STM32G473RBT6 - 170MHz Cortex-M4 MCU | STMicroelectronics
Teilenummer: STM32G473RBT6 ✓ AktivSTM32G473RBT6 Übersicht
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals on one device. Within the embedded-computing hierarchy, the STM32G473RBT6 is an Arm Cortex-M4 MCU, a 32-bit RISC controller, and a member of STMicroelectronics' STM32G4 mainstream series. It is intended for applications in which real-time control, analog measurement, communications, and general-purpose embedded processing must share one device.
The verified device features include a maximum clock frequency of 170 MHz, 128 KB of Flash, and an LQFP-64 package. STMicroelectronics describes the G473 family as having high analog integration, and distributor records also identify the math accelerator. The Arrow listing specifies operation with 1.8 V, 2.5 V, and 3.3 V supply options. Exact RAM capacity, ADC characteristics, timer counts, communication peripherals, and electrical limits require confirmation in the manufacturer datasheet.
The Cortex-M4 architecture supports efficient interrupt-driven control while the math accelerator can reduce the processing burden of suitable arithmetic-intensive routines. High analog integration can simplify designs that require both control logic and analog interfaces, although the exact converter resolution, sampling rate, bandwidth, and internal references must be checked against the selected STM32G473 device variant. Firmware configuration, peripheral assignment, and board-level qualification remain product-specific.
Typical uses include industrial motor and power-control systems, precision data-acquisition equipment, communications equipment, and compact embedded automation controllers. The 10 mm by 10 mm LQFP-64 package is also useful for prototypes and designs that prefer a leaded, inspectable package over a very small ball-grid-array option. The available evidence does not establish the complete peripheral mix or package-specific thermal limits.
Designers should verify the 64-pin pinout, exposed programming and debug functions, supply sequencing, decoupling requirements, and analog input ranges before layout. Firmware migration from another STM32 family should be assessed at the register, peripheral, and driver level rather than inferred solely from the Cortex-M4 designation. This page distinguishes verified facts from parameters that still require datasheet confirmation.
This page consolidates manufacturer and distributor evidence, procurement data, comparison guidance, and practical design cautions. It also identifies where package, electrical, and alternative-part claims require independent verification rather than treating generic MCU compatibility as proof of a drop-in replacement.

Typische Anwendungen
STM32G473RBT6 ist geeignet für 6 Anwendungs: Industrial Motor Control, Precision Data Acquisition, Communications Controller, Embedded Automation Controller, Power Conversion Control, Portable Instrumentation.
Industrial Motor Control
The STM32G473RBT6 fits real-time motor-control prototypes that require more processing capability than a basic microcontroller. Its verified 170 MHz Arm Cortex-M4 core provides headroom for control-loop calculations, while the math accelerator can assist suitable arithmetic operations and high analog integration supports mixed-signal sensing. The 64-pin LQFP package is useful where visible leads and a 10 mm x 10 mm footprint simplify prototype assembly. Before selecting it for a specific motor drive, verify timer channels, PWM resolution, ADC characteristics, control-loop peripherals, and the operating-temperature grade in the manufacturer datasheet. Firmware should also be validated against the exact peripheral configuration rather than relying only on the Cortex-M4 designation.
Empfohlen
Precision Data Acquisition
The STM32G473RBT6 is a strong architectural candidate for compact data-acquisition equipment because the STM32G4 family is described as providing high analog integration alongside a 170 MHz Cortex-M4 core. That combination can support signal conditioning, digital filtering, and host communication in one device, reducing component count and board area. The 64-pin LQFP-64 package also offers accessible leads for inspection and rework. Exact suitability depends on the particular G473 variant's ADC resolution, sampling rate, input bandwidth, reference accuracy, conversion timing, and channel count, none of which are quantified in the supplied evidence. Those parameters, along with analog-noise performance and calibration requirements, must be checked before defining measurement accuracy.
