The 12-bit resolution on both converters is adequate for most industrial control loops; if you need higher precision, an external ADC is the next step. The data converter count alone tells you this is a mixed-signal part, not a general-purpose controller. ## Lifecycle and sourcing posture It is a current-production part from STMicroelectronics, available through independent distribution.","metaTitle":"STM32G473QCT6 ARM Cortex-M4 MCU, 170 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32G473QCT6 32-bit MCU with 170 MHz Cortex-M4 core, 256 KB Flash, 128 KB SRAM, 42x12-bit ADC, 7x12-bit DAC, CANbus, USB.","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, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"107","Core Processor":"ARM® Cortex®-M4","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":"STM32G473","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":"$8.2571","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3622b0c8d7ddc16064f775c2c4cc5029.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STM32G473QCT6 compatible with STM32G474QCT6?","answer":"Yes, the STM32G473QCT6 and STM32G474QCT6 are pin-compatible in the same 128-LQFP package.
