For a three-phase motor controller, that means one ADC channel per phase current plus room for DC-link voltage and temperature sensing, with DACs available for analog setpoint generation or offset trimming. The 12-bit resolution is adequate for 0.1% accuracy in most industrial feedback loops; if higher precision is needed, the external reference pin lets you improve the ADC's effective resolution beyond the internal Vref. The exposed pad also improves EMI by providing a low-inductance ground return for the high-speed I/O. For dual-sourcing resilience, the STM32G491 line includes multiple density and package variants that share the same peripheral set and pinout across the UFQFPN-48 footprint — a BOM can be qualified across the family without a board respin.","metaTitle":"STM32G491CCU6 ARM Cortex-M4F MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G491CCU6 32-bit MCU with ARM Cortex-M4F core at 170 MHz, 512 KB Flash, 112 KB SRAM, 42 I/O, industrial temp -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":"112K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, IRTIM, LINbus, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"42","Core Processor":"ARM® Cortex®-M4F","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 19x12b; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G491","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.1900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/475873daeb61e31a5487d47a07b785e4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can STM32G491CCU6 be used for motor control?","answer":"Yes. The 170 MHz Cortex-M4F with FPU, 19-channel 12-bit ADC, multiple timers with PWM generation, and CANbus/SPI connectivity are well suited for field-oriented control of brushless DC or permanent-magnet synchronous motors. The 112 KB SRAM provides enough headroom for the control loop state variables and communication buffers."},{"question":"What development board works with STM32G491CCU6?","answer":"STMicroelectronics offers the NUCLEO-G491RE and STM32G491C-DISCO development boards for the STM32G491 series.
