Where it fits — motor drive, digital power, industrial control
The STM32G474RET3: Rated for -40°C to 125°C operation, this part is built for motor drives, power inverters, and outdoor telecom equipment where the ambient temperature climbs. The 52 I/O lines and CANbus, I²C, SPI, UART/USART, QSPI connectivity handle fieldbus gateways and sensor arrays. Internal oscillator and brown-out detect reduce external BOM count for space-constrained boards.
Lifecycle status — EOL hot, sourced to order
The STM32G474RET3 has an EOL hot lifecycle designation. The manufacturer has issued an end-of-life notice. We source and quote it to order against an RFQ.
What the 170 MHz and 512 KB Flash mean for your BOM
At 170 MHz, the Cortex-M4F with single-cycle multiply-accumulate and floating-point unit handles real-time control loops — field-oriented motor control, digital PFC, or LLC resonant converter — without an external DSP. The 512 KB Flash is sized for firmware with multiple control algorithms and communication stacks; 128 KB SRAM leaves headroom for data logging and large lookup tables. The 26 ADC channels let you sample all three phase currents plus DC-link voltage and temperature in one conversion cycle.
