STM32F302RDT6 - 72MHz Cortex-M4 MCU | STMicroelectronics
N.º da peça: STM32F302RDT6 ✓ AtivoSTM32F302RDT6 Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and interface circuitry on one package. The STM32F3 family sits within the broader ARM Cortex-M microcontroller hierarchy and is commonly used for real-time control, embedded signal processing, industrial equipment, communications, and sensor-driven systems. Its Cortex-M4 architecture provides deterministic instruction execution while supporting floating-point operations.
The STM32F302RDT6 operates at a maximum clock frequency of 72 MHz and includes 384 KB of Flash memory. The device also provides 12-bit ADC and DAC functionality, as identified in the product listing. These resources make it suitable for systems that combine control-loop execution with analog measurement or signal generation. The 64-LQFP package exposes a broad set of general-purpose and peripheral pins in a familiar surface-mount footprint.
The STM32F302xD/E family uses an ARM Cortex-M4 32-bit RISC core with an FPU. This architecture is useful for filtering, control calculations, and other numeric operations because the floating-point unit reduces the software and execution burden associated with floating-point arithmetic. The exact RAM capacity, peripheral inventory, supply-voltage limits, and electrical timing values should be confirmed against the manufacturer documentation before final schematic capture.
Typical applications include industrial motor and power conversion controllers, instrumentation front ends, communication modules, data acquisition units, and compact embedded control boards. In these systems, the Cortex-M4 core can execute real-time control algorithms while the 12-bit conversion resources support sensor conditioning and process monitoring. A communication interface can connect the controller to a plant network or service port.
The most important design step is to assign every pin and peripheral against the manufacturer pin-description and package drawings before PCB layout. Confirm clock, reset, boot, power, and decoupling requirements directly from the STMicroelectronics STM32F302 documentation. This prevents assumptions about multiplexed functions, alternate operating modes, or exposed pad requirements from entering the board design.
This product page combines the verified 72 MHz Cortex-M4, 384 KB Flash, 12-bit conversion, and 64-LQFP characteristics with practical application guidance, sourcing information, and component-selection context. It is designed to help engineers identify the correct MCU and verify the mechanical and electrical details needed for a robust embedded design.

Aplicações típicas
STM32F302RDT6 é adequado para 6 aplicaçãos: Industrial Motor Control, Data Acquisition and Instrumentation, Communication Gateway, Power Conversion Controller, Sensor Hub and IoT Controller, Audio and Signal Control.
Industrial Motor Control
The STM32F302RDT6 fits real-time motor-control systems because its 72 MHz ARM Cortex-M4 core provides deterministic control-loop execution while the FPU supports numeric calculations. The 12-bit ADC can acquire current, position, or analog sensor feedback for proportional, integral, and derivative control functions. Its 64-LQFP package provides a broad interface surface for PWM-capable timers, encoders, control signals, communications, and debug access. Validate timer-channel mapping, analog input limits, and pin multiplexing against the manufacturer documentation before assigning signals.
Recomendado
Data Acquisition and Instrumentation
The STM32F302RDT6 is appropriate for compact instrumentation and data-acquisition equipment that must sample analog signals and execute control or signal-processing firmware. Its 12-bit ADC supports direct measurement of process variables, while the 72 MHz Cortex-M4 core can perform filtering, calibration, scaling, and communication tasks. The 64-LQFP package makes numerous sensor, reference, interface, and serial-communication connections accessible. Confirm the number of ADC channels, acquisition time, input range, and reference requirements before finalizing the analog front end.
Recomendado
Communication Gateway
The STM32F302RDT6 can serve as the embedded controller in a communication gateway where protocol processing, status monitoring, and local control must coexist on one board. Its 72 MHz Cortex-M4 core provides ample headroom for interrupt-driven serial handling and protocol conversion, while 384 KB of Flash stores application firmware and configuration data. The 64-LQFP package supports multiple serial, debug, and control connections. Choose external interface transceivers according to the required physical layer, isolation, voltage, and cabling environment.
Recomendado
Power Conversion Controller
The STM32F302RDT6 is suited to supervisory and digital control roles in power-conversion equipment because it combines a 72 MHz Cortex-M4 processor, 12-bit ADC capability, and a pin-rich 64-LQFP package. Firmware can supervise analog feedback, manage operating states, and coordinate external switching components through timer-driven control signals. The FPU supports numeric control calculations, although loop timing must be validated against peripheral capabilities. Confirm comparator, timer, PWM, and protection functions in the manufacturer documentation before assigning safety-critical controls.
Recomendado
Sensor Hub and IoT Controller
The STM32F302RDT6 works well as a local sensor-hub processor when several measurements must be acquired, conditioned, and forwarded through a serial or network link. Its 12-bit ADC supports sensor monitoring, and the 384 KB of Flash provides room for firmware, calibration tables, and communication stacks. The 64-LQFP package offers enough connections for digital sensors, indicators, status lines, and debug. Review peripheral mapping and unused-pin termination in the manufacturer pin table to prevent assignment conflicts.
Recomendado
Audio and Signal Control
The STM32F302RDT6 can support audio or general signal-control systems where real-time sampling and numeric processing are required. Its 12-bit DAC provides a digital-to-analog conversion resource, while the 12-bit ADC supports feedback measurement, and the Cortex-M4 FPU accelerates filtering and control mathematics. The 64-LQFP package provides access to multiple peripheral and general-purpose signals. Audio performance still depends on the analog design, clocking scheme, reference voltage, output filtering, and selected peripheral routing, all of which require application-level verification.

Notas de projeto
Assign the 64-LQFP footprint directly from the STM32F302RDT6 package drawing and pin-description table. Verify every power, ground, reset, boot, clock, debug, analog, and peripheral signal before symbol release. Place required decoupling capacitors close to their associated supply pins, provide a clean ground return, and route high-current or switching-node connections away from ADC and oscillator inputs.
Plan the 2.5 V or 3.3 V supply for the MCU, analog circuitry, external peripherals, and expected transient loads rather than the nominal MCU current alone. Include regulator startup, inrush, voltage tolerance, and local bypass requirements in the power budget. Confirm the exact internal-regulator configuration and decoupling sequence in the manufacturer electrical-characteristics and application guidance.
Keep the 72 MHz clock path short, continuous, and away from switching-node and high-current return paths. Use the manufacturer-referenced oscillator or internal-clock configuration, and place associated load and bypass components according to the recommended layout. For analog measurements, reserve a clean return path, control trace leakage, and separate noisy digital return current from sensitive input routing.
Do not treat every STM32F3 order code as an interchangeable substitute. The RD designation identifies the 64-LQFP package and 384 KB Flash configuration, while pin multiplexing and peripheral availability must be checked for the exact suffix. Before programming, confirm the startup option bytes, debug interface, clock tree, and peripheral pin assignments against the manufacturer documentation.
