The included ATA6624 provides the following features:
The combination of the features included in ATA6612 and ATA6613 make it possible to
develop simple, but powerful and cheap slave nodes in LIN bus systems.
The ICs are designed to handle the low-speed data communication in vehicles, for example, in
convenience electronics. Improved slope control at the LIN driver ensures secure data com-
munication up to 20 kBaud. Sleep Mode and Silent Mode included in the LIN SBC guarantee a
very low current consumption.
The ATA6612 and the ATA6613 are completely pin and functional compatible. They differ only
in the size of the flash memory of the integrated microcontroller. Some minor modifications in
the source code when switching between ATA6612 and ATA6613 during the development
phase may be required. For more information concerning this topic, refer to the application
note AVR095: “Migrating between ATmega48, ATmega88 and ATmega168” available at
http://www.atmel.com/dyn/products/app_notes.asp?family_id=607.
As there is a standard AVR microcontroller with all pins available included in the ATA6612 and
ATA6613, the standard toolchain consisting of the AVR Studio
ulator, and in-circuit-emulator can be used for developing and debugging new applications.
Furthermore, ActiveX
program for emulation of the LIN master node. Using the software components and the devel-
opment board, it is very easy and inexpensive to create and test a LIN network.
In the contrast to the standalone AVRs, the internal 8 MHz RC oscillator has been calibrated
at 5V and therefore perfectly fits the output voltage of the integrated voltage regulator.
This document has been developed to provide the user with start-up information about the
ATA6612 and ATA6613’s development board. For more detailed information about the use of
the devices themselves, refer to the corresponding datasheet.
