The four DAC outputs are unusual in a 32-LQFP package — they let you generate analog setpoints or offset voltages without external DAC chips. The ADC can sample multiple channels in sequence, useful for reading three-phase currents and a DC-link voltage in a motor drive. Combined with the internal oscillator, the part can run a control loop with no external crystal, saving two pins and a few cents on the BOM. ## Connectivity and peripherals for industrial buses The STM32G431KBT6 includes a CANbus interface, which is a must for industrial automation and automotive-adjacent applications. ## Lifecycle status — active, no obsolescence concern The base product number STM32G431 covers multiple Flash and pin-count variants, which gives some flexibility if you later need to scale up or down within the same family.","metaTitle":"STM32G431KBT6 ARM Cortex-M4F MCU, 170 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32G431KBT6 32-bit MCU with ARM Cortex-M4F at 170 MHz, 128 KB Flash, 32 KB SRAM, 11x12b ADC, 4x12b DAC, CANbus, in 32-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":"26","Core Processor":"ARM® Cortex®-M4F","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 11x12b; 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":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8800","priceTiers":[{"qty":1,"price":"$6.88000","currency":"USD"},{"qty":10,"price":"$6.21300","currency":"USD"},{"qty":25,"price":"$5.92360","currency":"USD"},{"qty":80,"price":"$5.14350","currency":"USD"},{"qty":250,"price":"$4.91232","currency":"USD"},{"qty":500,"price":"$4.47886","currency":"USD"},{"qty":1000,"price":"$3.94035","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3e40d128049007c9b28385042f93f0dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G431KBT6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32G431KBT6 have CANbus?","answer":"Yes, the connectivity list includes CANbus along with I²C, IrDA, LINbus, SPI, and UART/USART."},{"question":"What is the difference between STM32G431KBT6 and STM32G431CBT6?","answer":"The difference is pin count and I/O: the KBT6 comes in a 32-LQFP with 26 I/O, while the CBT6 is a 48-pin LQFP variant with more I/O.
