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 bus ensures secure data communication at up to 20Kbaud with an RC oscillator for protocol handling. Sleep Mode guarantees minimal current 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.

ATA6663/ATA6664主要特性:

• Operating Range from 5V to 27V

• Baud Rate up to 20Kbaud
