Hardware user manual for FRDM665CANFDEVB

messages from the microcontroller to four different TPL ports. It is designed for use in

both automotive and industrial applications. The device can route both TPL2 and TPL3

messages with CAN (FD) communication. FRDM665CANFDEVB is an ideal board for

rapid prototyping of MC33665A for interface to MCU.

FRDM665CANFDEVB supports both classical CAN or CAN (FD). Differential

communication to daisy chain devices can be established with four different TPL ports.

4.2 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
