Hardware user manual for FRDM665CANFDEVB
messages. FRDM665CANFDEVB is an ideal board for rapid prototyping of MC33665A
for CAN FD interface to MCU.
FRDM665CANFDEVB supports both classical CAN or CAN FD. Differential
communication to daisy chain devices can be established with four different 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 of MC33665A
•
Reset switch for the device and board
•
LED display for the status of power
•
