The Atmel® ATA6570 is a standalone high speed CAN 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 and is available in a SO14 package. The Atmel 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 11898-5, ATA6570 additionally supports ISO11898-6 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 and a Serial Peripheral Interface (SPI).
