Device Overview


The ATA6570 is a CAN Partial Networking (PN) transceiver that interfaces a Controller Area Network (CAN) protocol controller and the physical two wire CAN bus designed for high speed CAN applications in the automotive environment. It provides local and enhanced remote wake-up capabilities. The Microchip ATA6570 has a very low power consumption in Standby and Sleep Mode. Beside local wake-up via WAKE and remote wake-up pattern according to ISO 11898-2: 2016 and also additionally supports ISO11898-2: 2016 compliant CAN partial networking. A CAN frame decoder evaluates the bus traffic and checks for a matching frame, that has being configured into registers via the SPI. The device is able to keep the complete ECU in a low power mode even when bus traffic is present until a valid wake-up frame is received. It also features a watchdog, a Serial Peripheral Interface (SPI) and automatic adjustment of the I/O levels to the I/O level of the connected microcontroller via the VIO pin. The Microchip ATA6570 is a CAN-FD device and can be easily configured via the SPI as Non-FD (meaning only for Classical CAN), CAN FD silent, CAN FD passive or as CAN FD active device, in order to fulfill the corresponding application requirements.

To purchase the ATA6570 or obtain additional information, please contact any Microchip sales representative or authorized worldwide distributor.
