, exposed versus non-exposed pad details, pin-one orientation, solderable land geometry, and assembly tolerances. A 0.5 mm-pitch LQFP also warrants careful stencil and solder-process design to avoid bridging between closely spaced leads.
