1. Introduction
The development board for the Atmel
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 inte-
grated LIN transceiver complying with the LIN 2.0 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 electronics. 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 withstanding 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 develop-
ment 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.
