STM32G474CEU6 - 170MHz 512KB Cortex-M4F MCU | STMicroelectronics
MPN: STM32G474CEU6 ✓ AktifSTM32G474CEU6 Ringkasan
An Arm Cortex-M4F microcontroller is a 32-bit embedded processor based on the RISC architecture, with a single-precision floating-point unit for hardware-assisted mathematical operations. Within the product hierarchy, the STM32G474CEU6 belongs to the STM32G4 family of high-performance microcontrollers, combining general-purpose processing with analog, timer, communication, and real-time control peripherals in one integrated device.
The verified product information identifies three principal features: a maximum clock frequency of 170 MHz, 512 KB of Flash organized as 512K x 8, and a 48-pin UFQFPN package. Additional listed capabilities include math acceleration and high-resolution timers. These resources distinguish it from simpler general-purpose Cortex-M devices when an application requires intensive control calculations, precise timing, or floating-point signal processing.
The Cortex-M4F core provides a deterministic architecture with an integrated FPU, while the STM32G4 feature set targets applications where response time and control accuracy matter. The 213 DMIPS figure stated in the verified datasheet listing indicates high computational throughput for its class, although total application performance depends on clock configuration, memory implementation, peripherals, and firmware optimization.
Typical uses include digital power conversion, industrial motor control, sensor acquisition, compact industrial gateways, and real-time embedded controllers. The 170 MHz processing rate can support computationally intensive loops, while the high-resolution timer resources improve measurements and edge-based control. Its low-pin-count UFQFPN package also enables compact layouts when space is constrained, although careful exposed-pad and thermal management is required.
Designers should verify the complete pin configuration, exposed-pad connection, decoupling requirements, clock options, and peripheral assignments in the official STM32G474CE datasheet before layout release. Because the verified data does not provide operating-temperature, memory-voltage, ADC, communications, and compliance details, those specifications require confirmation rather than assumption during component qualification.
This product record consolidates the verified manufacturer and distributor data for the STM32G474CEU6 with package information, engineering application guidance, a conservative replacement assessment, and transparent data gaps. It is intended to accelerate sourcing and initial design review while ensuring that unqualified claims are independently checked against the manufacturer documentation.

Aplikasi Biasa
STM32G474CEU6 patut untuk 6 aplikasis: Industrial Motor Control, Digital Power Conversion, Industrial Sensor Acquisition, Real-Time Communications Gateway, Precision Timing and Measurement, Compact Embedded Control Board.
Industrial Motor Control
The STM32G474CEU6 fits compact motor-control systems that require fast computation, deterministic timing, and a space-efficient package. Its verified 170 MHz Arm Cortex-M4F core provides an FPU and up to 213 DMIPS, allowing current-loop and control calculations to run with less impact from arithmetic load. The listed high-resolution timer capability is valuable for capturing pulse edges and producing precisely timed control events. Place the MCU near the power stage and preserve clean return paths, especially when PWM outputs drive power devices. Final suitability depends on the ADC, comparator, timer channels, operating temperature, and safety requirements specified in the complete manufacturer datasheet.
Digital Power Conversion
The STM32G474CEU6 is a strong candidate for digital power-conversion controllers requiring substantial control-loop computation in a compact 48-pin package. Its 170 MHz Cortex-M4F core and 213 DMIPS listing support rapid voltage and current regulation calculations, while the FPU assists with scaling and filtering operations. The 512 KB of Flash provides room for control code, parameter tables, and diagnostics, and the 128 KB of RAM supports working state and buffers. Engineers must still verify the ADC accuracy, timer resolution, DAC availability, operating limits, and fault-routing functions. Thermal design around the UFQFPN exposed pad and clean separation of analog and digital return paths are essential.
