The CAN wiki pages
This page collection is intended to provide shared information about aspects of using the CAN network. CAN (Controller Area Network) is a serial bus system, developed to be used in cars to exchange information between different electronic components. Now it is used in nearly all application fields, Industrial, medical, white goods, or pedelecs. CAN was developed by BOSCH. The BOSCH CAN 2.0 B Specification can be downloaded at Bosch or CiA. But now the CAN protocol is standardized by the ISO. The ISO 11898 document is the reference for all CAN implementations.
- Part 1 specifies the data link layer (DLL) and physical signalling of the controller area network (CAN) protocol
- Part 2 specifies the high-speed (non fault-tolerant) physical layer (transmission rates of up to 1 Mbit/s)
- Part 3 describes the low-speed fault-tolerant physical layer at transmission rates above 40 kBit/s up to 125 kBit/s.
- Part 4 specifies the time-triggered communication (TTCAN) protocol which supports distributed real-time control and multiplexing for use within road vehicles
- Part 5 - High-speed medium access unit with low-power mode - defines the power modes of the high-speed medium access unit (MAU)
- Part 6 - High-speed medium access unit with selective wake-up functionality
CAN FD protocol extension will be part of 11898-1, published with the next release. There is also rumor that the ISO TF CAN is going to merge the ISO 11898-2, -5, -6 high-speed transceiver standards.
