STM32F302RBT6 - 72MHz Cortex-M4 128KB MCU | STMicroelectronics
N.º da peça: STM32F302RBT6 ✓ AtivoSTM32F302RBT6 Visão geral
An ARM Cortex-M4 microcontroller is a 32-bit embedded processor implemented under the Arm Cortex-M architecture. It combines deterministic interrupt-driven execution with DSP instructions for filtering and signal analysis and a single-precision floating-point unit for control calculations. Within the broader hierarchy, the STM32F302RBT6 belongs to the STM32 mixed-signal MCU family and combines a general-purpose microcontroller core with analog peripherals for real-world sensing and control.
The verified manufacturer information identifies a maximum CPU frequency of 72 MHz, 128 Kbytes of Flash, an Arm Cortex-M4 core, DSP and FPU support, a memory protection unit, and CCM. A 12-bit ADC capable of 5 MSPS supports rapid analog acquisition, while the integrated PGA and comparators reduce the need for external signal-conditioning components. These resources make the MCU useful where high-speed sampling, numerical control, and embedded communications must coexist in a compact 64-pin package.
The Harvard-style STM32F3 architecture supports parallel program-memory and data-memory access. The Cortex-M4 processor's DSP and floating-point capabilities accelerate control-loop mathematics, filtering, transformations, and sensor conditioning in software. The dedicated CCM provides an additional tightly coupled memory resource, while the MPU can enforce memory-region protection for more structured embedded designs. Exact RAM capacity, voltage limits, and peripheral operating details are not supplied in the verified source data and therefore require confirmation from the manufacturer documentation.
Typical applications include industrial motor controllers, programmable logic and test equipment, sensor-processing systems, communications equipment, and compact embedded control platforms. The 12-bit 5 MSPS ADC is especially relevant to current sensing, position sensing, vibration monitoring, and process-control loops. The FPU supports real-time filtering and control calculations, while the 128 KB Flash capacity accommodates bootloader, application firmware, and configuration data.
Designers should confirm the complete pin allocation, peripheral remapping, clock limits, analog input range, and electrical operating conditions before layout release. Because the verified excerpts do not provide a complete manufacturer pin table, a published pinout was not reconstructed here. PCB planning should also preserve analog grounding, supply decoupling, and clean routing around the ADC and comparator inputs.
This page combines manufacturer specifications, distributor availability, package information, application guidance, and same-family replacement candidates to support faster component selection and PCB planning. It also distinguishes verified facts from parameters that still require confirmation from the official STM32F302RB documentation.

Aplicações típicas
STM32F302RBT6 é adequado para 6 aplicaçãos: Industrial Motor Control, Industrial Sensor Acquisition, Programmable Logic and Test Equipment, Communications Equipment, Power and Energy Monitoring, Embedded Control and Automation.
Industrial Motor Control
The STM32F302RBT6 fits compact motor-control systems because its 72 MHz Arm Cortex-M4 core combines DSP and FPU instructions with a 12-bit ADC capable of 5 MSPS. Fast current and position sampling can be processed while the floating-point unit executes control-loop calculations. The integrated PGA and comparators can support input conditioning and threshold functions, reducing external circuitry. The 64-LQFP package provides access to a broad pin count without using a large fine-pitch package. Before schematic release, verify the required timer channels, encoder interfaces, analog inputs, complementary outputs, and protection functions in the exact device documentation.
Recomendado
Industrial Sensor Acquisition
The STM32F302RBT6 is suitable for high-speed industrial sensing because its 12-bit ADC operates at up to 5 MSPS and is integrated with a programmable gain amplifier and comparators. Engineers can acquire sensor data, perform scaling and filtering with the Cortex-M4 DSP instructions, and use the FPU for real-time numeric processing. The 128 KB Flash provides room for firmware, calibration tables, and signal-processing routines. Analog layout remains critical: keep sensor traces short, isolate them from switching nodes, and confirm the supported analog input range and acquisition timing from the manufacturer documentation before applying the specified gain.
