The CD1040A is the interface between the Controller Area Network (CAN) protocol controller and the physical bus.It is primarily intended for high speed applications, up to1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller.
The CD1040A is the next step up from the CD1050A high speed CAN transceiver. Being pin compatible and offering the same excellent EMC performance, the CD1040A also features:
• An ideal passive behaviour when supply voltage is off
• A very low-current standby mode with remote wake-up capability via the bus.
This makes the CD1040A an excellent choice in nodes which can be in power-down or standby mode in partially powered networks.
