Description
The Atmel ATA6663 is a fully integrated LIN transceiver complying with the LIN
specification 2.0, 2.1 and SAEJ2602-2. The Atmel ATA6664 is an identical version, the
only difference is that the TXD-dominant Time-out function is disabled so the device is able
to send a static low signal to the LIN bus. It interfaces the LIN protocol handler and the
physical layer. The device is designed to handle the low-speed data communication in
vehicles, for example, in convenience electronics. Improved slope control at the LIN driver
ensures secure data communication up to 20Kbaud. Sleep Mode guarantees minimal cur-
rent consumption even in the case of a floating bus line or a short circuit on the LIN bus to
GND. The ATA6663/ATA6664 feature advanced EMI and ESD performance.
