Hardware user manual for FRDM665CANFDEVB
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 I
2
C pins of MC33665A.