Recomendado
Programmable Logic and Test Equipment
The STM32F302RBT6 can serve as the control processor in programmable test and measurement equipment where deterministic sampling and numeric processing are required. Its 72 MHz Cortex-M4 core supports responsive command handling, while the 12-bit 5 MSPS ADC provides a fast conversion path for analog test nodes. DSP and FPU instructions can accelerate filtering, calibration, and mathematical correction without offloading those tasks to an external processor. The 64-LQFP footprint also exposes more I/O than smaller packages, although the complete pinout, DAC availability, communication peripherals, and operating limits must be checked before selecting it for a specific instrument architecture.
Recomendado
Communications Equipment
The STM32F302RBT6 fits communications equipment that requires a 72 MHz real-time processor, moderate embedded Flash, and mixed-signal monitoring. Its Cortex-M4 FPU can accelerate protocol, filtering, and data-processing work, while the 12-bit 5 MSPS ADC can monitor line levels, supply conditions, or physical-layer signals. The 64-LQFP package provides a useful balance between pin access and board area. Communication peripherals, supported baud rates, USB or CAN availability, and the exact multiplexed pin assignments must be verified for the selected variant because the supplied verified excerpts summarize the core and analog resources without enumerating every peripheral.
Recomendado
Power and Energy Monitoring
The STM32F302RBT6 is appropriate for embedded power-monitoring controllers because its 12-bit 5 MSPS ADC can sample voltage and current signals rapidly, while the 72 MHz Cortex-M4 performs calibration and real-time computation. DSP instructions support filtering and spectral analysis, and the integrated comparators can support threshold-based events. The device can therefore consolidate measurement, control, and communications tasks in one 64-LQFP package. For accurate energy metering, designers still need suitable sensing hardware, calibration, isolation where required, and careful separation of analog and digital paths. Input voltage limits and shunt-amplifier requirements should be confirmed before circuit implementation.
Recomendado
Embedded Control and Automation
The STM32F302RBT6 works well as a compact embedded controller for automation equipment requiring deterministic timing, digital I/O, and analog monitoring. Its 72 MHz Cortex-M4 core with DSP and FPU can execute control algorithms, while 128 KB Flash accommodates application firmware and configuration data. The mixed-signal peripherals reduce the need to add a separate ADC, PGA, or comparator in straightforward designs. The 64-LQFP package is useful when a design needs more I/O than a compact MCU can provide. Exact GPIO count, communication ports, timer features, and supply constraints must be reviewed against the manufacturer documentation, and firmware should be retested even for close same-family alternatives.

Notas de projeto
Separate analog and digital return paths carefully because the STM32F302RBT6 combines a 12-bit 5 MSPS ADC, PGA, and comparators with a 72 MHz Cortex-M4 core. Place analog input components near the relevant pins, keep sensor traces short, and avoid routing them beneath digital clock or switching-net activity. Confirm the exact analog pins and reference requirements from the complete package drawing because the supplied excerpts do not provide a verified individual pin map.
Do not select the operating voltage, regulator, decoupling network, or analog reference source until the exact STM32F302RBT6 electrical characteristics have been checked. Place the required input, output, and analog bypass capacitors at their specified package pins with short ground paths. A single-zone ground plane may be preferable to split planes; the objective is a low-impedance return under digital switching while maintaining quiet analog routing.
Do not treat same-package STM32F3 candidates as automatic replacements. Compare the complete pin table, alternate-function mappings, timer channels, communication interfaces, ADC channels, clock pins, reset behavior, and firmware startup code. A valid PCB fit must still meet application requirements such as 5 MSPS acquisition, 72 MHz processing, 128 KB Flash, and the required industrial temperature range.
For high-speed control or acquisition designs, review oscillator, debug, and communication routing in the official reference material. Keep clocks away from analog inputs, use short return paths beneath high-speed nets, and add filtering only where supported by the analog front end. The 5 MSPS ADC capability should be validated with the actual source impedance, acquisition time, signal amplitude, and board layout rather than inferred from the headline conversion rate.
Informações de conformidade
RoHS compliance and MSL 3 are stated in the verified component data. The supplied excerpts do not explicitly verify REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status.
