The ADC bank covers three-phase motor currents plus a DC-link voltage sense on a single chip; the DAC channels can drive setpoints for multiple power-stage references. The brown-out detect and POR blocks eliminate the need for a separate supervisor IC in most designs. ## Connectivity and peripheral set for mixed-signal control The I²S peripheral supports audio-class serial data, though the primary application is synchronous motor feedback rather than audio. The 125 °C upper limit covers under-hood electronics, engine-bay sensor interfaces, and outdoor telecom equipment. ## Package and thermal management Without those vias, the junction temperature rises faster than the datasheet thermal resistance suggests at continuous 170 MHz operation with all peripherals active. The surface-mount footprint is compatible with standard reflow profiles; MSL rating should be confirmed on the reel label for bake requirements before reflow. ## Lifecycle and supply position This is a current-generation part in the STM32G4 family, not a legacy or phase-out line. For dual-sourcing resilience, the STM32G474CEU3 is a pin-compatible sibling with the same package and pinout, differing only in Flash density (512 KB versus 256 KB). The CEU3 variant is a drop-in replacement if the firmware fits the larger memory map, though the BOM cost delta is small enough that the CEU3 is often preferred for headroom. No second-source from another manufacturer exists — this is an ST-proprietary architecture.","metaTitle":"STM32G474CCU3 ARM Cortex-M4F MCU, 170 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32G474CCU3 32-bit MCU with 170 MHz Cortex-M4F, 256 KB Flash, 128 KB RAM, 42 I/O, -40 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":"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":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.9195","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/320421a839b0221632b77f7510de8363.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32G474CCU3 and STM32G474CEU3?","answer":"The STM32G474CEU3 is the pin-compatible higher-density sibling with 512 KB Flash instead of 256 KB.
