CAN FD Support

automationworld · ‎2025-01-07

Hello, I am looking for a MPU as CAN FD master but couldn't find the type with explicit CAN FD support. I would inquire here to make sure I haven't missed any details, and also ask for more information about the availability of the high performance chip with CAN FD interface. Thank you!

Hello,

Looking at STM32MP131 datasheets, there is no CAN support at all neither FDCAN nor CAN2.0.

And indeed in the product page it shows the unvailability of CAN/FDCAN on these devices:

Unlikely to STM32MP157 or STM32MP135 which have two FDCAN instances each .

Example of STM32MP135 in the product selector:

And I confirm there is an issue in the Peripheral naming it needs to be FDCAN not CAN 2.0.

Hope it's clear now.

Hello @automationworld and welcome to the Community.

STM32MP157 has two FDCAN instances.

From the datasheet:

Are you sure you are looking for a MPU product not MCU?

Thank you and really appreciated! I missed digging into the datasheet. My question came from the high level product selector at MPUs intro page doesn't explicitly show CAN FD option but only CAN 2.0.