Industrial Sensor Acquisition
The STM32G474CEU6 can serve as the processing center in an industrial sensor-acquisition node where signals require filtering, scaling, and real-time interpretation. The verified 170 MHz Arm Cortex-M4F platform can execute digital filters and control algorithms efficiently, while the 512 KB of Flash and 128 KB of RAM provide useful storage for calibration data and acquisition buffers. Math acceleration may assist selected numeric operations, although the exact accelerator behavior must be confirmed in the manufacturer documentation. The compact 7 x 7 mm UFQFPN helps minimize board area. Before design release, verify ADC resolution, sampling rate, analog supply range, noise performance, sensor interfaces, and calibrated accuracy requirements.
Real-Time Communications Gateway
The STM32G474CEU6 is appropriate for compact real-time gateways that must combine communications, protocol processing, and local control. Its 170 MHz Cortex-M4F core offers substantially more headroom than entry-level Cortex-M devices for buffering, framing, encryption-related computation, and concurrent peripheral servicing. The listed 1.8 V, 2.5 V, and 3.3 V supply options can simplify interface planning across industrial and embedded systems. The 48-pin UFQFPN footprint supports space-constrained designs, although communications peripherals, pin multiplexing, DMA behavior, and package-specific assignments must be checked against the complete datasheet. Keep high-speed signals routed away from sensitive analog inputs and maintain continuous ground references beneath the exposed pad.
Precision Timing and Measurement
The STM32G474CEU6 fits precision timing and measurement systems because the verified feature set includes high-resolution timers alongside a 170 MHz Cortex-M4F processor. The core can execute measurement algorithms and control logic while dedicated timer resources handle precise edge capture, waveform generation, and elapsed-time measurement. The 512 KB of Flash permits substantial firmware and calibration-table storage, and the 128 KB of RAM supports capture buffers and working algorithms. Designers should confirm timer resolution, trigger routing, capture limits, clock tolerance, and peripheral interconnect behavior in the manufacturer documentation. Crystal, oscillator, and external-reference layout should follow the official guidance to prevent timing jitter and frequency errors.
Compact Embedded Control Board
The STM32G474CEU6 is useful for compact embedded control boards that need more compute capacity without adopting a larger microcontroller package. Its 48-pin UFQFPN 7 x 7 mm construction reduces board footprint, while 512 KB of Flash, 128 KB of RAM, and a 170 MHz core provide a capable platform for sequencing, diagnostics, and user-interface handling. The three listed supply-voltage options offer flexibility in mixed-voltage designs. Because the verified excerpts do not enumerate GPIO count, ADC channels, communication interfaces, or package dimensions, engineers must verify those details before schematic capture. Include the exposed-pad land pattern, thermal vias, and manufacturer-prescribed decoupling from the outset.

Catatan Desain
Treat the exposed pad as a mandatory thermal and electrical design feature rather than an optional copper area. Use the manufacturer land pattern, exposed-pad dimensions, solder-mask opening, and recommended via geometry from the STM32G474CE package documentation. Maintain a continuous ground reference where the official drawing permits it, distribute thermal vias evenly, and avoid thermal-via placement conflicts with sensitive signal routes. Validate the final junction-temperature margin under worst-case clock, ambient, and I/O loading; the supplied excerpts do not provide thermal resistance data.
Reserve all 48 package pins according to the official UFQFPN footprint and verify every alternate function before schematic release. Place required input, output, VDD, and VSS decoupling capacitors close to their assigned pins, following the capacitance and voltage constraints in the manufacturer datasheet. Keep switching-node copper and high-current return paths away from ADC or timing-sensitive nets. Because no pin table or recommended land-pattern dimensions were included in the supplied data, do not derive them from generic UFQFPN drawings.
A shared Cortex-M4F core or matching 48-pin package does not by itself prove that a replacement is electrically interchangeable. For STM32G474CEU3 and STM32G473CEU6, verify ordering-code temperature grades, supply limits, flash and RAM organization, ADC and timer features, communications peripherals, interrupt mappings, debug support, and qualification status. Firmware may also require device-family configuration changes. Perform a timing, brownout, clock, and peripheral regression test before approving either part as a drop-in substitute.
Maklumat Kesediaan
The supplied verified excerpts do not contain explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. AEC-Q100 is marked not_applicable because this industrial/consumer STM32G4 ordering code is not identified as an automotive-qualified variant.
