CAN is a serial bus system that connects microcontrollers, sensor and actuators for real-time control applications.
The usage 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 inside 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 standards
of CAN networks have been developed over the last years. The TLE6251-2G is a High Speed CAN transceiver
with dedicated Wake - Up functions. High Speed CAN Transceivers with Wake - Up functions are defined by the
international standard ISO 11898-5.
