170 MHz Cortex-M4F with FPU — real-time control headroom
The STM32G474VET7 is a 32-bit single-core ARM Cortex-M4F microcontroller from ST's STM32G4 series, built for digital power conversion, motor control, and industrial automation. The 170 MHz core with single-precision floating-point unit handles nested control loops and sensor fusion without a separate DSP. Program memory is 512 KB of Flash, paired with 128 KB of SRAM — enough for complex firmware images and double-buffered data streams in field-oriented motor drives or multi-phase PFC stages.
42-channel ADC and 7-channel DAC — analog density for multi-sensor systems
Data converters include a 42-channel 12-bit ADC and a 7-channel 12-bit DAC. The ADC channel count covers simultaneous current-sense on three motor phases plus voltage, temperature, and position feedback without external muxing. The seven DAC channels can generate analog references or offset trim voltages for external sensor bridges.
Industrial temperature grade and peripheral set
The 86 I/O pins in the 100-LQFP package leave room for parallel LCD interfaces or multiple encoder inputs.
ST lists the STM32G474VET7 as Active. The base product number STM32G474 covers a density-and-package family, so if a future board shrink needs a smaller footprint, a pin-compatible sibling in the same series is the natural cross-grade — not a respin.
