The STM32L475RCT3: That memory partition leaves room for a real-time OS, a moderate application stack, and data buffers without external memory on most industrial sensor or IoT gateway designs.
Peripheral set and mixed-signal front-end
Connectivity includes USB OTG, CANbus, multiple SPI and I²C interfaces, QSPI for external flash, and SAI for audio streaming. The 16-channel 12-bit ADC and dual 12-bit DAC let the chip handle sensor acquisition and analog output without an external converter. 51 general-purpose I/O lines are available in the 64-LQFP package (10x10 mm, 0.5 mm pitch). The LQFP footprint is a standard layout — no fine-pitch rework required, and the exposed paddle aids thermal transfer to the PCB copper plane.
