The peripheral list includes CANbus, I²C, SPI, UART/USART, USB, SAI, and LINbus — covering industrial fieldbus, sensor interfaces, and human-machine interaction. ## Analog front-end: 36-channel 12-bit ADC, 4-channel 12-bit DAC The analog subsystem is a standout: 36 multiplexed 12-bit ADC channels and four 12-bit DAC outputs. This suits designs that need simultaneous multi-axis sensing (current, voltage, position) and analog output generation — for example, a servo drive reading three phase currents and commanding an analog torque reference. The base product number STM32G491 identifies the family, so PCN notifications and errata updates are trackable against that root.","metaTitle":"STM32G491VET6 STM32G4 ARM Cortex-M4F MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G491VET6 32-bit MCU with 170 MHz ARM Cortex-M4F core, 512 KB Flash, 112K x 8 RAM, 100-LQFP.
