Product details

For production planning, the base product number STM32L471 is shared across density and package variants, so a migration to a larger BGA or a smaller flash option stays within the same family footprint.

Peripheral set — CAN, QSPI, SAI, and 19-channel 12-bit ADC

Connectivity includes CANbus, I²C, SPI, UART/USART, QSPI, and SAI — enough for a multi-sensor node with a serial Flash and an audio codec on the same die. Brown-out detect and DMA are built in, so the firmware can sleep deep and wake on a threshold.

Frequently asked questions

Can STM32L471QGI6 be programmed with ST-Link V2?

Yes, the STM32L4 series uses the standard SWD (Serial Wire Debug) interface supported by ST-Link V2 and V3.
