The STM32L475VGT6: It is built for applications that need both signal-processing throughput — the Cortex-M4 includes a single-cycle multiply-accumulate and FPU — and the low-power modes (multiple stop/sleep states) that stretch battery life in IoT edge nodes, portable medical devices, and industrial sensors. The 1 MB Flash gives room for a full protocol stack plus an OTA update staging region without adding external memory.
The connectivity set is broad: CANbus, EBI/EMI, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, and USB OTG. This reduces the need for external interface ICs in designs that talk to sensors, displays, memory, or a vehicle bus.
Package and I/O
Housed in a 100-pin LQFP (14x14 mm body), the part brings out 82 general-purpose I/O lines. The 100-LQFP footprint is a common mid-density package that balances pin count against board area — suitable for two-layer PCBs with careful routing, or four-layer designs for signal integrity on the high-speed interfaces.
It is ROHS3 compliant.
