Atmel Microcontroller with LIN Transceiver ATA6602 User Manual

Features, Benefits, Automotive & control

background image

The ATA6602/ATA6603 are single-package dual-chip circuits for LIN-bus slave and master node applica-
tions. They support highly integrated solutions for in-vehicle LIN networks. The LIN-system-basis-chip
(LIN-SBC) consists of a LIN transceiver, which complies with the LIN specification; a voltage regulator; and
a window watchdog. The second chip used in the ATA6602 and ATA6603 is from Atmel

®

’s series of AVR

®

8-bit microcontrollers with advanced RISC architecture. An ATmega88 microcontroller is used in the
ATA6602, while an ATmega168 is used in the ATA6603. The LIN-SBC and the microcontroller are mounted
in a small QFN48 package. This dual-chip combination makes it possible to develop inexpensive, simple,
yet powerful master and slave nodes for use in LIN-bus systems.
