ATA6612/ATA6613
The development board for the ATA6612 and ATA6613 is shipped with the default jumper set-
tings and all accessories required for immediate use.
The IC mounted on the board is pre-programmed with a firmware in order to test and to under-
stand the basic functions directly on the board. After correctly connecting an external 12V DC
power supply between the terminals “+” and “-”, the LIN SBC is in Pre-normal Mode. A regu-
lated 5V DC voltage, provided by the internal voltage regulator supplying the internal
microcontroller, can be measured at the PVCC jumper. After the power is supplied to the
microcontroller, the microcontroller switches the LIN SBC to Normal Mode by setting the EN
pin to high (ENABLE jumper), and starts to trigger the integrated window watchdog. The sys-
tem is now ready for data transmission via the LIN bus. Signals fed in at the TXD pin are
visible on the LIN bus, and signals fed in on the LIN bus are visible at the RXD pin. In Normal
Mode, the current consumption is approximately 3 mA and the following voltages and signals
can be seen at the corresponding pins.
