Specifications of CY8C5246AXI-038

• Lead Free Status / RoHS Status: Compliant

conforms to the ISO-11898-1 standard. The CAN protocol was
originally designed for automotive applications with a focus on a
high level of fault detection. This ensures high communication
reliability at a low cost. Because of its success in automotive
applications, CAN is used as a standard communication protocol
for motion oriented machine control networks (CANOpen) and
