The single-cycle multiply-and-accumulate and FPU handle fast math for motor field-oriented control or digital power conversion without a separate DSP. ## Analog front end — 20 ADC channels, 7 DAC outputs With 20 x 12-bit ADC inputs and 7 x 12-bit DAC outputs, this part fits applications requiring simultaneous sampling of multiple analog signals — think three-phase motor current sensing plus position feedback, or multi-channel power-supply telemetry. The 12-bit resolution is typical for industrial sensor interfaces where 10- or 12-bit is the baseline. The DAC count is notably high for this package class, reducing the need for external converters in multi-output control systems. ## Industrial temperature grade and connectivity Connectivity includes CANbus, I²C, SPI, QSPI, UART/USART, IrDA, and LINbus — enough interface variety for sensor hubs, gateway nodes, or distributed control networks. The 38 I/O in a 48-LQFP package (7 mm x 7 mm) provide a compact footprint while leaving room for peripheral routing.","metaTitle":"STM32G474CET6 ARM Cortex-M4F MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G474CET6 32-bit MCU: 170 MHz ARM Cortex-M4F, 512 KB Flash, 128 KB RAM, 20x12-bit ADC, 7x12-bit DAC, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32G4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"170MHz","Series":"STM32G4","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, QSPI, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"38","Core Processor":"ARM® Cortex®-M4F","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 20x12b; D/A 7x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G474","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.7200","priceTiers":[{"qty":1,"price":"$9.72000","currency":"USD"},{"qty":10,"price":"$8.78500","currency":"USD"},{"qty":25,"price":"$8.37640","currency":"USD"},{"qty":80,"price":"$7.27313","currency":"USD"},{"qty":230,"price":"$6.94630","currency":"USD"},{"qty":440,"price":"$6.33339","currency":"USD"},{"qty":1500,"price":"$5.51617","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/320421a839b0221632b77f7510de8363.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G474CET6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum operating frequency of STM32G474CET6?","answer":"The core runs at 170 MHz, which is the rated speed for this ARM Cortex-M4F device.
