CAN and CAN FD Partial Networking Transceivers

View All Parametrics

For More Efficient and Variable Nodes in CAN Bus Networks

Our CAN Partial Networking (PN) transceivers offer various operating modes and dedicated fail-safe features that make them an excellent choice if you are designing high-speed CAN bus networks where the nodes are always connected to the battery but are only active when required by the application. These operating modes make it possible for a particular node or complete cluster to remain in selective sleep mode without wasting energy, which minimizes overall current consumption when the related tasks are not required. Less overall active current for inactive nodes creates a much more efficient system and adds flexibility to your next design.

These CAN PN transceivers offer very low power consumption in standby and sleep modes and support ISO 11898-2:2016 compliant CAN PN by offering a selective wake-up function. A CAN frame decoder evaluates the bus traffic and checks for a matching frame that has been configured into registers via the SPI. A dedicated implementation of the partial networking function has been embedded into our CAN PN transceivers, allowing CAN FD frames to be ignored during sleep/standby mode while waiting for a dedicated valid wake-up frame.

The partial networking feature is a great fit for networks that support both CAN FD and classic CAN communications, allowing classic CAN controllers that do not need to communicate CAN FD messages or are not supporting CAN FD to remain in partial networking mode during CAN FD communication. This is done by ignoring received CAN FD frames without generating bus errors. A window watchdog is also implemented in these CAN PN transceivers.

ATA6574

High-Speed CAN FD Transceiver With a Window Watchdog

The ATA6574 CAN PN transceiver interfaces a CAN protocol controller and the physical two-wire CAN bus. Designed for high-speed CAN in automotive applications, it provides local and enhanced remote wake-up capabilities and features very low power consumption in Standby and Sleep modes. In addition to CAN PN, it supports local wake-up via WAKE and the remote wake-up pattern defined in ISO 11898-2:2024.

Notes:

The ATA6574 has the same functionality as the ATA6570. It is recommended for European OEMs, as it has the 5 Mbps FTZ EMC certification.

All necessary worldwide EMC certifications and conformance reports have been obtained, and the documentation is available.

ATA6570

The ATA6570 is a high-speed CAN FD transceiver with a window watchdog and a CAN FD-passive implementation of the partial networking function. This dedicated feature allows the ATA6570 to be used in classic CAN, CAN FD and mixed CAN networks, and it reduces current consumption by only activating those nodes that are required at the time.
