Technical Data
6.3 Classical CAN Interfaces
Number of CAN
interfaces
CAN-PCI/402-2: 2x CAN high-speed interfaces (CAN0, CAN1)
CAN-PCI/402-1: 1x CAN high-speed interface (CAN0)
CAN-PCI/402-4/2Slot: 4x CAN high-speed interfaces (CAN0 - CAN3)
CAN-PCI/402-1-LP: 1x CAN high-speed interface (CAN0)
CAN controller
esdACC in EP4CGX Altera FPGA,
according to ISO11898-1 (CAN 2.0A/2.0B)
Physical Layer
physical layer according to ISO 11898-2,
bit rate up to 1 Mbit/s
Bus termination
On-board terminating resistors can be individually set between CAN-H and
CAN_L via jumpers, resistance: 120 Ω ±5%, 250 mW
Electrical isolation
electrical isolation via digital isolator and DC/DC-converters is possible:
voltage over CAN isolation
(CAN to slot bracket/EARTH;
CAN to host/system ground;
CAN to CAN): 1000V DC @ 1s (I < 1 mA)
CAN-PCI/402 versions are available with and without electrical isolation.
See “Order Information” on page 41 for further information.
Connector
1x 9-pin DSUB per CAN channel, male

6.4 CAN FD Interface (CAN-PCI/402-2-FD only)
Number of CAN FD
interfaces
CAN-PCI/402-2-FD: 2x CAN FD interfaces (CAN0, CAN1)
CAN controller
esdACC in EP4CGX Altera FPGA,
according to ISO11898-1:2015
Physical Layer
physical layer according to ISO 11898-2,
CAN bit rates from 10 kbit/s up to 8 Mbit/s with the same CAN transceiver
INFORMATION
Please note that the increased CAN FD bit rate (up to 8 Mbit/s,
formerly 5
Mbit/s
) is only ensured for products with batch numbers
as specified in the table “Hardware” on page 3.
Bus termination
On-board terminating resistors can be individually set between CAN-H and
CAN_L via jumpers, resistance: 120 Ω ±5%, 250 mW
Electrical isolation
electrical isolation via digital isolator and DC/DC-converters is possible:
voltage over CAN isolation
(CAN to slot bracket/EARTH;
CAN to host/system ground;
CAN to CAN): 1000V DC @ 1s (I < 1 mA)
Connector
1x 9-pin DSUB per CAN channel, male
Compatibility
The CAN FD interfaces are fully backwards compatible with Classical CAN
Applications!
