STM32F373CBT6 Visão geral

STMicroelectronics STM32F373CBT6 is a 32-bit ARM Cortex-M4 microcontroller operating up to 72 MHz, with 128 KB of Flash memory and a 48-LQFP 7 x 7 mm package. It combines a floating-point-capable processor core with embedded signal-processing and control resources for compact industrial, instrumentation, consumer, and communications designs. The supplied distributor records identify the device as an STM32F3-series microcontroller with an FPU and 128 KB Flash.

A microcontroller is a programmable semiconductor system that integrates a CPU core, memory, peripherals, and interfaces onto one device. The STM32F3 family belongs to the broader embedded-controller hierarchy: ARM Cortex-M core, 32-bit RISC processor, embedded microcontroller, and programmable control component. This classification makes the STM32F373CBT6 suitable where local real-time control and computational processing must coexist on a small PCB footprint.

The principal verified specifications are a 72 MHz maximum operating frequency, 128 KB Flash organized as 128K x 8, a 32-bit ARM Cortex-M4 core, and a 48-LQFP 7 x 7 mm package. The family description also identifies floating-point capability, while distributor results characterize the MCU with an FPU. These resources support motor-control logic, digital signal processing, sensor acquisition, communications, and general embedded control, subject to detailed peripheral and electrical validation from the manufacturer documentation.

The Cortex-M4 architecture provides a 32-bit processing environment with single-precision floating-point support, which is useful for control equations and signal-processing routines that would burden an 8- or 16-bit MCU. The 128 KB Flash region provides on-chip program storage for firmware, while RAM capacity and additional interface details were not present in the supplied authoritative snippets and therefore require confirmation from the manufacturer datasheet before design release.

Typical uses include digital power conversion, motor and motion control, industrial measurement modules, compact sensor controllers, communications equipment, audio or general DSP-assisted signal chains, and consumer products requiring more processing than a basic microcontroller. The 7 x 7 mm LQFP also offers exposed leads for assembly and inspection compared with leadless packages.

Design work should begin with the STMicroelectronics STM32F373CB product page and STM32F373 documentation, then verify electrical limits, complete peripheral assignments, clock requirements, decoupling, programming, and exposed-pad requirements in the manufacturer datasheet. Do not infer unused pins, ADC ratings, timers, or package thermal performance from distributor snippets alone.

This page consolidates verified distributor specifications, official STMicroelectronics resources, sourcing information, and engineering-selection guidance. It deliberately distinguishes confirmed facts from missing datasheet details so engineers can evaluate the STM32F373CBT6 without relying on unverified assumptions.

Aplicações típicas

STM32F373CBT6 é adequado para 6 aplicaçãos: Motor and Motion Control, Digital Signal Processing, Industrial Sensor Conditioning, Communications and Gateway Equipment, Consumer Control Products, Power Conversion and Digital Monitoring.

🏭

Motor and Motion Control

The STM32F373CBT6 fits compact motor-control and motion-control designs that benefit from a 72 MHz ARM Cortex-M4 core and FPU. The processor can execute control equations, state logic, and timing routines while the STM32F3 family provides the broader platform for embedded control peripherals. Its 128 KB Flash provides room for application firmware, and the 48-LQFP 7 x 7 mm package supports accessible assembly. Before selecting the part, verify timer channels, encoder interfaces, PWM outputs, current sensing, voltage limits, and temperature grade in the official datasheet.

📡

Digital Signal Processing

The STM32F373CBT6 is suitable for DSP-assisted instrumentation because its verified ARM Cortex-M4 core operates up to 72 MHz and includes an FPU. Floating-point hardware is valuable when a design uses filtering, transforms, control calculations, or fixed-point conversion software. The 128 KB Flash store can hold firmware and lookup data, but the available RAM and signal-chain peripherals must be confirmed before sizing buffers. Use the manufacturer datasheet and reference manual to verify ADC, timer, DMA, and memory specifications rather than assuming interface availability.

🧩

Industrial Sensor Conditioning

The STM32F373CBT6 can serve as the control processor in a compact sensor-conditioning module where deterministic local computation and embedded control are required. Its 32-bit Cortex-M4 architecture, 72 MHz headline frequency, and FPU support more capable filtering and compensation routines than a basic low-power MCU. The 48-LQFP package provides a practical surface-mount footprint for equipment with moderate board space. Confirm the actual ADC resolution, input count, sampling rate, operating temperature, and communication interfaces before using the device in a safety- or measurement-critical system.

🌐

Communications and Gateway Equipment

The STM32F373CBT6 is applicable to communications equipment that requires local protocol handling, configuration, and control alongside a host processor. Its 72 MHz ARM Cortex-M4 core can support event-driven firmware, while 128 KB Flash provides a defined firmware region for a focused embedded application. The LQFP package is easy to inspect and assemble in moderate-volume industrial or consumer gateway products. Verify UART, USB, CAN, SPI, I2C, Ethernet-related support, pin multiplexing, and electrical constraints in the official documentation because those interfaces are not specified in the supplied search snippets.

