The CAN FD Controller implements a Controller Area Network as specified in the ISO 11898:2015 Part 1, supporting both Classical and Flexible Data Rate CAN frame formats. The CAN FD Controller supports bit rates up to 1 Mbit/s for Classical CAN frame format and up to 10Mbit/s for Flexible Data Rate format.
The Controller Area Network (CAN) is a serial communications protocol which efficiently supports distributed real-time control with a very high level of security. The new Flexible Data Rate frame format introduced in ISO 11898:2015 Part 1 allows higher data rates and larger payloads per frame.
Its domain of application ranges from high speed networks to low cost multiplex wiring. In airborne and automotive industries, electronic control units, sensors, and actuators are connected using CAN.
The CAN FD Controller has been developed to DAL A according to the DO-254. For lower DAL levels reduced documentation sets are available. The core is also available as encrypted source code for DAL D projects or projects not needed DO-254 compliance.
