The STM32L433RCT6P: The 64-LQFP package with 52 accessible I/O keeps the pin count manageable for a two-layer board while still offering CAN, USB, multiple SPI and I²C interfaces, plus a QSPI for fast external Flash or RAM expansion.
Peripheral set for mixed-signal and connectivity tasks
On the digital side, the connectivity list includes CANbus for industrial networks, USB for device-to-host links, and a Quad-SPI for high-speed external memory. The LCD peripheral can drive a small segment display directly, saving a driver chip in metering or control-panel designs.
