Typical 5V Application Circuit with One Wire Control

delivered from the LIN transceiver ATA6625 device. The application can be directly connected
to vehicle's wiring harness. In this case, the pin PB4 (PWRON) is directly connected to VS and
the Atmel
after the software in the Flash asserts the EN pin on ATA6625 to HIGH. The system can be
completely switched on or off with a command over the one wire bus. This application is used
when the external host microcontroller must be separated over a distance from the Atmel
ATA5830 such as systems having remote antennas integrated into window glass. In these sit-
uations, the Atmel ATA5830 can work autonomously and communicate to external host
microcontroller on a 1 wire bus.
The Application software within the 6KB Flash, together with 24KB ROM firmware, is used for
the control of the Atmel ATA5830 and Atmel ATA6625. A simplified LIN compliant physical
layer can be used for one wire communication. The Atmel ATA5830 does not natively support
one wire commands. However, through the use of application Flash software one wire com-
munication can be achieved.
