MICROCHIP ATA6563-GBQW1

The ATA6562/3 is a high-speed CAN 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 5 Mbps) 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 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 (ATA6563) Three operating modes together with the dedicated fail-safe features make the ATA6562/3 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 ATA6562/3 is a stand-alone dual high-speed CAN transceiver compliant with the ISO 11898-2, ISO 11898-2: 2016, ISO 11898-5 and SAE J2962-2 CAN standards. It provides a very low current consumption in Standby mode and wake-up capability via the CAN bus. There are two versions available, only differing in the function of pin 5:

• ATA6562: The pin 5 is the control input for Silent mode NSIL, allowing the ATA6562 to only receive data but not send data via the bus. The output driver stage is disabled. The VIO line and the VCC line are internally connected, this sets the signal levels of the TXD, RXD, STBY, and NSIL pins to levels compatible with 5V microcontrollers.
• ATA6563: The pin 5 is the VIO pin and should be connected to the microcontroller supply voltage. This allows direct interfacing to microcontrollers with supply voltages down to 3V and adjusts the signal levels of the TXD, RXD, and STBY pins to the I/O levels of the microcontroller. The I/O ports are supplied by the VIO pin.
