CAN is a serial bus system that connects microcontrollers, sensors and actuators for real-time control applications.
The use of the Control Area Network (abbreviated CAN) within road vehicles is described by the international
standard ISO 11898. According to the 7-layer OSI reference model, the physical layer of a CAN bus system
specifies the data transmission from one CAN node to all other available CAN nodes within the network. The
physical layer specification of a CAN bus system includes all electrical and mechanical specifications of a CAN
network. The CAN transceiver is part of the physical layer specification. Several different physical layer definitions
of CAN networks have been developed in recent years. The TLE7250G is a High Speed CAN transceiver without
a dedicated wake-up function. High Speed CAN transceivers without a wake-up function are defined by the
international standard ISO 11898-2.
