Functional Description

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 definitions

of a CAN network have been developed over the last years. The TLE8250G is a High Speed CAN transceiver

without any dedicated Wake-Up function. High Speed CAN Transceivers without Wake-Up function are defined

by the international standard ISO 11898-2.
