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.
