I am designing a device based on S32K148-T-Box Reference Design, by my design I need to develop CAN communication with 125 KBd (Low-Speed CAN that should meet ISO 11898-3 ).
There are 3 CAN interface on the Reference design, TJA1044GT/3 , TJA1043TKY, and UJA1131HW/FD/5V/0 (SBC), there are 3 questions:
1) can I use one of the above ports to communicate with low speed 125KBd, and which one prefered?
2) Should I replace one of TJA1043TKY or TJA1044GT/3 with another chip that support 125KBd (ISO 11898-3)?
3) if answer to question 2 is yes, which part number I can use?
Thank you for your support.
The ISO11898-3 is a different standard and the TJA1055 is supporting that one. It is so called Fault tolerant CAN
I am afraid that TJA1043 does not support that standard.
Have you considered using the TJA1055T: Fault-Tolerant CAN Transceiver?
The TJA1055 is the interface between the protocol controller and the physical bus wires in a Controller Area Network (CAN). It is primarily intended for low-speed applications of up to 125 kBd in passenger cars.
Please let me know if you need any further recommendation.
Thanks for reply,
Actualy, TJA1055T (golden Chip) is a very good suggestion, but before changing the PCB design I prefer to know if I can use TJA1043TKY at first, So, any Idea about how to use TJA1043TKY to support ISO 11898-3?
