The part integrates 23 analog-to-digital converter channels at 12-bit resolution and four 12-bit DAC outputs, which can reduce external converter count in mixed-signal control loops like PFC stages, inverter current sensing, or multi-axis servo drives. Combined with the PWM timer peripherals and the CANbus interface, it fits naturally into industrial drives and automotive auxiliary systems where a single chip handles both the control math and the analog front-end. ## Package, pinout, and power rails Housed in a 64-LQFP package with a 10x10 mm body, the STM32G431RBT6 brings out 52 general-purpose I/O pins.","metaTitle":"STM32G431RBT6 STM32G4 MCU, ARM Cortex-M4F, 170 MHz","metaDescription":"STM32G431RBT6 32-bit MCU with ARM Cortex-M4F core at 170 MHz, 128 KB Flash, 32K x 8 RAM, 23x12b ADC, 4x12b DAC, 52 I/O, 64-LQFP.","metaKeywords":null},"attributes":{"series":"STM32G4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"170MHz","Series":"STM32G4","Package":"Tray","RAM Size":"32K 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, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M4F","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 23x12b; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G431","Program Memory Size":"128KB (128K 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":"$6.5900","priceTiers":[{"qty":1,"price":"$6.59000","currency":"USD"},{"qty":10,"price":"$5.95600","currency":"USD"},{"qty":25,"price":"$5.67840","currency":"USD"},{"qty":160,"price":"$4.93063","currency":"USD"},{"qty":320,"price":"$4.70903","currency":"USD"},{"qty":480,"price":"$4.29354","currency":"USD"},{"qty":960,"price":"$3.73953","currency":"USD"},{"qty":2400,"price":"$3.60103","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3e40d128049007c9b28385042f93f0dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G431RBT6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32G431RBT6?","answer":"The STM32G431RBT6 runs at 170 MHz from its ARM Cortex-M4F core."},{"question":"What is the difference between STM32G431RBT6 and STM32G431RBT7?","answer":"The evidence does not specify differences between these two order codes.
