●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 anidentical version, the only difference is that the TXD-dominantTime-out function is disabled so the device is able to send a static low signal tothe 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, inconvenience 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.
