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 improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD)oer
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 via the SPI as Non-FD (meaning classicalcongured
CAN 2.0), CAN FD silent, CAN FD passive or as CAN FD active device in order to the correspondingfulll
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 Microcontrollerso.

management with local and remote wake-up support makes it possible to achieve very low current
consumption in Standby and Sleep mode, even when the internal VIO and VCC supplies are switched
o. Diagnostic and protection functions, including bus line short-circuit detection and battery connection
detection, are also part of the ATA6571's features.
Various operating modes together with the dedicated fail-safe features make the ATA657X an excellent choice
for all types of high-speed CAN networks, especially in nodes requiring low-power mode with local wake-up
capability or via the CAN bus. With the INH output, they have the capability to power down the complete CAN
node.
The ATA657X devices are available in a SOIC14 package as well as in a VDFN14 package, for space-saving
applications. The ATAB657XA development board supports only SOIC14 packages. However, an adaptor board
can be plugged in using the adaptor board-header, if a device in a VDFN package is used (the adaptor board is
not within the scope of supply and services of this demo kit/board).

Development Board Features
The development board for the ATA657X ICs supports the following features:
All components necessary to put the ATA6570/ATA6574 or ATA6571 into operation are included
Placeholders for some optional components for extended functions
All pins are easily accessible
Switching into Normal, Standby or Sleep mode via two jumpers (ATA6571)
Push button included for creating a local wake-up after entering Sleep mode
LEDs for operation indication
Ground coulter clip for easy probe connection while measuring with oscilloscope
Connectors for direct plug-in with the C21-XPRO Xplained board (only ATA6570/ATA6574 with SPI)

1. Hardware Descripon
The development board for the ATA657X is shipped with all the components needed to start
developing a CAN node immediately. However, commands, data and status information are
transferred to and from the ATA6570/ATA6574 via SPI. This is how the ATA6570/ATA6574 can be
congured and operated.
Microchip an Xplained Pro board (ATSAMC21-XPRO Xplained board), which can be used tooers
interface with the ATA657X GUI to operate and control the ATA6570/ATA6574. This Xplained Pro
board must be ordered separately, as the ATAB657XA board comes as a stand-alone board. The
ATA657X GUI can be downloaded directly from Microchip’s web site: .

After correctly connecting an external 12V DC power supply (Power Header VBAT) to the power
connector of the ATAB657X A board and connecting the Xplained Pro interface board to the PC via
the USB cable, the kit is ready to use. To start working with the kit, execute the .ata65xx.exe
The ATA6570/ATA6574 IC starts in Standby mode, INH is active (if jumper J4 is set the LED D3 is ON)
and the window watchdog is switched for the ATA6570/ATA6574. A quick check to determine ifo
everything is working properly can be done by executing the following:
CAN Communication Check:
Click the button in the sectionNormal Mode Operating mode
Click the button in the sectionNormal Mode CAN transceiver
Set “TXD Pulsed”
Choose 250kHz as “Frequency” and press the button. A 250kHz signal should be visible onSet
the CANH and CANL pins, when you put oscilloscope probes on those pins.
