The 42 I/O count leaves 6 pins tied to supply and ground — enough for a sensor-rich motor drive or a digital power converter with a handful of Hall-effect inputs and gate-drive PWM outputs.","metaTitle":"STM32G474CBU6 32-bit MCU, ARM Cortex-M4F 170 MHz","metaDescription":"STM32G474CBU6 32-bit ARM Cortex-M4F MCU at 170 MHz with 128 KB Flash, 128K x 8 RAM, 21x12b ADC, 7x12b DAC.","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":"42","Core Processor":"ARM® Cortex®-M4F","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 21x12b; D/A 7x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G474","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0312","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/320421a839b0221632b77f7510de8363.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does STM32G474CBU6 compare to STM32G474RCT6?","answer":"The STM32G474RCT6 is a pin-compatible higher-density sibling in the same family: it offers 256 KB Flash and 40 K x 8 RAM versus the 128 KB Flash and 128K x 8 RAM on the CBU6, in a larger 64-pin LQFP package.
