The 32 KB SRAM holds two or three 12-bit ADC buffer sets plus the control variables; if your application needs a large display frame buffer or a TCP/IP stack, the G431's memory tier may be tight. The 170 MHz Cortex-M4 with FPU and DSP instructions does the heavy math, but the memory map sets the ceiling for what fits. ## 23-ch ADC, 4-ch DAC — analog integration The 23-channel 12-bit ADC and 4-channel 12-bit DAC let this MCU handle multi-phase current sensing and analog set-point generation without external converters. The ADC channels cover three-phase current plus a DC-link voltage sense in a typical motor drive, with channels left over for temperature or position feedback. ## 64-LQFP 10x10 mm — rework and layout The 52 I/O lines fan out to two or four inner layers; a two-layer board routes it with careful signal assignment. That means ST continues to manufacture it, accept new orders, and support it with datasheets, errata, and application notes.","metaTitle":"STM32G431R8T6 STM32G4 ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G431R8T6 32-bit ARM Cortex-M4 MCU at 170 MHz, 64 KB Flash, 32 KB SRAM, 23-ch ADC, 4-ch 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":"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®-M4","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":"64KB (64K 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":"$4.2054","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/88082d99dc99f94106e4989f731259ef.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32G431R8T6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32G431R8T6 and STM32G431C6T6?","answer":"The difference is in package and memory.
