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 brown-out detect and POR peripherals add supply-rail supervision without an external supervisor IC. 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.
