TJA1152 Configuration

stevenlutz — Tue, 21 Jan 2025 02:35:54 GMT

Where can I find the documentation on the TJA1152?
I'm using the MCXN947 flexcan interrupt transfer demo but need to whitelist CAN ID 0xDF80502 as well as others preferably with a mask?
or maybe disable security features all together on TJA1152.

Some direction on how this is done would be really helpful. Even if it's just the guide on the TJA1152 commands and configuration.

Hello @stevenlutz ,

Thanks for your post.

Please refer to the product page of TJA1152 on the NXP official website: TJA1152 Secure HS-CAN Transceiver | NXP Semiconductors
There are several documents related to TJA1152 available on this page.

And you can also refer to the Secure CAN Demo Using TJA115x Transceivers | NXP Semiconductors.

Hope it can help you.

BRs,

Celeste

None of those documents available are the reference manual that I was looking for. However, I have realized that the tja1152, while supported in the can demo, isn't actually used, which is now taking me back to the unresponded post / issue here

Please help. Thank you.
