MPC5777M:MCAN non-ISO,Is there a difference about of non-ISO and ISO CAN FD?

[chenyandong]

MPC5777M has 4 Mcan,The M_CAN performs communication according to the CAN protocol specification 2.0 part A,B and to CAN FD 1.0.

For example，MPC5777C: ISO CAN FD

Is there a difference about of non-ISO and ISO CAN FD?

What is the ISO can FD version? CAN FD 1.x？

Hi,

For example, see short explanation here

https://can-newsletter.org/engineering/standardization/141209_iso-can-fd-or-non-iso-can-fd/

Once ISO CAN FD and non-ISO CAN FD devices are connected to the same network, the CAN FD feature must not be used due to different protocol/frame format. The Classic CAN mode is unaffected.

Hi,

In MPC5777M Reference Manual, Rev. 4, 04/2015

"The following are the features of Modular CAN Cores.

Conforms with CAN protocol version 2.0 part A, B and ISO 11898-1

CAN Flexible data-rate (CAN–FD) protocol with maximum 64 data bytes on"

In CAN Newsletter - ISO CAN FD or non-ISO CAN FD 

"in future all products will be compliant to the ISO standard (ISO 11898-1)."

"All products compliant to the upcoming ISO standard 11898-2:2015 should be called “ISO CAN FD”. Products implementing Bosch’s original protocol should be named “non-ISO CAN FD” "

So,Please check it for me, MCAN interface in MPC5777M is ISO can FD or not?

" ISO 11898-1" in MPC5777M Reference Manual is ISO11898-1 FDIS 2014 or not?

The MPC5777M follows original non-ISO CAN FD implementation.

There will be no update on the MPC5777M.

The MPC5775K and MPC5777C offers MCAN that complies with latest ISO CAN FD.

It is summarized here https://community.nxp.com/message/894350.

where can I download the symbol of MPC5777C?

Thank you.
