Introduction
The development board for the Atmel
®
ATA6663/ATA6664 (Atmel ATA6663-EK, ATA6664-
EK) is designed to give users a quick start using these ICs and prototyping and testing new
designs. The Atmel ATA6663/ATA6664 is a fully integrated LIN transceiver complying with
the LIN 2.0, 2.1 specification and SAEJ2602-2. The devices are nearly identical, the only
difference is that the TXD dominant timeout-timer is disabled at the Atmel ATA6664 so this
device is able to send a static low signal on the LIN bus. The Atmel ATA6663 is the succes-
sor IC of the Atmel ATA6662 with an enhanced EMC performance and improved wake-up
behavior resulting in a very low sleep mode current consumption even in the case of a
floating bus or a short-circuit between the bus line and GND.
The ICs are the interface between the LIN protocol handler and the physical layer and is
designed to handle the low-speed data communication in vehicles for example in conve-
nience electronics. Improved slope control on the LIN bus ensures secure data
communication of up to 20kBaud.
This document has been created as a quick start guide for using the development board of
the Atmel ATA6663/ATA6664. Please refer to the corresponding datasheet for more
detailed information about the Atmel ATA6663/ATA6664 itself.
