Overview
The TJA1040T/N1,118, produced by NXP USA Inc., is a high-speed CAN (Controller Area Network) transceiver designed to interface between the CAN protocol controller and the physical bus. It is primarily intended for high-speed applications, up to 1 MBaud, particularly in passenger cars. This device is known for its low current consumption and remote wake-up capability, making it an excellent choice for nodes that can be in power-down or standby mode in partially powered networks.
