interface

The    calibration board is equipped with one ST L9616 High-Speed Transceiver. It provides 
the Controller Area Network (CAN) communication interface through the SPC563M64xx 
CAN interface for calibration via CAN. This serial communication can reach speeds up to 
1Mbps.

Figure 12.

CAN schematic diagram

Two jumpers (J12 and J13), allow to select between the two FlexCAN interfaces of the 
SPC563M64xx mcu.

         

The CAN channel is terminated with a 120 ohms

 

resistor. Moreover, a protection circuitry 

has been designed to protect the CAN transceiver in high-speed and fault tolerant networks 
from ESD and other harmful transient voltage events (see 

Figure 12

).

The L9616 CAN transceiver has an Adjustable Slope Control (ASC) feature that sets the 
slope speed using its ASC pin. This feature select the modes of operation:

●

low speed (CAN baud rate up to 250kBaud)

●

high speed (CAN baud rate from 250kBaud to 1000kBaud)

This pin can be put to high or to low by the cut trace options J6, J17 & J7 as described in 

Table 9

.
