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. The four DAC outputs can generate analog reference voltages or drive analog actuators directly, saving board space and BOM cost compared to a separate ADC/DAC chip. ## 64-LQFP 10x10 mm — rework and layout The 64-LQFP package with a 10x10 mm body and 0.5 mm pitch is a standard footprint that reflows reliably with a typical lead-free profile. 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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/88082d99dc99f94106e4989f731259ef.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32G431R8T6 and STM32G431C6T6?","answer":"The difference is in package and memory.
