Working Principles

The UJA1065TW/3V3/C/T is a high-speed CAN transceiver designed for automotive communication. It operates based on the Controller Area Network (CAN) protocol, which allows electronic control units (ECUs) in vehicles to communicate with each other.

The transceiver receives data from the transmitting ECU through the TXD pin and transmits it over the CAN bus using the CANH and CANL pins. The receiving ECU retrieves the data from the bus through the RXD pin. The STB pin controls the standby mode of the transceiver, reducing power consumption when not in use.

The UJA1065TW/3V3/C/T also includes a LIN bus interface, enabling communication with LIN bus-compatible devices. This integration enhances the versatility of the IC for various automotive applications.