Empfohlen
Communications Controller
The STM32G473RBT6 can serve as the central controller in embedded communications equipment when a design values a 170 MHz Cortex-M4 core and flexible mixed-signal integration. Its processing capability is suitable for protocol handling, buffering, supervisory logic, and control-plane functions, while the LQFP-64 package can simplify access to a larger peripheral complement than smaller leaded packages. The supplied evidence does not identify the exact UART, USB, CAN, USB Type-C, or Ethernet resources on this exact order code, so none should be assumed. Before using it for a communications link, confirm peripheral availability, pin multiplexing, transceiver interface voltage, DMA channels, stack requirements, and protocol certification needs. Software architecture should isolate peripheral-dependent drivers to simplify future migration.
Empfohlen
Embedded Automation Controller
The STM32G473RBT6 is appropriate for compact automation controllers that combine real-time decision-making with analog input conditioning. Its verified 170 MHz Cortex-M4 execution capability and math accelerator provide resources for sequencing, diagnostics, and control algorithms, while high analog integration can simplify signal acquisition around sensors and actuators. The 64-lead LQFP package makes the part attractive for prototypes, educational platforms, and industrial boards where solderability and visual inspection matter more than the smallest possible footprint. Selection must remain grounded in the exact datasheet: verify I/O count, ADC performance, timers, communication interfaces, supply range, and brownout behavior. Also confirm whether the application requires a wider temperature grade or functional-safety evidence beyond what is supplied here.
Empfohlen
Power Conversion Control
The STM32G473RBT6 is a credible candidate for supervisory and digital-control functions in power-conversion systems because the verified 170 MHz Cortex-M4 core can execute control and protection logic, and the STM32G4 family's high analog integration can reduce the need for separate signal-conditioning components. The math accelerator may benefit qualifying control calculations, although firmware profiling is required to quantify any benefit. The LQFP-64 footprint provides a practical route to prototype power boards with visible leads. Before deployment, verify the exact ADC and comparator resources, timer-advanced-control features, DAC availability, operating voltage, thermal limits, and isolation requirements. Protective functions must operate independently of firmware, and the MCU must never be the sole control element for a hazardous power stage without appropriate hardware shutdown paths.
Empfohlen
Portable Instrumentation
The STM32G473RBT6 can support portable measurement and instrumentation products where a high-performance Cortex-M4 core, math accelerator, and mixed-signal integration are needed in a compact leaded package. The 10 mm x 10 mm LQFP-64 format balances board area with prototype accessibility and offers more pins than a small leadless package. Its 128 KB Flash provides 128K x 8 of program storage, although total application capacity also depends on boot code, firmware updates, diagnostics, and the unverified RAM size. Designers should establish memory use through linker analysis and reserve space for field updates. Battery-powered designs additionally require verified sleep modes, wake-up sources, analog leakage, and active-current measurements from the datasheet, none of which are supplied in the current evidence.

Designhinweise
Do not treat the Cortex-M4 core name as proof that an MCU is a drop-in replacement. The STM32G473RBT6 and STM32G474 candidates share family-level traits, but engineers must compare the exact 64-pin package, power pins, analog pins, debug pins, oscillator connections, peripheral numbering, interrupt mapping, clock tree, and startup code before substitution.
Use only the supply range and decoupling network specified for the exact order code in the manufacturer datasheet. Although the Arrow listing identifies 1.8 V, 2.5 V, and 3.3 V supply options, that does not establish every rail, pin, sequencing, or operating-mode condition. Place required bulk and high-frequency capacitors at the pins specified by the reference design and validate startup, shutdown, and brownout behavior on hardware.
The 10 mm x 10 mm LQFP-64 footprint is straightforward to inspect but requires careful escape routing between 0.5 mm-pitch leads. Preserve the manufacturer-recommended land pattern, maintain solder-mask and paste compatibility, and route sensitive analog inputs away from switching nodes and high-current paths. Because the exact pinout is not included in the supplied evidence, do not release the layout until every pin has been checked against the official package drawing.
The STM32G474RBT3 candidate differs in its temperature-grade suffix, so it must not be treated as an automatic procurement substitution for STM32G473RBT6. Review the grade, Flash and RAM requirements, peripheral deltas, and firmware support. For a production redesign, compile and test the existing application against the alternate device, verify production programming and traceability, and obtain approval from the original component owner.
Compliance-Informationen
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
