SE052 Multiple Session

MohitGediya — Fri, 08 May 2026 11:29:17 GMT

Good evening community,
I am creating one zephyr-based project and include Nano-Plug and Trust module.
I use FRDM_KE17z512 board, SE052 IC.

Let me know, can I able to communicate two SE052 ICs(same ICs) at the same time with one Carrier board.
Is this supported with my software and hardware set-up?
Also i want to authenticate crypto object which is non-deletable(remove delete policy at creation time), may i able to read that object again for data encryption.
In that i use AES symmetric key with cbc mode algorithm.

Hi @MohitGediya ,

Do you mean you want to communicate with the two SE05xes with the same slave address on the same I2C bus? Which use case needs two SE ? Please kindly clarify.

Best Regards,

Kan

On same I2C slave address is possible then how to two different operation will perform at same time over 2 different ICs?
Or can I use two different I2C peripherals, What is best option for production?

Can i use one I2C peripheral of physical carrier board?
Can i create two different sessions at same time to communicate with two ICs?

Hi @MohitGediya ,

I see, but if you want to open two different sessions at same time to communicate with two ICs, please make sure they are on different I2C buses, for example, one SE050 is on "/dev/i2c-1" , and the other is on "/dev/i2c-2".

Hope that makes sense,

Have a great day,
Kan

I am use Zephyr rtos based platform, Should i open other session to communicate with ICs?
For each IC communication, should i open dedicated I2C session? How to manage?

If i want to open one AESKey session and one ECKey session in same IC.
Then can i open in two different sessions nano plug and trust module?
