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. It is 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 been configured in the registers via 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 capable device. Wakeup via Wake-up frames can be configured to be either CAN-FD tolerant (CAN-FD frames are ignored) or to increase an error counter when receiving FD frames.Read more
