The FPU handles trigonometric and division operations without software emulation, so the same clock delivers more useful throughput per MHz than a Cortex-M3 at a comparable frequency. The 128 KB SRAM is sized to hold a full set of motor phase currents, rotor position, and a PID state vector without spilling to Flash. ## Analog integration: 42 ADC channels, 7 DAC channels The 42x12-bit ADC channels cover three separate SAR ADCs that can sample simultaneously, which is the typical requirement for three-phase motor current sensing plus a DC-link voltage measurement in one conversion window. The 7x12-bit DAC channels can generate analog references or offset trim voltages for external comparators and op-amps. Combined with the built-in comparators and operational amplifiers in the STM32G4 peripheral set, this part can close a current-control loop entirely on-chip. ## Connectivity and peripheral set for system integration The 107 general-purpose I/O pins in the 128-LQFP package leave room for parallel sensor arrays, external memory buses, or a human-machine interface. Brown-out detection, power-on reset, DMA, and a watchdog timer are built in, reducing external supervisor IC count. ## Lifecycle and sourcing posture No last-time-buy risk is present today.","metaTitle":"STM32G474QCT6 ARM Cortex-M4F MCU, 170 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32G474QCT6 32-bit MCU with ARM Cortex-M4F at 170 MHz, 256 KB Flash, 128 KB SRAM, 42x12-bit ADC, 7x12-bit DAC, 128-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"107","Core Processor":"ARM® Cortex®-M4F","Package / Case":"128-LQFP","Product Status":"Active","Data Converters":"A/D 42x12b; D/A 7x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G474","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"128-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4962","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87dd293d9fefbfea3016ee54e7d8f49f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the core processor of STM32G474QCT6?","answer":"The core processor is an ARM Cortex-M4F with a single-precision floating-point unit, running at 170 MHz.
