Combined with the CANbus, USB, and QSPI interfaces, this part fits into fieldbus-connected actuator nodes or sensor hubs that need local signal conditioning. The 48-UFQFN package with exposed pad (7x7 mm) keeps the board area small, but the thermal pad needs a proper via stitch to the ground plane to get the junction temperature under control above 85°C ambient. The 125°C ceiling means the processor can sit next to a power stage without a heatsink as long as the total dissipation stays within the package limits.","metaTitle":"STM32G491CCU3TR 32-bit ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G491CCU3TR ARM Cortex-M4 MCU at 170 MHz, 256 KB Flash, 112 KB SRAM, -40°C to 125°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":"Tape & Reel (TR)","RAM Size":"112K x 8","Core Size":"32-Bit","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, QSPI, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"42","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 19x12b SAR; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9651","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/402d6026ee008535da950a87d7b9c5c0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32G491CCU3TR and STM32G491CCU6?","answer":"The difference is the shipping medium: the 'TR' suffix indicates Tape & Reel packaging, while the 'U6' variant typically ships in tray or tube.
