STM32G473VET3 - 170MHz Cortex-M4 MCU 512KB LQFP-100 | STMicroelectronics
MPN: STM32G473VET3 ✓ AktifSTM32G473VET3 Ringkasan
A Cortex-M4 microcontroller is a 32-bit RISC processor core designed by Arm that includes a single-precision floating-point unit (FPU) and DSP extensions. The Cortex-M4 sits within the broader Cortex-M family and feeds into the wider STM32 portfolio, which scales from ultra-low-power Cortex-M0+ devices up to Cortex-M7 high-performance parts. Compared with Cortex-M3 parts, the M4 adds DSP SIMD instructions, single-cycle MAC, and an optional FPU, enabling higher-throughput signal processing and mathematical acceleration at modest clock speeds.
Key features of the STM32G473VET3 include up to 512 KB single-bank Flash with ECC and 128 KB SRAM with parity, a 12-channel DMA, two 16-bit advanced timers plus a 32-bit timer, four 16-bit general-purpose timers, two HRTIM masters, multiple USART/UART, SPI, I2C, FDCAN, USB 2.0 FS, and a real-time clock. The integrated Cordic accelerator (rotation, sine/cosine) and FMAC (filter math) offload DSP tasks, while the comparators, op-amps, and 12-bit DACs allow direct analog control loops on-chip. The 100-pin LQFP package exposes the full peripheral set, including the external memory bus and additional GPIO.
Typical applications span industrial motor drives (FOC for PMSM/BLDC), digital SMPS and power conversion, lighting controls, solar micro-inverters, factory automation, and sensor-rich IoT nodes. On-board comparators, op-amps, and high-resolution timers let the part close a current-mode control loop without external analog components, while the FPU and Cordic enable sensor fusion and field-oriented control without taxing the CPU. The LQFP-100 footprint also suits hand-prototyping and field-repair scenarios where rework is more practical than BGA.
When designing with this device, ensure the 1.8V/2.5V/3.3V rails are well-decoupled with 100nF + 4.7uF ceramic capacitors near each VDDA/VSS pair, and route the HSE 8-25 MHz crystal traces symmetrically to minimise jitter. Configure the math accelerator and DMA priorities in the CubeMX configuration to avoid conflicts, and consult the reference manual for Flash Option Byte programming to enable the desired read/write protection at production time.

Aplikasi Umum
STM32G473VET3 cocok untuk 6 aplikasis: Industrial Motor Drives (FOC), Digital SMPS and Power Conversion, Lighting and LED Drivers, Solar Micro-Inverters and MPPT, Factory Automation and Sensor Fusion, Medical and Diagnostic Devices.
Industrial Motor Drives (FOC)
The STM32G473VET3 fits three-phase PMSM and BLDC field-oriented control because it combines a 170 MHz Cortex-M4 with FPU, Cordic/FMAC trigonometric offload, three synchronized 12-bit ADCs timed for current sensing, and 1.7 ns advanced timers with complementary PWM and dead-time insertion. The on-chip comparators can trigger emergency shut-down directly without an external analog IC. Compared with Cortex-M0 solutions, the FPU and DSP extensions double current-loop bandwidth at the same clock. The LQFP-100 footprint exposes the full peripheral set including the SD card interface for parameter logging.

