Connectivity includes CANbus, USB, QSPI, SAI, I2C, SPI, and multiple UART/USART interfaces, covering fieldbus, external memory expansion, and audio codec links without glue logic. The 64-LQFP (10x10 mm) package with 52 accessible I/O fits 2-layer PCB layouts and hand-assembly or reflow processes.","metaTitle":"STM32G473RET6 STM32G4 ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G473RET6 32-bit ARM Cortex-M4 MCU at 170 MHz with 512 KB Flash, 128 KB SRAM, 26x12b ADC, 4x12b DAC, 64-LQFP.","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":"52","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 26x12b; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G473","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3622b0c8d7ddc16064f775c2c4cc5029.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can STM32G473RET6 be used in place of STM32G474RET6?","answer":"The STM32G474RET6 is a close sibling in the same STM32G4 family, typically offering additional HRTIM (high-resolution timer) features for advanced power conversion. The STM32G473RET6 lacks that specific timer peripheral. Pin compatibility and memory sizing should be verified against the respective datasheets before substitution."},{"question":"What development board supports STM32G473RET6?","answer":"STMicroelectronics offers the NUCLEO-G473RE development board, which is built around the STM32G473RE (the same core with 512 KB Flash in an LQFP-64 package).
