Controller area network (CAN): Teaching an old dog new tricks

摘要

There is a saying that you cannot teach an old dog new tricks. While CAN is 25 years old, it continues to grow and gain new capabilities. It has been adapted into widely varying applications starting with its roots in simple automotive multiplexing to the current automotive networks, transportation, and industrial applications.rnWithin the CAN transceiver world, there have been recent improvements to provide higher data rates and to bolster functional safety and redundancy within CAN networks. New transceivers have been developed, providing these features.
