This function is called ‘FD-passive’ and is the ability to ignore CANFD frames while waiting for a valid wake-up frame in Sleep/Standby mode. This additionalfeature of partial networking is the perfect fit for networks that support both CAN FD andstandard CAN 2.0 communications. It allows normal CAN controllers that do not need tocommunicate CAN FD messages to remain in partial networking Sleep/Standby modeduring CAN FD communication without generating bus errors.\nAdvanced power management regulates the supply throughout the node and supportslocal and remote wake-up functionality. I/O levels are automatically adjusted to the I/Olevels of the controller, allowing the TJA1145 to interface directly with 3.3 V to 5 Vmicrocontrollers. An SPI interface is provided for transceiver control and for retrievingstatus information. Bus connections are truly floating when power is off.\nThe TJA1145 implements the CAN physical layer as defined in the current ISO11898 standards(ISO11898-2:2003, ISO11898-5:2007 and ISO11898-6:2013) and the pending updated versionof ISO 11898-2:2016). Pending the release ISO11898-2:2016 including CAN FD andSAE-J2284-4, additional timing parameters defining loop delay symmetry are included.This implementation enables reliable communication in the CAN FD fast phase at datarates up to 2 Mbit/s.\nThese features make the TJA1145 the ideal choice for high-speed CAN networkscontaining nodes that are always connected to the battery supply line but, in order tominimize current consumption, are only active when required by the application.\n
