It sits in the STM32G4 series, which targets digital power conversion, motor control, and industrial sensing — applications where the combination of a fast math-capable core and dense analog peripherals reduces external component count. ## Analog peripheral density — 23 ADC channels, 4 DAC outputs This part carries 23 external analog-to-digital converter channels at 12-bit resolution and four 12-bit digital-to-analog converters. For a three-phase motor drive with current sensing on each phase plus DC-link voltage and temperature feedback, the ADC channel count covers the bill without an external mux. The four DAC outputs can generate analog reference voltages or feed a set-point directly to an external amplifier — useful in programmable power supplies or waveform generation. ## Connectivity and control peripherals Five 16-bit timers with PWM generation and a dedicated PWM timer are standard for the series. The built-in brown-out detect and power-on reset simplify the power-supply supervisory circuit. ## Package and temperature grade for the BOM Housed in a 64-ball UFBGA package measuring 5x5 mm (supplier device package 64-UFBGA), this is a fine-pitch BGA intended for space-constrained PCBs.","metaTitle":"STM32G431RBI6 STM32G4 ARM Cortex-M4F MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G431RBI6 32-bit MCU with ARM Cortex-M4F core at 170 MHz, 128 KB Flash, 32 KB SRAM, 23x12-bit ADC, 4x12-bit DAC, CANbus, -40°C to 85°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":"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-UFBGA","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-UFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5585","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/88082d99dc99f94106e4989f731259ef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32G431RBI6?","answer":"The STM32G431RBI6 is rated for a 170 MHz core clock.
