DS50002672C - 2
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)
