Product details

The STM32G491VET6: 170 MHz ARM Cortex-M4F core with 512 KB Flash and 112K x 8 SRAM.

86 I/Os and a rich peripheral set

With 86 I/Os brought out to the 100-LQFP package, this part can handle substantial board-level connectivity. 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.

Frequently asked questions

What is the closest pin-compatible alternative to STM32G491VET6 in the STM32G4 family?

Within the STM32G4 series, the STM32G491VET6 shares the 100-LQFP footprint with other density variants. The key difference is Flash and RAM sizing — a lower-density sibling (e.g., STM32G491RET6 with 512 KB Flash) may be pin-compatible but check the specific memory map and peripheral set against your firmware requirements.
