Atmel ATA6661-EK Application Note

APPLICATION NOTE
ATA6661/ATA6662/ATA6662C Development Board
ATA6661/ATA6662
Introduction
®
The development board for the Atmel ATA6661/ATA6662 (ATA6661-EK, ATA6662-EK) is
designed to give designers a quick start with these ICs and for the prototyping and testing
of new designs. The Atmel ATA6661/ATA6662 is a fully integrated LIN transceiver comply-
ing with the LIN 2.x specification. The Atmel ATA6661 and Atmel ATA6662 are pin and
function compatible, but the Atmel ATA6662 has improved EMC behavior.
The IC interfaces between the LIN protocol handler and the physical layer, and is designed
to handle the low-speed data communication in vehicles, for example, in convenience elec-
tronics. Improved slope control on the LIN bus ensures secure data communication up to
20Kbaud with a RC oscillator for the protocol handling. The bus output is capable of with-
standing high voltage and complies with the 42V powernet requirements. Sleep mode
guarantees minimal current consumption.
This document has been developed to give the user an quick start with the development
board of the Atmel ATA6661/ATA6662. For more detailed information about the use of the
Atmel ATA6661/ATA6662 itself, please refer to the corresponding datasheet.