📱

Consumer Control Products

The STM32F373CBT6 can be used in consumer devices that need more control capability than a simple state-machine MCU but do not require a large package. The verified 72 MHz Cortex-M4 core and FPU help support user-interface logic, motor sequencing, sound-related control, and configurable product behavior, while 128 KB Flash accommodates embedded firmware. The 48-LQFP package remains practical for conventional PCB assembly. A production design must still verify standby behavior, brownout behavior, supply voltage, peripheral mix, ESD requirements, and lifecycle commitments from STMicroelectronics documentation.

⚡

Power Conversion and Digital Monitoring

The STM32F373CBT6 is a reasonable platform candidate for digital power conversion and monitoring functions when the design benefits from fast 32-bit control and floating-point computation. It can coordinate sequencing, measurement handling, fault logic, and communication tasks around a power subsystem, provided its confirmed timers, ADC, PWM, DMA, and comparison resources satisfy the design. The 128 KB Flash provides space for control and monitoring firmware. Validate input-voltage limits, conversion performance, isolation strategy, thermal conditions, and safety requirements against the official electrical and application documentation.

What are the key specifications of STM32F373CBT6 that engineers should know?
The STM32F373CBT6 is a 32-bit ARM Cortex-M4 microcontroller rated up to 72 MHz, with 128 KB Flash, an FPU, and a 48-LQFP 7 x 7 mm package. According to the STMicroelectronics STM32F373CB product page and the supplied DigiKey record, it belongs to the STM32F3 family and supports floating-point-oriented embedded processing. The verified snippets do not provide the complete RAM, voltage, temperature, GPIO, timer, or ADC specifications, so engineers should confirm those values in the manufacturer documentation before finalizing a design.
What is the operating frequency of STM32F373CBT6?
The STM32F373CBT6 operates at up to 72 MHz according to the supplied DigiKey and Mouser records and the STMicroelectronics family description. Its ARM Cortex-M4 core provides a 32-bit RISC execution environment, while the FPU accelerates floating-point workloads. The maximum frequency is a verified headline specification, but the complete clock-tree, voltage, and peripheral-clock requirements should be taken from the manufacturer datasheet rather than inferred from the distributor summary.
Where can I download the STM32F373CBT6 datasheet PDF?
The official starting point is the STMicroelectronics STM32F373CB product page at https://www.st.com/en/microcontrollers-microprocessors/stm32f373cb.html, with documentation resources linked from https://www.st.com/en/microcontrollers-microprocessors/stm32f373/documentation.html. The supplied search results also identify a Datasheets.com mirror, but STMicroelectronics is the authoritative source for electrical limits, pin assignments, memory, timing, and package drawings.
Where can I find the STM32F373CBT6 pinout?
The pinout should be obtained from the STM32F373CB manufacturer documentation because the supplied web snippets confirm a 48-LQFP 7 x 7 mm package but do not enumerate all pin numbers or names. Do not infer pin assignments from a generic STM32F3 board or from a different STM32F3 package. Confirm the pinout, alternate functions, power pins, ground pins, programming pins, and exposed thermal-pad details against the official device documentation.
How much Flash memory does STM32F373CBT6 have?
The STM32F373CBT6 provides 128 KB of Flash memory, specified in the verified distributor result as 128K x 8. This storage is intended for firmware and application code, subject to the device's boot, option-byte, and programming constraints described by STMicroelectronics. The supplied snippets do not state RAM capacity, so memory sizing must be completed using the manufacturer datasheet before allocating buffers or upgrading an existing STM32 design.
Is STM32F373CBT6 suitable for floating-point and DSP applications?
The STM32F373CBT6 is a strong candidate for floating-point and DSP-assisted control because the verified product records identify an ARM Cortex-M4 core and an FPU. The Cortex-M4 instruction set and floating-point hardware can improve control-loop and signal-processing performance compared with a basic 8-bit or 16-bit controller. Actual throughput, peripheral synchronization, and timing margins still depend on the selected algorithm, clock configuration, memory architecture, and application code.
Is STM32F373CBT6 in stock and where can I buy it online?
The supplied LCSC result explicitly describes STM32F373CBT6 as in stock and lists a price starting at $4.2373. DigiKey, Mouser, Octopart, and LCSC are listed as online sourcing channels, while the snippet does not establish a guaranteed XAIPART stock position. For procurement, compare authorized-distributor inventory, pack quantity, lead time, and landed cost rather than relying on one distributor's search-result availability.
What is the price of STM32F373CBT6 as of 2026-10-23?
The verified LCSC listing gives STM32F373CBT6 pricing from $4.2373, and that price is the only numerical unit price supplied. The available distributor snippets for DigiKey, Mouser, and Octopart request live pricing rather than providing reproducible quote values. Accordingly, the listed tiers retain $4.2373 for all quantities as a conservative data-transcription choice, not as an assertion that every quantity break has the same commercial price. Confirm current pricing with the seller.
What is the lead time for STM32F373CBT6?
The supplied data does not provide a verified lead-time value for STM32F373CBT6, so a numerical lead time cannot be stated responsibly. LCSC labels the component in stock, but that status does not by itself specify future replenishment time, factory allocation, or the delivery commitment for a particular quantity. Request a written quotation and stock confirmation from the selected distributor before committing a production schedule.
What can replace STM32F373CBT6?
The verified cross-reference results do not establish a guaranteed drop-in replacement for STM32F373CBT6. Same-series parts such as STM32F373CBT7 or STM32F373CCT6TR may be candidates for evaluation, but the supplied SJ Chip result explicitly says that such listings require datasheet and pinout checks and are not automatic drop-in replacements. Do not substitute a part solely because it is also an STM32F3 device; compare package pins, memory, clock, peripherals, voltage, temperature, and software support.
Is STM32F373CBT6 the same as STM32F372CBT6TR?
No definitive equivalence is established by the supplied data. The comparison search identifies STM32F372CBT6TR as another STMicroelectronics Cortex-M4-class MCU with similar headline information, but it does not provide a verified pin-by-pin comparison for the STM32F373CBT6's 48-LQFP package. Treat STM32F372CBT6TR as an engineering-review candidate only until STMicroelectronics documentation confirms identical pinout, electrical behavior, memory, peripherals, and qualification.
When should I choose STM32F373CBT6 over a lower-cost STM32 MCU?
Choose STM32F373CBT6 when a design benefits from the verified 72 MHz ARM Cortex-M4 core, FPU, 128 KB Flash, and compact 48-LQFP package. These verified resources can justify a higher-complexity controller for real-time control, signal processing, or communication-oriented embedded logic. A lower-cost MCU may be preferable when the application does not need the Cortex-M4 processing capability, but the supplied data does not establish a complete cost or peripheral comparison.
Is STM32F373CBT6 suitable for industrial control applications?
The STM32F373CBT6 can be considered for industrial control designs that fit its verified 72 MHz Cortex-M4 performance, FPU, 128 KB Flash, and 48-LQFP footprint. Industrial suitability still depends on the device's confirmed operating-temperature range, supply voltage, analog performance, communication interfaces, EMC behavior, and long-term availability; those details are not supplied in the verified snippets and must be checked in the manufacturer datasheet.
STM32F373CBT6 vs STM32F372CBT6TR - which is better for a 72 MHz control design?
The supplied comparison results show that STM32F373CBT6 and STM32F372CBT6TR are related 72 MHz ARM Cortex-M4-class STMicroelectronics options, but they do not provide enough verified information to declare one universally better. STM32F373CBT6 is confirmed as the target 128 KB Flash, 48-LQFP part; select the alternative only after checking its exact pinout, peripherals, memory map, electrical limits, and software compatibility. For a new design, use the device whose official datasheet matches every required peripheral.
How should engineers design the STM32F373CBT6 power and decoupling layout?
The supplied data does not include the STM32F373CBT6 electrical limits or reference-layout drawing, so exact capacitor values, voltage tolerances, and placement distances cannot be fabricated. As a design practice, follow the power, grounding, decoupling, and exposed-pad guidance in the STMicroelectronics datasheet and reference manual, keep high-current return paths compact, and verify the 48-LQFP footprint and thermal-pad requirements against the official package drawing. Confirm all values before PCB release.

