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.
