Peripherals and I/O budget
Fifty-four general-purpose I/O lines in a 64-LQFP package give enough pins for a parallel LCD data bus or a bank of opto-coupled inputs alongside the serial interfaces. Connectivity covers I²C, SPI, UART, and LINbus — the LIN interface is useful for automotive sub-bus nodes or industrial sensor networks where a single twisted pair carries both power and data.
