The 81-WLCSP package (4.02x4.27 mm) saves board area but demands a capable assembly line for wafer-level chip-scale packages. The 170 MHz core speed puts this part in the upper tier of the STM32G4 family. For a field-oriented motor control loop running at 20 kHz PWM rate, that clock headroom lets you execute the full Clarke/Park transform, PI regulators, and SVPWM generation within a single interrupt window without pushing the duty cycle to the limit. The 512 KB Flash is enough to hold a complex firmware stack including a real-time OS, communication protocol stacks (CANopen, EtherCAT slave via the built-in CAN and SPI peripherals), and application code — no external memory needed for most designs. The 128 KB SRAM supports multiple data buffers for ADC conversions, lookup tables, and communication frames without tight packing. ## Analog integration — 42 ADC channels and 7 DAC channels With 42 analog-to-digital converter channels at 12-bit resolution and 7 digital-to-analog converter channels at 12-bit resolution, this MCU can replace several external data converters in a multi-sensor or multi-phase system. For a three-phase motor drive, you can dedicate three ADC channels per phase for current sensing, plus one for DC-link voltage and one for temperature — still leaving dozens of channels for auxiliary sensors. The seven DAC channels can generate analog setpoints or reference voltages for external comparators or amplifiers. This integration reduces BOM count and board area, but the 12-bit resolution sets the noise floor; if your application needs 16-bit or higher precision, an external ADC is still required. ## Connectivity and peripheral set The 67 I/O pins in the 81-WLCSP package give enough flexibility for parallel sensor interfaces or display buses. Peripherals include brown-out detect, power-on reset, DMA, I²S, PWM, and a watchdog timer — a standard set for industrial control. ## Lifecycle and sourcing This is a current-generation STM32G4 device, so long-term availability is stable for new designs. No official second source exists; the STM32G4 series is single-sourced from ST, so for supply resilience consider qualifying a pin-compatible sibling within the G4 family (e.g., a lower-density variant) as a drop-in alternative if your firmware can accommodate the memory difference.","metaTitle":"STM32G473MEY6TR ARM Cortex-M4 MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G473MEY6TR 32-bit ARM Cortex-M4 MCU at 170 MHz with 512 KB Flash, 128 KB SRAM, 42x12b ADC, 7x12b DAC.