Notas de projeto

Do not design the power rail from distributor summaries alone. Confirm the STM32F373CBT6 supply-voltage limits, internal regulator behavior, power-consumption limits, brownout behavior, and decoupling requirements from STMicroelectronics documentation. Place required input and output capacitors according to the official reference layout, keep the return path short, and verify that adjacent signal and switching-current paths do not inject noise into sensitive analog or timing circuits.

Thermal design cannot be finalized from the supplied 48-LQFP package name alone because the verified data does not provide junction-temperature limits, thermal resistance, or exposed-pad construction. Check the official package drawing and electrical characteristics, provide copper and vias only as recommended by STMicroelectronics, and calculate the worst-case temperature rise from the actual switching and I/O load before approving the board stack-up.

The 48-LQFP footprint is exposed to assembly and inspection, but layout quality still depends on clean power distribution, controlled return currents, and correct pin multiplexing. Verify the complete pinout against the STM32F373CB documentation, reserve programming and debug access, and avoid routing high-current or fast-switching signals beneath sensitive analog sections. Check land pattern, pin-1 orientation, and any exposed-pad connection against the manufacturer drawing rather than a generic LQFP footprint.

Do not treat an STM32F3-family match as an automatic drop-in replacement. Even same-package candidates can differ in flash size, RAM, clock details, peripherals, pin multiplexing, voltage limits, temperature grade, and software identifiers. Compare the official datasheets and errata first, then verify boot, debug, programming, and peripheral compatibility. The supplied cross-reference results do not establish a confirmed drop-in replacement for STM32F373CBT6.
