STM32G474RCT3 概述
A microcontroller is a programmable semiconductor that integrates a CPU, memory, peripherals, and communication interfaces on one device. The STM32G4 family belongs to the embedded MCU hierarchy and is designed for real-time control, sensing, signal processing, and connected industrial equipment. Its Cortex-M4F core supports efficient control-loop execution while on-chip peripherals reduce external component requirements.
Verified listings identify a 170 MHz operating frequency, up to 512 KB Flash for the broader STM32G474 family, 128 KB SRAM, a math accelerator, and a 184 ps high-resolution 12-channel timer. For the exact STM32G474RCT3, DigiKey specifies 256 KB Flash and a 64-LQFP package. The product is positioned for digital power conversion, motor control, industrial automation, communications, and precision analog measurement.
The STM32G474 device family combines high-resolution timer capability with rich analog peripherals, making it useful where accurate edge timing, fast control loops, and mixed-signal measurements are important. At 170 MHz, the listed device reaches 213 DMIPS according to the available datasheet listing. These figures describe processing capability, not application throughput; actual performance depends on code, memory configuration, peripherals, and clock settings.
Typical applications include digitally controlled power supplies, motor-drive control, sensor acquisition, programmable signal generation, industrial controllers, and communication-enabled embedded systems. The 64-LQFP package provides a conventional leaded surface-mount footprint that is practical for prototypes, inspection, and designs requiring accessible pins.
Designers should verify supply voltage, pin multiplexing, clock-tree settings, analog-reference requirements, and exposed-pin behavior against the official datasheet before layout. Do not infer unverified electrical limits from family-level descriptions. Firmware migration also requires checking peripheral instances, interrupt mappings, and package-dependent pin assignments.
This product record combines verified distributor specifications, the official STMicroelectronics family page, package information, practical engineering guidance, and qualified replacement analysis. It is intended to accelerate component selection while keeping unverified parameters and replacement assumptions explicit.

典型应用
STM32G474RCT3 适用于 6 应用s: Digital Power Conversion, Motor Drive Control, Industrial Sensor Acquisition, Programmable Signal Generation, Communications Gateway, Test and Measurement Equipment.
Digital Power Conversion
STM32G474RCT3 fits digital power-conversion control because its verified 170 MHz Arm Cortex-M4F core supports fast control-loop execution, while the family listing identifies rich analog resources and a 184 ps high-resolution timer. The high-resolution timing can improve PWM edge placement and measurement resolution in converter designs. Engineers can use the math accelerator to support control calculations, subject to confirming the required ADC, timer, PWM, and pin assignments in the 64-LQFP package.
推荐
Motor Drive Control
The STM32G474RCT3 is a strong candidate for motor-control systems that need deterministic timing and substantial embedded processing. The listed 184 ps high-resolution timer supports precise edge timing for PWM generation and input capture, while the Cortex-M4F core handles control algorithms and supervisory logic. The exact motor-control peripherals, complementary outputs, break input, and analog current-sense channels must be verified against the package pinout and device datasheet.
推荐
Industrial Sensor Acquisition
STM32G474RCT3 can serve as the central controller in industrial sensor-acquisition equipment because it combines a 170 MHz 32-bit core, 128 KB SRAM, and rich analog resources. These resources are useful for sampling, filtering, calibration, and communications in a compact embedded design. Use the official documentation to confirm ADC resolution, sampling characteristics, trigger routing, reference voltage, and package-level analog pin availability before selecting the MCU.
推荐
Programmable Signal Generation
The STM32G474RCT3 is suitable for precision signal-generation and measurement products because its high-resolution timer provides 184 ps resolution for fine timing and edge placement. The 170 MHz Cortex-M4F processor can manage sequencing, data handling, and user-interface logic while the SRAM supports local buffering. Confirm timer channels, DMA routing, DAC availability, and clock requirements in the exact device configuration before finalizing the design.
推荐
Communications Gateway
STM32G474RCT3 can be used in a communications gateway or protocol-conversion device when local control, analog monitoring, and deterministic timing are required. Its 170 MHz Cortex-M4F core provides substantial processing headroom, and the 128 KB SRAM can support buffering and protocol state. The available verified data does not specify a particular Ethernet, USB, or CAN configuration for the exact suffix, so peripheral availability and pin multiplexing must be checked in the official documentation.
推荐
Test and Measurement Equipment
STM32G474RCT3 is a practical fit for embedded test and measurement equipment that combines timing, control, and signal conditioning. The high-resolution timer supports precise stimulus or measurement intervals, while the Cortex-M4F core can run control, calibration, and communication software. The exact ADC, comparator, timer-channel, and interface assignments must be checked for the 64-LQFP package, and the power and reference network should follow the official application guidance.

- Processing performance （对比 STM32G474RET6)
- Memory configuration transparency （对比 STM32G474RET6U)
设计说明
Before routing, compare the STM32G474RCT3 package drawing with the exact pin table and confirm every power, ground, clock, debug, analog, and timer connection. The supplied verified data confirms a 64-LQFP 10 x 10 mm package but does not include the complete pinout. Keep decoupling pins close to their intended ground references and preserve the package-specific land pattern rather than reusing a generic LQFP footprint.
Do not treat every STM32G474 orderable suffix as interchangeable. The verified target listing specifies 256 KB Flash, while the broader family is described as supporting up to 512 KB Flash. Related MPNs may also differ in package suffix, memory, temperature range, or ordering code. Validate the exact MPN against the official datasheet, boot configuration, peripheral options, and PCB footprint before releasing a replacement to production.
For high-resolution timer and control-loop designs, treat clock distribution, analog references, power-supply return paths, and timing-critical nets as layout priorities. The listed 184 ps timer resolution is a device feature, not a guaranteed system-level measurement resolution. Actual timing accuracy also depends on the clock source, PLL configuration, interrupt latency, firmware, PCB propagation delay, and measurement method.
合规信息
The supplied data does not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status for this exact MPN. Compliance must be confirmed from the current STMicroelectronics product documentation or supplier certificates.
