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.
