Note: All open pins of the SiP can be used for application-specific purposes.
AVR: TXD, RXD, NRES and EN connected for LIN Master. The connection between the LIN-SBC
and the AVR requires the software being programmed correspondingly. PA7 and PA2 are used as
analog inputs. Additional the application supports a 3*3 switch matrix. PA4, 5, 6 are used as PWM
outputs to control the brightness of light emitting diodes. System clock controlled by external crys-
tal.
LIN-SBC: LIN slave application, 1k Master resistance connected via diode to VBAT, local wake up
via pin WAKE; watchdog is enabled.
RF emissions: Best results for RF emissions will be achieved by connecting the blocking capaci-
tors of the microcontroller supply (C1 and C2) between the microcontroller pins and the
GND/PVCC line. See also
