Board features
The main features of FRDM665CANFDEVB are:
• CAN and CAN FD
• Onboard transformer isolation for TPL communication to BCC devices
• Configurable VIO voltage
• Configurable VDD5V from internal and external supply
• DIP switch for configuring the arbitration baud rate and CAN ID (ID0_STB_OD, ID1,
ID2 and ID3) of MC33665A
• Reset switch
• LED display for the status of power
• Connectors for external interface to general-purpose input/output (GPIO) and I2C-bus
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 CANFDEVB 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 (ID0_STB_OD, ID1, ID2 and ID3) and CFG (CFG0
and CFG1) 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.
