The CAN and LIN Shield Kit hardware consists of the following functional blocks:
■
2-CAN transceiver circuits (TJA1051T and TJA1055T)
■
2-LIN transceiver circuits in slave configuration (TJA1020)
■
Three status indicator LEDs
■
Arduino header
■
12 V input Power Jack and Screw terminals for the same
■
Power circuitry for 12 V to 5 V dc conversion
■
PMIC for 12 V to 5 V dc conversion (not populated)
The primary functional blocks of this Shield Kit are the four transceiver circuits: two CAN transceiver
circuits and two LIN transceiver circuits. Each of these transceiver circuits enables a digital CMOS
PSoC device to interface with a physical CAN or LIN bus, respectively. Without these transceiver
circuits, it is impossible for CMOS devices to communicate with other CAN or LIN nodes on a CAN
or LIN bus.
The LEDs functional block consists of three active-low LEDs that can provide indications. These
LEDs are driven by PSoC pins. The Arduino connector connects the configured PSoC I/O pins to the
various circuits on the Shield board.
