Development Board Features
The development board for the Atmel
®
ATA6663/ATA6664 supports the following features:
●
Includes all components necessary for Atmel ATA6663/ATA6664 operation
●
All pins are easily accessible
●
Can be used for master or slave operation
●
Wake-up pulse via an on-board switch
Quick Start
The development board for the Atmel ATA6663/ATA6664 is shipped with all components necessary to immediately start the
development of a LIN slave node.
Connecting an external 12V DC power supply between the terminals VBAT and GND puts the IC in fail-safe mode. In this
mode, the INH pin is switched to the VS level which can be used to enable an external voltage regulator (not included on the
board). The LIN pin is in the recessive state.
Please note that the communication is still inactive during fail-safe mode.
To communicate via the LIN bus interface, you have to switch the device into normal mode by applying a high level (for
example 5V) at pin EN.
As RXD is an open-drain output, the required pull-up resistor R2 can be activated by ap5V DC voltage, on the
designated pin on the board.
