4.4 Board description
The FRDM665CANFDEVB allows the user to prototype and test all functions of the
MC33665A gateway router with CAN or CAN FD communication.
CAN or CAN FD communication can be established with MC33665A via sub-D9
connector. In addition to sub-D9 CAN connector, same signals of CANH and CANL are
available in both power and CAN connector J6 and CANEVB interface J10. TJA1443 is
the CAN transceiver used for FRDM665CANFDEVB.
12 V (> 5 W) DC power supply can be connected to J6. VDD5V selection and VIO
selection have no influence in FRDM665CANFDEVB as there is a constant 12 V power
supply and there is no direct microcontroller to select VIO. CAN ID can be selected by
setting the position in DIP switch SW2. Take care to set the position of DIP switches
(SW2) appropriately to configure ID and CAN arbitration baud rates to MC33665A.
External 5 V can be connected to bypass the VREG circuit of MC33665A. Take care in
selecting the appropriate jumper J8 to power the VDD5V.
Connector J1 gives the option to access the GPIO and I2C pins of MC33665A.

FRDM665CANFDEVB.

5 Configuring the hardware
FRDM665CANFDEVB can be configured as stacked board to S32K344EVB.
5.1 CAN FD interface
FRDM665CANFDEVB can be connected to a PC/laptop or other ECUs with
power and CAN cable or connector. 12 V supply line can be used to power the
FRDM665CANFDEVB, female sub-D9 connector can be interfaced to relevant CAN tool
or ECU. SW2 can be used to configure the CAN ID for MC33665A. CFG pins can also be
configured to set the arbitration speed for MC33665A. Press SW1 button (RST switch)
after changing any settings on SW2 (ID and CFG). Ensure the settings on J8 for VDD5V
and J13 for VIO selection are appropriate for power supplied to the board. CANEVB
interface J10 can be used for direct interface with S32K344EVB for CAN or CAN FD.
