Introducon

The ATAB657XA development board is a hardware platform used to evaluate the ATA6570, ATA6571 and

ATA6574 CAN devices and to enable users to rapidly prototype and test new CAN designs with the ATA657X ICs.

The ATA657X device family includes three high-speed Controller Area Network (CAN) transceivers, which

interface with a CAN protocol controller and the physical two-wire CAN bus designed for high-speed CAN

applications (up to 5Mbit/s) in the automotive environment. Two of the ATA device variants also support

partial networking. All oer improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD)

performance and very low-power consumption in Standby and Sleep modes:

•Besides local wake-up via WAKE and remote wake-up pattern in accordance with ISO 11898-5, the ATA6570/

ATA6574 are fully compliant with the ISO 11898-6 supporting CAN partial networking. The ATA6570/ATA6574

additionally supports a CAN-FD device and can be easily congured via the SPI as Non-FD (meaning classical

CAN 2.0), CAN FD silent, CAN FD passive or as CAN FD active device in order to fulll the corresponding

application requirements. The VIO pin allows the automatic adjustment of the I/O levels to the I/O level of

the connected microcontroller.

•The ATA6571 has ideal passive behavior to the CAN bus when the supply voltage is o. Microcontrollers

with supply voltages from 3V to 5V can be directly interfaced via the VIO pin. Its advanced low-power
