Electrical characteristics

USB characteristics

The STM32F042x4/x6 USB interface is fully compliant with the USB specification version
2.0 and is USB-IF certified (for Full-speed device operation).

CAN (controller area network) interface

Refer to

Section 6.3.14: I/O port characteristics

for more details on the input/output alternate

function characteristics (CAN_TX and CAN_RX).
