Starter Kit for V850E2/FG4-L User Manual
The operation modes of the LIN transceiver can be controlled by jumper CN9:
Jumper Position Description
1 – 2 Sleep disabled CN9
3 - 4
Local wake-up input
(negative edge
triggered)

Please refer to the LIN transceiver’s data sheet for details.
2.4.4.2 CAN Interfaces
CAN transceivers, IC24 and IC25, are supplied to provide two CAN bus interfaces. Each
transceiver is connected to one of the microcontroller’s CAN interfaces (FCN0, FCN1). The CAN
bus interfaces are connected to the DB9 connectors CN17 and CN19 (not assembled on starter
kit). Jumper CN10 provides additional CAN bus interface configuration options including the
ability to selectively interconnect CAN bus interfaces on-board.
In order to achieve CAN bus communication, it is necessary to supply the transceivers with a
nominal 12 volt supply voltage in addition to the I/O voltage. This can be achieved by connecting
12V DC to CN13 Pin1.
Connector Position Description
1 External 12V supply CN13
2 Ground
Table 16. CN13 – External 12V supply CAN
Caution: Ensure to NOT connect 12V DC to CN18 pin 1. This would create an overvoltage
condition for all electrical devices on the Starter Kit and will lead to irrecoverable
damage!
Note: The Starter Kit’s supply voltage must be chosen with 5.0V to operate the CAN transceivers.
