STM32G474VET3 - 170MHz Cortex-M4F MCU 512KB LQFP-100 | ST
MPN： STM32G474VET3 ✓ 啟用中STM32G474VET3 概覽
An Arm Cortex-M4 microcontroller is a 32-bit RISC processor core designed for deterministic real-time embedded control, with single-precision floating-point, DSP extensions, and a tightly-coupled NVIC for low-latency interrupt handling. Within the broader taxonomy, this part belongs to the MCU -> microcontroller -> semiconductor category, and to ST's STM32G4 series, which adds a CORDIC math accelerator and FMAC filter-math accelerator that offload trigonometric and FIR/IIR computations from the CPU for digital power conversion and motor-control loops.
Key features include five 12-bit ADCs sampling at 4 MSPS with hardware oversampling to 16-bit effective resolution, four 12-bit DAC channels, seven comparators, six op-amps with programmable gain, four 184 ps resolution high-resolution timer channels, USB 2.0 Full-speed with PHY, CAN-FD, three SPI, three I2C, two UART/LPUART, an SDMMC package interface, and a math accelerator block (CORDIC + FMAC). The 100-LQFP exposes 81 GPIO across five voltage-tolerant 5V-tolerant I/O banks.
The STM32G474 architecture pairs the Cortex-M4F core with ST's adaptive real-time ART Accelerator and a multi-bank Flash controller that delivers zero-wait-state execution from Flash at 170 MHz. The integrated op-amps and comparators are tightly coupled to the high-resolution timer to form current-shunt and BEMF sensing loops without external analog ICs, enabling compact, BOM-light field-oriented-control (FOC) motor drives and LLC/PSFB digital power stages.
Typical applications include digital switched-mode power supplies (LLC, PSFB, totem-pole PFC), field-oriented-control motor drives for industrial servos and e-bikes, solar inverters and battery management, USB-C PD controllers, LED lighting controllers, and industrial sensor hubs. The math accelerator is particularly valuable in these loops because CORDIC evaluates sin/cos/atan in as few as 15 cycles.
When designing with this device, place a 100 nF decoupling capacitor on each VDD pin within 2 mm of the package, plus a 4.7 uF bulk cap on the regulator input. Reserve PB8/PB9 for the bootloader or ensure they are not pulled low at reset if you intend to boot from Flash.

典型應用
STM32G474VET3 適用於 7 應用s: Digital Switched-Mode Power Supply (LLC/PSFB), Field-Oriented Control Motor Drives, Solar Inverters and Battery Management, USB-C Power Delivery Source/Sink Controllers, Industrial Sensor Hubs and IO-Link Masters, Digital LED Lighting and Stage Controllers, E-Bike and Small EV Motor Controllers.
Digital Switched-Mode Power Supply (LLC/PSFB)
The STM32G474VET3 fits digital LLC and phase-shifted full-bridge (PSFB) power supplies because its Cortex-M4F runs CORDIC math in as few as 15 cycles, enabling 100 kHz+ control loops with FMAC-backed digital filtering. The high-resolution timer delivers 184 ps duty-cycle resolution - critical for valley switching and ZVS detection that boost efficiency above 96 percent in server and EV-charger PSUs. Five 12-bit ADCs at 4 MSPS sample primary current, secondary voltage, and resonant tank signals simultaneously with hardware oversampling, eliminating an external ADC ASIC. Built-in op-amps and comparators handle current-shunt amplification and cycle-by-cycle overcurrent without external analog. The 512 KB Flash holds full DMC and DPFC firmware plus telemetry logs. Compared to a discrete DSP + FPGA solution, this single-chip design cuts BOM by $2 to $4 per board.
推薦
Field-Oriented Control Motor Drives
The STM32G474VET3 is ideal for industrial servo and BLDC/PMSM motor drives because the integrated CORDIC + FMAC block accelerates Park/Clarke transforms and field-weakening math, while the 184 ps high-resolution timer generates center-aligned PWM with sub-microsecond dead-time insertion. Six on-chip op-amps handle three-phase current sensing without external amplifiers, and seven comparators trip hardware overcurrent in under 50 ns. The 100-LQFP exposes enough GPIO to drive three half-bridges plus encoder, Hall, or resolver feedback. With 213 DMIPS at 170 MHz, this part runs ST's motor-control SDK reference firmware including sensorless FOC at speeds up to 60,000 RPM. The Cortex-M4F FPU ensures smooth torque control under high-dynamic-load conditions typical of robotic joints and CNC axes.
推薦
Solar Inverters and Battery Management
For photovoltaic string inverters and residential battery management systems, the STM32G474VET3 integrates MPPT calculation, grid-synchronization PLL, and battery-cell monitoring in a single chip. CORDIC accelerates the sin/cos transforms required for SOGI-FLL phase-locked loops used in grid-tie synchronization to IEC 62116 anti-islanding requirements. The 4 MSPS ADCs with hardware oversampling read DC-bus voltage and current with 0.05 percent accuracy, which is essential for 99 percent CEC-weighted inverter efficiency. Five 5V-tolerant I/O banks interface directly to CAN-FD battery stack BMS communication, while the SDMMC package interface logs fault history and energy-yield data to an SD card. USB Full-Speed enables on-site firmware updates and inverter commissioning via ST's commissioning tool.
