The STM32L462VET6: The 83 general-purpose I/O lines in a 100-pin LQFP package give you the pin count to keep external GPIO expanders off the BOM when you need parallel displays or multiple encoder interfaces.
Peripheral set — CAN, USB, and external memory expansion
This part includes CANbus (for industrial or automotive gateway nodes), USB (for device or OTG host), and a Quad-SPI interface for attaching external Flash or PSRAM without chewing up GPIO on a parallel bus. The SAI peripheral handles I²S audio codec links, and the MMC/SD interface reads from a microSD card directly.
The base product number is STM32L462, and the part is in the STM32L4 series — a current, well-supported family with ongoing firmware library updates from ST.
Package and temperature — board-fit check
Housed in a 100-LQFP (14x14 mm) surface-mount package, this is a standard QFP footprint with 0.5 mm pitch — no BGA rework required, and visual inspection is straightforward.
