It comes in a 48-LQFP package with 38 I/O. ## Industrial temperature grade — deployment context The internal oscillator allows boot without an external crystal. ## Analog integration — ADC and DAC count Twenty 12-bit ADC channels and seven 12-bit DAC channels are on-chip. That is a lot of analog I/O for a 48-pin MCU — enough to sample three-phase currents plus a DC-link voltage while generating multiple analog references or setpoints. The peripherals include CANbus, I²C, SPI, QSPI, UART/USART, and IrDA, so it talks to most sensor and actuator buses without external transceivers beyond the physical layer. ## Lifecycle and supply posture This is a current-production part suitable for new designs.","metaTitle":"STM32G474CBT3 ARM Cortex-M4F MCU, 170 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G474CBT3 32-bit MCU with ARM Cortex-M4F at 170 MHz, 128 KB Flash, 128 KB RAM, 20x12-bit ADC, 7x12-bit DAC, -40°C to 125°C.","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":"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":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3998","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/320421a839b0221632b77f7510de8363.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32G474CBT3 and STM32G474CBT6?","answer":"The STM32G474CBT3 and STM32G474CBT6 share the same core, Flash size, RAM, and peripheral set.
