For a three-phase motor current-sense design you can sample all three shunt resistors plus the DC-link voltage and still have channels left for thermistor and encoder inputs. The seven DACs cover offset trim or reference generation without external op-amp stages. Brown-out detect, POR, and a true random number generator are on the peripheral list, so the watchdog and TRNG share the die rather than needing external supervisor ICs. At the low end, 1.71 V is close to the dropout of a 1.8 V rail, so a battery-backed design can run the MCU until the cell is nearly flat. ## Connectivity and debug access CANbus, I²C, SPI, QSPI, SAI, UART/USART, IrDA, LINbus, and USB are all present. The QSPI interface lets you memory-map an external NOR Flash for code shadowing or data logging without chewing up GPIO for a parallel bus. SWD debug stays alive even with the watchdog armed — useful when the firmware is still unstable and you need to break into a hung loop without a hardware reset. ## Lifecycle and sourcing posture STMicroelectronics lists the STM32G473CEU3 as Active.","metaTitle":"STM32G473CEU3 ARM Cortex-M4 MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G473CEU3 32-bit ARM Cortex-M4 MCU at 170 MHz with 512 KB Flash, 128 KB SRAM, 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":"Bulk","RAM Size":"128K x 8","Core Size":"32-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, TRNG, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, QSPI, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"42","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 21x12b SAR; D/A 7x12b","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.6015","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3622b0c8d7ddc16064f775c2c4cc5029.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum operating frequency of STM32G473CEU3?","answer":"The STM32G473CEU3 runs at 170 MHz from the ARM Cortex-M4 core.
