The ATA6571 is a standalone high-speed CAN FD transceiver that interfaces a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 5 Mbit/s) CAN FD applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. It offers improved Electromagnetic Compatibility (EMC) and ESD performance and very low power consumption, as well as features such as:
• Ideal passive behavior to the CAN bus when the supply voltage is off
• Direct interfacing to microcontrollers with supply voltages from 3V to 5V
• Advanced low-power management with local and remote wake-up support, available at all times, even when the internal VIO and VCC supplies are switched off
• Protection and diagnostic functions including bus line short-circuit detection and battery connection detection

To purchase the ATA6571 or obtain additional information, please contact any Microchip sales representative or authorized worldwide distributor.
