The Microchip ATA6563 is a high-speed CAN FD transceiver that provides an interface between a controller area network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 5Mbit/s) CAN 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 electrostatic discharge (ESD) performance, 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

Two operating modes (Standby and Normal Mode) together with the dedicated fail-safe features make the Atmel. ATA6563 an excellent choice for all types of high- speed CAN networks, especially in nodes requiring low-power mode with wake-up capability via the CAN bus.

The ATA6563 is automotive Grade 0 qualified for an ambient temperature range from -40° to 150°C.

To purchase the ATA6563 or obtain additional information, please contact any Microchip sales representative or authorized worldwide distributor.