推薦
USB-C Power Delivery Source/Sink Controllers
USB-C PD source controllers using the STM32G474VET3 leverage its USB 2.0 Full-speed PHY, 5x fast ADCs for VBUS/VCONN sensing, and 4x DACs that drive analog PWM-controlled buck/boost stages. ST's certified X-CUBE-USB-PD library supports PPS, AVS, and EPR 28V/36V/48V profiles, so a single firmware image handles 100W laptop chargers and 240W EPR sink devices. The CORDIC accelerator computes the cubic polynomials used for programmable supply voltage (PPS) ramp profiles in under 1 microsecond, while the FMAC block provides the digital-loop compensation. The 512 KB Flash accommodates the full USB-PD stack with policy engine, source/sink protocol, and alternate-mode negotiation for DisplayPort and Thunderbolt tunneling.
推薦
Industrial Sensor Hubs and IO-Link Masters
Industrial sensor hubs and 4-port/8-port IO-Link masters benefit from the STM32G474VET3's 170 MHz compute and 5x 12-bit ADCs with hardware oversampling, which can condition up to 8 analog sensor inputs simultaneously. Three SPI each I/O and three I2C each I/O ports handle the IO-Link COM3 (230.4 kbaud) channels, while the high-resolution timer drives the IO-Link wake-up pulse with sub-microsecond accuracy. Built-in op-amps and comparators implement 4 mA to 20 mA current-loop analog input stages for legacy sensor migration to digital IO-Link masters. The 128 KB SRAM buffers vibration and process data streams for Industry 4.0 edge analytics. CAN-FD uplink aggregates sensor data to the higher-level PLC or industrial Ethernet gateway.
推薦
Digital LED Lighting and Stage Controllers
High-end architectural and stage LED controllers using the STM32G474VET3 benefit from its 184 ps high-resolution timer to generate smooth 16-bit dim curves that match the human eye's logarithmic brightness perception. Five 12-bit DACs drive up to five independent LED string constant-current regulators via analog control loops. The Cortex-M4F DSP extensions and FMAC accelerator implement real-time CIE 1931 xy color-mixing and gamma-correction math for stage lighting where 16 million colors must transition in under 50 ms. The USB 2.0 Full-speed interface accepts DMX-over-USB input from the keyboard, and CAN-FD connects to inter-rack synchronization busses. The 100-LQFP footprint fits inside 1U rack lighting controllers.
推薦
E-Bike and Small EV Motor Controllers
Compact e-bike and small-EV motor controllers use the STM32G474VET3 to consolidate torque-control FOC, battery management, and HMI on a single chip. The 6 internal op-amps handle three-phase shunt current sensing without external amplifiers, reducing BOM cost by $1.50 per controller. CORDIC acceleration keeps sensorless FOC loop times under 20 microseconds at 170 MHz, supporting pedal-assist response times under 100 ms as required by EN 15194. The high-resolution timer manages MOSFET dead-time insertion and regenerative braking PWM, while 5V-tolerant GPIO directly interfaces to the throttle, brake, and pedal-torque sensors. CAN-FD uplink connects to the dashboard or fleet telematics unit.

設計說明
The STM32G474VET3 has 5 VDD/VSS pairs plus dedicated VDDA/VSSA. Place a 100 nF X7R 0402 ceramic decoupling capacitor on each VDD pin within 2 mm of the package, plus a 4.7 uF X5R bulk capacitor shared across the supply rail. The VDDA pin requires a separate low-noise LDO or ferrite-bead filtered 3.3 V, plus a 1 nF + 100 nF decoupling pair to minimize ADC sampling noise. Connect unused VDD pins to the supply and unused VSS pins to ground - never leave them floating - to avoid ESD paths and erratic reset behavior.
Estimated: at full 170 MHz operation driving multiple peripherals, the STM32G474VET3 consumes approximately 90 mW (core + peripherals) from a 3.3 V supply. The LQFP-100 14x14 mm package has theta_JA around 50 C/W on a 4-layer JEDEC PCB, giving a 4.5 C junction rise - well within the 125 C limit. If your design runs at sustained 125 C ambient, derate the clock frequency or add a copper heatsink pad beneath the exposed pad region. Industrial-grade STM32G474VET3 (suffix 3) guarantees operation from -40 C to +125 C.
Keep the high-resolution timer PWM traces (PA8-PA12, PB0-PB1, PE9-PE15) as short as possible and avoid running them parallel to sensitive ADC analog traces (PA0-PA7). Use a 4-layer PCB with a continuous ground plane beneath the LQFP-100 to provide both thermal spreading and a low-impedance return path for high-frequency signals. Place the 32.768 kHz crystal on PC14/PC15 within 5 mm of the pins with a grounded guard ring. The HSE crystal (typically 8 MHz) on PD0/PD1 or PF0/PF1 should also be guarded and supplied by a clean analog-domain supply to reduce PLL jitter.
Do not pull PB8 low at reset - this selects a serial-boot mode that may prevent application code from running. If you boot from Flash and need PB8 for GPIO, ensure the boot pin is in a defined state by reset. The CAN-FD peripheral requires an external transceiver (e.g. TLE9251V) - the STM32G474VET3 has only the protocol controller, not the physical layer. Boot from user Flash by setting BOOT0=0 with a 10 kohm pull-down.