Digital SMPS and Power Conversion
The STM32G473VET3 supports digital power topologies up to ~200 kHz switching frequency using its advanced timers with complementary outputs, on-chip comparators for peak-current mode control, four 12-bit DACs for slope compensation, and the Cordic accelerator for trigonometric math. For higher switching frequency above 200 kHz where sub-nanosecond timing resolution matters, the STM32G474VET3 in the same LQFP-100 footprint adds an HRTIM. The 100-pin LQFP package allows hand-reworkable prototypes during power supply design validation.
Direkomendasikan
Lighting and LED Drivers
The STM32G473VET3 drives multi-channel LED lighting including DALI, DMX, and tunable-white systems by leveraging 12-bit DACs for smooth dimming, HRTIM-style timer resolution on the advanced timers, and up to 87 GPIO for large LED matrix multiplexing. The integrated op-amps close current-sense loops without external components, reducing BOM cost. The Cortex-M4 with FPU computes CIE-1931 color correction and gamma curves faster than Cortex-M3 at the same clock, simplifying high-channel-count LED fixtures.
Direkomendasikan
Solar Micro-Inverters and MPPT
The STM32G473VET3 hosts perturb-and-observe / incremental-conductance MPPT algorithms using its FPU for fast floating-point math, on-chip 12-bit ADCs for panel voltage and current sensing, and FDCAN for grid-side communication. The Cordic engine accelerates the trigonometric math needed for PLL grid synchronization. With 512 KB Flash it can run a complete grid-tie control stack including anti-islanding protection in a single chip, eliminating the need for an external DSP. The LQFP-100 footprint allows field retrofits on micro-inverter PCBs.
Direkomendasikan
Factory Automation and Sensor Fusion
The STM32G473VET3 acts as a sensor-fusion hub in industrial PLC and IO-Link master designs by combining FPU-accelerated quaternion math, up to 5 SAR ADCs for analog sensor channels, multiple UART/SPI/FDCAN peripherals for fieldbus connectivity, and 512 KB Flash for protocol stacks. The Cordic/FMAC accelerators offload the trigonometric inner loop typical of IMU fusion, freeing CPU for PLC cycle work. The 100-pin LQFP exposes the full peripheral count needed for multi-protocol IO-Link masters.
Direkomendasikan
Medical and Diagnostic Devices
The STM32G473VET3 fits low-end medical and diagnostic instrumentation such as blood-pressure monitors, infusion pumps, and patient monitors requiring deterministic real-time response. The Cortex-M4 with FPU executes DSP filter chains (FIR, IIR) for ECG and pulse-oximetry signal conditioning, while on-chip op-amps condition analog front-end signals without external analog ICs. The 100-pin LQFP footprint supports prototypes that need FDA/IEC 62304 design history, and the LQFP package simplifies verification and re-spin during design validation.

Diferensiator Kunci
- Same LQFP-100 footprint as G474 with full peripheral set retained (vsSTM32G474VET3)

- Mainstream Cortex-M4 with FPU and DSP at 170 MHz (vsSTM32G484VET3)
Catatan Desain
The STM32G473VET3 requires separate analog (VDDA/VSSA) and digital (VDD/VSS) supplies. Place a 100 nF X7R ceramic capacitor on each VDD pin plus a bulk 4.7 uF within 10 mm, and a ferrite bead between VDD and VDDA to suppress digital switching noise on the ADC reference. VBAT must be tied to VDD when no battery backup is used, otherwise RTC and backup registers will lose state. The on-chip voltage regulator requires an external 1 uF + 100 nF on VCAP pins.
Layout: route the HSE 8-25 MHz crystal traces symmetrically and keep them within 5 mm of OSC_IN/OSC_OUT with a ground guard ring. The LQFP-100 power pad (if exposed) should be soldered to a copper pour of at least 50 mm^2 for thermal relief. Avoid routing high-current PWM traces adjacent to ADC input traces; insert a ground trace between them. SDRAM and parallel bus pins should be length-matched within 1 mm for reliable operation above 80 MHz.
Common pitfalls: (1) the BOOT0 pin state at reset selects the boot source - leave it tied to GND through a 10 k resistor for normal Flash boot. (2) The HSE bypass capacitors must be sized per crystal load capacitance; wrong values cause oscillator start-up failure. (3) When using USB FS, the DP/DM traces must be 90 ohm differential with length matching to 1 mm. (4) The math accelerator (Cordic/FMAC) requires interrupt priority lower than the DMA to avoid pipeline stalls.
